Effects of superfine grinding on the quality characteristics of WWF and its raw noodle product were investigated in the study. Four particle distributions were obtained by superfine grinding. Both The peak viscosity, trough, and final viscosity decreased as WWF particle size reduced. The color, cohesiveness of WWN were improved by the superfine grinding process. Although excessive starch damage produced by the superfine grinding process exerted some adverse effects on the properties of WWN, the results of the study demonstrated that superfine grinding effectively reduced the particle size of WWF and enhanced the quality characteristics of WWN.
