Abstract
The catfish (Pangasius micronema Blkr.), milkfish (Chanos chanos Forsskal.) and snakehead (Chana striata Bloch.) are the most important fishing commodities in Indonesia. Its fatty acid content makes it a possible source of fish oil for nutritional supplement use. The extraction method influenced the quality of the fish oil produced. Wet rendering, also known as wet extraction, is the most popular extraction method for separating fish oil. The purpose of this research is to investigate how wet rendering extraction affects the fatty acid content and physicochemical profiles of catfish, milkfish and snakehead fish. The fatty acid profile was determined with a Gas ChromatographyFlame Ionization Detector (GC-FID). The quality of fish oil was determined according to the standard method of the Association of Official Analytical Collaboration (AOAC) International protocol. The results of this study indicated that the wet rendering extraction method produces various fatty acid content and physicochemical characterizations of catfish, milkfish, and snakehead fish oils. The acid value of catfish oil fulfilled the fish oil standards. In terms of peroxide value, milkfish and snakehead fish oil satisfied the criteria. In the iodine value parameter, snakehead fish oil matched the standard, while catfish oil and milkfish oil met the saponification value parameter. The highest content of omega-3 fatty acids was found in snakehead fish oil, while the highest levels of omega-6 and omega-9 were reported in milkfish oil and catfish oil, respectively.
