Definitions

1. Preserves a substance by freezing it and then removing the water through evaporation under vacuum, as is done with foods or medicines

Etymology: "Lyophilises" is the third-person singular form of the verb "lyophilise", meaning to freeze-dry a substance, usually by freezing it and then removing the water through vacuum sublimation. The verb is built from Greek roots: "lyo-", from "lyein" meaning "to loosen or dissolve," and "-philise", from "philos" meaning "loving," so the term literally describes a substance that loves to dissolve or take up solvent, a sense that reflects its origin in describing how a material is processed.

Synonyms: freeze-dry
