PURPOSE:To obtain the title inexpensive fatty oil excellent in sharp melting characteristics with good quality by selective ester interchange reaction of a lauric acid-based fatty oil, etc., using a specific lipase. CONSTITUTION:Firstly, a lauric acid-based fatty oil (e.g. coconut oil, palm kernel oil) or its mixture with other fatty oil (e.g. palm-hydrogenated fat, tallow) is dried so as to be <=200 (pref. 100)ppm in the water content therein. Thence, the product is passed at 0-60 deg.C through a column packed with an immobilized enzyme Which is prepared by fixing on a carrier such as an ion exchange resin a 1,3-site-specific lipase in the form of an aqueous solution in the presence of an enzyme activator such as lecithin followed by drying, and put to selective ester interchange reaction, thus obtaining the objective fatty oil. |
