An oxygen absorber The contents of an oxygen absorber from a packet of beef jerky. Oxygen scavengers or oxygen absorbers are added to enclosed packaging to help remove or decrease the level of oxygen in the package. They are used to help maintain product safety and extend shelf life. [1] There are many types of oxygen absorbers available to ...
While packaging waste is a concern, the main priority for vendors is to minimize food waste caused by spoilage. [11] Active packaging antibacterial indicator absorbent pads that inhibit bacterial growth and visually signal meat deterioration are being explored through the use of nanofibers and silver nanoparticles. [12] [13] [14] [15]
Oxygen scavengers or oxygen absorbers help remove oxygen from a closed package. Oxygen causes acceleration of product degradation and oxidation of e.g. vitamins and fats by stimulating microbial activity. [7] As a result, poor taste, bad odor, discoloration and nutrient degradation may be the consequences.
[1] [2] The need for this technology for food arises from the short shelf life of food products such as meat, fish, poultry, and dairy in the presence of oxygen. In food, oxygen is readily available for lipid oxidation reactions. Oxygen also helps maintain high respiration rates of fresh produce, which contribute to shortened shelf life. [3]
Testing modified atmosphere in a plastic bag of carrots. Food packaging is a packaging system specifically designed for food and represents one of the most important aspects among the processes involved in the food industry, as it provides protection from chemical, biological and physical alterations.

Methods of oxygen storage for subsequent use span many approaches, including high pressures in oxygen tanks, cryogenics, oxygen-rich compounds and reaction mixtures, and chemical compounds that reversibly release oxygen upon heating or pressure change. O 2 is the second most important industrial gas.
