中文摘要：

以稻米为原料，采用表面活性剂十二烷基磺酸钠降低稻米淀粉蛋白质含量。结果显示：提取稻米淀粉的最佳工艺条件是十二烷基磺酸钠质量分数为0．5％，液固比为1：6，浸泡时间为2h，蛋白质质量分数为0．5％，淀粉提取率为74.5％。

英文摘要：

The native rice protein content was reduced by surfactant sodium dodecanesulphonate （SDS）, The result showed that the optimum process conditions were surfaetant SDS concentration 0.5%, solid to liquid ratio 6：1 and soak time 2 h, The protein content in the rice starch was 0.5% and the extraction rate of starch was 74.5%.
