摘　　要：研究了超临界CO2 萃取技术从大豆浓缩磷脂中去油 ,制取高纯度大豆磷脂。产品的丙酮不溶物 (AI)达 96 %以上 ,色泽微黄、无溶剂残留。研究了在较低萃取工艺条件 (2 5MPa～ 35MPa ,35℃～ 5 5℃ )下达到实验目的可能性 ,并研究了两步萃取法制备高纯度磷脂的新工艺 ,探讨了萃取温度、压力、时间和进料量对产品纯度的影响 。A new process of deoiling soy lecithin with supercritical fluids CO 2 was investigated in this study.A light yellow color,without solvent residual product was obtained.This powder produc contained over 96% AI,The possibility to achieve the objectives of experiments under a lower condition (25—35mpa,35-55℃)was studied.A new two step PL extraction process of flaking was developcd.This study also examined the effecls of temperature,pressure,time and amount of feed matcrial on the conccntration of PL,and got economic process paramelers.
