| titleOfInvention | Eicosapentaenoic acid alkyl ester-containing composition and method for producing same |
| abstract | The present invention provides an eicosapentaenoic acid-containing composition having high concentration and high purity. A method for producing an eicosapentaenoic acid alkyl ester-containing composition, which comprises (1) a process wherein a starting material oil containing an eicosapentaenoic acid alkyl ester is brought into contact with an aqueous solution containing a silver salt, and subsequently an aqueous layer is recovered, (2) a process wherein an organic solvent is added to the aqueous layer, and subsequently an organic solvent layer is recovered, and (3) a process wherein the organic solvent layer is subjected to vacuum distillation at a temperature of 180-188°C at a column top vacuum degree of 0.7 Pa or less, thereby recovering the eicosapentaenoic acid alkyl ester from the organic solvent layer. |
