What Does Freeze-Drying Do to Nutritional Value?
Freeze-dried foods can lose a small but imperceptible percentage of some nutrients, though the loss of nutrients doesn’t affect the taste. Freeze-dried food keeps longer and is as close to fresh as possible when compared to other methods of long-term food storage.
Does Freeze-Drying Remove Nutrients?
