Comparative evaluation of the effects of natural and artificial inoculation on soybean paste fermentation was written by Zhang, Xiao;Shan, Tingting;Jia, Hang;Guo, Chunfeng;Wang, Zhouli;Yue, Tianli;Yuan, Yahong. And the article was included in LWT–Food Science and Technology in 2022.Synthetic Route of C6H12O2 This article mentions the following:
Soybean pastes fermented with natural (NIS) and artificial (AIS) inoculation were prepared to evaluate their fermentation characteristics, flavor compounds and microbial community compositions across an entire fermentation period. The results showed that the initial concentrations of free amino acids and aroma compounds were higher in NIS than in AIS, whereas it was opposite at the end of fermentation A larger variation of flavor compounds was observed in AIS, which was associated with higher level of microbial metabolism during AIS fermentation Penicillium and Tetragenococcus were the dominant microbial genera in NIS, while Aspergillus and Pediococcus were predominant in AIS. Correlation anal. of flavor compounds and microbial community dynamics during NIS and AIS fermentation revealed the specific role of microbial taxa in metabolite transformations. Pediococcus acidilactici could be the key microorganism strongly associated with 23 flavor compounds during AIS fermentation Further, Aspergillus oryzae and Pediococcus acidilactici were primarily linked to amino acid metabolism in AIS, whereas Penicillium and Yaniella were found associated with aroma compounds, Tetragenococcus_sp_JNURIC_D6 and Candida solani with that of organic acids in NIS. These findings provide substantial data on the development of flavor-enhancing fermentation starter culture and the better control of flavor ripening in soybean paste production In the experiment, the researchers used many compounds, for example, Methyl2-methylbutyrate (cas: 868-57-5Synthetic Route of C6H12O2).
Methyl2-methylbutyrate (cas: 868-57-5) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. 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.Synthetic Route of C6H12O2
