An attempt is made in this study to balance the nutritional and sensory quality of bread. In particular, the formulation of a functional durum wheat bread enriched with bran at high concentration has been developed. Organogel concentration and bran particle size have been used as process variables for bread optimization. Bran concentration was increased at value as high as 15%, thus increasing the nutritional content, even though the sensory quality decreased. Bread was scored barely acceptable at 15% bran concentration. Therefore, the organogel concentration and bran particle size have been optimized to enhance bread sensory quality. Results show that it is possible to prepare bread with a significant bran enrichment without compromising its acceptability by adding proper concentration of organogel and using bran in appropriate particles size.
