Crystalline maltodextrin particles (CMPs) were investigated using polarization-sensitive second harmonic generation (PSHG) microscopy to determine changes in their crystalline organization due to crystal type (A- and B-type) and hydration for application as starch model systems. Optimization of their synthesis resulted in intense SHG emission, exceeding maize starch granules. PSHG data showed that CMPs have a radial macrostructure with respect to their nucleation regions, fitted values of 2-6, and some similar hydration variations, mimicking starch granules and validating that CMPs may be used as a model system for improved understanding of the SHG properties and applications of starch granules.
使用偏振敏感二次谐波产生（PSHG）显微镜对结晶麦芽糊精颗粒（CMPs）进行了研究，以确定由于晶体类型（A型和B型）和水合作用导致的其晶体结构变化，从而将其用作淀粉模型系统。对其合成的优化导致了强烈的二次谐波发射，超过了玉米淀粉颗粒。PSHG数据表明，CMPs相对于其成核区域具有径向宏观结构，拟合值为2-6，并且存在一些类似的水合变化，模拟了淀粉颗粒，并验证了CMPs可作为模型系统，用于更好地理解淀粉颗粒的二次谐波特性和应用。
