Oxygen scavenger, also known as deoxidizer and oxygen absorber, is an additive that can absorb oxygen and slow the oxidation of food. It is a new product currently being used in food preservation. It is a chemical mixture that reacts easily with free oxygen or dissolved oxygen. It is a mixture of black and gray particles before oxygen absorption. It is brown and agglomerated after oxygen absorption. Like the desiccant, it is sealed in the food packaging bag together with the food. It can remove the oxygen remaining in the bag, prevent the food from discoloration, deterioration and rancidity due to oxidative, and inhibit the growth of mold, aerobic bacteria and food pests.
Oxygen absorber for food storage is packed in a sealed paper bag with a certain degree of air permeability and strength. The package material is made of high-grade 3-layer composite film. In order to ensure the permeability and prevent powder leakage, micro-perforation technology is adopted to punch micro holes on the package. It is printed with food grade ink by a sandwich printing process, safe, high temperature resistant, and non-fading..
