Some dehydrated food supplies have packages of anti oxygen chemicals. Sometimes you see things like that in medicine bottles. They would have the vacuum bags and pumps and stuff and you could probably get lots of free information on how to store food. USDA has lots of information on preparation of food. They publish recipes and directions on canning foods also. I have a 1977 pamphlet on building your own food dryer and how to dry foods. I suspect you could find an digital book online.

Thanks. We purchased some oxygen absorbers to practice with, and we have a vacuum packer. Our ‘prepping’ is small-scale and so far limited to canned supplies, first aid, batteries, water, alternative cooking methods and paper products. But the pets are one of the things I worry about, in case of disruption of supply for some reason.

In a pinch you can always use Hand Warmers in food grade buckets with Gama Seal Lids. I believe you can find cheaper buckets and lids at US Plastics online. The hand warmers work by Iron Oxidation, or oxygen absorption. Hope these suggestions help.
