Freeze drying is a good way to preserve perishable fruits. Turn them to light weight and easy storage fruit snacks, as well as add value to them. This because of the unique working theory of freeze drying is sublimation, which result only water is removed. Nutrients, vitamins, flavor, structure and tastes are well preserved. So lyophilized fruit is healthy to eat.
