An Oxygen Absorber is a small packet used to extend the shelf life of food and other products by removing oxygen from sealed containers. It helps prevent the growth of bacteria, mold, and yeast, which can spoil food. Commonly used in packaging for dried foods, such as grains, spices, and jerky, oxygen absorbers help preserve freshness and maintain flavor. They are also valuable for preventing oxidation in non-food items, like electronics and pharmaceuticals. By reducing oxygen levels, oxygen absorbers effectively maintain product quality, enhance safety, and prolong the shelf life of various goods.
