caseicadj.

Brit.

/keɪˈsiːɪk/, U.S.

/keɪˈsiɪk/

Forms: 1800s– caseic, 1900s– caseïc.

Origin: A borrowing from Latin, combined with an English element; modelled on a French lexical item. Etymons: Latin cāseus , -ic suffix.

Etymology: < classical Latin cāseus cheese (see caseous adj.) + -ic suffix, after French caséique (1807 or earlier in acide caséique, attributed to J. L. Proust).

Chemistry. Now rare.

caseic acid n. an acid (supposedly) found in cheese; (in later use also) an acid formed during the hydrolysis of casein.Both substances are of uncertain identity.
