Freeze drying is a relatively recent method of preserving food. It includes freezing the food, then removing almost all the moisture in a vacuum chamber, and finally sealing the food in an airtight container. Freeze dried foods can be easily transported at normal temperatures, stored for a long period of time, and consumed with a minimum of preparation. Once prepared, freeze-dried foods have much the same look and taste as the original, natural products.
The basic idea of freeze-drying is to completely remove water from some material, such as food, while leaving the basic structure and composition of the material intact. There are two reasons someone should need to do this with food:
- Removing water keeps food from spoiling for a long period of time.
- Freeze-drying significantly reduces the total weight of the food
