Abstract Edible mushrooms contain a variety of bioactive molecules that may enhance human health and wellbeing. Consequently, there is increasing interest in fortifying functional foods with these nutraceutical‐rich substances. However, incorporation of mushroom‐based ingredients into foods should not adversely affect the quality attributes of the final product. In this study, the impact of incorporating powdered Auricularia auricula , a widely consumed edible mushroom, into bread products was examined. The rheological and structural properties of wheat dough and bread supplemented with 0% to 10% (w/w) A. auricula flour were measured. Supplementation of wheat doughs with A. auricula flour increased the peak viscosity and enhanced their water holding capacity. Rapid viscosity analysis showed that peak and final viscosities of the blended flour (wheat flour with A. auricula flour) were higher than wheat flour alone. However, dough stability and elastic modulus were reduced by blending wheat flour with A. auricula flour. SEM observation showed that doughs with up to 5% (w/w) A. auricula flour had acceptable gluten network microstructure. Characterization of the quality attributes of bread indicated that incorporation of A. auricula flour at levels >5% negatively impacted bread volume, height, texture, and appearance.
