Article Abstract
A novel Chinese-style sausage with Chinese traditional fermented condiments used as additional ingredients is produced in this study. The aim of this study was to investigate the microbial community's structure, the volatile flavor substances and their potential correlation in the novel Chinese sausage. High-throughput sequencing (HTS) and solid-phase microextraction-gas chromatography-mass spectrometry (GC-MS) were, respectively, used to analyze the microbial diversity and volatile flavor substances of the novel Chinese-style sausage during storage. The results showed that , and were the predominant bacterial genera, and and were the predominant fungal genera. A total of 88 volatile flavor substances were identified through GC-MS, among which 18 differential flavor compounds were screened (VIP > 1), which could be used as potential biomarkers to distinguish the novel sausages stored for different periods. exhibited a significant negative correlation with 2,3-epoxy-4,4-dimethylpentane and acetoin and a significant positive correlation with 2-phenyl-2-butenal. significantly positively correlated with ester. significantly positively correlated with ethyl caprate, ethyl palmate, ethyl tetradecanoate and ethyl oleate while it negatively correlated with hexanal. This study provides a theoretical basis for revealing the flavor formation mechanisms and the screening of functional strains for improving the flavor quality of the novel Chinese-style sausage.

Fermentation and post-ripening plays a significant role in shaping the nutritional value, taste, and aroma of natto. This study aimed to analyse nutritional trends in natto during fermentation and ripening, identify its characteristic volatile organic compounds (VOCs), and elucidate their formation pathways. VOCs were detected using HS-GC-IMS combined with sensory evaluation in the study.

This study investigated the effects of adding Saccharomycopsis fibuligera (SF) and Pichia kudriavzevii (PK) on microbial communities and flavor substances in industrial xiaoqu light-flavor baijiu production. The result showed that the highest acidity was found in the control group (CK: Saccharomyces cerevisiae and Rhizopus) at the end of fermentation. SF and PK promoted the growth of Rhizopus while decreasing the abundance of S.

In the present study, cockles were utilized as the raw material to investigate how different salt concentrations and fermentation periods influence the physicochemical indices, microbial community shifts, and volatile flavor components of cockle paste. Through the analysis of volatile flavor substances via GC-IMS, a total of 77 volatile flavor compounds were identified, among which aldehydes accounted for the largest proportion. High-throughput 16S rDNA sequencing was applied to decode the composition of dominant microbiota in the cockle paste samples.

Fermented foods are valued for their diverse flavor and health benefits, but the formation of ethyl carbamate (EC), a potential carcinogen, during production and storage poses challenges. Current EC reduction methods often compromise flavor and bioactive components. This study exemplifies a novel adsorbent combining activated carbon with metal-organic framework (MOF) chemistry for semi-selective EC removal.

Pu-erh raw tea (PRT), a post-fermented tea, is prized for its complex flavor profile and health-promoting properties. While extended storage enhances its sensory attributes, the decade-scale metabolic dynamics underpinning flavor evolution remain unexplored. This study comprehensively characterized non-volatile metabolomic profiles and flavor changes in PRT across a 10-year storage period (2012-2023).
