An oxygen absorber is a small packet of material used to prolong the shelf life of food. They are used in food packaging to prevent food colour change, to stop oils in foods from becoming rancid, and also retard the growth of oxygen-using aerobic microorganisms such as fungi.
Steamed bread, moon cakes, cakes, peanuts, charqui, dehydrated vegetables and so on.
Plan to use your oxygen absorbers within 6 months of purchase as they will lose effectiveness after that time. They will start working within 20 minutes of being exposed to oxygen.
Oxygen absorbers come in a plastic bag. Each absorber packet has a special barrier to prevent it's contents from making contact with your food. If left exposed to air, the oxygen absorbers will be rendered completely useless in as little as 5 hours. Plan ahead and use all of the absorbers or seal the remaining packets in an airtight glass mason jar. The 100CC Oxygen Absorbers work for about 100 #10-sized cans or 25 of the 5 gallon buckets filled with beans, rice, flours, grains or whatever you choose.
The advantages of oxygen satchels versus vacuum packaging are that the food products are not crushed or squeezed, as some products are of high value and are fragile, and its simplicity of use.
