Oxygen Absorber Packets for Long Term Food Storage

How Does Oxygen Absorbers Work with Food Product ?

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.

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.
