Nutritional Composition, Physicochemical Properties, Antioxidant Activity, and Sensory Quality of Matricaria chamomilla-Enriched Wheat Bread

This study evaluates the effects of fortifying bread with different concentrations (3%, 10%, and 30%) of Matricaria chamomilla L. (MC) infusion and powder, derived from the plant’s aerial parts (stem, leaf, and flower). UPLC/MS-MS analysis of MC infusion and powder ethanolic extract confirmed the presence of polyphenolic compounds, including flavonoids, contributing to enhanced antioxidant and enzyme inhibitory properties. The physicochemical, antioxidant, and sensory properties of the enriched breads were assessed. Hierarchical cluster analysis revealed that breads enriched with 30% MC powder (BP-MC 30%) and infusion (BI-MC 30%) exhibited superior overall quality compared with other formulations. The enriched breads showed increased protein, fiber, and antioxidant content. Specifically, BI-MC 30% demonstrated superior antioxidant activity, while BP-MC 30% provided the highest fiber content. Sensory evaluation indicated that the enriched breads retained sensory properties similar to those of the control bread, despite the nutritional improvements. These findings suggest that incorporating Matricaria chamomilla, particularly at 30%, enhances the nutritional profile and antioxidant properties of bread while maintaining sensory characteristics close to those of traditional bread. This research highlights the potential of using chamomile’s aerial parts in the valorization of plant-based by-products for functional bakery product development.
