The creep behaviours of "Dangos", which were prepared with various particle size of non-glutinous and glutinous rice powders and were stored at 25℃ for 50 hrs, were measured with different periods of storage time. The changes in creep compliance of "Dango" with storage time could be expressed by the first-order kinetic equation, hence the retrogradation process of "Dango" was regarded as monomorphic. The values of initial creep compliances, J_0, for "Dango" prepared with non-glutinous rice powder decreased, while the rate constants, k, increased with decreasing particle size of rice powder. In the case of "Dango" prepared with glutinous rice powder, the values of J_0 decreased with decreasing particle size of powder, while k showed the max imum value when "Dango" was prepared with 150-200 mesh powder. "Dango" prepared with glutinous rice powder was softer than that with non-glutinous one in the initial stage of storage. However, the rate constant of "Dango" prepared with glutinous rice powder showed the greater values than that with non-glutinous one. It may correspond that retrogradation process of glutinous "Dango" was facilitate compared with non-glutinous one.
