摘　　要：以低PC含量大豆粉末磷脂为原料,在单因素实验基础上利用正交实验对磷脂脱糖工艺进行优化。研究结果表明,最佳工艺条件为:温度为30℃、时间为70 min、V(正己烷)∶V(乙醇)为1∶2、乙醇体积分数为50%、萃取次数为2次,此时脱糖率为89.7%,粗糖中糖的含量为89.2%。利用高效液相色谱法对提取的糖种类进行鉴定,结果表明这些糖为水苏糖、蔗糖、棉籽糖,其含量分别为71.1%、17.3%、6.6%。Using powered soybean phospholipid with low PC content as raw material,the process of desugarization was optimized by the orthogonal experiment based on the single factor experiment. The results showed that the desugaring rate arrived 89. 7% and the content of sugars in the extractive raw sugar was89. 2% when the optimum parameters were chosen as follows ： temperature 30 ℃,extractive time 70 min,volume ratio of hexane to ethanol 1∶ 2,volume fraction of ethanol 50% and extraction for twice. The kinds of the removed carbohydrates and its content were determined by high performance liquid chromatography,which were stachyose,sucrose and raffinose,with contents of 71. 1%,17. 3%,6. 6%,respectively.
