Abstract

See full text

The disclosure discloses an enzymatic method for preparation of lecithin polyunsaturated fatty acids (PUFAs), and belongs to the technical field of separation and application of enzyme. A heat treatment procedure is added after a reaction substrate is in contact with an enzyme to adjust the ratio of sn-1 lysophospholipid PUFAs to sn-2 lysophospholipid PUFAs in a reaction product and to promote the production of sn-2 lysophospholipid PUFAs, thereby promoting the production of lecithin PUFAs, which greatly increases the production efficiency of lecithin PUFAs and the lecithin PUFA content in the product. With simple operations and high reaction rate, the method can significantly increase the content of lecithin PUFAs in the product, can effectively avoid the oxidation of PUFA, and has high economic benefits and promising industrial application prospects.
