Supercritical CO2 (SC-CO2) extraction has been an excellent
alternative method for seed oil extraction to replace conventional
industrial methods. SC-CO2 extraction becomes the focus of attention
due to its chemical and physical properties: non-flammable,
non-toxic, non-corrosive etc. Furthermore, the extracted product
has a good quality and scarcely needs any particular refining operation.
Thus, SC-CO2 technology has been applied to the extraction of oil from a large number of materials over the last twenty years
and shows a bright future (Reverchon and Marrone, 2001).
