Oxygen Absorber Packets for Long Term Food Storage

When you are dealing with food, food containers, etc., moisture and dealing with oxygen levels can be a task in itself to tackle. Thus oxygen absorbers can come to the rescue and help absorb any moisture/extra oxygen in the packaging. If these levels are not managed, the food product may be spoilt and lose its structure.

But to understand how to use them in your packaging and understand all do's and don’ts while using Oxysorb - Oxygen absorber we shall continue reading this post. We will also learn how this product can really help protect various products and packaging from the harm caused by excessive oxygen.

What To Do When Using Oxysorb/Oxygen Absorbers?

When it comes to knowing what you can do when you are using an oxygen absorber, you should be well-informed before you begin use. So, let us first understand these points that you need to keep in mind when using Oxysorb in your packing needs.

Selecting the right and suitable absorber type

The components of an oxygen absorber sachet can greatly vary, depending on what it is being used for. Thus it is essential to choose the right one for your packaging needs. The best suitable absorber type can make all the difference and make sure there are no moisture or water vapor-related problems during shipping.

There are many different types of oxygen absorbers available but their base components are activated carbon, iron powder, sodium, etc. So, make sure you choose the right, suitable oxygen absorber like Oxysorb.

Gauging absorber capacity needed as per container volume

You need to gauge the amount of absorber/Oxysorb needed to keep your contaminants safe during transit and make sure that they retain their freshness, and structure and are free from any harm. Thus the right amount of oxygen packets Size needs to be used for that particular container volume so that there are no mishaps.  If you choose to use a very small amount, then the changing moisture levels may not maintained by oxygen absorbers.

Using air-tight containers for food packaging

Usually, air-tight food packaging can help keep food items fresh and edible for much longer, as compared to regular plastic packaging. And, when you use oxygen absorbers for food along with an air-tight container environment, you are making sure that there is no excess moisture or any re-entry of oxygen inside the packaging. It will help improve its shelf-life dramatically and retain its freshness.

Use mainly for dry foods only

Oxygen absorbers work best when used to protect dry food items such as dehydrated fruits, pasta, pulses, grains, etc. These food items already have less to nil moisture content in them, thus can retain their form and structure well during transit with the help of oxygen packets. Oxysorb can help reduce the oxygen content in the container, and help prevent mold growth, oxidation, and other forms of decay in the containment

Store Oxysorb in a cool, dry space when not in use

Since Oxysorb is an oxygen absorber, it is best stored in a cool, dry space, free from any moisture or exposure to external elements when not in use. If these unused oxygen packets are exposed to moisture prematurely, they can compromise their effectiveness when it is time to actually use them.

What Not To Do When Using Oxysorb/Oxygen Absorbers?

Now that we know what we need to keep in mind when using Oxysorb, you should also be aware of the don’ts of using Oxysorb/oxygen absorber packets. Do make sure you follow these pointers too as they are essential to know when using how they can help avoid any limitations when in use.

Don't reuse absorbers

This is one of the most important pointers to remember. You should not attempt to reus'e Oxysorb sachets. Oxysorb oxygen absorbers are designed to be effective for a single use only. Once these sachets come into contact with air/oxygen, they immediately serve their purpose and thus cannot be reused. They can also pose safety issues later on, particularly, for small children/pets, and may lead to some serious health complications in humans.

Not for use in liquids or wet food items

Oxygen absorber packets work best in dry foods only and should be completely avoided in wet/damp or liquid food items. Since one of the main components of oxygen absorbers is iron powder, it may react or get absorbed in the liquid food item and cause harmful reactions. Oxysorb may also end up oxidizing prematurely upon contact with moisture and clump up inside packaging.

Don't mix absorbers with desiccants

Though these two serve complementing purposes in protecting packaging, it is advised not to mix oxygen absorbers for food together in the same container. There may be some unavoidable and unprecedented chemical reactions, and as a result, this may turn harmful. Sometimes, this may also lead to the fact that the effects of oxygen absorbers will be neutralized, meaning, they won’t be as effective in their absorbing powers and capabilities.

Don’t overload the containers and leave room for airflow

It is essential to make sure not to overcrowd the food containers and use them to the maximum potential, as there needs to be a stipulated amount of airflow in the containers. This airflow is necessary for ideal transportation and retaining the effectiveness of the food items in transit. Proper air circulation is also essential for the oxygen absorber packets to function optimally in maintaining the correct levels of oxygen in the containers.

Dont use in poorly packaged items

When you use Oxysorb in poorly packaged food items, they cannot perform effectively in maintaining proper oxygen levels in the packets. There will be a change in moisture levels as well as oxygen levels and thus the level of effectiveness of these oxygen absorbers can fall drastically. Make sure the container is filled with items with proper, sealed packaging only to avoid these negative side effects.

Making sure you are adhering to these do's and don’ts while using Oxysorb - Oxygen absorber, can help you make use of it effectively and reap all the oxygen absorber packets uses and benefits to the fullest.

Due to their capacity to regulate moisture levels and preserve product freshness, desiccants play an important part in food packaging.

The main cause of food items rotting and degrading in quality during transport is moisture and oxygen. Desiccants such as silica gel packets or oxygen absorbers effectively soak up excess moisture and oxygen, protecting food from microbial growth and preserving its texture, flavor, and nutritional value.

Desiccants also assist in extending the shelf life of food, lowering food waste, and enhancing consumer safety, thus making it crucial for food packaging.

Silica Gel for Food Packaging

Silica gel is frequently used in food packaging to regulate moisture levels and maintain product freshness. Silica gel, despite its name, is actually a porous form of the natural mineral silicon dioxide. It has a high adsorption capacity, which enables it to draw and retain water molecules and keep the packaging environment free of moisture.

Applications of Silica Gel in the food and beverage industry

Silica gel finds numerous applications within the food and beverage (F&B) industry due to its various advantages. In this industry, silica gel is mostly used for:

  1. Desiccant for Packaging: Silica gel packets are commonly found in various food products, such as jerky, dried fruits, and certain condiments. They help to absorb excess moisture, preventing the growth of microorganisms and maintaining the product's texture, flavor, and quality.
  2. Chocolate and Confectionery: Silica gel is employed in the chocolate and confectionery industry to prevent the formation of sugar bloom, which occurs when moisture causes sugar crystals to migrate to the surface of the chocolate, resulting in a dull appearance and altered texture. Silica gel helps maintain the desired texture and appearance of chocolates.
  3. Medicinal and Edible Salt Packets: Silica gel packets are sometimes added to containers of medicinal or edible salts to prevent clumping caused by moisture absorption.
  4. Seeds and Horticulture: Silica gel can be used to extend the viability and germination rate of stored seeds. They are also used in seed banks and horticulture applications to maintain seed quality.
  5. Beverage Packaging: Silica gel can be used in the packaging of powdered beverages, such as instant coffee and powdered tea. It helps prevent clumping and ensures that the powder remains free-flowing.

Oxygen Absorbers For Food Packaging

Oxygen absorbers work like food preservatives – they enhance the shelf life of food and help them stay high quality for longer. They are crucial in stopping decay from the oxygen in the packaging environment acting on the food products. Oxygen facilitates the growth of spoilage bacteria and oxygen absorbers act against it, thus keeping the food items fresh for longer.

Oxygen absorbers offer a significant advantage by preserving the taste, visual appeal, and aroma of different food items.

Oxygen Absorbers – Two Main Types

Type B and Type D absorbers are the two primary types of oxygen absorbers used for food storage. To function properly, Type B absorbers need some moisture from the food they are packed with, such as partially dried dry fruits.

On the other hand, Type D absorbers are appropriate for drier materials because they do not require external moisture to activate and can do so more quickly.

Type B absorbers can last for about a year, whereas Type D absorbers expire after six months.

Oxygen Absorber Packets - Applications

Oxygen absorber packets contain iron powder, which when combined with oxygen, absorbs more oxygen out of the air. Due to their capacity to stop spoiling food, maintain freshness, and increase the shelf life of food and medical items, these packets have a wide range of applications.

  1. Grains and Cereals: Grains and cereals are susceptible to infestation by pests and insects, especially in the presence of oxygen. Oxygen absorbers can create an oxygen-deficient environment that inhibits the growth of insects and extends the shelf life of these products.
  2. Spices and Seasonings: Spices and seasonings contain volatile compounds that can deteriorate due to exposure to oxygen. Oxygen absorbers can help maintain the potency, flavor, and aroma of these ingredients.
  3. Processed Meats: Oxygen absorbers are used in the packaging of processed meats like jerky and sausage to prevent oxidative rancidity and spoilage, thus extending the products' shelf life.
  4. Dairy Products: Oxygen absorbers can be used in the packaging of powdered dairy products like powdered milk or powdered cheese to prevent oxidation and maintain the quality of these items.

Silica Gel VS Oxygen Absorbers

Silica gel and oxygen absorbers are both popular food preservers used for packing the quality and freshness of diverse food products. Let’s mark the main differences between them.

1. Composition: Oxygen Absorbers usually contain iron fillings, clay, and salt. When these ingredients come in contact with air, they absorb oxygen from the atmosphere. Silica gel packets contain silicon dioxide and act as a moisture absorber, thus keeping items dry and fresh.

2. Usage: Oxygen Absorbers are used to preserve and store food items by eliminating oxygen, which prevents spoilage and helps in pest control. However, Silica Gel reduces humidity in the packaging environment, protecting items from moisture damage and mold growth.

3. Reusability: Oxygen Absorbers are of one-time use after activating them for some time. Silica Gel can be reactivated with heat, and therefore, is cost-effective in the long run.

4. Compatibility: silica gel and oxygen absorbers have distinct roles in preserving products, they are often used together to address both moisture and oxygen-related concerns. The choice between the two, or the decision to use both, depends on the specific needs of the product and its packaging requirements.

5. Safety for food packaging: Oxygen Absorbers are effective for preserving nuts, grains, dry fruits, and other food items. For food packaging, only food-grade silica gel is safe.

Silica Gel or Oxygen Absorber Packets – Which Is Better?

Even though oxygen absorbers and silica gel have different functions, they are both essential for packing and preservation. In order to select the right desiccant between the two, each of their properties have to be considered.

 Oxygen Absorber Packets for Long Term Food Storage

Packed food and ready-to-eat food packets are an integral part of modern living that cannot be ignored. Thus, the shelf life of this packed food becomes a critical aspect of the food-related industry. This shelf life indicates a duration when the product can be stored and consumed. During this duration, the product’s quality, nutritional value, and safety are all within check. So that products remain fresh, it is important that their shelf life is extended as otherwise there is more chance of waste or that the product does not meet the regulatory requirement or may not meet the customer’s expectations. Towards this end, one commonly used solution is through the use of oxygen absorbers. They play a significant role in the preservation of the quality as well as the integrity of packed food products and food packaging.

An oxygen absorber for packed food is quite simple in design. They are small packets that contain a mix of iron powder, activated carbon, and sodium chloride (salt). They are designed to remove oxygen from the environment when they are placed in a sealed container or packet. These O2 packets follow a chemical process where the oxygen absorbers remove oxygen and this is known as oxidation. The iron powder that is within the oxygen absorber will react with the oxygen that is in the air and this forms iron oxide or rust which is a by-product. This reaction takes place due to the effect of moisture and so moisture-absorbing materials are packed with the oxygen absorber for packed food. Though the oxidation process produces heat i.e. it's exothermic, the heat is minimal and so the packaging material does not ignite, and neither does the food packaging affect the food product.

O2 packets are available in various sizes and types on the basis of the appreciation and also the volume of the oxygen that has to be absorbed. Oxygen absorbers for packed food are usually iron-based and work well for the packaging of general food. However, when it comes to food or pharmaceuticals, there are specialized absorbers that are required. The sizes too vary from small sachets to larger packets that can be used for bulk storage containers. Therefore it is essential that the right size and type is selected on the basis of the specific requirements and how much optimal oxygen removal is required in order to prolong the product’s shelf-life.

Benefits of Using Oxygen Absorbers in Packed Foods

Oxygen absorbers for packed food provide many benefits. At the most basic level, they extend the shelf life since they remove oxygen from the packaging since oxygen is the main factor that causes the deterioration of food. This is the oxidation reaction that leads to spoilage. When the levels of oxygen are reduced the oxygen inhibitors inhibit the growth of microorganisms as well as delay the degradation process of oils and fats. Furthermore, the oxidation of flavours, colours, and vitamins is prevented as well. Thus, the freshness of the food product as its quality is extended.

The presence of oxygen affects the sensory and quality attributes of packed foods. Through oxygen absorbers, the oxidation of fats is prevented and thus, the freshness, flavour, and texture are preserved. Since the taste, appearance, and aroma are retained customers would be satisfied. Oxygen absorbers for packed food contribute towards food safety as they prevent bacteria and microorganisms from spoiling the food. Due to the reduction of oxygen, the environment is made unfavourable for the survival or growth of these microorganisms and so chances of contamination or food-borne illness are reduced.    


Since the shelf-life is preserved as is the freshness and quality of the food, food waste is minimized due to oxygen absorbers. When products have an extended shelf-life they would not spoil or deteriorate prematurely. Thus, food waste is reduced as less food needs to be discarded. Thus, this is not only cost-effective but environmentally sustainable. Furthermore, oxygen absorbers for packed food are versatile and can be used in many types of ready-to-eat packets for snacks, baked foods, processed meat, dry goods, etc. Also, these are adaptable to various types of food packaging like bottles, cans, and pouches as versatile solutions for various food packaging applications.

Food packaging is the only place where oxygen absorbers are used. Though they are primarily used in food packaging there are other industries too which benefit from their use. In the food industry, they work towards the preservation of the flavour, nutritional value, and overall quality of the food. This includes baked goods, dried fruits, snacks, processed meats, and spices in which these oxygen absorbers are used for packed food. Nutraceuticals and pharmaceuticals are oxygen-sensitive and thus, oxygen absorbers prevent the degradation of these products due to oxidation of their active ingredients and this ensures the continued efficacy and potency of the products.    

There are also medical devices that are oxygen-sensitive like test strips, pharmaceutical packaging as well as diagnostic kits. Oxygen absorbers help in maintaining their integrity as well as their stability. Thus, the application of oxygen absorbers is primarily used where a controlled environment is required and oxygen needs to be removed. The quantity of oxygen absorbers would depend on the volume as well as the type of food packing and the food product whether they are dry goods like pasta, grains, etc, snacks, or meat products, the quantity would change accordingly.

Thus, oxygen absorbers have varied uses in packed food products from the extension of their shelf-life to improved quality, reduced food waste, and an enhancement of safety.  By minimizing the presence of oxygen the absorbers help to preserve the nutritional value, freshness, and taste of the products so that customers are satisfied with the product’s quality.

  2. Calculate the Right Amount of Oxygen Absorbers: The number of oxygen absorbers that you need depends on the volume of the container and the type of food that you are storing.A general rule of thumb is to use 300 CC of oxygen absorbers per gallon of pet food.

  1. Add the Oxygen Absorbers: Once you have calculated the number of oxygen absorbers that you need, add them to the container before you add the pet food. Make sure that you seal the container immediately after adding the oxygen absorbers.
  2. Label and Store the Container: Label the container with the date of storage and the type of food that you have stored. Store the container in a cool, dry, and dark place away from direct sunlight and heat sources.

Using OxySorb-oxygen absorber packets to store pet food has many benefits. First, it significantly extends the shelf life of the food. This is especially important for pet owners who prefer to buy pet food in bulk. Second, it helps preserve the freshness and flavour of the food, ensuring that your pet enjoys every meal. Finally, it reduces the risk of foodborne illnesses caused by bacteria and other harmful microorganisms.

However, it is important to note that oxygen absorbers are not a substitute for proper food handling and storage practices. You should always check the expiration date of the pet food before storing it, and discard any food that has passed its expiration date.

How do OxySorb-Oxygen Absorbers work?

Oxygen absorbers work by removing the oxygen from the air, which helps to prevent the growth of bacteria and mould. When any pet food is exposed to oxygen, it can become rancid and spoil quickly. An oxygen absorber helps to create an oxygen-free environment where bacteria and mould can’t be addressed, which helps to keep the food fresh for a longer period of time.

How to Use OxySorb-Oxygen Absorbers with Pet Food?

When using food-grade oxygen absorbers for all pet food, it’s important to follow a few guidelines to ensure that they are effective. First, make sure that the oxygen absorber packet is the correct size for the container you are storing the pet food in. Each type of storage container requires different sizes of oxygen absorbers such as 20 CC (smallest available size) for absorbing less oxygen from the small storage containers and 3000 CC (biggest available size) for excessive oxygen from large storage containers.

Finally, make sure that the pet food is dry before storing it with an oxygen absorber. Moisture can interfere with the effectiveness of the oxygen absorber, so it’s important to remove as much moisture as possible from the pet food before storing it.

Benefits of Using OxySorb-Oxygen Absorbers with Pet Food:

There are several benefits to using OxySorb with pet food. First, it helps to extend the shelf life of the food. Pet food that is stored with food-grade oxygen absorbers for pet food will stay fresh for a longer period of time, which can help to save you money in the long run.

Second, it helps to maintain the nutritional value of the pet food. When any pet food is exposed to oxygen, the nutrients in the food can begin to break down. By removing the excess oxygen from the environment, the nutrients in the food are preserved, which helps to ensure that your pet is getting the best possible nutrition.

Finally, using OxySorb for pet food can help to prevent the growth of bacteria and mould. This can help to keep your pet healthy and prevent foodborne illnesses.

If you’re looking for a way to extend the shelf life of your pet’s food and maintain its nutritional value, using OxySorb-oxygen absorbers is a great option. Removing the oxygen from the environment and the food-grade oxygen absorbers for pet food can help to prevent the growth of bacteria and mold, which can help to keep your pet healthy.

Makhana is a type of puffed lotus seed that is popular in India and the Himalayan countries. It comes in several varieties, including plain, spiced, and sweet. Plain makhana is roasted and has a nutty flavour, while spiced makhana is mixed with spices like cumin, coriander, and red chili powder. Sweet makhana is coated with sugar, jaggery, or honey. 

How is makhana stored? 

Whether you enjoy it as a snack or use it for other purposes like cooking, it is crucial to know how to store and preserve makhana properly. In addition, some specific steps must be taken to ensure their freshness and quality.

One popular method is to roast the makhana before storing them in an airtight container. This helps reduce the moisture content and prevents spoilage. In addition, it increases the shelf life of the makhana by 15 days. However, after 15 days, roast it again, so it's a repetitive process. Eventually, the oxygen inside the container is not eradicated, so that it may cause spoilage to the makhana.

The best methods to store makhana:

In this article, we will discuss how to store and preserve makhana for extended periods without using preservatives or additives so that you can enjoy its crunchy and delicious taste for months together. Preserving makhana can be tricky due to its high moisture content. Fortunately, there are several ways to store or preserve makhana to keep them crispy and delicious. 

By following these methods, you can ensure that your makhana snacks remain fresh and tasty for a long time.

  1. Store makhana with Oxygen Absorber 

One of the best methods is to use an oxygen absorber such as OxySorb, which absorbs the oxygen in the container and preserves the makhana for extended periods. You can also add a few oxygen absorbers to your content which will further prevent spoilage by absorbing any remaining oxygen inside the container. This helps remove any residual oxygen from the container that might cause premature spoilage of the makhana.

  1. Store makhana with silica gel 

It is possible to store makhana with silica gel. To do so, you'll want to ensure that the silica gel is dehydrated before using it. Place the makhana in an airtight container, and then add some of the dry silica gel. Seal the container and store it in a cool, dry place. This should help keep the makhana fresh for extended periods.

  1. Store makhana in a vacuum seal

Makhana in a vacuum seal will keep it fresh and crunchy for a more extended period. The first step is to ensure the makhana is completely dry before it is sealed. You can spread the makhana on a baking sheet and let it air dry for a few hours. Once the makhana is dry, place it in a vacuum seal bag and press the air to create a tight seal. Next, press all the edges of the bag to create a secure seal. Finally, place the sealed bag in an airtight container and store it in a cool, dry place. 

  1. Store makhana in airtight containers

 Oxygen Absorber Packets for Long Term Food Storage

Jaggery is famous and used as an alternative to sugar in many parts of India. Jaggery is a type of unrefined sugar made from palm and sugarcane sap. It is primarily produced in various parts of Asia and Africa.

How is jaggery made?

Jaggery is usually made from concentrated sugarcane juice. There are two types of jaggery, one made from sugarcane and the other one made from the palmyra palm tree. In making jaggery, the sugarcane sap from palm trees is boiled for hours, and then we obtain the concentrated liquid. The liquid is then poured into the moulds to dry and settle properly. After the liquid is completely dried, it is packed in boxes and delivered to stores.

Jaggery is also categorised into two different colour types: pale gold and deep brown. The colour range depicts the sweetness of the jaggery. It has been said the darkest variety is the purest form and therefore has the best flavour and sweetness than other jaggeries. 

Palm jaggery vs jaggery:

Both have different tastes. Palm jaggery is generally made from coconut juices. The jaggery is made from palm tree extracts and has several numbers of vitamins and minerals contained inside. However, palm jaggery is a rich source of essential minerals, restores healthy digestion and gives relief from constipation.

Whereas normal jaggery is made from sugarcane juice, detoxes the liver, and activates digestive enzymes in the body. Jaggery also purifies the blood and boosts immunity. Jaggery is generally made by extracting sugarcane sap, obtaining concentrated sugar, and molding it into different shapes.

Can jaggery get affected by fungus?

As per studies, jaggery has moisture and carbohydrates. This combination makes the jaggery ideal for breeding fungus in it. It has been said that if jaggery is not preserved with preservatives and chemicals, it is more likely to have fungus growth. Fungus growth rises, especially during summers. Jaggery is made during winters, with 5% moisture inbuilt in jaggery. The humidity content helps retain the taste and colour of the jaggery and even helps increase the product's shelf-life. However, summers can also result in melting the jaggery. The growth of fungus in jaggery can be prevented by using food-grade desiccant like an oxygen absorbers and the silica gel packets. These can be filled together or individually, while packing the jaggery.

A study conducted on commercial jaggery observed the effect of storage period on the quality of jaggery. Experimental data revealed that moisture content in jaggery could be increased from 12.07% to 22.36% in open storage, decreasing to 9.23% in bin storage. Lastly, while packed in plastic bags, moisture content was increased to 15.84%. This also results changing in the colour of jaggery. Therefore, the colour of the jaggery becomes darker during storage. 

Furthermore, jaggery's optical density and acidity were slightly increased during storage. So, to maintain the quality of jaggery, an oxygen absorber and silica gel packets must be stored with an oxygen absorber.

How is jaggery stored? 

After the concentrated liquid takes its shape and settles down properly, the storing process starts immediately. Jaggery is usually packed in airtight containers in a cool and dry place. It can also be stored by breaking it into small pieces. 

Best methods for preserving jaggery:

  1. Storing in zip-lock bags: The zip-lock bags can keep the jaggery held for at least 1 to 2 years and retain its taste and colour. While storing jaggery, it would be best if you always remembered that no air goes inside the zip-lock bag. Otherwise, the colour and flavour of the jaggery will not be retained and even spoil the shape. If you don't have a zip-lock bag available, you first wrap the jaggery with paper, cover it with plastic, and store it in an airtight container. 
  2. Storing in the fridge: Before storing the jaggery in the refrigerator, never pack it in a plastic box. Always try to store jaggery in a steel container. Storing jaggery in plastic can spoil the colour and taste of the jaggery. At least for 6 months or more, jaggery can be stored if we pack it properly without any moisture or air inside the container. 
  3. Storing in dry leaves: To prevent jaggery from getting spoiled for a long time, you use "Dona", made from dry leaves. Dona should be kept below the jaggery, and the jaggery needs to be fully covered up with Dona. Storing with Dona can protect jaggery for 6 months and more.

As we have read above, there are three types of storing methods, but there is still another better method of using an oxygen absorber for storing jaggery. The absorber keeps the product dry and removes excess oxygen from the packed jaggery. 

Storing with an oxygen absorber and silica gel packets: 

An oxygen absorber is the best for storing jaggery. While packing jaggery, excess oxygen can be stored with the product and can spoil the taste, shape and even the colour of jaggery. So, use an oxygen absorber to avoid damaging jaggery. The absorber will never spoil the taste and colour of the jaggery and will never react with the inside content. 

Oxygen absorbers contain a mixture of iron powder, zeolite powder, salt and water. The absorbers are food grade approved. 

Here are a few reasons to use oxygen absorbers:

  • Extend shelf-life
  • Preserving food without using chemicals or additives
  • They keep unwanted organisms away from the food

Silica gel packets are also beneficial for removing the excess moisture from the stored jaggery packets. Similar to oxygen absorber prevents spoilage of jaggery. Silica gel packets never react with the inside content, whether jaggery or any other food product. It is also said that silica gel is not widely used as an oxygen absorber in the food industry. Silica gel is only preferred for certain dried fruits and dried meat. 

Thus, the oxygen absorber and silica gel packets can be used together to remove oxygen and prevent moisture from jaggery. Both can improve the shelf-life and store jaggery for a long time, compared to other storing methods.

Therefore, here is the answer to storing jaggery for a long time, using an oxygen absorber and silica gel packets. 

Lastly, now you may have got answer to your questions regarding storing jaggery. Using an oxygen absorber for storing jaggery. It is added inside the enclosed packets consisting of jaggery to prevent the growth of fungus and store it for a long time. It also helps in decreasing the oxygen level inside the enclosed container. In addition, the absorber helps retain the food product's taste, smell and structure. 

 Oxygen Absorber Packets for Long Term Food Storage

Oxygen absorbers are a great way to store dry foods and grains over a long period.

What Is An Oxygen Absorber?

An oxygen absorber contains Iron powder, Bentonite clay, and salt within a sealed packet. The seal of these absorbers acts as an oxygen barrier to reduce oxygen and moisture content. The benefit of an oxygen-free environment is that it prevents the growth of insects and their eggs or larvae. This method gives the advantage of not freezing the foods before repackage. It is powerful because it reduces Oxygen to 0.01 %. It ensures there is no chance of food destruction at all.

How does The Oxygen Absorber work?

The oxygen molecules of the absorber interact with the iron particles, and naturally, the iron begins to rust. The next step is to add sodium to the pack, which acts as a catalyst to oxidise the iron even in a low environment of low humidity.

Can You Use Oxygen Absorbers In Following Food and Containers?

Flour- You can use an oxygen absorber to store the bleached white flour. Just remember that the whole white wheat flour will only sustain for twelve months.

Sugar- No, you should not use an oxygen absorber to store white granular sugar. What happens is the sugar will turn into a hard brick. Not only white sugar but do not use this for brown sugar because it has much more Oxygen to be completely absorbed by the oxygen absorber.

Rice-Yes, one can go for an Oxygen absorber to store rice. With the help of this method, you can store the white rice for up to thirty years. You can also use the oxygen absorber for brown rice.

Not only the major food sources but you can also store Sweets, Namkeen, dry fruits, and many other packed foods with the help of an oxygen absorber.

Mason or Glass Jars- You can use oxygen absorbers in mason jars or glass jars for up to ten to fifteen years. It will provide a great oxygen barrier to your food.

Plastic Containers- It is not advisable to use an oxygen absorber for the plastic containers. Plastic allows Oxygen to enter the container and react with the foodstuff even if it is sealed. You might be unable to detect it because it is a very slow process.

Can You Reuse Oxygen Absorber?

Oxygen Absorber should not be reused. Once the packet is exposed to Oxygen, the iron in the package will turn into rust. This is because it will reach its capacity and will no longer be able to reduce Oxygen.

What Are The Foods I Shouldn’t Store With Oxygen Absorbers?

Foodstuffs with a high moisture content or a high amount of fats should be avoided from storing with Oxygen Absorber. The logic behind this process is that it creates the perfect environment for bacterial growth and other infiltration.

How Long Does Reaction Take To Work?

When the absorber is exposed to the Oxygen in the environment, the chemicals begin and get warm as it expands to reduce the Oxygen within a few hours completely.

Is It Alright To Refrigerate Oxygen Absorbers?

There is not any necessity to refrigerate the oxygen absorber. Besides, it has its danger that the frozen environment will destroy its property and might not work effectively.

Can Oxygen Absorbers Kill Bugs and Insects?

It is a common assumption that all packed dry foods or grains are safe, but the truth is most of them have a minute presence that you have no idea about. All the dry foods that are stored for a long period like white rice, and oats have a high chance of the presence of bug eggs in them. This is the reason it is important to repack food while planning for storing long term. Oxygen absorbers can prevent bugs and insects from entering or populating, but they cannot kill or eliminate them. It is safe to use once you are sure of the container.

Why Does It Turn Hard?

Yes, the oxygen absorbers become hard once they reach their capacity. At that stage, it won't be able to remove any oxygen or moisture content from the environment. This time you should consider replacing them.

The oxygen absorbers are environmentally friendly, and non-toxic hence, they can be easily disposable. It is ROHS certified and trusted by our thousands of customers.

 Oxygen Absorber Packets for Long Term Food Storage

Oxygen absorbers are little packets of iron powder. They are non-poisonous and BPA-free, making them safe to be used for food packaging, and utilized to eliminate oxygen from the air (21% oxygen with the rest being generally nitrogen) when packaging the food items. 

Oxygen Absorbers are utilized to eliminate oxygen from inside a sealed environment, creating a nitrogen environment for long-term food stockpiling. In addition, it cuts the oxygen level down to 0.01% or less. So, this signifies the importance of oxygen absorbers usage in packaging food products, but only if it is used properly would they be able to keep your food fresh.

Let's have a look at how to use Oxygen absorbers effectively.

Steps To Start Using Oxygen Absorbers:

Step 1: Prepare your container and food

The containers you will use should be clean and dry before adding the food, and they should be closed immediately.

Step 2: Keep Oxygen Absorbers safe

Oxygen absorbers start absorbing oxygen as soon as it comes in contact with air, so keep them packed inside a mason jar and add them immediately when your container is prepared, and close the lid.

Step 3: Seal the container and label it with the date for your reference

How to use oxygen absorbers


Why Should You Use Oxygen Absorber?

A significant part of realizing how to utilize oxygen absorbers securely is knowing why they are utilized.

Main reasons for using oxygen absorbers while packaging the food items:

  • It helps in increasing the shelf life of the food products (as long as 30 years for most foods in dry form) 
  • To forestall mold and the growth of microorganisms in your food. Nothing will develop without oxygen to benefit from
  • To preserve the foods containing vitamins A, C, and E that get degraded when exposed to oxygen 
  • It prevents browning of freeze-dried fruits
  • It helps to preserve the flavor
  • To kill bug eggs you might find in your food (normally grains). These eggs can't grow without oxygen.

Most foods in dry form have a pretty long shelf life, between 1-5 years, even without using an oxygen absorber. If your food stock is moving fast and doesn't stay in storage areas for long, it can do well without oxygen absorbers, but it's always good to use them for additional benefits.

What Types Of Containers Are Compatible With Oxygen Absorbers?

Since the oxygen absorbers are effective only when it is least exposed to the air, airtight containers are most preferred.

1) Mylar Bags

Mylar bag of 5mil commercial grade is generally used for packaging food, and it is adequate to protect your food from light, oxygen, and moisture. In addition, this opaque bag material is good for packaging photo-sensitive food products. Still, it must be kept inside a food-grade container and rodent-proof as 5 mil is easy to puncture and stands a high chance of getting destroyed by the rodents.

2) Mason Jars

Mason jars keep your food dry and fresh with the advantage of being 'puncture-resistant' and 'rodent-proof.' These jars need to be stored away from sunlight as they are not light-resistant and can also shatter easily with a slight push. Hence, one must be careful while using them in an earthquake zone or with playful children and pets.

3) Metal container with seamed lids

The most commonly used metal container is #10 cans; these are effective at keeping your food protected from moisture and oxygen. They also have an advantage over mylar bags as rodents can't puncture through them and stand the instability caused by earthquakes and kids or pets playing around.

4) Food-grade plastic containers using Mylar bags

Plastic containers are tough enough to get punctured or destroyed by rodents. They are also shatter-proof against any instability created by earthquakes (to some extent) or kids or pets playing around. However, plastic containers are ineffective at keeping moisture and oxygen, unlike other containers and bags for storage. Hence, using mylar bags with plastic containers is an effective combination to keep your food safe.

Also, it is suggested to use Gamma lids in such plastic containers as they help to seal out the oxygen that gets trapped inside every time the container is opened, and putting oxygen absorbers inside allows you to manage the oxygen level fairly well by reducing it down to 0.01% or less. Always check the oxygen absorber's performance and replace it with a fresh one when it has solidified.

List Of Foods That Can Be Stored With Oxygen Absorbers:

Oxygen absorbers can be used to preserve foods that contain 10% moisture or less. Storing the foods in an oxygen reduced environment can lead to botulism poisoning if the moisture and oil content exceeds the permissible limit.

  • Natural cheese and other dairy products
  • Prevents fruits and vegetables from browning due to non-enzymatic process
  • Inhibits oxidation and buildup of red color in most berries and sauces
  • Bread, cookies, cakes, pastries
  • Nuts and snacks
  • Candies and confectioneries
  •  Whole fat dry foods
  • Dried fruits and vegetable
  • Spices and seasonings
  • Flour and grain items 
  • Fresh and precooked pasta and noodles
  • Vitamins 


 Oxygen Absorber Packets for Long Term Food Storage

How does Oxygen Absorbers work?

Fundamentally, oxygen absorbers are effective, modest, and helpful strategies for preserving a wide range of food products with the least changes in fragrance or other negative outcomes, making them an indispensable part of all large food stores. Let us look at how precisely these little marvels can secure your food! It is an unpalatable, tiny packet that can make all the difference to the survival of your stored food.

Why do we need to evacuate oxygen? 

Before discussing how the oxygen absorber functions, let's look at how oxygen affects your food and its quality: for example, the oxygen absorber prevents mold, discolouration, and rancidification in wheat. Foods like spices, meats, grains, and nuts are prone to turn rancid in oxygen. Trapped oxygen inside food packets causes spoilage of fats, oils, and other similar compounds, leading to a bad odour associated with those decayed food items.

It prevents the development of mold in highly prone food items.

Even though very few molds are anaerobic (can endure even without oxygen), most need some oxygen while they are in the growth stage. Oxygen absorbers can't eliminate all the oxygen (at one point, there would be a small amount of oxygen that is minuscule to react with the packet), but they can eliminate a significant part that can further lead to the development of mold in large numbers. It diminishes the chances that those toxic moulds stand to ruin your stocks.

Oxidized foods lead to the development of odd tastes.

Oxygen reacts with the food in varying ways often, by destroying and staining the food and turning it horrible while it is chemically sound for eating (whereas such components won't cause any harm if somebody eats it but it is still not recommended that such food should be eaten). With oxygen absorbers trapping the available oxygen and moisture inside the packet, food looks new as it is just packed and tastes better.

Even vitamins in the food can get oxidized.

Nutrient oxidation will bring about a few issues, yet one of the significant worries for any store is a loss in its nutritional values. Food that is newly packed in an oxygen-rich environment would lose dietary benefits somewhat because oxygen causes the degradation of vitamins. Among all the vitamins, Vitamin E, A, and C are the ones that can react easily with oxygen. Hence, it is clear that foods fortified with these vitamins would benefit from using oxygen absorbers inside the package as it helps create an environment devoid of oxygen, leaving Nitrogen in plenty, which enhances the shelf life of the food product.

how to use oxygen absorbers

Add Oxygen Absorber

You must wonder how a small packet of oxygen absorbers can absorb all the oxygen in the package? Then, Read On to Know More! The key to the average oxygen retaining package (like these) is a chemical reaction between sodium/iron in the packet and the dampness in the surrounding air. Plastic packets permit the entry of moisture. Sodium and humidity allow iron in the packet to get rusted, leading to the formation of iron oxide. As soon as this oxidation happens, the packet quickly empties the trapped oxygen of the container. However, a more viable or bigger packet is intended for containing metal rust. Hence oxygen gets removed without affecting the food. Other major air components such as Argon and Nitrogen are left with different elements present in trace amounts. These components generally don't react with food, further leading to enhancement in the shelf life.


Additional methods for improving the viability of oxygen absorbers from the outset guarantee that you are utilizing a safeguard appraised appropriately for the size of the compartment, just like the sort of food that you will use. Foods in powdered form leave very little space inside the container for concealing oxygen and hence, utilize small packets of oxygen absorber. As a general rule, metal and glass containers are much more effective for storing food for longer durations, whereas some plastics are permeable to the entry of oxygen.


Now, it has changed to a solid structure, which signifies that it has utilized its maximum potential. Now that we know why it should be used and where it should be used, we must understand how it should be used, and the most important aspect is to limit the exposure of oxygen absorbers to the surrounding air before adding it to the container, as it starts functioning the moment it comes in contact with the air and becomes less effective as an oxygen absorber. Remember to replace the packets with fresh packets when it starts to feel as opposed to their powdered form when added to the container. These little scavengers help keep your food fresh and nutritious while stockpiled in storage areas or supermarkets.

 Oxygen Absorber Packets for Long Term Food Storage

Oxygen absorber little packages are packed with iron powder. The iron absorbs 99% of the oxygen that is available inside the sealed environment. Other atmospheric gases are inert and don't cause oxidation of the food.

Oxygen absorber sachets start absorbing oxygen as soon as they are taken out from the sealed container leading to the formation of iron oxide as a result of oxidation. The right quantity of oxygen absorbers sachets effectively brings the oxygen level down to 0.01% or less.

Why Should We Use Oxygen Absorbers?

If you are looking for something that keeps the food dehydrated and enhances its shelf life, then use oxygen absorbers as they effectively bring down the oxygen level to 0.01% inside the sealed environment. It can also be used for dried foods to enhance their shelf life further. Also, it helps you preserve your food without causing any reaction or adding additives, which means it doesn't compromise the nutritional value of the food.

These oxygen absorbers effectively absorb the moisture, which is as much as 3 times its weight, and protect the food products against the adverse changes that may occur in the presence of oxygen and moisture, such as the growth of mold, mildew, degradation of colour, and quality as moisture acts as a catalyst for speeding the oxidative degradation which further leads to worsening of the factors contributing to the degradation.

Now that we know it's easy to use, one should always be careful. It starts absorbing oxygen as soon as it comes into contact with the surrounding air; hence, it must be added immediately to the container prepared with food.

How To Use Oxygen Absorbers?

The type of food and the container will help you determine how many packets of oxygen absorber you'll require based on the content of oxygen that can be effectively brought down to 0.01% or less.

Oxygen absorbers contain Iron Powder, Bentonite, Activated Charcoal, Sodium Chloride, Resin, and Water. These components make a perfect adsorbing base that adsorbs the oxygen and moisture that somehow enters while packaging the product. Oxysorb for food storage is effective against deterioration caused by oxygen while in storage.

When oxygen absorbers get solidified, that's the sign that all the iron powder has been oxidized, and it's time to replace the used packets with the new packets of oxygen absorbers. Oxygen Absorber is available in 50cc, 100cc, 300cc, 500cc, 1000cc, and 2000cc packets. Also, these packets can be used in combination to cover the volume. Once you have determined the number of packets, food, and the type of container, you can begin with the steps below.


Step 1:  Prepare your container and food.

Containers that you will use should be clean and dry before adding the food, and they should be closed immediately.

Step 2: Keep the Oxygen Absorbers inside a sealed container

Oxygen absorbers start absorbing oxygen as soon as it comes in contact with air, so keep them packed inside a mason jar and add them immediately when your container is prepared and close the lid.

Step 3: Seal the container and label it with the date for your reference

Containers For Oxygen Absorbers

When choosing containers compatible with oxygen absorbers, mylar bags, mason jars, and large plastic containers are the best-recommended containers. Generally, a mason jar is preferred to preserve a small amount of food, and a mylar bag/large plastic container is used to store a large amount of food.

One Should Be Careful Of The Following Points While Using Oxygen Absorbers:

Oxygen absorbers are often misunderstood for silica gel made of silicon dioxide. It is one of the widely used desiccants in many products like shoes, leather purses, electronics, pharmaceuticals etc. It helps in preserving the goods against the adverse effects of moisture.

Ensure the oxygen absorber packets are least exposed to the surrounding air before adding to the container because it starts functioning soon after coming in contact with the air.

Replace the old packets with new oxysorb packets when they become solidified instead of a powdered form when added to the container.

What are Oxygen Absorbers/Scavengers?

Oxygen absorbers have wide usage in the food and beverage industry where it is employed to remove excess oxygen from food packages. The presence of oxygen in packages/containers holding food items does not bode well for the latter. This is due to the following reasons:

1) When exposed to oxygen over a period of time, food products turn stale and therefore, inedible.

2) Oxygen provides the perfect environment for the growth of micro-organisms like fungi, bacteria, which are harmful for the packed items.

It is thus to remove an excess amount of oxygen from closed spaces that companies make wide use of oxygen absorbers. The oxygen absorber or scavenger (as it is sometimes known as) will suck in all the extra oxygen present in the atmosphere thus leaving behind nitrogen, which is conducive for the long shelf life of products.

The functioning of the oxygen absorber is explained as follows: The oxygen absorber sachet contains iron particles, which will react with the absorbed oxygen to form iron oxide. Ideally, one needs at least 65% relative humidity in the atmosphere for the oxidation process to begin. As the oxidation process continues, all the oxygen in the packages will be removed and come down to below 0.01%. When all the oxygen has been taken in, the sachet gets “saturated” and will not be able to take in any more oxygen.

Iron is mostly used in oxygen scavengers because of many reasons. Firstly, it does not react with the packed food items. Secondly, it does not release odor like sulfur or aluminum compounds.

The Right Way of Using Oxygen Absorbers

Now that one has decided to use oxygen absorbers, they must also know the proper way of using the absorbent. First, one must keep all the jars/vacuum sealing bags in the table. Next, with the help of gloves place all the food items, which are to be preserved, in the jars and vacuum bags. The usage of gloves is recommended as it protects the food items against the ill-effects of moisture and oils.

After all the food items are placed in the containers, open the bag of absorbers and place one as fast as possible into the jars. The jar lids must be kept nearby so that as soon as the oxygen absorbers are placed one can seal the jars/containers. This is important as it will prevent any outside air from getting inside the container. Please note: Keep the unused oxygen absorber sachets sealed for further use.

If you have babies at home, you must be keeping baby food to feed them from time to time. It is very important that baby food is kept fresh and unspoiled at all times because you don’t know when the food will be required. If it gets spoilt then it will cause great discomfort to the baby and parents as the former will be hungry for a long period of time. If one is at home there is some relief because you can feed the baby something else. The difficulty of not having fresh baby food occurs when one is traveling and is only carrying baby food. This is when the role of oxygen absorbers becomes essential as just a few sachets of oxygen absorbers would have kept the baby food fresh for hours.

What Is Oxygen Absorbers?

Oxygen Absorbers are mainly used to maintain optimum oxygen levels in the atmosphere. They are mostly used while storing and transporting things like food items, pharmaceuticals, drugs among others. Oxygen absorbers are highly needed for storing food like bakery items, dairy products, and baby food. Baby puree storage using Oxygen absorbers is always a good idea. The oxygen absorbers ensure that only the safest baby food is made available to your baby.

Oxygen absorbers are made of iron powder or ferrous oxide, which will absorb all the oxygen from the surroundings. When oxygen absorbers are placed alongside baby food, they will absorb the oxygen, thus leaving behind nitrogen, which is conducive to the long life of baby food. The main constituent of oxygen absorbers is iron, which will react with the incoming oxygen to form a ferrous oxide. This process will continue till all the oxygen has been absorbed and then the oxygen absorber becomes “saturated”.

Oxygen absorbers usually come in small sachets and are generally sold in food-safe, BPA-free pouches. These pouches are perfectly okay for baby food as they are non-toxic and will not react with the food items stored inside.

Safest Baby Food With Oxygen Absorbers

While some people recommend freezing baby food to keep it fresh and usable, that may not be a good idea in the long run. Keeping baby food in the freezer helps for short periods of time and if it needs to be given immediately to the infant. However, if it needs to be kept unspoiled for longer hours then the safest option is to place oxygen absorbers alongside the baby food. Then you can have the safest baby food for the longest time possible.

The biggest advantage of using oxygen absorbers is that it always follows baby food storage guidelines and in the process keeps parents assured and tension-free. Baby food storage guidelines are of utmost importance as they ensure the baby food is stored in the best manner possible. This goes a long way in providing top-quality baby food to infants, which aids their growth in the proper manner.

If one is opting for oxygen absorbers for baby food storage, the former goes a long way in keeping mold and aerobic pathogens away from baby food. If the baby food is freshly prepared and there is the growth of mold and aerobic organisms in it, it will become stale and thus cannot be given to the baby. So for the health of the baby, one must always consider baby food storage using oxygen absorbers.

Placing baby food items in storage alongside oxygen absorber sachets will also ensure that no pests will harm the baby food. Oxygen absorbers, as one knows, removes all the oxygen from the atmosphere. This oxygen-less environment is not beneficial for the growth of eggs and larva so the pests are not able to grow. Thus in this manner, oxygen absorbers keep baby food intact for longer periods of time.

Not many people are aware of it, but oxygen absorbers for baby food storage go a long way in keeping moisture away from the latter. The oxidation process changes the iron oxide into rust. When this process is going on then it also absorbs the moisture, sodium and activated carbon or charcoal. All these factors are responsible for the growth of micro-organisms. Once they are removed, the baby food will be fresh for days together.

One of the most common methods used in the food processing industry is the dehydration of the food. The entire process of dehydration works in a certain way that moisture is completely taken out of the food source in order to extend the shelf life of the food and infesting it with microorganisms.

Known to be one of the most popular and old methods which were used in the preservation of food, the dehydration business has been going on for a very long time. Starting from North American Indians who used dehydration for sun-drying their meat products to the Chinese dried eggs, now the entire industry of food processing has dedicated a major share of their resources for the dehydration of foods and different beverages.

Mostly meat products and dairy products go through the entire process of dehydration to ensure that their shelf life is extended. For example, beef jerky is one of the most common items that are created in the food processing industry with the help of dehydration. Several methods are used in order to increase the beef jerky shelf life.

This article will discuss briefly the creation and storage of beef jerky using oxygen absorber bulk. This post will let you know how long does dehydrated beef jerky lasts and how to dehydrate meat for long-term storage.

The oxygen absorbers bulk is the sachets that are used by many food processing units in order to keep air, oxygen, and moisture away from the beef jerky. But do oxygen absorbers absorb moisture? Well, read on ahead to find out more.

Importing And Exporting Dehydrated Meat Products

Ever since the existence of dehydration processes in the food and beverage industry, people have been fascinated by the creation of beef jerky. To extract the entire moisture out of the meat to make it last for a long time is something that can help in extending the shelf life of the meat. This is one of the main reasons why meat processing factories are all focusing on the production and import/export of beef jerky and other dehydrated meat products.

However, doing that isn’t that simple. There are certain issues that can crop up when it comes to the production of beef jerky and the extension of its shelf life. For example, one of the most common issues for the shelf life of beef jerky would have to be moisture. You see, after the completion of the dehydration processes, it is imperative that the beef jerky is stored in a sealed environment so that it stays away from moisture. After all, it is the lack of moisture that allows the microorganisms to grow and create beef jerky. Very often, it happens that moisture might find its way back to the beef jerky and as a result, it might not be suitable for import/export.

Does Beef Jerky Go Bad?

oxygen absorbers

The answer to that question would have to be yes. The question here is whether the beef jerky is home-made or store-bought. The beef jerky that is bought from the stores will be able to last for a period of about 2 years if the container remains unopened. However, home-made beef jerky doesn’t last that long.

The factors that are responsible for the lasting of the beef jerky are mentioned below.

Complete Lack of The Fat

Since beef jerky tends to be a lean and thin cut piece of meat, there is literally no fat amount in it. So, the beef jerky lasts for a longer duration of time.

No Moisture

One of the main factors for bacterial growth is moisture. Beef jerky is created in an environment with no moisture and hence is able to extend the shelf life of the product.


Beef jerky has got a salty taste, to begin with. This is because it is treated and cured with the help of salt. The process of salt curing helps in preserving the beef jerky so that it can last for a very long time.

How Long Will The Beef Jerky Last?

oxygen absorbers

One of the main questions revolving around the storage of beef jerky is that how long does dried meat last? Well, the contamination, storage factors, moisture, ingredients, and the time period are all factors that decide the shelf life of beef jerky.

The product packaging has the expiration date so that you can check it out before you buy the beef jerky.

Now how to tell if beef jerky has gone bad? Well, there are some methods that you can use for checking the spoilage if the package doesn’t mention the expiry date clearly.

Checking for signs of moisture is one of the ways to see if the beef jerky has gone bad. If there is the formation of water droplets, then there are chances that the beef jerky has gone bad. Also, you can check by pressing every single piece to see if there is any softness. If there is, then the beef jerky is probably bad and it is a sign of bacterial growth. Also, unnatural odors are a great sign for checking the spoilage too.

How To Store Beef Jerky For Peak Flavor And Freshness

It is essential to know how to store beef jerky if you want to extend the shelf life of the product. There are different beef jerky packaging requirements that need to be followed for proper storage of the product. Here are some of the steps that you need to follow.

Limit The Air Exposure

Retaining the same quality of the beef jerky can be done by sealing it in an airtight container. Most people would recommend the use of oxygen absorber sachets which can help in preserving by not allowing oxygen to enter the beef jerky.

Eliminate The Sources of Moisture

Water in the beef jerky will make it go bad very soon. You need to make sure that it stays dry for the retaining of the shelf life. Using oxygen absorbers, the moisture content can also be eliminated from the product.

Control The Temperature

Most of the time, over sweating the beef jerky spoils the quality of the product. So, storing your beef jerky in a particularly cool temperature will be a good idea. Try freezing the jerky before you store it in the 50cc oxygen absorbers.

Maximizing Beef Jerky’s Shelf Life

oxygen absorbers

Here are some tips and tricks that you can use in order to retain and maximize the shelf life of your beef jerky.

Allow the beef jerky to cool down for some time before you store it in the oxygen absorbers 300cc

Storing the beef jerky in a particular paper bag will allow it to remove all traces of moisture from the product.

Using oxygen absorbers can also be a great way of maximizing the shelf life of the beef jerky. With these absorbers, oxygen can be completely eliminated so that the bacterial growth can be stopped in the beef jerky. There are many sizes available for oxygen absorbers. The most common ones are the 500cc oxygen absorbers and the 2000cc oxygen absorbers. It is important to decide what size oxygen absorber to use depending on the beef jerky that you have.

Vacuum packaging is another way of extracting the oxygen in order to prevent the beef jerky spoilage.



The storage and care of beef jerky are really important in order to maximize the beef jerky shelf life. Although all these methods are pretty common in the food processing units, the use of oxygen absorbers is one that is used most of the time.

 Oxygen Absorber Packets for Long Term Food Storage

Oxygen Absorbers are small packets that contain an iron powder. These packets are made of a material that allows oxygen to enter but does not allow the iron powder to leak out. When an oxygen absorber packet is removed from its protective packaging, the Oxygen molecules & moisture in the surrounding atmosphere begins to permeate into the iron particles inside of the absorber packets. Available moisture activates the iron, and it oxidizes to form iron oxide. Typically, there must be at least 45% relative humidity in the surrounding atmosphere before the rusting process can begin. To assist in the process of oxidation, sodium is added to the mixture. Sodium acts as a catalyst, or activator, causing the iron powder to be able to oxidize even with relatively low humidity.

As oxygen is consumed to form iron oxide the level of oxygen in the surrounding atmosphere is reduced. Absorber technology of this type may reduce the oxygen level in the surrounding atmosphere to below 0.01%. Complete oxidation of 1 g of iron can remove 300 cm3 of oxygen in standard conditions. Iron is the most useful as it does not cause odor like sulfur compounds or passivate like aluminum compounds. The moisture requirement of iron-based scavengers makes them ineffective in moisture sensitive applications.

Hence to resolve this issue, Sorbead India product “oxygen-absorber” has a slight proportion of water already present in the sachet hence it instantly activates upon exposure even under relative humidity less than 45%. The Oxygen Absorbers for Pharmaceuticals are highly recommended to oxygen-sensitive drugs & found to use for all those sensitive drugs which are amorphous & spray dried API. They are available in various sizes and absorption capacity, making it suitable for both bottle and bulk packing. The paper and the ink used to print on the Oxygen Absorbers Packets are all food-grade hence it can be used in direct contact with the drugs. Even during accidental consumption, there is no damage to the human body.

 Oxygen Absorber Packets for Long Term Food Storage

Many foods are very sensitive to oxygen, which is responsible for the deterioration of many products either directly or indirectly. In fact, in many cases, food deterioration is caused by oxidation reactions or by the presence of spoilage aerobic microorganisms. Therefore, in order to preserve these products, oxygen is often excluded. Oxygen presence in food packages is mainly due to failures in the packaging process, such as the mixture of gases containing oxygen residues, or inefficient vacuum. Vacuum packaging has been widely used to eliminate oxygen in the package prior to sealing. However, the oxygen that permeates from the outside environment into the package through the packaging material cannot be removed by this method.

The use of oxygen scavenging packaging materials means that oxygen dissolved in the food, or present initially in the headspace, can potentially be reduced to levels much lower than those achievable.

Oxygen scavengers Used in Meat Packaging to control color in red meat packages. When the pigment for red meat (hemoglobin) is exposed to oxygen, the meat appears as a bright red color, which is associated with freshness and overall acceptability. However, when meat is exposed to too much oxygen over time, the pigment converts to hemoglobin, which appears as a brown color and is not visually acceptable to consumers. Oxygen can turn fats rancid, cause flavor deterioration, create color changes, encourage mold and aerobic bacteria growth, and deplete nutritional values.

The Uses of Oxygen Absorber designed for the specific package can retain freshness and extend product shelf life without the use of artificial additives.

What is Oxygen Absorbers?

The main use of Oxygen Absorbers is to protect against the decay products, mainly food items. Oxygen Absorbers are small sachets, which are placed alongside the food products to ensure that they do not get spoilt. They absorb the oxygen present in the closed space and leave behind a nitrogen-filled environment, which is useful in extending the shelf life of the product. Oxygen Absorbers usually contain iron powder and sodium chloride, which reacts with the adsorbed oxygen to create iron oxide. When all the oxygen is absorbed, the Oxygen Absorber sachet becomes ‘saturated’ and will stop the intake of oxygen.

Main Benefits of Using Oxygen Absorbers

  • Effectively brings down the oxygen levels– The main use of oxygen absorbers for food is for reducing the levels of oxygen present in packages so that the product can enjoy an extended shelf life. Oxygen Absorbers carry out this function properly as they absorb nearly 90% of the oxygen present in the closed space. Experts are of the opinion that amongst all the technology available today, oxygen absorbers are the best in maintaining optimum oxygen levels.
  • Cost-Effective: Another major advantage of using Oxygen Absorbers is that it is highly inexpensive and thus proves cost-effective while transporting food products to faraway places. Cost is an important factor to consider during long-distance transportation and the use of less expensive Oxygen Absorbers is always an advantage.
  • Readily Available: Another major advantage of Oxygen Absorbers is that it is easily available in the market and one does not have to search everywhere as to where to purchase it from.
  • Non-poisonous ingredients: Oxygen Absorbers are okay to keep with food products as they are not poisonous and only contain iron oxide. Some people felt that when placed alongside food items, sometimes the Oxygen Absorber may react with the former and spoil them.
  • Easily Disposable: Last but not least, the main advantage of Oxygen Absorber sachets is that they are environment-friendly and can be disposed of using the regular disposal methods. They do not require any special method for disposal.

Going through these benefits one understands why so many people opt for Oxygen Absorbers during storing and transportation of food products

How Fungus Affects Food Products

It is a known fact that food products have a limited shelf life. If they are exposed to air or vapor, then they will get damaged in no time. Food products are easily vulnerable to spoilage organisms like mold, fungus and different kinds of bacteria like mesophiles, psychrotrophic, thermophiles, and psychrophiles. The presence of this kind of fungus and bacterial organisms spells bad news for all kinds of food products, beverages, and dairy items.

The damages caused by fungus and bacteria are many. These spoilage organisms work by breaking down the chlorophyll present in plants and the iron elements in protein. This will not only make the food product inedible but also cut down its shelf life. When the organic enzymes are separated, then it leaves behind traces of ammonia, amines, sulfides and organic acid buildups. These react in a negative manner with food products. It will lead to the food items changing colors, turning rancid and becoming greasy. The end result of exposure to fungus and bacteria is that the food will turn stale and be unfit for consumption. If this happens while the food items are being transported from one place to another, then it will lead to heavy financial losses for companies.

Role of Oxygen Absorbers in Food Storage

Spoilage organisms like fungus need oxygen to grow and survive. They grow and reproduce faster in an oxygen-rich atmosphere. So the first thing one must do in order to prevent the growth of spoilage organisms is to remove all traces of oxygen from the packed spaces. When deprived of oxygen, the spoilage organisms cannot thrive and thus one can prevent the food items from getting spoilt.

While there are many other ways to create a vacuum in closed spaces, the best method is to make use of oxygen absorber sachets. These sachets contain ferrous oxide, which reacts with the oxygen present in the packed spaces to turn into rust. This process usually continues till all the oxygen has been absorbed and the oxygen absorber becomes “saturated”. Once all the oxygen has been absorbed, all that remains behind in the closed spaces is nitrogen, which is favorable for prolonging the shelf life of the product as well as keeping spoilage organisms at bay.

Oxygen Absorbers and their Benefits

We hear the term oxygen absorbers everywhere but do we actually know what they are and what they are used for? Oxygen Absorbers are small packets containing iron powder, which are placed along side products like electronic and leather items, pharmaceuticals and most importantly, food items, which become stale after some time. This happens due to the presence of oxygen in the packages containing these products. It will react with the food items/pharmaceuticals to turn them rancid and change their physical/chemical combinations respectively. This is why companies make use of oxygen absorbers to take in all the excess oxygen present in closed spaces so that the packed products remain intact. If the goods are being transported to long destinations, then oxygen absorbers are a “must” as the goods will packed for days together and therefore their chances of getting spoilt are higher.

How Oxygen Absorbers Function

The working of the Oxygen Absorber is explained as follows- the iron powder present in the Oxygen Absorber sachet will absorb almost all the oxygen present in the closed environment. This will preserve the shelf life of the product and keep it fresh for longer periods. After all the oxygen is absorbed, certain atmospheric gases will be left behind in the packages. They are, however, inert and do not lead to spoilage of items. Oxygen Absorbers for food is important as these items are perishable and therefore need extra attention.

How Oxygen Absorbers Preserve Sweets

Like all other food items, sweets and confectioneries also have a limited shelf life. If left unattended, they can get spoilt and therefore inedible after a period of time. If this happens on a big scale, then the losses will be immense. This is the main reason why the food and beverage industry need oxygen absorbers in large numbers. When sweets are packed in large quantities, one should also place a sufficient number of oxygen absorbers as well because it will absorb all the oxygen in the packages and ensure that the sweets remain fresh for longer periods. This is ideal for situations like when the sweets have to be transported to far away places.

In the packages, the oxygen absorbers work to take in all the oxygen from the atmosphere. This leaves behind nitrogen, which is conducive for the long shelf life of the packed sweets. Periodical checking must be done to see if the oxygen absorbers are saturated or not. If they are saturated, then they must be replaced with new ones.

 Oxygen Absorber Packets for Long Term Food Storage

Oxygen is known to be one of the main sources of bringing along with it unwanted moisture and sometimes other toxic gases mixed with it. This causes most packaged foods and other sensitive equipment to get spoiled in double-quick time. Especially, in packaged foods, the presence of oxygen can lead to severe contamination and mold growth along with rancidity and in the loss of nutritive value of the foods that are packed with oxygen in them.

Oxygen Absorbers

A suitable solution was needed to protect and extend the shelf life of most packaged foods. This saw the emergence of oxygen-absorbing strips and packets that contained specific substances that have a strong affinity for water vapor. Many of these strips can protect the foods from as much as 99.9 % of moisture and thereby be ensuring their longevity. Additionally, they preserve all the qualities of the original food before it was packed.

The use of oxygen absorbing strips has almost become a necessity when foods have to be preserved to be used at a later time. Apart from keeping oxygen out, they prevent the growth of aerobic pathogens and other microorganisms that thrive in oxygenated places where food products are stored. They also reduce the need for any additives in order to retain the originality of the food.

There is also sensitive equipment that performs critical operations that need protection from the harmful effects of moisture that comes with the oxygen. In many cases, they can be easily corroded or develop rust, which can be severely poisonous to humans. The use of Oxygen Absorbing Strips has becomes almost mandatory when these items are packed or stored. They are known to absorb even the smallest amounts of oxygen that may permeate through the packaging material.

Most of the oxygen-absorbing materials are packed in food grade packets and come with a warning printed on them to prevent their consumption.

Research Reports

According to several research results that have been conducted on the efficacy and safety of these Oxygen Absorbers, it has been concluded that the shelf life of food products can be extended for considerable periods of time. In the case of meats, they can be stored up to a month, whereas, there are other foods that remain the same until the time their packing is opened and consumed. They are also known to prevent the formation of volatile compounds that may be formed in the case of foods that have a high content of fat.

 Oxygen Absorber Packets for Long Term Food Storage

Oxygen is the fundamental requirement of every living being. But it is also the main reason for the spoiling of food and rusting of metals. This can mainly pose a threat in packaged food. And you cannot use any chemical to remove the oxygen because those chemicals will also react with the food products, making them toxic and unfit to consume. The best solution to avoid food spoilage from oxygen is by using absorbers. Oxygen absorbers are also known as oxygen scavengers. Scavengers are substances that remove unwanted products when added to a particular package. FDA standard approved food grade and pharma grade o-busters to help protect the packed food items. Due to their oxygen killing characteristics, they are also called o-busters.

Oxygen scavengers are basically small porous sachets containing a mixture of powdered irons and sodium chloride. Iron is the active ingredient responsible for the process of oxidation. The iron in the packet absorbs 99.9% of the oxygen in the container and begins to rust. It gives out nitrogen which is helpful in keeping insects and pests at bay. O² scavengers react rapidly with oxygen, passivate steel surfaces, have volatility and can be safely handled. Because they do not discharge any harmful gases or toxic elements, it is safe to use them in the food and pharmaceutical industries. Oxygen scavengers are designed to remove or decrease oxygen levels from inside packaged products, especially vacuum packing. They help to prevent the growth of fungus mold, mildew, and bacteria. In this way, they increase the shelf life of a product. Usually, each package is about 20cc to 3000cc o-busters in size. Sometimes, even zeolite and water are also used in absorbers. Water-based oxygen scavengers are generally used in seawater injection and production separation systems as a tool to prevent oxygen-induced corrosion.

The oxygen scavengers create oxygen depriving environment to help keep the packed food fresh. Hence they are used in packing of coffee and nuts, spices, seasoned foods, cheeses, and dairy products, fruits and some vegetables, berries, and sauces, snacks, cured meat, flour, and grain items, Bread, cookies, cakes, pastries, medical diagnostic kits and devices, and pharmaceutical products. As the oxygen scavengers are approved by the FDA, they are safe to be used in food packing and pharmaceutical packing.

 Oxygen Absorber Packets for Long Term Food Storage

The key use of oxygen absorber is to protect the shelf life of the food. In the case of packaged food, it stays in the retailer shop or malls for many days which may impact the quality of the food. But oxygen absorbers protect the taste and quality of the food along with the color. It also prevents the growth of oxygen-aerobic microorganisms like fungi etc. Plastic foods are not able to keep oxygen away from the food unlike metal or glass container. Oxygen, on the other hand, helps microorganisms to grow which causes damage to the product. But these oxygen absorbers absorb the oxygen from the packet.

Different kinds of oxygen absorbers are presently available in the market and the application depends on the specific needs. The components of oxygen absorber vary according to the purpose for which it is being used. Basically there are three ingredients iron powder, sodium, and activated carbon. Iron is the primary ingredient and sodium acts as an activator and causes the iron particles to rust and effectively reduce the level of oxygen from the surrounding atmosphere. An oxygen absorber is not harmful to the foods, it doesn’t generate any other gas and doesn’t distort the original smell and taste of the product.

Over the last almost 15 years oxygen absorbers have brought a revolution for the food package industry. It has made the job much easier and simpler than before. This has increased the life of foods after the storage process. On average these absorbers last for around one year. So, you can expect the taste and color of the food to remain unchanged even after a year's time period. Is it safe to eat this absorber? Well, it may not be a good option for your health. This is why it is often mentioned outside the container that there is oxygen absorber inside which should be discarded upon finding.

Now the concern is how many oxygen absorbers are required? Well, the number varies for different things like the size of the packet of the oxygen absorber, area of the container, type of the food that is being canned and the altitude of the place. But it is proved through various tests that a 500cc packet is enough to fulfill most of the jobs.

 Oxygen Absorber Packets for Long Term Food Storage

In the packing of meat, it is an established fact that the presence of oxygen can create contamination of different kinds in a very short period. This greatly reduces its shelf or storage life. Obviously, the remedy to this problem is to remove the presence of any oxygen while packing meat and its products.

Among the better-known methods of keeping oxygen out is with the use of oxygen absorbing packets. These can also be available in the form of strips or rolls of varying shapes and sizes. Each type of meat packing must have its own unique manner of keeping oxygen out. The presence of oxygen brings along with it moisture, which is another root cause for contaminating the products quickly.

One of the most effective ways of producing quality oxygen absorbers is by combining zeolite and chelated carbon and packing them either in polyester, polyethylene or in Tyvek paper as per the demands of the packaging required. It is important to note that these packing materials remain non-toxic at all times and do not bring about any changes in the meat products packed with them, besides, they have been approved by the USFDA.

Apart from eliminating the presence of oxygen and moisture, these packets also help in securing the contents from other corrosion contributing factors and increase their shelf life considerably without even changing their color or other compositions of their contents.

There are other similar methods that can be used to bring the same desired results. Interestingly, all these are low in cost and can preserve meat products for almost 30 days in their original condition. Consumers can now feel confident that the meat packaged in this way is very safe for consumption.

The Many Benefits of Oxygen-free Packaging

Some of the several benefits of this form of packing meat products are listed here:

  • It enhances the storage or shelf life over extended periods of time.
  • It is a low-cost solution for preserving meat products.
  • The packaged meats can now be transported and distributed freely.
  • This method of oxygen removal is sometimes more effective than the job done by expensive machines.
  • It preserves the quality and the taste along with its visual appearance till it is consumed.

These oxygen packets do not require any activation and provide a low start-up cost.

 Oxygen Absorber Packets for Long Term Food Storage

Oxygen absorbers remain a staple product for the preservation of food to reduce food wastage in developed nations and increased food security in the developing nations.

An oxygen absorber works at the available moisture in the packaged food and the trapped air causes the iron in the absorber to turn to rust, which then reduces the presence of oxygen, this process is called “oxidation.” This transition in oxygen content creates a higher concentration of nitrogen, which is better for the long term shelf life of the packaged food item.

Oxygen absorbers are used with baked goods, nuts, coffee, processed food, seasonings, flour, grains, pharmaceuticals, vitamins, pet foods, dehydrated fruits, vegetables, and meats. They bring down the oxygen level to 0 .01% or less.

Products that are low in moisture and the oils are best preserved with the absorbers. Foods should be below 10% moisture content for storing with absorbers. Storing foods with high moisture content in reduced oxygen packaging may result in botulism poisoning. For other foods like wheat, beans, corn, and peas, the oxygen absorbers will not make a difference as these are not oxygen sensitive.

Oxygen absorbers come in sizes varying from 20cc to 3000cc in individual sachets. (The “cc” stands for cubic centimeters as it relates to the amount of oxygen-absorbing capacity). Hence, the smaller the size of the container or volume of the bag, the lower would be the required capacity of the oxygen absorber.

Advantages of oxygen absorbers sachets:

  • Extend the shelf life of products
  • Prevent oxidation of spice oleoresins present in spices themselves and in seasoned foods
  • Prevent food damage from infestation of insects
  • Inhibit the growth of aerobic pathogens such as molds, mildew, and bacteria.
  • Significantly improve keeping qualities of polyunsaturated fats and oils
  • Delay the discoloration in foods
  • Eliminate the need for additives such as sulfur dioxide, BHA, BHT, sorbates, etc.
  • Foods are not crushed or squeezed
  • Prevent oxidation of vitamins A, C, and E
  • Help retain the fresh-roasted flavor of coffee and nuts

Sorbead India is the global supplier of oxygen absorbers, its Oxygen Absorbers come in sachets and are supplied to a wide range of customers in the Food Industry.

Excellent quality iron is used to make the high-quality oxygen absorbers and iron quality make it an apt oxygen absorber to be used for food products, it is a necessity to use the food grade iron form to get the safe quality of oxygen absorbers for the avoidance of any type of risk to the packed products.
