They are used to help maintain product safety and extend shelf life. [1] There are many types of oxygen absorbers available to cover a wide array of applications. [2] [3]
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 Vika oxygen generating system, used on Mir and later the International Space Station under the NASA designation Solid Fuel Oxygen Generator (SFOG) is based on lithium perchlorate, which releases about 60% of its weight in oxygen. Of all the perchlorates, lithium perchlorate has both the highest oxygen to weight and oxygen to volume ratio ...
