  • Patent number: 7767427
    Abstract: The present invention relates to a production method of an oil containing triglyceride in which medium chain fatty acids are bound to the 1- and 3-positions of the triglyceride and polyunsaturated fatty acid is bound to the 2 position by allowing lipase, which specifically acts on ester bonds at the 1- and 3-positions that has been immobilized on a porous ion exchange resin support having a pore size of about 100 Angstroms or more, to act on a mixture of medium-chain fatty acids and raw material oil containing at least one polyunsaturated fatty acid selected from the group consisting of ?6 series polyunsaturated fatty acid having 18 or more carbon atoms and 3 or more double bonds and ?9 series polyunsaturated fatty acid having 18 or more carbon atoms and 2 or more double bonds, but not containing ?3 series polyunsaturated fatty acid, oils and fats or triglycerides obtained by that method, and the use of the oils and fats or triglycerides in a food, beverage or pharmaceutical composition.

  • Patent number: 7709236
    Abstract: A process for producing a crude oil having lowered unsaponifiable matter content and/or ester-type sterol content and comprising a highly unsaturated fatty acid as a constituent fatty acid, characterized in that a microorganism capable of producing a fat or oil comprising an unsaturated fatty acid as a constituent fatty acid is cultured in a medium containing a nitrogen source concentration of 2 to 15% within a culture tank equipped with an agitation impeller satisfying the requirement that the ratio of the diameter of agitation impeller (=d) to the inner diameter of the culture tank (=D) is d/D=0.30 to 0.6.

  • Publication number: 20050228188
    Abstract: The present invention provides an astaxanthin medium-chain fatty acid ester, which is expected to be applied in the fields of food, cosmetics and pharmaceuticals, and has higher digestibility and tissue penetration than long chain fatty acid ester form astaxanthins. When the synthesis of an astaxanthin medium-chain fatty acid ester is attempted using the catalytic action of lipase by conventional methods, ester cannot be formed. However, according to the present invention, a composition comprising an astaxanthin medium-chain fatty acid monoester and/or diester is produced by adding a certain amount of water into a reaction system and reacting an astaxanthin or a long chain fatty acid ester thereof with a medium-chain fatty acid, a triglyceride thereof or a suitable ester. Moreover, these monoesters and/or diesters are isolated, as necessary. The present invention further provides food or cosmetics comprising the composition of the present invention.
