Deoiling of crude lecithin using supercritical carbon dioxide in the presence of co-solvents

Deoiling of crude soybean lecithin using supercritical fluid mixtures of carbon dioxide and 2 different co-solvents, ethanol and acetone, was studied at 62 degrees C and at pressures of 170 and 200 bars. Both ethanol and acetone increased the solubility of oil considerably without any significant coextraction of phospholipids. It was shown that deoiling could be achieved at lower pressures when a co-solvent is used leaving behind a valuable product of high content phospholipids, whereas negligible oil extraction was observed with pure CO2 at the same conditions.
