Abstract: The experiment included testing of rheological properties of dough as well as the baking quality of bread flour and bran obtained by grinding coloured wheat grains with purple pericarp (cultivars Rosso, Konini and PS Karkulka) and blue aleurone (cv. Scorpion). Common wheat cv. Mulan was used for comparison. Formulas containing 10, 15 and 20% of bran were prepared. The addition of bran increased the water loss during baking by an average of 1.28%, specific volume of bread decreased by 2 to 10 mL, and the ratio number decreased from 0.57 to 0.51. The dynamic oscillatory rheometry simulated processes occurring during baking. A higher content of bran increased the complex viscosity of dough. In the initial stages of heating, the increasing presence of bran promoted dough weakening. Starch gelatinization was also influenced by the content of bran.
