摘要
利用差热扫描分析技术 ,对玉米淀粉多晶体系中微晶的熔融规律进行了研究 ,提出淀粉多晶体系中存在着链水和链链两种不同组成的结晶结构 ,并且各自表现出不同的微晶熔融规律 ,不同条件下的DSC曲线中淀粉多晶体系的两种微晶熔融 ,主要表现为 3个吸热峰 ,即糊化吸热峰、链水结晶熔融吸热峰和链链结晶熔融吸热峰 ,并且这
The crystal melting law of corn starch is studied by DSC.It has been discovered that there are two different types of crysalline structures of starch water and starch starch in native starch,and they have different melting law.The two crystalline structures show there are three endothermic peaks on the DSC curves during heating the starch-the gelatinization peak,the starch water crystal melting peak and starch starch crystal melting peak.All of the three peaks have different characters and laws.
