dc.description.abstractSupercritical fluid extraction (SFE) is an emerging technology for extraction and isolation of valuable compounds from natural products. Supercritical carbon dioxide (SCO2 ) is one of the most commonly used solvents in SFE and has gained importance as a “green” or environment friendly solvent. In this study, polyunsaturated fatty acid (PUFA) rich oil from freeze dried yellowfin tuna (Thunnus albacares) red meat was extracted using supercritical carbon dioxide. Red meat, a by-product obtained from tuna processing forms about 9-11% of the total body weight of tuna. Lipid extraction from freeze dried tuna meat was performed at a temperature of 60oC and pressure of 35 MPa for 3 h. The flow rate of CO2 was kept constant at 175 l h-1. The extracted oil was collected in two separators both held at 5 MPa pressure and temperature of 50oC and 40oC respectively. The antioxidant tocopherol (0.5%) was added to the extracted oil and stored at 2-4oC for further analysis. The yield of oil obtained was 5% and it was found to be rich in polyunsaturated fatty acids like docosahexaenoic, eicosapentaenoic and arachidonic acid constituting 31, 5 and 4% of the total fatty acids respectively. Palmitic and stearic acid were the most abundant saturated fatty acids present constituting 23 and 15% of total fatty acids respectively. Oleic acid contributed 18% of the total fatty acids. SFE was effective in extraction of fatty acids from tuna red meat with minimal losses.en_US
