CONCENTRATION OF FATTY ACID ALKYL ESTERS BY ENZYMATIC REACTIONS WITH GLYCEROL

摘要

An enzymatic process for the kinetic separation of alkyl esters under organic solvent free conditions is disclosed. Alkyl esters obtained from e.g. fish oil are reacted with glycerol, in the presence of water, at different rates in an evacuated chamber. The reaction is terminated prior to reaching equilibrium and the enriched alkyl ester fraction is isolated from the reaction mixture by short path distillation.
