Every year, a large amount of by-products produced by fish processing industries is discarded or used for less profitable purposes. In this study, we will describe technique producing high-quality, edible oil from the viscera yellowtail (Seriola quinqueradiata) which can be served as source omega polyunsaturated fatty acids. Yellowtail was extracted using supercritical carbon dioxide (SC-CO2) extraction and Soxhlet apparatus. SC-CO2 carried out in semi-batch process at temperature pressure ranging 40°C to 50°C 15 30 MPa, respectively, CO2 flow rate 27 g/min 3 hr. During experimental influence operation parameters such time, operating pressure, on yield investigated. The highest found Soxhlet-ethanol (56.13%) followed n-hexane (48.48%) (40.87%). then characterized ascertain its quality. SC-CO2-extracted oils have lower free acid, p-Anisidine, peroxide values compared Soxhlet-extracted oils. greatest omega-3 acids (20.14%) MPa 40°C. Practical applications our conventional extraction. extraction, effect different factors like temperature, quality also analyzed. Supercritical comparatively better oxidative than Moreover, contain reasonable acids, among them docosahexaenoic acid eicosapentaenoic play crucial role preventing cardiovascular diseases improve physical mental health. Therefore, utilization obtained good human-grade food contributes industry, decreases environmental pollution, reduces waste cost.
