Abstract

The core objective of current research was determined to nutritional and bioactive profile of maize bran (MB)-enriched flour in relation to its end-use product quality. Furthermore, rheological properties of MB-enriched flour at different levels (5%, 10%, and 15%) were explicated through farinograph and mixograph. Moreover, bread was prepared with the addition of MB-enriched flour and was characterized for nutritional and textural properties. Results showed that MB-enriched flour having high water absorption and water retaining potential up to 4%-7% as compared to wheat flour (WF). Moreover, dough height gradually decreased with the addition of MB due to water-binding ability of bran which causes a decrease in gas retention during fermentation. This resulted in bread volume decrease (4%-7%) as compared to WF. Furthermore, the moisture content and hardness increased with the addition of MB. The water activity of bread slightly increased with the addition of maize bran after 4-day storage. Conclusively, MB-enriched flour improved nutritional, textural, and sensorial properties of final product.
