  • Method for producing oil containing polyunsaturated fatty acid using lipase
    Patent number: 10138502
    Abstract: A method for lowering saturated fatty acid content, the method comprising concentrating polyunsaturated fatty acid using a lipase having low reactivity for the polyunsaturated fatty acid to react with a glyceride containing a polyunsaturated fatty acid; wherein the lipase reaction is performed at a temperature of not more than 25° C.
    Type: Grant
    Filed: April 15, 2016
    Date of Patent: November 27, 2018
    Assignee: NIPPON SUISAN KAISHA, LTD.
    Inventors: Hideo Ikemoto, Nobushige Doisaki, Yasuo Umehara
  • Method for producing EPA-enriched oil and DHA-enriched oil
    Patent number: 9556401
    Abstract: Alcoholysis of oils and fats containing EPA and DHA is performed by a lipase having substrate specificity for fatty acids having 18 carbons or less and in the presence of a reaction additive such as magnesium oxide; then the glyceride fraction is separated; alcoholysis of the glyceride fraction is performed by a lipase having substrate specificity for fatty acids having 20 carbons or less and in the presence of a reaction additive such as magnesium oxide; and EPA-enriched oil and DHA-enriched oil are simultaneously obtained.

  • Method for producing oil containing highly unsaturated fatty acid using lipase
    Patent number: 9029584
    Abstract: A method for lowering content of a sterol in a highly unsaturated fatty acid-concentrated oil in a method to concentrate a highly unsaturated fatty acid by using a lipase reaction, may include removing the free form of the sterol from a raw material oil that includes a highly unsaturated fatty acid-containing glyceride prior to performing the lipase reaction; and thereafter concentrating the highly unsaturated fatty acid in the glyceride by using a lipase that is less reactive for the highly unsaturated fatty acid.
