|Abstract:||The study involved the extraction of oil from Moringa oleifera (MO) kernels using supercritical fluid extraction (SFE) technique. The arrays of operating parameters are extraction condition, loading con-figuration, and SC-CO2with ethanol addition for substrate pretreatment. It identifies a combination of operating parameters that provide a higher yield. The experiments were conducted in the pressure range of 15–30 MPa, 35–60 ◦ C temperature interval, average particle size of 0.16–1.12 mm and CO2flow rate of 0.5 m3 /h. Adding 10% EtOH for substrate pretreatment, increased 10% in the yield. No significant dif-ference in yield and fatty acid content between the oil from SC-CO2-EtOH and Soxhlet extraction with n-hexane was detected. Loading the seeds in multiple-staged trays increased to as much as 26.89% in the yield against randomly packed configuration. Response surface methodology, predicted an optimal oil yield of 37.84% at a pressure of 28.97 MPa, 44.30 ◦ C temperature, and particle size of 0.54 mm. A crossover pressure point of Ben oil was found within the range 22.5–30 MPa|
