Oxygen-Reducing Technology for Improved Shelf Life, Food Safety
Clariant Corp., Charlotte, N.C., answered U.S. consumer demand for improved food safety and quality with Oxy-Guard, an oxygen-reducing technology that helps prevent the growth of mold, fungus and bacteria in dairy products, frozen meals and beverages.
Oxygen is the primary cause of food degradation, affecting flavor, color, smell and texture. It can also deteriorate food’s vitamin and nutritional value. Oxy-Guard packaging inserts contain a combination of salt and iron powder, that when combined, can maintain 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.
Plus, Oxy-Guard technology is said to extend product shelf life from one week to several months compared to packaged food that does not utilize an oxygen scavenger.
