TWO-STAGED PROCESS FOR THE PREPARATION OF FATTY ACIDS FROM FAT OR OIL COMPRISING ONE STEP OF ENZYMATIC HYDROLYSIS EMPLOYING AN IMMOBILIZED LIPASE AND AN OTHER STEP OF HIGH TEMPERATURE AND PRESSURE HYDROLYSIS

摘要

A process for producing fatty acid by hydrolyzing oil and fat, which comprises: a first step of partially hydrolyzing oil and fat by either of the following method (a) or (b), and a second step of hydrolysis by the other method: (a) enzymatic hydrolysis using an immobilized enzyme which is an enzyme immobilized on a support and (b) high pressure and temperature hydrolysis. A method of efficiently producing fatty acid with a reduced content of trans-unsaturated fatty acid in the constituent fatty acids and having a good appearance with reduced coloring by hydrolysis of oil and fat is provided.
