high-temperature daqu, medium-temperature daqu, fungal communities, sensory quality, correlation analysis, Food processing and manufacture, TP368-456

To analyze the differences in fungal community structure and sensory quality of different types of Daqu in Binzhou, Shandong Province, the fungal community structure and quality characteristics of high-temperature and medium-temperature Daqu in Binzhou region were comprehensively analyzed by high-throughput sequencing, electronic nose and electronic tongue technology. The results showed that the diversity and richness of fungal species in high-temperature Daqu were significantly lower than those in medium-temperature Daqu (P0.05), but the difference in taste quality was significant (P0.05), but there was a significant correlation between the dominant fungal genera of Daqu and taste indexes (P
