摘　　要：研究了肌醇磷脂(PI)含量为30%～75%的大豆磷脂的润湿性能、乳化性能和界面张力,并与粉状大豆磷脂表面活性进行了比较。PI含量为50%的大豆磷脂的润湿性能优于PI含量低于50%的大豆磷脂的润湿性。随着PI含量的增加,大豆磷脂对石蜡、柴油、豆油及苯的乳化性能逐渐增强;当PI含量为75%时,其乳化能力接近OP(壬基酚聚氧乙烯醚)。不同组分的大豆磷脂的界面张力不同。高卵磷脂含量(72%)的大豆磷脂的界面张力降低值低于高PI含量(50%)的大豆磷脂。The wetting ability, emulsifying ability and interfacial tension of the phosphatiylinositol which the content of was 30%-75% were studied. The wetting ability of PI with 50% content was superior to other PI with lower content. With increasing of the content of PI, the emulsifying ability to paraffin, dissel, soybean oil and benzene was increasing. The emulsifying ability of PI with 75% content was closer to OP. Different content soya phospholipids had different interracial tension. The interfacial tension of PI with 72% was lower to other PI with 50%.
