Fortification of Chinese Steamed Bread Through Broken Ganoderma lucidum Spore Powder Incorporation: Effects on...

Broken Ganoderma lucidum spore powder (BGLSP) is abundant in nutrients and bioactive compounds, rendering it a suitable functional raw material for food applications. This study examined the impact of incorporating BGLSP (ranging from 0.5% to 10%) on the physicochemical properties of flour blends, dough, and the quality of Chinese steamed bread (CSB). The results indicated that with increasing BGLSP content, the a* value, onset temperature, peak temperature, water absorption, development time, and dough stability all exhibited an upward trend in the flour blends and dough, while the L* value and protein network weakening decreased. When compared to the control sample, the inclusion of 10% BGLSP resulted in a reduction in the spread ratio, specific volume, cohesiveness, and springiness of CSB, while simultaneously increasing its hardness, chewiness, and gumminess. The observed odor variations among samples were primarily ascribed to the proportions of aldehydes and ketones. Notably, sensory evaluation demonstrated that the flavor attributes of BGLSP-enhanced samples were superior to those of the control sample. In conclusion, the incorporation of BGLSP at concentrations ranging from 0.5% to 1% is deemed optimal for CSB, offering novel insights into the application of BGLSP within the food industry.
