Characteristics and Correlation of the Microbial Communities and Flavor Compounds during the First Three Rounds of Fermentation in Chinese Sauce-Flavor Baijiu

Foods, Journal Year: 2023, Volume and Issue: 12(1), P. 207 - 207

Published: Jan. 3, 2023

Sauce-flavor Baijiu is representative of solid-state fermented Baijiu. It significant to deeply reveal the dynamic changes microorganisms in manufacturing process and their impact on formation flavor chemicals correlated with quality can be divided into seven rounds, from which kinds base Baijius are produced. The third round significantly better than that first second but mystery behind phenomenon has not yet been revealed. Based high-throughput sequencing analysis grains, correlation analysis, concentrations grains were enhanced, including esters hexanoic acid, ethyl ester; octanoic decanoic dodecanoic phenylacetic 3-(methylthio)-propionic acid acetic phenylethyl butyl ester, other closely related sauce-flavor Baijiu, such as tetramethylpyrazine. should an important reason for improvement Correlation showed ester synthesis was promoted by bacteria genus

Comparative Analysis of Physicochemical Properties and Microbial Composition in High-Temperature Daqu With Different Colors

Frontiers in Microbiology, Journal Year: 2020, Volume and Issue: 11

Published: Nov. 27, 2020

High-temperature Daqu , also called Jiang-flavor is the saccharifying and fermenting agent for brewing Baijiu. During spontaneous solid-state fermentation of high-temperature variations in temperature moisture lead to microbial diversity various metabolites, contributing different colors (customarily referred as white black yellow red production). We aimed investigate differences communities, physicochemical indices, potential functions among with (labeled QW, QB, QY, QR) by amplicon sequencing. found that Kroppenstedtia Bacillus Thermoascus were predominant all samples; Saccharopolyspora Thermomyces QB QR; Unclassfied_O_Eurotiales QY. The results on characteristics indicated compared other samples, QW exhibited higher protease activity lower acidity, whereas showed opposite results. QR had highest esterification yield, QY saccharification but lowest yield. Functional prediction demonstrated abundances genes encoding bacterial enzymes related considerably (59%) (87%), respectively. abundance (80%) contributed fungal QB. This study revealed functional dissimilarities color-based starters helped facilitate liquor process.

A Bottom-Up Approach To Develop a Synthetic Microbial Community Model: Application for Efficient Reduced-Salt Broad Bean Paste Fermentation

Applied and Environmental Microbiology, Journal Year: 2020, Volume and Issue: 86(12)

Published: April 17, 2020

Humans have mastered high-salinity fermentation techniques for bean-based fermented product preparation over thousands of years. High salinity was used to select the functional microbiota and conducted food production with unique flavor. Although a environment is beneficial suppressing harmful microbes in open environment, efficiency partially inhibited. Therefore, application defined starter cultures reduced-salt sterile an alternative approach improve foods guide transformation traditional industry. However, assembly function self-organized are still unclear. This study provides comprehensive understanding microbial mechanism community succession during broad bean paste so as reconstruct realize efficient environment.
