Abstract

Six brands of encapsulated fishoil products and five fishes were analyzed for their contents of eicosapentaenoic acid (EPA 20 :5 n-3) , docosahexaenoic acid(DHA 22: 6 n-3) and tocopherols. In both of the fish oil products and the fishes, major fatty acids were palmitic acid, oleic acid, eicosapentaeoic acid and docosahexaenoic acid and fatty acid compositions were also similar pattern each other. EPA showed variable amounts from 19.2 to 50.3% in the oil products whereas DHA were 13.2% to 28.3% inthe fishes. Tocopherols were studied in relation to the oxidative stability of fish products no relation was observed. However the amount of tocopherols in fish oil proudcts were higher than that of fishes. Contents of EPA, DHA and tocopherols in encapsulated fishoil products oil products were variable comparing with manufactures' claimed contents.
