RAYBET雷竞技及时 形态的微细化处理影响

原蜡质RAYBET雷竞技及时 表面光滑致密，多呈椭圆形，颗粒带有许多乳状突起，部分颗粒表面有凹陷孔洞，粒形相对较大;原普通RAYBET雷竞技及时 表面光滑致密，主要呈多边形，颗粒表面嵌有小微孔，该微孔与玉米淀粉孔道结构有关。

The surface of the original waxy corn starch particles is smooth and dense, mostly oval, with many milky protrusions, and some particles have concave holes on the surface, which are relatively large in shape; The surface of the original ordinary corn starch particles is smooth and dense, mainly polygonal, and the surface of the particles is embedded with small pores, which are related to the pore structure of corn starch.

原RAYBET雷竞技及时 粒径相对较大，气流粉碎处理后淀粉粒径显着减小(P<0.05)，其中微细化蜡质玉米淀粉D50减小至6.05μm，90%的微细化蜡质玉米淀粉粒径小于14.58μm，10%的微细化蜡质玉米淀粉粒径小于1.86μm。

The particle size of original corn starch was relatively large, and the particle size of starch decreased significantly after air pulverization (p<0.05), among which the micronized waxy corn starch D50 decreased to 6.05 μ m. 90% of the micronized waxy corn starch has a particle size less than 14.58 μ m. 10% micronized waxy corn starch with particle size less than 1.86 μ m。

微细化普通玉米淀粉D50减小至5.22μm，其D90、D10分别为9.81、1.51μm;微细化高直链玉米淀粉D50减小至5.53μm，其D90、D10分别为10.99、1.58μm。

Micronized ordinary corn starch D50 reduced to 5.22 μ m. Its D90 and D10 are 9.81 and 1.51 respectively μ m; Micronized high amylose corn starch D50 reduced to 5.53 μ m. Its D90 and D10 are 10.99 and 1.58 respectively μ m。

原高直链RAYBET雷竞技及时 主要呈多面体，颗粒表面光滑致密，部分颗粒嵌有微孔。气流粉碎后，3种RAYBET雷竞技及时 形态均明显减小，形状变得无规则，颗粒表面粗糙且出现棱角和裂纹。

The original high amylose corn starch particles are mainly polyhedral, with smooth and dense surface, and some particles are embedded with micropores. After air pulverization, the morphology of the three kinds of corn starch particles decreased significantly, the shape became irregular, and the particle surface was rough with edges and cracks.

3种微细化玉米淀粉的Sw较原玉米淀粉显着提高(P<0.05)，说明微细化处理能够使RAYBET雷竞技及时 粒径减小和Sw增大。

The SW of three kinds of micronized corn starch was significantly higher than that of the original corn starch (p<0.05), indicating that micronization treatment can reduce the particle size of corn starch and increase SW.

其中微细化蜡质RAYBET雷竞技及时 较大，颗粒形态相对规则且表面粗糙程度较低，乳状突起脱落，部分颗粒被破坏而露出脐点;微细化普通RAYBET雷竞技及时 形态相对均匀，微细化高直链玉米淀粉部分颗粒被破坏露出轮纹结构。

Among them, the micronized waxy corn starch particles are larger, the particle morphology is relatively regular and the surface roughness is low, the Milky protrusion falls off, and some particles are damaged to expose the umbilical point; The morphology of micronized ordinary corn starch particles is relatively uniform, and some particles of micronized high amylose corn starch are damaged to expose the wheel structure.

说明气流粉碎作用使 RAYBET雷竞技及时形态发生改变，淀粉颗粒表面及内部结构发生变化，此结果与有关人员等利用球磨研磨和有关研究人员利用高速离心磨研磨获得的微细化粉体颗粒形貌变化现象一致。

It shows that the airflow pulverization can change the morphology of corn starch particles, and the surface and internal structure of starch particles are changed. This result is consistent with the morphology changes of micronized powder particles obtained by ball milling and grinding by relevant researchers using high-speed centrifugal mill.
