Wheat bran and flour mixtures were used in a bread formulation to improve its quality characteristics. Wheat bran was microparticulated using a jet mill, and this microparticulated wheat bran (MWB) was substituted for a portion of wheat flour. As the MWB content increased, water-holding capacity, hardness and springiness increased while the swelling property decreased slightly. The hardness of bread containing MWB was lower than that made with commercial whole wheat flour (WWF). Bread containing 7% MWB had a higher specific volume (8.3%) than that of WWF bread. Enthalpy of dough decreased with increasing MWB content, and peak viscosity and breakdown decreased with increasing setback. Inner crust structures of bread containing MWB showed a slight reduction in gelatinization and gluten development in comparison with wheat bread. These results indicate that MWB could be used as a diet-enriching bread ingredient while maintaining bread quality.
