Description Sova lecithin, de-oiled by supercritical carbon dioxide extraction at 200 bar and 50°C, was subjected to ethanol extraction for the enrichment o f phosphatidylcholines (PC). Tire process variables time, temperature and ethanol-lecithin ratio were studied for optimization o f PC enrichment bv response surface methodology following a Box-Behnken design of experiments. An optimum value o f PC enrichment was not found. However, the results indicated: (a) PC enrichment generally increased with an increase in all three variables. (b) Until 5 min extraction time, there is no significant increase in PC enrichment. (c) Above an ethanol-lecithin ratio o f 50 L/kg, not much increase in PC enrichment was noticed. (d) A rise in the temperature o f extraction leads to increase in PC enrichment.
