WIPO Patent Application WO/2021/196881
Kind Code:
A1
Abstract:
Disclosed is a preparation method for a triglyceride-type polyunsaturated fatty acid, comprising the following steps: (1) mixing raw material grease with water, homogenizing, and carrying out lipase catalyzed hydrolysis to obtain free fatty acid salt and glycerol; (2) separating the fatty acid salt from glycerol to obtain the fatty acid salt; (3) acidifying the fatty acid salt to obtain a free fatty acid; (4) drying the free fatty acid, and carrying out molecular distillation treatment to obtain long-chain polyunsaturated fatty acid; and (5) mixing the polyunsaturated fatty acid with glycerol, and carrying out esterification reaction under the catalysis of lipase to obtain a triglyceride-type polyunsaturated fatty acid. In the triglyceride-type polyunsaturated fatty acid obtained by the described method, the oxidation loss of polyunsaturated fatty acid is small and there is no chemical substance residue. Also disclosed are a triglyceride-type polyunsaturated fatty acid and an application thereof in preparing infant formula food, healthy food, health food or medical products.
