Freeze-drying

Freeze-drying
Freeze-dry Freeze"-dry` (fr[=e]z"-dr[imac]`), v. t. [imp. & p. p. {Freeze-dried}; p. pr. & vb. n. {Freeze-drying}.] to remove the moisture from (e.g. food) by first freezing and then subjecting to a high vacuum; -- used as a mild method for drying foods or chemicals while causing little decomposition, in contrast to heat-drying.

Note: This is a relatively gently drying process used to preserve food or sensitive biological materials. For biochemical materials, the term {{lyophilize}} is often used. [PJC]
