| 摘 要： | 用NaOH溶液浸泡米粉去除蛋白质提取大米淀粉的试验结果表明,在0.2%NaOH溶液、固液比1:4、浸泡2h的最佳提取条件下,淀粉中的蛋白质含量为0.453%、淀粉得率为74.2%。采用快速粘度分析仪测定以烘箱法和真空冷冻干燥法所得淀粉的黏滞性谱,结果显示两种淀粉的黏滞性有一定差异。 |

| Abstract: | The extraction of starch from rice was studied by NaOH method.In the method the optimum conditions were NaOH amount 0.2%,time 2h and the ratio of solid and fluid 1:4.The results showed that the extraction rate of protein was(0.453%) and the content of starch was 74.2%.By Rapid Visco Analyzer(RVA),the starch viscosity properties with two different dryness method were analyzed.And the results showed that there are some difference among them with the viscosity property. |
| Keywords: | rice starch extraction viscosity property |
