Gutian Hong Qu glutinous rice wine (GHQW) is a representative alc. beverage in China. During its traditional brewing process, multiple strains are involved. However, the roles of these microorganisms, particularly their contributions to aroma formation, are poorly understood. Therefore, in this study, the dynamics of volatile components and microbial succession during the traditional fermentation process of GHQW were monitored, by using HS-SPME-GC/MS and high throughput 16 S rRNA and ITS sequencing techniques. Following a 32-day semi-open solid-state fermentation, massive changes in volatile profile and microbial communities were observed Based on these, the potential correlations between volatile components and microorganisms during the fermentation were explored by using Pearson correlation anal. It was revealed that 3 bacterial taxa, including Lactococcus lactis, Burkholderia gladioli and Cronobacter helveticus, and 5 fungal taxa, including Wickerhamomyces anomalus, Saccharomyces cerevisiae, Aspergillus vitricola, Aspergillus penicillioides and Monascus purpureus, showed strong connections with various volatile components. Thus these bacteria and fungi might play crucial roles in volatile components biosynthesis, and thus were preliminary considered as core functional microorganisms for GHQW brewing. The detailed information on the dynamic changes of volatile components and microbial communities throughout GHQW brewing can further expand our understanding of the formation mechanisms of GHQW aroma. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0HPLC of Formula: 2198-61-0).
Isopentyl hexanoate (cas: 2198-61-0) 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. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.HPLC of Formula: 2198-61-0
