This study developed functional muffin by incorporating bioactive‐rich food materials into rice muffin formulation. Rice flour was progressively replaced with shiitake mushroom powder (MP) and carrot pomace powder (CP) and effects on pasting, physical and textural properties, as well as the antioxidant activity and consumer acceptability, were evaluated. The pasting properties of rice flour were significantly influenced (P < 0.05) by MP and CP incorporation. The additional increase in the levels of MP and CP decreased the volume of enriched muffins with a subsequent increase in weight and hardness. Higher polyphenol and carotenoid contents were observed in enriched muffins, exhibiting higher 2,2‐Diphenyl‐1‐picrylhydrazyl (DPPH) antioxidant activity compared to rice muffins. Sensory result revealed enriched muffins to have comparable and better consumer acceptability than rice muffin. Improvement in antioxidant properties of the developed functional rice muffins by MP and CP incorporation makes it a potential snack, suitable for consumption for its health benefits.
