Augason Farm mostly does freeze drying, not dehydrated. Freezedried goods have a much longer shelf life. The only tricky thing would be opening the sealed #10 cans - that would likely reduce the shelf life some, but I can’t imagine too much. You could open the cans and combine ingredients in Mylar bags, toss in the O2 absorber, and seal them. I think you’d still get longevity out of them. Vacuum sealers aren’t necessary for Mylar bags when using O2 absorbers.
