Amylolytic susceptibility of a native varagu starch granule was followed chemically and microscopically. Scanning electron microscopy revealed that attack by salivary α‐amylase resulted in a gradual erosion of the surface followed by granule penetration at certain locations. Attack by glucoamylase, on the other hand, was more uniform, and resulted in pitting and depressions all over the surface.
