PURPOSE: A producing method of oil with reduced content of saturated fatty acid is provided to reduce the production costs for the oil, and to separate-remove the saturated fatty acid by hydrolyzing palm oil into fatty acid and glycerol. CONSTITUTION: A producing method of oil with reduced content of saturated fatty acid comprises the following steps: hydrolyzing palm oil using enzyme specific to 1, 3 locations to obtain fatty acid and glycerol; separating the fatty acid into unsaturated fatty acid and the saturated fatty acid; fractionating oleic acid from the unsaturated fatty acid; firstly trans-esterificating the glycerol and the oleic acid without a solvent for 4-6 hours; and secondly trans-esterificating the obtained first reaction solution for 4-8 hours. The hydrolyzing process is performed by mixing 100 parts of palm oil by weight and 20-60 parts of water, and stirring the mixture in the speed of 250-300rpm. The enzyme specific to 1, 3 locations is 10-15% lipozyme TL IM. |
