Sun drying, air drying and freeze drying are examples of commonly used methods for drying food, another effective method is using superheated steam to dehydrate.

Water and moisture binds bacteria and drying food can elongate the shelf life, but food dehydration have more advantages than that. Drying also reduces size and weight which means easier and cheaper storage and transportation.
