The effects of medicinal mushroom (Sparassis crispa) powder supplementation on the rheological property of dough and the quality of bread were investigated. Naturally dried S. crispa powders (NDSCP) and freeze-dried ones (FDSCP) were prepared. Farinograph profiles of dough showed that mushroom powder addition at levels higher than 1% led to reduced dough stability suggested by decreased development time and increased weakness. The incorporation of S. crispa powders was significantly (p<0.05) lower compared to other mushrooms which might be attributed to its high content of beta-glucan. FDSCP was chosen over NDSCP because of its fragrant flavor which could be ascribed to the preservation of volatile polyphenol components. The quality of FDSCP bread was evaluated with respect to specific volume, texture, color, and organoleptic qualities. The specific volume of bread with S. crispa powder decreased compared to the control, while textural properties, such as hardness, chewiness, and gumminess, were enhanced. Sensory evaluation showed that 0.3% FDSCP incorporation presented the highest bread quality. With its daily consumption, S. crispa supplemented bread can provide consumers with multiple health benefits.
