Oxygen absorber is a small packet of material used to prolong the shelf life of food.
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. 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.
Preparation:
Oxygen absorbers perform their action through a chemical reaction. They contain iron powder which reacts with the oxygen in the air causing the iron powder to rust. When all the iron powder has oxidized, the oxygen absorbers are "loaded" and the absorbing action stops. Remove the oxygen from an active absorber and the chemical reaction stops. Put them back in the air and the reaction starts again until the iron is gone.
Application:
Steamed bread, moon cakes, cakes, peanuts, charqui, dehydrated vegetables and so on. When used with proper packaging and sealing, the oxygen in the packaging is greatly reduced. Our absorbers bring the oxygen level down reliably to .01% or less.
Benefits:
Significantly improves keeping qualities of polyunsaturated fats and oils
Helps retain fresh-roasted flavor of coffee and nuts
Prevents oxidation of spice oleoresins present in spices themselves and in seasoned foods
Prevents oxidation of vitamins A, C and E
Extends life of pharmaceuticals
Inhibits mold in natural cheeses and other fermented dairy products
Delays non-enzymatic browning of fruits and some vegetables
Inhibits oxidation and condensation of red pigment of most berries and sauces
