Oil was extracted from moringa (PKM-1) seed kernel by using supercritical fluid (SCCO2) 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 g/100g and extraction efficiency of were obtained at supercritical fluid pressure of 200 bar and temperature of 40 °C. | 2021 10 03 1390-1401 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 10 Number 03 2021 Journal homepage http Original Research Article https Effect of Supercritical Carbon dioxide SC-CO2 Temperature and Pressure on Physico-chemical Properties of Moringa Moringa oleifera Lam.

The SC-CO2 chemical properties 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 Article Info saponification value decreased with increase in extraction temperature. Colour value L color value a iodine value and peroxide value increased with increasing temperature. The Accepted physico-chemical properties of SC-CO2 extracted moringa seed kernel oil were found to be 12 February 2021 superior over solvent extracted oil. The production cost of oil from moringa PKM-1 seed Available Online kernel using supercritical fluid extraction equipment was estimated and benefit cost ratio 10 March 2021 was found to be 1.
