Zizhong Dongjian (ZZDJ) is one of the most famous and popular fermented vegetables in China. The aim of this study was to explore the microbial communities and volatile flavor compounds of ZZDJ during different fermentation periods, as well as to reveal the potential correlation between microbiota and flavor. A total of 84 volatile flavor compounds were detected in 0-year to 3-year ZZDJ samples. Hydrocarbons were the most abundant flavor compounds in 0-year and 1-year samples, while esters became the predominant flavor components in 2-year and 3-year samples. Furthermore, , , and were most predominant bacteria during the fermentation process of ZZDJ. Interestingly, all the fungi identified were yeasts. Among them, and dominated alternatively throughout the fermentation process of ZZDJ. Through analysis of relativity between flavor compounds and microorganism of ZZDJ, we found that sp., , , and might play important roles in flavor information of ZZDJ.

Department of Food Hygiene, Faculty of Veterinary Medicine, Shahid Chamran University of Ahvaz, Ahvaz, Iran.
Purpose: The current study aimed to investigate the trophocidal and cysticidal activities of cinnamaldehyde (Cinn), a natural compound with known antimicrobial properties, against environmental and reference strains of Acanthamoeba castellanii. Additionally, we explored the potential benefits of Cinn formulated as a nanoemulsion (Cinn-NE) in enhancing its efficacy.
Methods: Cinn-NE was prepared using the ultrasonic emulsification method.

infections of grapes significantly reduce yield and quality and increase phenolic compound oxidation, resulting in color loss, off-flavors, and odors in wine. In this study, metabolites were extracted from grape homogenates comprising healthy or infected grapes from different vintages, cultivars, regions, and maturity stages. Samples were randomly analyzed by direct injection into an ion trap mass spectrometer, with data collected from 50 to 2000 / for 1 min.

Ethnopharmacological Relevance: Banxia Xiexin Decoction (BXD) is a traditional herbal formulation with a bitter flavor that has a long-standing history of use in Asia for treating functional dyspepsia (FD). In traditional Chinese medicine, the bitter flavor is believed to play a critical role in the therapeutic activity of BXD. The ethnopharmacological properties of bitter plant extracts are closely associated with their anti-inflammatory effects, which may contribute to their efficacy in FD.

Enzyme-modified butter (EMB) is well-known for its rich flavour, which is primarily defined by the process of enzymatic hydrolysis. This study employed lipidomics and flavouromics to assess the differences between EMBs and to uncover the intrinsic links between volatile organic compounds (VOCs) and lipids. Approximately 273 lipids and 82 VOCs were identified in butter.

A complex microbial community is critical for developing unique flavors in semi-dried large yellow croaker (Pseudosciaena crocea). Volatilomics analysis identified hexanal, heptanal, nonanal, phenylacetaldehyde, 1-octen-3-ol, and butanoic acid were identified as the key flavor compounds in the fish. Clostridium sensu stricto was the dominant genus, with a relative abundance of 79.
