Supercritical carbon dioxide (SCO2) and an organic solvent, hexane were used to extract oil from anchovy The SCO2 extraction was carried out at temperatures ranging from 35 to 60ºC and pressures ranging from 20 to 40 MPa. The flow rate of CO2 was 22 g/min and it was constant entire the extraction period. The extracted oil was analysed by Gas Chromatography (GC) for fatty acids compositions. A high percentage of polyunsaturated fatty acids especially eicosapentaenoic acid (EPA, C20:5) and docosahexaenoic acid (DHA, C22:6) were found in the anchovy oil obtained by SCO2 extraction. EPA and DHA have been shown to be important for the prevention of a range of human diseases and disorders
