lyophilization

Definition

Synonym of freeze-drying.

Etymology

First use appears c. 1894 in the US. lyo- + philos + -ization (alternatively analyzed as lyophilize + -ation), from Ancient Greek λύω (lúō, “to loosen, to dissolve”) + φίλος (phílos, “beloved”) + -ίζειν (-ízein) + Latin -ātiō, due to the dried product being able to rapidly reabsorb the solvent and restore the original substance, hence “lyophil” (solvent-loving). Popularized from 1960 by Louis R. Rey. Cognates exist in other European languages by means of the same construction.
