Abstract
This invention discloses a method for improving n-3 polyunsaturated fatty acid enrichment efficiency in glyceride, belonging to the field of deep processing of oil. The method of this invention includes providing oil, lipase and metal ionic liquid into a reactor. After a reaction time, a mixture is obtained and free fatty acid is removed from the mixture, and the product is the n-3 polyunsaturated fatty acid-rich glyceride. Compared with the traditional chemical method, the method of this invention is characterized by mild reaction conditions and producing lower level of by-products. Meanwhile, metal ions selected in the present invention are able to promote the hydrolysis of lipase, solving the problem of long reaction time in the conventional enzymatic method. Rapid hydrolysis is achieved by this method so as to realize enrichment of EPA and DHA in glyceride.
