MetabolomicsTitanium dioxide in food induces sex- and microbiota-dependent metabolic disorders, and worsens high-fat diet outcomes
Ultra-processed food consumption has been linked to the rising global burden of metabolic diseases, but the specific contribution of additives commonly used in these products remains unclear. Given the bactericidal properties of the food-grade (fg) additive titanium dioxide (TiO2) and the key role o...

MetabolomicsAntimicrobial Efficacy of Bifidobacterium longum FB1-4 Cell-Free Supernatant Against MRSA: Insights into Mechanisms and Food Matrix Application

The food safety landscape faces a significant challenge from methicillin-resistant Staphylococcus aureus (MRSA), a virulent and antibiotic-resistant foodborne pathogen. This study investigates the antimicrobial properties and mechanisms of cell-free supernatant (CFS) from Bifidobacterium longum F...

MetabolomicsMicrobial liberation of N-methylserotonin from orange fiber in gnotobiotic mice and humans
Plant fibers in byproduct streams produced by non-harsh food processing methods represent biorepositories of diverse, naturally occurring, and physiologically active biomolecules. To demonstrate one approach for their characterization, mass spectrometry of intestinal contents from gnotobiotic mice, ...

MetabolomicsMicrobial Diversity and Non-volatile Metabolites Profile of Low-Temperature Sausage Stored at Room Temperature
Sausage is a highly perishable food with unique spoilage characteristics primarily because of its specific means of production. The quality of sausage during storage is determined by its microbial and metabolite changes. This study developed a preservative-free low-temperature sausage model and coat...

MetabolomicsThe stability and functional redundancy of a microbial cheese ecosystem subjected to a biotic perturbation
The cheese microbial community is dense with relatively low complexity and composed of cultivable prokaryotic and eukaryotic microorganisms. The ripening process can thus be reproduced under controlled conditions. A reduced microbial community composed of yeasts and bacteria was assembled to mimic t...

MetabolomicsMulti-omics insights into high-carotenoid hybrid potato lines: enhanced nutritional quality and metabolic regulation for food applications

Modern potato varieties often exhibit low carotenoid content, limiting their nutritional value and processing performance. This study employed a multi-omics approach (physicochemical analysis, metabolomics, mineral profiling, transcriptomics, and microbiome sequencing) to investigate the molecula...

MetabolomicsApplication of the Protease-Resistant Antimicrobial Peptide R7I, Composed of Natural Amino Acids, as a Functional Food Ingredient for Modulating Intestinal Health

Foodborne pathogenic bacterial infections pose significant challenges to global food safety and public health, while the issue of antimicrobial resistance (AMR) has worsened in recent years, creating an urgent need for safe, natural alternatives to combat foodborne pathogens and associated intest...

MetabolomicsSmall intestinal microbial dysbiosis underlies symptoms associated with functional gastrointestinal disorders
Small intestinal bacterial overgrowth (SIBO) has been implicated in symptoms associated with functional gastrointestinal disorders (FGIDs), though mechanisms remain poorly defined and treatment involves non-specific antibiotics. Here we show that SIBO based on duodenal aspirate culture reflects an o...

MetabolomicsRole of jeotgal, a Korean traditional fermented fish sauce, in microbial dynamics and metabolite profiles during kimchi fermentation
We investigated the effects of jeotgal (fermented fish sauce) on kimchi fermentation, with or without saeu-jeot and myeolchi-jeot. Bacterial community analysis showed that Leuconostoc, Weissella, Lactobacillus, and Tetragenococcus were the dominant genera; however, their succession depended on the p...

MetabolomicsMicrobial community-scale metabolic modelling predicts personalized short-chain fatty acid production profiles in the human gut
Microbially derived short-chain fatty acids (SCFAs) in the human gut are tightly coupled to host metabolism, immune regulation and integrity of the intestinal epithelium. However, the production of SCFAs can vary widely between individuals consuming the same diet, with lower levels often associated ...
