摘要:
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.
摘要:
The present invention provides a process for concentrated PUFA oil, characterized in that alcoholysis reaction using lipase is carried out in the presence of a small amount of water and at least one compound as an additive selected from magnesium oxide, magnesium hydroxide, calcium oxide and calcium hydroxide, and then separation is conducted to obtain a glyceride fraction.

摘要:
Edible oil containing arachidonic acid obtained from microorganisms belonging to the subgenus Mortierella of the genus Mortierella and being capable of producing arachidonic acid are provided. The oil contain little unsaponifiable matters and, above all, the smallest possible amount of sterol with cyclopropane structure which have not been recognized as food components, and are suitable for the production of foods, in particular, infant formula.Arachidonic acid-containing edible oil originating in microorganisms containing not more than 0.8% by weight, preferably not more than 0.6% by weight of unsaponifiable matters and 20% by weight or more of arachidonic acid. Further, these edible oil contain not more than 0.3% by weight, preferably not more than 0.15% by weight of 24,25-methylenecholest-5-en-3 .beta.-ol. The microorganisms are those belonging to the subgenus Mortierella of the genus Mortierella and being capable of producing arachidonic acid. These microorganisms belong to the species alpine of the genus Mortierella. Foods including the arachidonic acid-containing edible oil. Formula for premature infants, formula for infants, foods for infants, and foods for pregnant women and nursing mothers, including the arachidonic acid-containing edible oil.
摘要:
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.
摘要:
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.
摘要:
To a polyunsaturated fatty acid or its salt or ester was added an antioxidative sesame component and ascorbic acid or an ascorbyl fatty acid ester. To the polyunsaturated fatty acid or its salt or ester, or an oil or fat containing the polyunsaturated fatty acid or its salt or ester having an peroxide value (PV) of 3.0 meq/kg or less and an acid value (AV) of 1.0 or less, and no odor in terms of sensory testing was mixed with an antioxidative sesame component, ascorbic acid or an ascorbyl fatty acid ester, and an external base material, under conditions preventing oxygen from mixing, and the mixture is quickly placed in a hermetic container. The above method provides an external composition containing a polyunsaturated fatty acid or its salt or ester, exhibiting enhanced oxidative stability, and consequently preventing the generation of peculiar odor and peroxides resulting from the oxidation of the polyunsaturated fatty acid.
摘要:
To an organic substance having a double bond such as a polyunsaturated fatty acid was added an antioxidative component containing an antioxidative sesame component and ascorbic acid or an ascorbyl fatty acid ester.The above method provides a composition containing an organic substance having a double bond exhibiting enhanced oxidative stability. Particularly, it extremely improves oxidative stability of fat and oil which contains polyunsaturated fatty acid. General-purpose refined fish oil which is easy to handle can be provided for food, medicine or feed uses.
