| 摘 要： | 研究了玉米淀粉糊在加热干燥制成预糊化淀粉的过程中，X射线衍射曲线的变化规律。结果表明在加热干燥过程中。会随着水份含量的减少而逐渐形成大量的微晶结构。预糊化淀粉的X射线衍射曲线是由一个弥散的结晶衍射峰和一个弥散的非晶衍射峰组合而成的。

| Abstract: | In the course of corn starch being pregelatinied by heating and drying, the law of change of X ray diffraction pattern is studied. The results indicate that a large quantities of microcrystals are formed with the reduction of moisture content and that the X ray diffraction pattern of pregelatinized starch is a combination of an unsharp crystalline and an unsharp noncrystalline diffraction peak. |
