Liu Huizhi

Abstract

Objective Extracting high content of DHA, EPA from rude fish oil. Methods Extracting fish oil ethyl ester with silver nitrate-water method. Results With silver nitrate-water method extracting three kinds of products from rude fish oil were gained(1) The total content of EPA and DHA mixture was higher than 95%. (2) The content of DHA was higher than 95%. (3) The content of EPA was higher than DHA. Conclusion The researching technology may reduce the production cost of high content of EPA and DHA. The method researched can increase the stabilities of DHA, EPA, and decrease the side effects of the products.
