Abstract:

Oil was extracted from moringa (PKM-1) seed kernel by using supercritical fluid (SC-CO2) extraction process. Supercritical fluid pressures of 100, 150 and 200 bar and temperatures of 40, 50 and 60 °C were considered for SC-CO2 extraction process.  Maximum extraction yield of 37.76 g/100g and extraction efficiency of 98.43% were obtained at supercritical fluid pressure of 200 bar and temperature of 40 °C. The SC-CO2 temperature had significant effect on most physico-chemical properties than the pressure. Physico-chemical properties viz., density, specific gravity, color value (b*), acid value and saponification value decreased with increase in extraction temperature. Colour value L*, color value a*, iodine value and peroxide value increased with increasing temperature. The physico-chemical properties of SC-CO2 extracted moringa seed kernel oil were found to be superior over solvent extracted oil. The production cost of oil from moringa (PKM-1) seed kernel using supercritical fluid extraction equipment was estimated and benefit cost ratio was found to be 1.83:1.
