I am looking at doing some overnight camping trips and want to take dehydrated meals with me and have a few questions. Can I dehydrate canned foods such as chili? I like Hormel Turkey chili and I know one of the biggest concerns with dehydrating food is fat content and its pretty low in fat. Will that work? Also, I see a lot of people talking about food going rancid. How do you tell in dehydrated food? With hamburger, is it worth doing on my own or buying "store bought" dehydrated hamburger? I know that doing dairy and eggs are extremely difficult so I will just use the ready made stuff for that but wondered on the meat portion and premade type meals. Also, any suggestions on foods to take? The hikes will be 2-3 days and water access is good. Thanks for any input.
