Starches subjected to freeze- and oven-drying treatments were
hydrolyzed more greatly compared with ED starch. 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 (Zhang
et al., 2014). 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.
