Drying has a number of close synonyms. Dehydration is the process of depriving a material of its water or the loss of water as a constituent. The term is often used in food-drying operations to describe processes which strive to expel moisture but retain other volatile constituents in the original material, and which are responsible for valuable aromatic and flavoring properties.
