Freeze-drying



Freeze-drying, or lyophilization, process that removes water from foods, drugs, and other substances, preserving the items for later use. Unlike other food-drying processes, the costly freeze-drying method freezes the items, then changes any frozen moisture into water vapor in refrigerated vacuum chambers. Freeze-dried substances retain most of their original characteristics, do not shrink, and are easily dissolvable.
