Abstract :In this study, different muffin samples were produced by substituting 0, 5, and 10% (w:w) hazelnut shell powder (HSP) into wheat flour and their color, bioactive, textural and sensory properties were determined. The results showed that both total phenolic content and DPPH radical scavenging activity did not change with the addition of HSP to the muffin formulation. Upon enrichment of muffins with HSP, L* and b* color values of muffins decreased in both crumb and crust, while a* values increased in crumb and decreased in crust. The more HSP used in the muffins, the more visible pore formation was determined. Textural analysis revealed that hardness, gumminess, chewiness values decreased while the springiness, cohesiveness and resilience values increased as the amount of HSP increased in the muffin formulation. The partial substitution of wheat flour with 5% (w:w) HSP received the highest crust, crumb, chewiness, taste/aroma and overall acceptability scores by the panelists. Overall, HSPs, which are a waste and by-product of hazelnut processing, can be successfully used in fiber-rich muffin production, both expanding their potential areas of use and contributing to their economic value.
