Hapnikuandur

Hapnikuandur, often referred to as an oxygen absorber or oxygen scavenger, is a desiccant product designed to remove oxygen from sealed packaging. It is commonly used in food packaging to extend shelf life and maintain product quality by preventing oxidation. Oxidation can lead to spoilage, discoloration, and the development of off-flavors and odors in many food products.

These absorbers typically contain iron powder, which reacts with oxygen in the presence of moisture and a catalyst (like activated carbon or salt) to form iron oxide, or rust. This process effectively lowers the oxygen level within the package to near zero. Other common ingredients may include cellulose, water, and sodium chloride. The effectiveness of a hapnikuandur is determined by its capacity, which is the amount of oxygen it can absorb.

Hapnikuandur are found in various forms, including sachets and sheets, and are available in different sizes to suit diverse packaging needs. They are crucial for preserving the freshness and integrity of items such as dried foods, baked goods, snacks, pet food, pharmaceuticals, and even electronics. Proper sealing of the package is essential for the hapnikuandur to function effectively, as it needs to create an oxygen-depleted environment. Once the package is opened, the hapnikuandur is exposed to ambient oxygen and its absorbent capacity is rapidly depleted.
