| titleOfInvention | Eicosapentaenoic acid alkyl ester-containing composition and method for producing same |
| abstract | Provided is a high-concentration and high-purity eicosapentaenoic acid-containing composition. A method for producing an eicosapentaenoic acid alkyl ester-containing composition, the method includes: (1) bringing a raw oil that contains an eicosapentaenoic acid alkyl ester into contact with an aqueous solution that contains a silver salt, and then collecting an aqueous layer; (2) adding an organic solvent to the aqueous layer, and then collecting an organic solvent layer; and (3) subjecting the organic solvent layer to vacuum distillation at a temperature of 180 to 188°C and a tower top vacuum degree of 0.7 Pa or below, to recover the eicosapentaenoic acid alkyl ester from the organic solvent layer. |
