PRODUCTION OF TRIGLYCERIDE CONTAINING HIGH-PURITY LONG-CHAIN HIGHLY UNATURATED FATTY ACID

摘要

PURPOSE: To efficiently produce a triglyceride containing high-purity long-chain highly unsaturated fatty acid in production of the long-chain highly unsaturated fatty acid-containing triglyceride using an immobilized lipase. ;CONSTITUTION: The temperature of a reactor for reacting a mixture of long- chain highly unsaturated fatty acid-containing fats and oils and fatty acids prepared by hydrolyzing the long-chain highly unsaturated fatty acid-containing fats and oils with an immobilized lipase and the temperature of a storage tank for storing a mixed solution returning from the reactor are controlled at 10 to -50°C. Consequently, a saturated fatty acid having a high melting point among fatty acids formed by transesterification of the lipase is precipitated in the storage tank and only the mixed solution is circulated between the reactor and the storage tank to synthesize a long-chain highly unsaturated fatty acid ester and/or to enhance its purity.;COPYRIGHT: (C)1994,JPO&Japio
