摘要: In order to confirm how Lactobacillus plantarum (Lp) and Pediococcus pentosaceus (Pp) regulate the flavor and microbial community in fermented soybean products. This study compared the microbial community structure, physicochemical properties, and flavor of four different beef-soybean pastes fermented with Lp, Pp, a mixed starter (Lp and Pp were mixed in a 1:1 volume ratio, Lp-Pp), and a control (non-inoculated lactic acid bacteria, CK) and analyzed the correlation between dominant microbial genera and critical volatile flavor compounds. The results showed that lactic acid bacteria inoculation fermentation (particularly in the Pp and Lp-Pp groupings) increased bacterial richness while reducing fungal abundance, and promoted the formation of critical flavor compounds. The benzaldehyde, furfural, and methional, were strongly (r > 0.731) positively correlated with dominant microbial genera Lactobacillus, Diutina, and Kodamaea. This confirmed our hypothesis that lactic acid bacteria inoculation promotes flavor development by altering the microbial community structure.
