Different physicochemical properties of entirely α-glucan-coated starch from various botanical sources.

Unlabelled: Amylosucrase from (AS) synthesizes α-1,4 glucan polymer from sucrose. In this study, we coated various botanical sources of raw starch with an α-glucan layer generated by AS to improve physicochemical properties. Field-emission scanning electron microscopy demonstrated that all surfaces of the starch granules were successfully coated via the AS reaction.
