Abstract :

Background: Tea, celebrated for its delightful flavors and health benefits, is a globally cherished beverage. Umami taste is an essential contributor to its flavor profile and its perception mechanism is crucial for enhancing the taste quality of tea. The exploration of individual physiological and emotional responses to gustatory signals through physiological measurement techniques makes it possible to decode the mechanisms underlying umami perception. Scope and approach: This article focuses on the umami taste of tea, providing a comprehensive review of the umami substances and the influencing factors. It discusses the umami perception mechanism from the perspectives of both umami-contributing and umami-enhancing aspects. Additionally, the paper explores the application prospects of physiological measurement technologies in decoding umami perception. This review aims to provide new analytical strategies for decoding umami and other taste perceptions. Key findings and conclusions: Umami is one of the important sensory attributes contributing to the taste of tea products. The umami taste in tea is predominantly mediated by amino acids such as L-theanine, L-glutamic acid, and L-aspartic acid, with additional contributions from compounds like succinic acid and methylated catechins. The interaction of these umami compounds with the T1R1/T1R3 receptor complex involves a suite of molecular forces, including hydrogen bonding, hydrophobic interactions, van der Waals forces, and electrostatic interactions, which are essential for the stability and functionality of ligand-receptor binding. Neuroimaging and electrophysiological studies have further elucidated the neural basis of umami perception, providing a comprehensive understanding of the sensory input to cognitive processing associated with this taste modality. © 2025 Elsevier Ltd

Abstract :

High molecular weight polysaccharides (GLPH, >= 300 kDa) are the major compounds of Ganoderma lucidum with improving liver function. However, the effect of GLPH on improving acute liver injury (ALI) wasn't revealed. Herein, the ameliorating effects and mechanisms of GLPH were revealed in lipopolysaccharide (LPS)-ALI mice. The results indicated that GLPH intervention (100 mg/kg day) reduced the serum ALT (22.67 f 6.48 U/L), AST (21.19 f 7.08 U/L), ALP (56.98 f 12.71 U/L), GGT (1.48 f 0.22 U/L) levels in ALI mice (p < 0.01). GLPH activated the hepatic antioxidant enzymes activity [SOD (3.75 f 1.17 U/mg prot.) and CAT (3.01 f 0.85 U/mg prot.)] and suppressed the hepatic inflammatory cytokines production [TNF-alpha (40.14 f 8.15 pg/mg prot.), IL-1 beta (35.47 f 10.90 pg/mg prot.), and IL-6 (8.44 f 1.71 pg/mg prot.)] by regulating the Nrf2/OH-1 and Tlr4/NF-kappa B pathway (p < 0.05). Furthermore, GLPH regulated the abundance of Bifidobacterium, Akkermansia, Anaerovorax, and Tyzzerella, which associated with cecal SCFAs, hepatic inflammatory cytokines and antioxidant enzymes. GLPH significantly changed 85 liver metabolites (p < 0.01), which is beneficial for prevent the development of ALI. These results suggested GLPH displayed promising prebiotic properties in relieving ALI, regulating gut microbiota and liver metabolism.

Abstract&Keyword Cite Version(1)

Abstract :

As a probiotic strain isolated from Hongqu rice wine (a traditional Chinese fermented food), Limosilactobacillus fermentum FZU501 (designated as Lf) demonstrates exceptional gastric acid and bile salt tolerance, showing potential application as a functional food. The aim of this study was to investigate the protective effect of dietary Lf intervention on alcohol-induced liver injury (ALI) in mice. The results demonstrated that oral administration of Lf effectively ameliorated alcohol-induced lipid metabolism disorders by reducing the serum levels of TC, TG and LDL-C and increasing the serum levels of HDL-C. In addition, oral administration of Lf effectively prevented alcohol-induced liver damage by increasing the hepatic activities of antioxidant enzymes (CAT, SOD, GSH-Px) and alcohol-metabolizing enzymes (ADH and ALDH). Interestingly, 16S amplicon sequencing showed that oral administration of Lf increased the number of Prevotella, Lachnospiraceae_NK4A136_group and Lactobacillus, but decreased the proportion of Faecalibaculum, Adlercreutzia and Alistipes in the intestines of mice that consumed excessive alcohol, which was highly associated with improved liver function. As revealed by liver untargeted metabolomics studies, oral Lf clearly changed liver metabolic profiles, with the signature biomarkers mainly involving purine metabolism, taurine metabolism, tryptophan, alanine, aspartic acid and glutamate metabolism, etc. Additionally, Lf intervention regulated liver gene transcription in over-drinking mice for cholesterol metabolism, bile acid metabolism, fatty acid beta-oxidation, alcohol metabolism and oxidative stress. Taken together, the above research results provide solid scientific support for the biological activity of Lf in ameliorating alcohol-induced liver metabolism disorder and intestinal microbiota imbalance.

Abstract :

Wuyi Rock Tea (WRT) undergoes complex chemical transformations during roasting that significantly influence its aroma. This study explores the mechanisms involved in the formation of key aroma compounds, specifically alkylpyrazines and furans. Using HS-SPME-GC-O-MS and aroma dilution analysis, we identified 15 odor-active compounds, including three alkylpyrazines (2,6-diethyl-pyrazine, 2-ethyl-3,5-dimethyl-pyrazine, and 2-methyl3,5-diethyl-pyrazine) and two furans (furfural and 5-methyl-2-furancarboxaldehyde), with odor-active values exceeding 1. An "in-leaf" labeling approach utilizing isotopically labeled alanine ([15N]-Ala) and glucose ([U-13C6]-Glc) was employed to explore the contributions of tea leaf matrix and soluble compounds. Results indicated that the incorporation of two nitrogen atoms from alanine was the predominant pathway for alkylpyrazine formation, while five or six carbon atoms from glucose were primarily responsible for furan formation. Additionally, the insoluble tea leaf matrix contributed 13 % to 32 % of alkylpyrazines and 12 % to 25 % of furans. These findings enhance our understanding of the Maillard reaction's role in WRT's flavor development.

Comparison of lignin degradation and flavor compound formation in roasted tobacco by two Bacillus subtilis strains SCIE

Abstract&Keyword Cite Version(1)

Abstract :

Two strains of Bacillus subtilis designated YY-10 and BY-2, were isolated from the surface of tobacco and found to be capable of significant lignin degradation. The predominant lignin-degrading enzymes produced by these strains were lignin peroxidase (LiP) and manganese peroxidase (MnP), respectively. A notable distinction was observed in the organoleptic evaluation and volatile flavor compounds, as determined by sensory evaluation and GC-MS analysis. The content of volatile flavor compounds, such as geranylacetone, meglumine trienone B, and meglumine trienone C, was found to be significantly increased in roasted tobacco treated with YY-10. This treatment has been shown to reduce the astringent flavor of the roasted tobacco and improve the aroma, which in turn could improve the quality of the roasted tobacco. Conversely, the quality and aroma levels of the roasted tobacco treated with the crude enzyme solution of the BY-2 strain were reduced. Transcriptome analysis revealed that the expression of genes related to amino acid metabolism, genetic material biosynthesis, and protein synthesis was up-regulated in the YY-10 strain compared with the BY-2 strain, which promoted the biosynthesis of LiP. This study provides a preliminary elucidation of the potential mechanism by which YY-10 enhances the quality of tobacco leaves through lignin-degrading enzyme production, thus establishing a research foundation for the subsequent treatment of waste tobacco raw materials and industrial applications.

Abstract :

Chinese rice wine (CRW) is an alcoholic beverage made mainly from rice or grain through saccharification and fermentation with Jiuqu (starter). Jiuqu makes an important contribution to the formation of the flavor characteristics of rice wine. Hongqu and Maiqu are two kinds of Jiuqu commonly used in CRW brewing. This study compared the microbial community, biogenic amines (BAs), and volatile flavor components (VFCs) of two types of rice wine brewed with Hongqu and Maiqu as fermentation agents. The results showed that the amino acid content of rice wine fermented with Maiqu (MQW) was significantly lower than that of rice wine fermented with Hongqu (HQW). On the contrary, the majority of BAs in MQW were significantly higher than those in HQW, except for putrescine. Multivariate statistical analysis indicated that most of the VFCs detected were enriched in HQW, while ethyl 3-phenylpropanoate and citronellol were enriched in MQW. The results of metagenomic analysis showed that Weissiella, Enterobacter, Leuconostoc, Kosakonia, Saccharomyces, Aspergilus and Monascus were identified as the predominant microbial genera in HQW brewing process, while Saccharopolyspora, Lactococcus, Enterobacter, Leuconostoc, Kosakonia, Pediococcus, Pantoea, Saccharomyces, Aspergillus, Lichtheimia and Nakaseomyces were the predominant microbial genera in MQW brewing. In addition, some VFCs and BAs were strongly correlated with dominant microbial genera in HQW and MQW brewing. Bioinformatics analysis showed that the abundance of genes involved in BAs synthesis in MQW brewing was much higher than that in HQW brewing, while the abundances of genes related to metabolic pathway of characteristic VFCs in HQW brewing were obviously higher than those in MQW, which explained the differences in flavor quality between HQW and MQW from the perspective of microbial genes. Collectively, these findings provide scientific evidence for elucidating the contribution of different microbial genera to the formation of flavor quality of CRW, and is helpful for screening beneficial microbes to enhance flavor quality and drinking comfort of CRW.

Abstract :

Fatty acid ethyl esters (FAEE) are key target for wine industry to diversify its production towards fruity flavor. The microbial community and functional enzymes governing FAEE formation during Chinese rice wine (Huangjiu) brewing were investigated in current study. Physicochemical characteristics and FAEE displayed distinct phased changes, which fluctuated sharply in initial fermentation and then leveling off gently. Except for reducing sugar, other factors and FAEE showed strong positive correlations with the dominant microorganisms. Based on metagenomic analysis, Saccharomyces cerevisiae and lactic acid bacteria (LAB) were dominant in production of oxidoreductase, transferase, and isomerase, which significantly contributing to FAEE synthesis. Besides, phosphoglycerate mutase, pyruvate decarboxylase, fatty-acyl-CoA synthase, and trans-2-enoyl-CoA were crucial enzymes for the synthesis of FAEE precursors, with S. cerevisiae making substantial contributions. Microbe-mediated metabolic pathways elucidated that FAEE was mainly synthesized via ethanol and fatty acylCoA (C <= 16) under lipase and alcohol acyltransferase through S. cerevisiae during Huangjiu brewing. The most abundant LAB mainly influenced FAEE via pyruvate metabolism and esterase synthesis. Co-occurrence analysis highlighted the importance of amino acids for FAEE formation, especially lysine. The findings provide insights into optimizing FAEE production for enhanced flavor quality of alcoholic beverages.

Abstract :

Aims To address the increasingly serious challenge of the transmission of foodbrone pathogens in the food chain.Methods and results In this study, we employed rational design strategies, including truncation, amino acid substitution, and heterozygosity, to generate seven engineered peptides with alpha-helical structure, cationic property, and amphipathic characteristics based on the original Abhisin template. Among them, as the hybird antimicrobial peptide (AMP), AM exhibits exceptional stability, minimal toxicity, as well as broad-spectrum and potent antimicrobial activity against foodborne pathogens. Besides, it was observed that the electrostatic incorporation demonstrates by AM results in its primary targeting and disruption of the cell wall and membrane of Escherichia coli O157: H7 (EHEC) and methicillin-resistant Staphylococcus aureus (MRSA), resulting in membrane perforation and enhanced permeability. Additionally, AM effectively counteracts the deleterious effects of lipopolysaccharide, eradicating biofilms and ultimately inducing the demise of both food spoilage and pathogenic microorganisms.Conclusions The findings highlight the significant potential of AM as a highly promising candidate for a novel food preservative and its great importance in the design and optimization of AMP-related agents.

Abstract :

To study the relationship between the diversity of the surface microbial community and tobacco flavor, and to improve tobacco quality using microorganisms. The microbial community composition and diversity of 14 samples of flue-cured tobacco from tobacco-producing areas in Yunnan with varying grades were analyzed by high-throughput sequencing. PICRUSt was used for predicting microbial functions. A strain of Bacillus amyloliquefaciens W6-2 with the ability to degrade pectin was screened from the surface of flued-cured tobacco leaves from Yunnan reroasted tobacco leave. The enzyme preparation was prepared through fermentation and then applied for treating flue-cured tobacco. The improvement effect was evaluated by measuring the content of macromolecule and the changes in volatile components, combined with sensory evaluations. The bacterial communities on the surface of flue-cured tobacco exhibited functional diversity, consisting primarily of Variovorax, Pseudomonas, Sphingomonas, Burkholderia, and Bacillus. These bacterial strains played a role in the aging process of flue-cured tobacco leaves by participating in amino acid metabolism and carbohydrate metabolism. These metabolic activity converted complex macromolecules into smaller molecular compounds, ultimately influence the smoking quality and burning characteristics of flue-cured tobacco. The pectinase preparation produced through fermentation using W6-2 has been found to enhance the aroma and sweetness of flue-cured tobacco, leading to improved aroma, reduced impurities, and enhanced smoothness. Additionally, the levels of pectin, cellulose, and hemicellulose decreased, while the levels of water-soluble sugar and reducing sugar increased, and the contents of esters, ketones, and aldehydes increased, and the contents of benzoic acid decreased. The study revealed the correlation between surface microorganisms and volatile components of Yunnan tobacco leaves, and the enzyme produced by the pectin-degrading bacteria W6-2 effectively improved the quality of flue-cured tobacco.
