研究了不同种类苦荞淀粉的性质。采用扫描电镜(SEM)拍摄了苦荞淀粉颗粒的形态;用X-射线衍射仪测定了X衍射图样及结晶结构;用快速黏度分析仪(RVA3)对各个淀粉黏度进行了测定;并与玉米淀粉进行了比较。同时测定了淀粉糊的透明度、凝沉曲线等性质。

The physical and chemical properties of different kinds of tartary buckwheat starches were studied.The granule morphology,X-ray diffraction pattern and paste viscosity of different tartary buckwheat starches compared with maize starch were analyzed by SEM,X-ray diffraction and RVA3 respectively.Also,the transparency,gelatinization and other properties of the starches were studied.It provided some basis theory for guiding development and further research of tartary buckwheat starch.
