Light micrographs and SEM analyses showing starch granules morphology of control UT (A-C) and modified starches (D-I).
Starch granules were stained with a 20× diluted Lugol solution for light microscopy (A, D and G). Two different morphologies were observed in the modified starches from each series. Based on the colour of stained granules, the starches were classified into two categories: blue-stained group (D-F) and red-stained group (G-I).
