Clariant Oxy-Guard oxygen scavenger packets help prevent the growth of mold, fungus and bacteria in pre-packaged foods.  The packets contain a combination of salt and iron powder that maintains oxygen levels at less than 0.01% inside sealed packages. As the salt absorbs moisture from the packaging, the iron begins to oxidize, initiating the oxygen absorption process. The oxygen scavengers can be used to preserve baked goods, nuts, dried grains, pasta, processed and dried meats, coffee, tea, chocolates, confectionery, dairy products, powdered proteins and beverages, frozen meals, pet foods and other products.
