Supercritical carbon dioxide extraction is currently used in several food and pharmaceutical manufacturing applications. Its “greener” nature makes it a desirable option when compared with traditional organic solvent extractions. The purpose of this work is to compare the cost of using supercritical CO2 to commercially extract peanut oil with that of the traditional hexane extraction process. Solubility values of peanut oil in supercritical CO2 were also obtained under different conditions of temperature and pressure.
