Lipase-catalysed esterification of marine oil

摘要

A process for esterifying a marine oil composition containing EPA and DHA as free fatty acids to form a free fatty acid fraction enriched in at least one of these fatty acids compared to the starting composition, comprising: (1) Reacting the marine oil composition with glycerol in the presence of a lipase catalyst under reduced pressure and organic solvent-free conditions, and (2) Separating a free fatty acid fraction enriched in at least one of EPA and DHA by molecular distillation.
