The buckwheat flour slurry could be regarded as a dispersed systemconsisting a continuous phase of soluble populations of buckwheatcomponents and a dispersed phase of solid matters (Ye et al., 2016).Therefore, rheological property was one of the vital flow properties ofthe flour slurry, which played a key role in the wantuan processing.Fig. 4C showed shear stress versus shear rate for the slurries. The shearstress of the slurries increased as the increase of the shear rate. In rangeof shear rate (0.1–500 s− 1), the curve monotonically changed andplatform trends did not appear, indicating the absence of yield or plasticity in the slurry to some extent.
