Understanding Freeze Drying
Freeze drying, or lyophilization, is a process that removes moisture from food, allowing it to be preserved for extended periods. This method involves freezing the food, followed by reducing the surrounding pressure to allow the frozen water in the food to sublimate directly from solid to gas. The result is lightweight, shelf-stable food that retains its original flavor, color, and nutritional value, making it superior to other preservation methods like canning or dehydrating.
