Patent number: 7767427Abstract: 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.Type: GrantFiled: September 25, 2008Date of Patent: August 3, 2010Assignee: Suntory Holdings LimitedInventors: Kengo Akimoto, Motoo Sumida, Kenichi Higashiyama, Shigeaki Fujikawa

Publication number: 20100113390Abstract: The present invention provides a fucoidan-derived low molecular weight compound with a good quality of taste, which has a specified structure and function and is free from problems in absorption, antigenicity, uniformity, an anticoagulant activity and so on, which problems arise when developing fucoidan, a sulfated polysaccharide having an extremely large molecular weight, as drugs or health foods. As a result of analyzing low molecular weight compounds obtained by acid hydrolysis of fucoidan, the inventors have identified fucoidan oligosaccharides (I) to (XI). Further, these oligosaccharides have been found to have anti-obesity and/or blood glucose elevation suppressing effects through inhibition of carbohydrate and/or lipid absorption as a result of ?-glucosidase inhibition and/or lipase inhibition.Type: ApplicationFiled: January 26, 2007Publication date: May 6, 2010Applicants: SUNTORY HOLDINGS LIMITED, TROPICAL TECHNOLOGY CENTER LTD.Inventors: Shigeaki Fujikawa, Yuko Fukui, Hiroshi Watanabe, Yuji Nonaka, Takeshi Yasumoto, Hideo Naoki

Patent number: 5660838Abstract: Xylobiose-containing skin preparations for external use are disclosed. Skin preparations for external use into which xylobiose may be incorporated include cosmetics such as clear lotions, milky lotions, packs and lip treatments, drugs or quasidrugs such as ointments and cataplasms, hair-care products such as rinses and hair conditions, and detergents such as hair shampoos and body shampoos. Xylobiose is typically contained in an amount of 0.0001-20 wt %, preferably 0.1-10 wt %, of the total amount of the skin preparation on a dry solids basis. The incorporation of xylobiose is effective not only in preventing the occurrence of stickiness, color change and malodor in the skin preparations but also in providing enhanced moisture retention and reducing excessive roughness and dryness of the skin and hair.Type: GrantFiled: February 24, 1995Date of Patent: August 26, 1997Assignee: Suntory LimitedInventors: Kunimasa Koga, Takumi Kobayashi, Shigeaki Fujikawa, Masako Sawada
