Abstract:
      The sesame phospholipids concentrate was defatted by acetone to obtain sesame phospholipids powder, then lecithin (phosphatidyl cholines(PC))was separated from the sesame phospholipids powder by ethanol extraction method. The optimal extraction conditions were obtained by single factor experiment and orthogonal experiment as follows: ethanol volume fraction 95%, solid-liquid ratio 1∶12, extraction temperature 50℃, extraction time 20 min.Under the optimal conditions, the extraction rate of lecithin was 27.92%, and the content of PC in lecithin was 53.31%.
