The oil in mackerel muscle was extracted using an environment friendly solvent, supercritical carbon dioxide (SC-CO2) at a semibatch flow extraction process and an n-hexane. The SC-CO2 was maintained at a temperature of 45°C under pressures ranging from 15 to 25 MPa. The flow rate of CO2 (27 g/min) was constant during the entire 2 h extraction period. The fatty acid composition of the oil was analyzed using gas chromatography (GC). Significant concentrations of eicosapentaenoic acid (EPA) acid and docosahexaenoic acid (DHA) acid were present in the SC-CO2 extracted oil. The oil extracted using SC-CO2 exhibited increased stability compared with n-haxane extracted oil. Particles of mackerel oil together with the biodegradable polymer, polyethylene glycol (PEG) were formed using a gas saturated solution process (PGSS) with SC-CO2 in a thermostatted stirred vessel. Different temperatures (45-55°C), pressures (15-25 MPa) and a nozzle size 400 μm were used for PGSS with a 1 h reaction time. The stability of mackerel oil in the particles did not changed significantly. © 2014 The Korean Society of Fisheries and Aquatic Science.
