| 摘 要： | 利用电子扫描、Ｘ射线衍射和偏光显微等现代分析技术，研究了羧甲基变性对淀粉颗粒形貌和结晶结构的影响。结果表明，羧甲基化反应既发生在淀粉颗粒结构的无定形区，也发生在结晶区，从而使结晶程度降低，结晶区域变小。同时，淀粉的颗粒表面也出现裂纹和洞穴。这些结构上的变化是导致淀粉性质发生变化的原因。

| Abstract: | The effect of carboxymethylation on the particle morpha and crystalline structure of starch granules has been analyzed by using the modern analytical techniques such as electron scan,X ray diffraction and polaroid microscopy etc in the experiment.The results showed that the carboxymethylation occurred not only in the amorphous regions but also in the crystalline regions,at the same time caves and/or cracks appeared on the surfaces of granules.The changes in the morphology and crystalline structure of starch granules result in the variation of starch properties after carboxymethylation. |
