Optimization of Supercritical CO₂ Extraction of Noni (Morinda citrifolia L) Seed Oil Using Response Surface Methodology

Abstract:

This study examined extraction of noni (Morinda citrifolia L) seed oil（NSO） by using supercritical carbon dioxide (SC-CO₂). Response surface methodology (RSM) was used to evaluate the effects of the process parameters, namely extraction pressure, temperature and CO2 flow rate and extract time on the yield of NSO. The extraction parameters were optimized with a central composite design experiment. The result showed that the oil recovery got the highest for 20.13% dry basis under the condition of pressure 21 MPa, temperature 37°C, flow velocity 20 L/min and the extract time 104 min, the pressure expressed most significant effect on the oil yield (p <0.001)
