Patent number: 11198893Abstract: Provided is a method for producing an unsaturated fatty acid oxide (e.g. ?3 fatty acid oxide) that is new and has more beneficial features compared to conventional technologies. This method uses a lipoxygenase-containing composition (e.g. a lipoxygenase-containing composition derived from beans) as a lipoxygenase enzyme, and also uses a freezing method with organic solvent extraction. The present invention makes it possible to produce an unsaturated fatty acid oxide (e.g. ?3 fatty acid oxide) efficiently and at a low cost. The present invention also provides a pharmaceutical composition containing an ?3 fatty acid oxide isolated and purified by this method as an active ingredient.Type: GrantFiled: June 19, 2017Date of Patent: December 14, 2021Assignee: Bizen Chemical Co., Ltd.Inventors: Shiho Saito, Yoshihisa Misawa, Naomichi Baba, Hiroshi Tabata, Tadahiro Tsushima, Jun Fujii
