Note: CS, native chestnut starch; CT-3, CT-6, CT-9, CT-12, preparation of chestnut starch by continuous dry heat treatment for 3 h, 6 h, 9 h, 12 h, respectively; RT-2, RT-3, RT-4, preparation of chestnut starch by repeated dry heat treatment for two cycles, three cycles, four cycles, respectively. Results are showed as mean values ± SD in triplicate. Different letters in the same column show a significant difference at p < 0.05.
