How Oxygen Absorbers Can Help Extend Shelf Life of Food
Oxygen absorbers eliminate oxygen from a sealed environment, creating a nitrogen-filled atmosphere for the long-term storage of food. By reducing the oxygen level within the packaging, they safeguard dry foods from insect damage and preserve the quality of the product. Oxygen absorbers are typically employed when dry foods are in airtight containers.
Oxygen absorbers can help prevent spoilage and foodborne illnesses, making oxygen absorbers an essential tool for food storage and preservation of nutritional value. They inhibit the growth of aerobic pathogens and spoilage organisms, including moulds, and eliminate the need for additives like BHA, BHT, sulphur dioxide, sorbates, benzoates, Etc.
The oxygen absorbers function through a chemical reaction. They contain iron powder, which reacts with the oxygen in the air, causing the iron powder to rust. Once all the iron powder has oxidized, the oxygen absorber becomes "loaded," and the absorption process stops. The chemical reaction ceases once the active absorber depletes the oxygen. The response restarts if placed in oxygenated air and stops once the iron oxidizes.
