Some foods are more easily stored for the long term than others. Examples would be dried beans, canned goods, and home canned fruits, vegetables and meats. I haven’t yet acquired my pressure canner in order to try home canning. I have, however, acquired 5 gallon plastic buckets, Mylar pouches and oxygen absorbers. The list of foods that can be stored in this manner is not exactly short.
So far, I have three kinds of beans (Great Northern, Pinto and Red Kidney), Rice, and Cornmeal. I had read up on the process of putting products into Mylar bags, adding an oxygen absorber (appropriately sized) and sealing the Mylar. I purchased both the 5 gallon size, to fit the whole bucket, and the 1 gallon size. The smaller seemed more efficient to me, as I could store a smaller amount within and not worry about resealing the bag too many times. As of right now, I’m sticking with that decision.
