A method for the transesterification of oils and fats in the presence of a fatty acid, of a fatty acid ester or of another oil or fat by means of an alkaline high - molecular lipase.

摘要

There is proposed a process for the interesterification of oil or fat by treating such oil or fat in presence of a fatty acid or fatty acid ester or different oil or fat wherein a reactor column that is packed with an alkaline high molecular weight lipase preparation containing 0 to 5% moisture is fed with a substrate solution composed of the above oil or fat and fatty acid or fatty acid ester or different oil or fat for a continuous reaction in such a manner that the substrate solution contains 100 to 1800 ppm moisture and 50 to 800 ppm moisture at the inlet and outlet, respectively, of the column.
