Processes for preparing conjugated linoleic acid from conjugated linoleic acid esters

摘要

Processes for preparing conjugated linoleic acid are described wherein a conjugated linoleic acid lower alkyl ester is subjected to hydrolysis in the presence of an enzyme to form a hydrolyzate comprising a conjugated linoleic acid and a lower alkanol, wherein at least a portion of the lower alkanol is continuously removed; the hydrolyzate is separated into an organic phase and an aqueous/alcoholic phase; and the conjugated linoleic acid is separated from the organic phase.
