Abstract
Fish oil contains polyunsaturated fatty acids, especially omega-3. Fish oil industry by-product cannot be used because of the low quality so it needs to be purified by treatment with passive filters (centrifugation). The purpose of this study is to determine the best time and speed of passive filter treatment (centrifugation) to improve the quality of fish oil. Fish oil done purification with centrifugation treatments with the time and speed differences. Fish oil treatment has been done then analyzed yield, secondary primary oxidation parameters and clarity values. Treatment of 2500 rpm 45 min is characteristic of the best combination of speed centrifugation treatment and time, seen from the statistical analysis of secondary and primary oxidation parameters and also can meet the standards.
Highlights
Fish oil is one of processed fishery products that contain omega-3 fatty acids such as DHA (Docosahexaenoic Acid) and EPA (Eicosapentaenoic acid) which is essential for health
Crude sardine oil is centrifugated with a combination of treatments speed (2500, 4500, 6500, 8500 and 10500 rpm, respectively) and time (15, 30 and 45 min, respectively) at a temperature of 10°C to separate the soap stock contained in fish oil
Soap stocks mainly composed of water and solvent, free fatty acids and sterols and can contain organic phosphate, Monoacylglycerols (MAG), Diacylglycerols (DAG), Triglycerides (TAG), polyalcohols, carbohydrates and other small parts
Summary
Fish oil is one of processed fishery products that contain omega-3 fatty acids such as DHA (Docosahexaenoic Acid) and EPA (Eicosapentaenoic acid) which is essential for health. Fishmeal and canning process produces by-product sardine oils containing large enough omega-3 fatty acids in high levels and can be used as a source of omega-3 fatty acids. Fish oil from the process can still not be used, it needs to purification step is used as a food source. Suseno et al (2011) stated the quality of fish oil by-product of fish meal and fish canning industry is to feed, not for food, with the content of soapstock is quite high at 20%, the value for the primary oxidation peroxide (peroxide value) 4.4 (meq/kg), free fatty acid value 1.25 (% oleic), panisidine value 31.79 (meq/kg) and total oxidation value of 40.59 (meq/kg).
