What Is Freeze-Dried Food?
Freeze-dried food is food that has had almost all its water removed. The process happens through freezing and then sublimating the ice under low pressure. The result is light, dry food that keeps its shape, taste, and most of its nutrients.
Popular freeze-dried items include:
-
Sliced strawberries
-
Scrambled eggs
-
Yogurt drops
-
Chicken bites
These foods can last 20–30 years if stored properly. That’s why they’re popular for backpackers, survivalists, and smart households.
