摘　　要：以马铃薯淀粉为原料,用次氯酸钠作氧化剂制备了氧化淀粉,研究了氧化剂用量、pH值、反应时间和温度对产品羧基含量的影响。结果表明:制备氧化淀粉最佳工艺条件为:氧化剂6%,pH7,反应时间4 h,温度35℃;以滴加方式加入次氯酸钠氧化效果较好.It was studied that the effect of the amount of oxidant, pH, reaction time and temperature on oxidation extent of potato starch adopted potato starch as raw material and sodium hypochlorite as oxidant. The results showed that the optimum processing techniques was 6 % of sodium hypochlorite,pH 7, reaction for 4 h at 35 ℃. A better oxidation could be obtained if sodium hypochlorite was added in instillation.
