The effects of operating pressures and temperatures on the solubilities of acylglycerols and free fatty acids (FFA) of palm oil (Elaeis guineensis) in supercritical carbon dioxide (SC-CO2) were determined using a dynamic (flow-through) supercritical fluid extraction system. The solubility of palm oil was also investigated. The experiments were carried out in a 3 X 3 factorial design with three equally spaced pressures (14, 22 and 30 MPa) and three equally spaced temperatures (40, 60 and 80°C). The solubilities (mg/g CO2) of acylglycerols and FFA followed this order: TAG > FFA > DAG > MAG for high pressure. However, highest solubility of FFA was observed at low pressure. The results showed that the solubility of palm oil in SC-CO2 was in the range of 0.1751 ± 0.0007 to 6.60 ± 0.03 mg/g for the conditions studied. The solubility of palm oil in SC-CO2 is significantly influenced by the solubilities of acylglycerols and FFA. The optimum condition for maximum solubility of palm oil was found to be at 60°C and 30 MPa. The experimental data obtained for the palm oil solubility was compared with other vegetable oils and correlated by the improved density-based equation proposed by del Valle-Aguilera.

Supercritical Carbon

A significant quantity of tocochromanols and carotenoids remains in the residual from palm oil production by traditional screw pressing. Supercritical carbon dioxide extraction was used as alternative method with the purpose to recover better these valuable minor compounds. Total oil yield and co-extracted water were investigated in the course of extraction. Tocochromanols and carotenoids were evaluated, not only in the extraction oil, but also in the oil of residual fibre. Modelling of extraction process was also performed for a further up-scaling. The results showed that oil yield up to 90% could be observed within 120 min. Supercritical carbon dioxide (SCCO2) could extract tocochromanols and carotenoids with concentration in the same range of normal commercial processing palm oil, while co-extracted water remained rather low at a level of 2–4%. Moreover, recovery efficiencies of these minor compounds were much higher in case of extraction processed with supercritical carbon dioxide than those with screw pressing method.
