Regarding the effect of SS, it was found that all pasting properties of extruded flours decreased by 19.2–25.4%,
20.5–25.6%, 14.6–19.2%, 18.5–25.3%, and 8.8–12.9%, respectively when increasing SS. Obviously, higher starch degradation occurred due to higher shear forces at increased SS. Cool storage of the extruded flours significantly increased the pasting properties, especially peak viscosity.
