Progress on characterization of starch granule morphology

Starch is a very important nutritive material,which is also an important industrial raw material. In the field of starch application,the processing and modification of the starch had been a research hotspot. In recent years,people carried out in-depth study of the structure and properties of modified starch,found that starch modification had a significant impact on the particle morphology,resulting in some changed in its performance. Therefore,before and after starch modification,characterization of the particle morphology was particularly critical. This article summarized and compared the current starch particle morphology characterization methods to help choose the correct method of characterization.
