| 摘 要： | 将非晶颗粒态淀粉和原淀粉在阴、阳离子醚化剂条件下进行淀粉改性反应,取代度随醚化剂量的改变而改变,但由于整个颗粒处于非晶状态,导致非晶淀粉取代度和原淀粉相比有不同程度的提高:对羧甲基化,取代度平均提高13.03%,最高提高18.51%;对阳离子化来说,取代度平均提高13.29%,最高提高16.39%。在不同反应时间进行反应,也可以观察到相同的变化规律,因此将淀粉进行非晶化可显著提高淀粉的反应取代度,最终提高反应效率。

| Abstract: | Non-crystallized and native corn starches were carbonxymethylied and cationizatied respectively, DS changed with amount of etherified reagent. Because of whole granules being non-crystallized state, DS of non-crystallized starches was higher than that of native starches. When corn starch was carbonxymethylied, DS of starches increased 13.03% average, 18.51% most. While cationizatied, DS of starches increased 13.29% average, 16.39% most. In different time, the same change rule can be observed. Therefore, DS of corn starches would be increased by being non-crystallized and reaction efficiency was also increased. |
