Bran characteristics impact the whole wheat noodle quality

Abstract

In this study, whole wheat flour (WWF) was prepared by blending one commercial noodle flour with ten different bran samples from white and red winter wheat varieties. The whole wheat dough properties and noodle qualities were investigated. In general, brans from red wheat varieties exhibited higher total phenolic contents than those from white wheat varieties. Mixolab analysis revealed significant relationships between bran ash, starch, and insoluble dietary fiber (IDF) contents and the mixing and pasting properties of WWF dough. Concerning the noodle quality, bran protein content showed a positive correlation with tensile strength (P < 0.01), elongation distance, springiness, and resilience of cooked noodles. Also, bran IDF content was positively related to the hardness of cooked whole-wheat noodles. These results suggest that bran with higher protein content and lower IDF content is more desirable for the production of whole wheat noodles.
