METHOD OF CONCENTRATION AND SEPARATION OF UNSATURATED FATTY ACID ESTERS |
摘要 |
This invention provides a method of concentrating and separating gamma -linolenic acid esters and/or arachidonic acid esters characterized in that a fatty acid ester mixture containing gamma -linolenic acid ester and/or arachidonic acid ester is brought in contact with crystalline aluminosilicate zeolites to make adsorption and desorption. According to this invention, high purity gamma -linolenic acid and/or arachidonic acid ester(s) may be obtained on industrial scale. |
