Freeze Drying is a method of food preservation that rapidly freezes whatever is being preserved, then adding heat to it in a vacuum. This process removes all moisture from the food or what is being preserved by allowing the moisture to leave the substance as a gas rather than a liquid - the vacuum pulls it out rapidly. The heat used is enough to cause moisture release but not enough to cause the frozen material to thaw. The resulting dried food can be preserved for a very long time without spoiling.
To reconstitute the preserved food, normally all you have to do is to add water, which replaces the moisture that was originally removed during the process.
