    • PROBLEM TO BE SOLVED: To improve the merit of an enzymatic method for producing a triglyceride containing a poly-unsaturated fatty acid. SOLUTION: The method for enzyme-catalytically producing the triglyceride containing the poly-unsaturated fatty acid comprises the following steps: (a) a step for promoting the reaction of the poly-unsaturated fatty acid and/or a 1-4C alkyl ester thereof with glycerol in the presence of an immobilized enzyme under vacuum for the formation of the triglyceride by the addition of an additive selected from the group consisting of a weak basic salt, a complexing agent and an ion-exchanger, and/or the addition of the weak basic salt, and/or the addition of a solvent or a gas-shaped codistillation agent, and/or the addition of a glycerol-bonding absorbent, and/or the heat treatment of an intermediate product of a partial glyceride; (b) a step for removing the immobilized enzyme from the triglyceride by separation or filtration; and (c) a step for removing the remaining fatty acid and/or 1-4C alkyl ester thereof from the triglyceride by distillation, purification or extraction.
