The normality dependence and the kinetics of flow behavior in the rice starch dispersion under strong alkali conditions were studied. Non-Newtonian flow (power-law) quantities n and μ(σ=μ(ε)n; σ: shear stress, ε: shear rate) of the samples stored (gelatinized) at 20∘C for 10min after the addition of NaOH solution with the normality 0.090 - 0.175N, were measured by a cone-plate type rotational viscometer. For the flow analysis a care was taken for the ambiguity of the analysis range of flow data. The samples added with 0.14 - 0.16N NaOH displayed an apparently dilatant flow. As the normality of added NaOH increased, apparent viscosity ηa was steeply enhanced in the vicinity of 0.14N and started to grow almost exponentially. Next, the storage time dependence of flow properties was investigated for samples gelatinized for 6
