To systematically explore the impact of microbial community composition on the quality characteristics of northeast soybean paste, the microbial community structure was determined by high-throughput sequencing technol. and the flavor substance, free amino acid (FAA) and biogenic amine (BA) contents were determined by HS-SPME-GC-MS and HPLC. Furthermore, the correlation between microorganisms and metabolites was investigated. The results indicated that the core bacteria mainly included Tetragenococcus, Bacillus and Lactobacillus; Candida_f__norank, Wickerhamomyces and Aspergillus were the dominant fungi. A total of 139 flavor compounds were detected in all samples, and decamethylcyclopentasiloxane, isoamyl phenylacetate and octamethylcyclotetrasiloxane accounted for the highest proportion. A total of 24 FAAs were detected in the soybean paste. Pantoea, Kroppenstedtia and Kocuria were significantly pos. correlated with most FAAs (p < 0.05). Addnl. 5 BAs were detected in the soybean paste, and the contents of BAs in Y4 were highest, which was affected by different microbes. This study provided relevant information for the microbial community composition and metabolites of northeast soybean paste, which was of great significance for understanding the characteristics and safety of soybean paste. In the experiment, the researchers used many compounds, for example, Methyl2-methylbutyrate (cas: 868-57-5Category: esters-buliding-blocks).
Methyl2-methylbutyrate (cas: 868-57-5) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Category: esters-buliding-blocks
