Each Bag contains 20 - 300cc oxygen absorbers. 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. These Absorbers are perfect when combined with one gallon (10"x14") Mylar Bags. The benefits of using oxygen absorbers are as follows: * 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 saucesThe oxygen absorbers come in a clear Mylar bag that can be re-closed with a hot iron to save any unused absorbers still in the bag.Included with these Absorbers is an oxygen indicator pill that will turn from pink to dark blue in the presence of oxygen. Pill will be PINK when you receive your order.
