Freeze-drying is a process of removing water from food by sublimation, which is the direct transition of a substance from a solid to a gas without passing through the liquid state. Freeze-drying is often used to preserve food because it removes the water that bacteria and other microorganisms need to grow. Freeze-dried food is also lightweight and easy to store, making it a good choice for backpackers and other outdoor enthusiasts.
