Process for producing fat comprising triglyceride containing highly unsaturated fatty acid

摘要

New method for preparing fat comprising a triglyceride having a medium chain fatty acid bonded to the 1 and 3 position and a highly unsaturated fatty acid bonded in the 2 position comprises treating a medium chain fatty acid derivative and starting material fat with a lipase fixed to a porous ion-exchange resin support having a pore diameter of at least 100Å. New method for the preparation of a fat comprising a triglyceride having a medium chain fatty acid bonded to the 1 and 3 position and a highly unsaturated fatty acid bonded in the 2 position comprises treating a medium chain fatty acid derivative and starting material fat with a lipase fixed to a porous ion-exchange resin support having a pore diameter of at least 100Å. The lipase specifically acts on the 1 and 3-position ester bonds and the starting material fat comprises at least one omega-6 18C or more fatty acid containing at least 3 double bonds and/or omega-9 18C or more fatty acid containing at least 2 double bonds and no omega-3 highly unsaturated fatty acids. An independent claim is also included for fats prepared by the above process. ACTIVITY : Antiarteriosclerotic; Thrombolytic; Anticoagulant; Cytostatic. MECHANISM OF ACTION : None given.
