THE OIL EXTRACTION FROM EEL (ANGUILLA BICOLOR BICOLOR) BONE AS BY-PRODUCT FROM KABAYAKI PROCESSING INDUSTRY

Abstract

Fish oils have been recognized as good sources of polyunsaturated fatty acids (PUFA) which are widely used for pharmaceutical purposes and as food supplements. In this study, fish oil from eels (Angguilla bicolor bicolor) bone were extracted using a Bligh and Dyer methods. The fatty acid composition of the oil was analyzed and quantified using gas chromatography. Results showed that the total yield of by-product of Eel (Anguilla bicolor bicolor) reached 26,38 %, the lipid content of eels bone was 17.33 ± 0.58 g/100 g. Yield of eel bone oil extracted by Bligh and Dyer method was 17.12%. In the fatty acid analysis of eel bone oil, it was discovered that SFA was 19.87%, MUFA was 25.84%, and PUFA was 13.84%. The major fatty acids in the oil from the bone were palmitic acid (13.58%), oleic acid (20.94%), linoleic acid (4.01%), EPA (1.57%), and DHA (4.84%).
