| titleOfInvention | Method for preparing fatty acid ethyl ester with Omega-3 content of more than 90 percent |
| abstract | The invention discloses a method for preparing a fatty acid ethyl ester with Omega-3 content of more than 90 percent by taking fish oil as a raw material. According to the method, the fish oil serves as a raw material, and the method sequentially comprises the following steps of: removing free fatty acids through molecular distillation prepurification; performing twice transesterification reactions on fish oil and ethanol to prepare fatty acid ethyl ester by taking sodium ethoxide as a catalyst; performing primary purification on the fatty acid ethyl ester through molecular distillation; performing secondary purification on the fatty acid ethyl ester through a urea inclusion technology; purifying and discoloring the fatty acid ethyl ester subjected to urea inclusion through molecular distillation; performing activated clay adsorption and reducing the peroxide value; and removing anisidine from a sodium hydroxide ethanol solution, so that the fatty acid ethyl ester with Omega-3 content of more than 90 percent is obtained. The method has the beneficial effects that a production method which is not used in China at present is provided; and according to the method, the fatty acid ethyl ester product with Omega-3 content of more than 90 percent is produced. The fatty acid ethyl ester obtained by the method has the Omega-3 ethyl ester content of more than 90 percent, and each quality standard accords with the standards of European pharmacopoeia and United States pharmacopeia; and moreover, the fatty acid ethyl ester can be used for nutritious supplementary, medicines, foods and food additives and is high in economic value. |
