| Abstract: | Soybean phospolipid of 98% purity was extracted by the supercritical fluid extraction (SFE) from crude soybean phospolipid.Effects of pressure,temperature and operation time on the extraction yield were studied too.Temperature was the most remarkable in three factors.Time was more remarkable than pressure.The optimized technological conditions were:pressure 20 MPa,temperature 50 ℃ and time 5 h. |
