Nowadays the nutritional specifications of wheat bread have been more considered, this purpose would have done by mixing different materials with wheat flour. The bran is one of the materials that had more been considered by researchers, due to its nutritional and technological properties. Therefore, in current research, the effects of adding different percentages of bran (10 and 20 percent) with different particle sizes (tiny and coarse) on the sangak bread was evaluated. The rheological properties of dough investigated by the farinograph and extensograph and textural properties of bread analyzed using texture analyzer. The results revealed that adding wheat bran resulted a decrease in weight loss and an increase in moisture content of sangak bread. Adding wheat bran increased the water absorption capacity up to 11.35%. The elasticity of dough in samples containing wheat bran varied from 74.87 to 112.62. Dough samples made from whole flour had the highest amount of consistency with 337.5 BE in 50mm. Hardness of bread with 20 percent of tiny bran was 4132g that was the highest comparing with other sangak bread samples. Sensory scores showed that sangak bread made from flour formulated with wheat bran have not been taken into consideration by the panelists group, although adding wheat bran due to better technological properties.
