| 中文摘要: |
| 以大豆粉末磷脂为原料，建立了以乙醇溶液为溶剂的单溶剂体系脱糖方法。考察了脱糖过程中乙醇体积分数、脱糖温度、料液比、脱糖时间、脱糖次数对脱糖率的影响，并通过正交试验对脱糖条件进行优化。最终得到最佳脱糖条件为乙醇体积分数55%、脱糖温度30?℃、料液比1∶?8、脱糖时间50 min、脱糖次数1次。在最佳条件下，大豆粉末磷脂脱糖率达90.64%。采用HPLC对所得糖类物质进行了鉴定，结果表明其主要是由蔗糖、棉子糖和水苏糖组成，含量分别为11.87%、8.84%、75.16%。这3种糖与大豆低聚糖主要成分一致。 |

| With soybean powder phospholipid as raw material， a removal method of carbohydrates in single solvent system of ethanol solution was established. The impacts of volume fraction of ethanol， removal temperature， ratio of material to liquid， removal time and removal times on removal rate of carbohydrates were studied， and the removal conditions of carbohydrates were optimized by orthogonal experiment. The results showed that the optimal removal conditions of carbohydrates were obtained as follows：volume fraction of ethanol 55%， removal temperature 30?℃， ratio of material to liquid 1∶?8， removal time 50 min and removal times once. Under the optimal conditions， the removal rate of carbohydrates from soybean powder phospholipid was 90.64%. The identification result of HPLC turned out that the removed carbohydrates were mainly composed of sucrose， raffinose and stachyose. Their contents were 11.87%， 8.84% and 75.16% respectively. The three main carbohydrates were consistent with soybean oligosaccharides. |
