2013
The invention provides a method for preparing glyceride-type fish oil rich in n-3 polyunsaturated fatty acids. The method comprises the following steps: heating and stirring fish oil acetate, short-chain acid glyceride and immobilized lipase under a vacuum condition till complete reaction, and then removing unreacted fish oil acetate to obtain the glyceride-type fish oil rich in n-3 polyunsaturated fatty acids. According to the method provided by the invention, the defect that a reaction can not be smoothly carried out as glycerinum is easy to wrap immobilized enzyme in a traditional method for preparing the glyceride-type fish oil rich in n-3 polyunsaturated fatty acids can be overcome.
