  • Method for purifying polyunsaturated fatty acid by using continuous reactor
    Patent number: 11148993
    Abstract: The present invention relates to a method for purifying polyunsaturated fatty acid using a continuous reactor, and the method comprises: (a) complexing step, (b) cleaning step, (c) extracting step, and (d) concentrating and drying step. The method of the present invention reacts a polyunsaturated fatty acid and a silver salt aqueous solution in a continuous reactor to form a complex of the polyunsaturated fatty acid and silver, and then cleans the complex with a first organic solvent to improve the purity of the complex; afterwards, a second organic solvent is used to extract the purified polyunsaturated fatty acid. The method of the present invention can continuously produce polyunsaturated fatty acids with high yield and high purity.
