As the reaction time increased from

As the reaction time increased from 7.5 min to 120 min, the pasting temperature of modified rice starches was gradually decreaed to the lowest pasting temperature at 120 min.The peak viscosity of modified rice starches were lower than that of the native rice starch when the modification time was shorter than 30 min, but the peak viscosity of modified starch was higher than that of the native rice starch when the reaction time was longer i.e., 60 min
