摘要
运用广角X射线衍射分析技术 ,对不同水分含量的原玉米淀粉颗粒微晶结构进行了研究 .提出在玉米淀粉颗粒的多晶体系中存在着链链和链水两种不同组成和性质的结晶结构 ,不同的水分含量对它们有不同的影响 .另外 ,还发现悬浮在常温水分散体系中的淀粉颗粒 ,尽管只发生轻度的溶胀 ,但淀粉颗粒原有的结晶结构已受到很大程度的破坏 .
The influence of different water content on crystalline structure of native corn starch is studied by the examimation methods of X ray Wide angle Scattering. It has been discovered that there are two kinds of crystals in the native corn starch granules,they have different basic crystalline values and different peak on the X ray Diffraction Pattern. It has been also found that the crystalline structure of starch granules is damaged sharply by suspending in the water at the normal temperature.
