The presence of oxygen is very harmful for all packaged products, especially nuts. If they are stored in packages for a long time, then they will be affected by oxidative degradation. When nuts come in contact with oxygen then it leads to the oxidation of the Vitamins A, C and E, which are present in the nuts. If the oxygen presence in packages containing nuts is for an extended period of time, then the chances of spoilage pathogens developing is quite high. All kinds of aerobic bacteria and organisms like fungi, molds can grow on the oxygen-rich nuts.
Oxygen absorbers are the one-stop solution for tackling the problem of oxidative degradation in nut packages. Placing an oxygen absorber sachet near the nuts will not only keep the oxygen away, it also helps in enhancing keeping qualities of Polyunsaturated fats and oils. As nuts contain oils, which shorten their shelf life to six months/ one year, using oxygen absorber sachets is a good move.
Most people use oxygen absorbers in combination with gas flushing or vacuum packaging to make sure that almost all oxygen has been removed from the packages containing nuts. This triple protection of oxygen absorbers, gas flushing and vacuum packaging is a foolproof guard against oxygen molecules.
