Several studies have reported that starch pasting properties of noodle flour including peak viscosity, trough, and setback, provide crucial information for noodle manufacture, and some parameters are closely correlated with the quality of noodles. The values of peak viscosity, trough, and final viscosity are strongly associated with crystalline structure in starch granules and starch swelling properties. The reduction of starch pasting viscosities was partially caused by the increased damaged starch, because the millfeeds contained a small amount of flour so fine grinding of millfeeds could increase the damaged starch in the reconstituted WWF. Meanwhile, fine grinding treatment can also induce physical conversion of the starch granules resulting in a change of properties of starch similar to gelatinization. Therefore, it is probable that the crystalline region in starch granules of wheat coarse fraction was reduced and recrystallization among starch molecules was deteriorated after fine grinding, and these changes caused the decrease in the three values as grinding time increased. These results were in agreement with, who reported that the smaller the particle size of flour, the lower the RVA viscosity values.
