When I plan long term storage of my dehydrated garden. I will extend the drying time to ensure moisture content is as low as I can get it. Fruits and vegs. have different moisture content percentages for storage. I have to look it up each time and I have no way to measure it, dry and brittle vs. leathery and such. After dehydrated I temp store it in ziplocks with reusable desiccant pacs until I have enough to put into 1gal. mylar. Then remove the desiccant and seal up with O2 sorbers as they clash for LTS. I have about 40 or so 1 gal mylar I have done over the years, I have yet to open one so I remain optimistic on my efforts.
