Noodle is one of the most important parts in the diet of Asian people. It has also become popular in many countries outside of Asia. the development of noodles made from wheat bran and whole-wheat flour with high content of dietary fiber should be an effectiveway to promote high fiber food consumption and change the dietary pattern of many consumers. Therefore, the objective of this seminar is to investigate the effects of particle size and addition level of wheat bran and whole wheat flour on the quality of noodle. The study of addition level and particle size of wheat bran affected the mixing characteristics and pasting properties of noodle flour. Addition of wheat bran significantly decreased the peak viscosity, final viscosity, breakdown, and setback of blends. Coarse bran or high addition levels affected the breaking strength and flexibility of dry noodles. The study Compared to coarse particles, millfeeds with finer particles exerted beneficial effect on the quality improvement of whole wheat raw noodles.
