Abstract

Solubility of soy lecithin lipids in supercritical CO2 was measured at pressures of 120, 200 and 280 bar and at temp. of 40, 50 and 60C. Effects of temp. and pressure on solubility of total lipids were studied by response surface methodology. The response surface equation to predict solubility of total lipids in the above range of pressure and temp. is: Y = -3.237 + 0.0431*P - 7.3 x 10-5 P2 - 0.00011 P*T, where Y is the total lipid solubility in g/kg CO2, P is the pressure in bar and T is the temp. in C. Total lipids solubility increased with pressure at constant temp., but decreased with increasing temp. The total lipids consisted of a low level of phospholipids compared to neutral lipids and glycolipids at all the pressures and temp. studied. Max. solubility of total lipids was found at 1.829 g/kg CO2 at 263 bar and 40C.
