Apart from Yanlong starch, OD and ED starches presented similar digestion patterns. Oven- and ethanol-drying were shown not to significantly affect the digestion properties of starches, but freeze drying led to a significant increase in the digestion rate of potato starch. In the present study, freeze drying disrupted the crystalline structure of chestnut starches and oven drying led to the pores and cracks on the surface of granules, which were assumed to increase the hydrolysis percentage of FD and OD starches.
