Abstract:  With viscera of Scortum barcoo as material, extraction and refinement of fish oil from Scortum barcoo as well as itsfatty acid composition were systematically studied. Results showed that water bath was used as the method of crude oil extraction: under 85℃ and extract 40min. The method of refinement was by adding 5% caustic soda in order to neutralize free fatty acids, and the amount being added was 1.75% of viscera amount. Fish oil of Scortum barcoo viscera obtained is of clear and fresh yellow liquid; and its physicochemical properties index are all conformed to fish oil standard. Furthermore, the fatty acid compositions of crude oil and refined oil were all analyzed by gas chromatography.

Key words: Scrotum barcoo, extraction, refinement, fatty acid
