Freeze Drying


Freeze Drying 101

Freeze drying or lyophilization, is the process of removing moisture from a product without compromising the quality or structure of the product. The typical freeze-dried process starts by placing frozen items in a vacuum chamber and the surrounding pressure is reduced. This causes the frozen water in the product to transition from a solid to a gas, a process known as sublimation. The water vapor is then collected and removed from the chamber, leaving behind a dehydrated product that can be stored for long periods of time without refrigeration. The end result is a product that retains its original shape, texture, and flavor, making freeze drying an ideal preservation method for many types of food.
