The viscosity of a paste depends to a large extent on the degree of gelatinization of the starch granules and the rate of molecular breakdown. Viscosity parameters of Corn meal extrudates from particles of various sizes are shown in Table 4. High values of cold paste viscosity (MV25) indicates high shearing during the extrusion (Becker et al., 2001), which is translated into greater starch breakdown as more hydrophilic sites of the sheared starch molenetwork cules are exposed to water and forms a three-dimensional network at ambient temperature.
