| 摘 要： | 以膏状大豆磷脂为原料，用丙酮为溶剂制备了粉状磷脂。对萃取参数进行了优化，研究了洗涤次数，溶剂与膏状磷脂的比，丙酮中水的含量及萃取时的温度对粉状磷脂的纯度的影响。用正交设计优化工的萃取条件。在12℃，洗涤5次，膏状磷脂（g）：溶剂（ml）=30：250，萃取2min可得纯度为98．5％的粉状磷脂。

| Abstract: | The granule Soya lecithin was purified by deoiling with acetone from Soya wet gum. The extraction parameters were studied. The effect of washing times, ratio of wet gum and solvent, water content in acetone, extraction time and temperature on the purity of lecithin have been described. Through orthogonal design the optimum conditions were determined. Under the condition of using anhydrous acetone, Soya lecithin can be made into granule Soya lecithin, which acetone insoluble can reach 98.5%. |
