Sometimes people who prep also can and store their own food. However, that food isn’t going to last forever. You need to be able to tell when food is inedible, but that doesn’t mean you need to toss it.
Rancid food is the result of fat molecules becoming oxidized. If heat is present the reaction will occur faster; the same goes for light and foods containing polyunsaturated fats.
Rancid is often a term used across a large group of foods. However, rancidity can only occur when oils oxidize, meaning nuts, whole flours, brown rice, seeds, and vegetable oil are the groups actually affected.
Rancid foods or oils can still be used on the homestead though. While you may want to avoid baking or cooking with rancid foods or oils, you can easily use them as a lubricant. Or you can use the rancid products for lamp oil, rust preventative or furniture conditioner and polisher. Some people even use it to make homemade soap.
You can also make a candle, such as the one portrayed in this video.
Some foods are safe to eat rancid, which may be what you have to do in a survival situation. Check out these other food sources you may use in order to survive.
