Method for preparing octacosanol ester through enzyme catalysis

The invention discloses a method for preparing octacosanol ester through enzyme catalysis, belonging to the technical fields of foods, medicines, chemical industry, cosmetics and the like. The octacosanol ester is synthesized under the catalytic action of a nonaqueous-phase lipase by taking octacosanol as a raw material and fatty acid as an acyl donor. The method is mild in reaction condition, little in side reaction, simple in separation, environment-friendly and the like. By using the method, the oil solubility of octacosanol can be improved, the bioavailability of octacosanol can be increased, and the actual application range of octacosanol is greatly widened.
