Freeze-dried Food are meals that have undergone a process called freeze-drying, also known as lyophilization. A sublimation process is used to remove water from food, which consists of converting water from a solid state (ice) to a gaseous state (water vapor) without going through the liquid state.
- The freeze drying process involves freezing the food, then placing it in a vacuum chamber where the air pressure is lowered. Water vapor escapes the food when heat is applied, converting the frozen water in it into water vapor. This leaves behind dehydrated, lightweight food that is shelf-stable and has a long shelf life.
- Backpacking foods are popular among backpackers, hikers, and campers due to their light weight, easy portability, and ability to be rehydrated quickly with boiling water. these meals are also featured in emergency preparedness kits and are favored by astronauts and military personnel.
