| titleOfInvention | A kind of preparation method of high-purity EPA glyceride and DHA glyceride |
| abstract | The invention discloses a preparation method of high-purity EPA glycerides and DHA glycerides, which comprises the following steps: (1) fish oil enzyme catalyzed hydrolysis: adding water, fish oil, and glyceride hydrolase into a reactor, and stirring the reactants to Emulsified state, pH adjustment, the final reaction product is fatty acid and glycerin aqueous solution; (2) Separation and purification of fish oil fatty acid with thin film evaporator and rectification tower to obtain high-purity EPA and DHA; (3) Use lipase to separate EPA and DHA Glycerol is used to synthesize EPA glyceride; (4) DHA and glycerol are synthesized into DHA glyceride by lipase. The method of the present invention does not use chemicals such as ethanol and urea, and the production process is more concise, and the separation method of the rectification tower that is easy to realize large-scale production is used to replace the multi-stage molecular distillation separation method that cannot realize large-scale production, and the production efficiency is improved. , Reduce industrial environmental pollution. |
