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 ...
Food packagers take extra care with some types of active packaging. For example, when the oxygen atmosphere in a package is reduced for extending shelf life, controls for anaerobic bacteria need to be considered. Also when a controlled atmosphere reduces the appearance of food degradation, consumers need to retain a means of determining whether ...
When oxidation is the primary concern, packaging with a low oxygen transmission rate and the use of oxygen absorbers can help extend the shelf life. Produce and other products with respiration often require packaging with controlled barrier properties. The use of a modified atmosphere in the package can extend the shelf life for some products.
Keeping the contents clean, fresh, and safe for the intended shelf life is a primary function. Modified atmospheres or controlled atmospheres are also maintained in some food packages. Some packages contain desiccants, oxygen absorbers, or ethylene absorbers to help extend shelf life.
Oxygen also helps maintain high respiration rates of fresh produce, which contribute to shortened shelf life. [3] From a microbiological aspect, oxygen encourages the growth of aerobic spoilage microorganisms. [2] Therefore, the reduction of oxygen and its replacement with other gases can reduce or delay oxidation reactions and microbiological ...
The best way to store vitamins for optimal shelf-life. Elements like heat, humidity, light, and air are the “main enemies of vitamin freshness,” says Blatner. “Keep them cool, dry, and out ...
