Rheological properties of α-rice powder were investigated in comparison with those of polished rice powder. Flow behavior for cooked solutions of two powdered samples(5∼11%) were Binghampseudo plastic. Consistency index and yield stress of cooked solution of powdered α-rice were much lower than those of polished rice powder while flow behavior index was nearly similar. 9% cooked solution of powdered a -rice showed slightly weaker thixotrophic behavior and more ease tendency to relax under the steady shear than those of polished rice powder.
