不同温度下RAYBET雷竞技及时 结构的变化

淀粉是绿色植物通过光合作用产生的有机物质，可用于长期储能。 淀粉的结构比传统聚合物的结构复杂得多。 目前，关于淀粉微观结构的研究较少。 淀粉基聚合物的加工涉及多种化学和物理反应，包括水扩散、糊化、熔化和结晶。 一种重要的加工方法是淀粉的糊化。

Starch is an organic substance produced by green plants through photosynthesis, which can be used for long-term energy storage. The structure of starch is much more complex than that of traditional polymers. At present, there are few studies on the microstructure of starch. The processing of starch based polymers involves a variety of chemical and physical reactions, including water diffusion, gelatinization, melting and crystallization. An important processing method is gelatinization of starch.

随着温度升高， RAYBET雷竞技及时膨胀直至爆裂。 这种现象也发生在玉米淀粉的结晶区，随着温度的升高，结晶区逐渐减小并消失。 热台显微镜实验证实了这一观察结果。

With the increase of temperature, corn starch granules expanded until bursting. This phenomenon also occurs in the crystallization zone of corn starch. With the increase of temperature, the crystallization zone gradually decreases and disappears. This observation was confirmed by the hot table microscope experiment.

用激光共聚焦显微镜（CLSM）观察玉米淀粉的生长年轮发现，随着温度的升高，玉米淀粉的生长年轮逐渐从断裂，向全粒扩散。 GPC 测试有助于确定不同温度下玉米淀粉的分子量。 随着温度的升高，玉米淀粉的广度指数分布逐渐增大，直链淀粉和支链淀粉处于破碎状态。

Using laser confocal microscope (CLSM) to observe the growth rings of corn starch, it was found that with the increase of temperature, the growth rings of corn starch gradually broke from the center to the whole grain. GPC test is helpful to determine the molecular weight of corn starch at different temperatures. With the increase of temperature, the breadth index distribution of corn starch gradually increased, and amylose and amylopectin were in a broken state.
