ENZYMATIC TRANSESTERIFICATION OF LIPID AND ENZYME USED THEREIN

摘要

A method for the enzymatic transesterification useful for modification of a lipid, which comprises continuously or repeatedly contacting an enzyme or an enzyme preparation having transesterification activities with a fresh supply of a dried fatty ester substrate such as fats and oils of glycerides. The enzyme or the enzyme preparation has transesterification activities (Kr value) of 0.01 or more as well as lipolytic activities. The enzyme preparation is prepared by dispersing, adsorbing or bonding an enzyme having lipolytic activities in or to a carrier and drying the resulting mixture at an adequately slow initial drying rate to activate or increase the transesterification activities of the enzyme.
