The maximum viscosity decreased with increases
in the moisture content of starches (18%, 21%, 24% and 27%) but variations were more evident for normal corn starch.
Significant decrease in paste viscosities of normal and waxy rice starches after heat treatment of starches with a moisture content of 20% at 140 C for 60 min was reported by
Anderson et al. (2002). Kweon et al. (2000)
