This study investigated the volatile profiles of tea trichome and tea body across six white tea samples using headspace solid-phase microextraction combined with gas chromatography-mass spectrometry (HS-SPME-GC-MS) and multivariate statistical analysis. Comparative analysis revealed significant differences in the volatile profile between tea trichome and tea body in all tested samples, with major differences lying in the content of volatile components. Sixteen potential key aroma components with relative odor activity value (ROAV) ≥ 1 and 39 aroma modifiers (0.1&lt;ROAV&lt;1) were identified in both tea trichome and tea body, predominantly associated with green, fruity, sweet, floral, woody and herbal aroma. In brief, <em>trans-β</em>-ionone, <em>β</em>-damascone, linalool, non-8-enal and (<em>E,Z</em>)-2,6-nonadienal were identified as key aroma components in both tea trichome and tea body, determining the basic aroma characteristic of white tea. Aroma modifiers were also affirmed, including <em>β</em>-myrcene, 2-ethyl-3,5-dimethyl-pyrazine, (<em>E</em>)-2-hexenal, dehydro<em>-β</em>-ionone, (<em>Z</em>)-6-nonenal, (<em>E,E</em>)-2,4-decadienal and benzeneacetaldehyde, which were shared by all samples in tea trichome and tea body. Notably, most of these key and modified aroma components showed higher relative contents and ROAVs in tea trichome than those in tea body. These data reveals that tea trichome positively enhance white tea's aroma quality, notably intensifying fruity, floral, sweet, green, and woody notes.

The complex toxins that it produces can cause diarrhea, necrotizing enteritis, and even death. This study aimed to evaluate the presence of antibiotic resistance genes and determinants of toxin production in various strains of <em>C. perfringens</em>, derived from different geographical locations and animal sources, through whole-genome sequencing (WGS) and bioinformatics analysis. Antimicrobial resistance testing revealed a notable prevalence of resistance among isolates, with 39.5 % being resistant to clindamycin and 32.6 % resistant to tetracycline. Additionally, 29.1 % of the isolates were found to be resistant to at least two classes of commonly used antibiotics. T<em>etA</em>(<em>P</em>) and <em>tetB</em>(<em>P</em>), associated with tetracycline resistance, were the most frequently identified resistance genes, present in 93.0 % and 79.0 % of the isolates, respectively. Virulence genes encoding extracellular collagenases (<em>colA</em> and <em>colSI</em>), alpha-toxin (<em>plc</em>), and sialidase (<em>nanH</em>) were detected in 85 isolates, representing 99 % of all sequenced strains. Notably, the gene encoding <em>C. perfringens</em> enterotoxin (<em>cpe</em>) was identified in only one isolate, which originated from chicken. Multi-locus sequence typing revealed that the 86 representative isolates belonged to 49 sequence types (STs), including 33 unique, previously uncharacterized STs. Furthermore, 30.23 % of these STs were grouped into six clonal complexes (CCs). CgSNP analysis of globally circulating isolates demonstrated that the prevalence of the virulence gene <em>cpe</em> was higher in these isolates than in clinical strains. The identification of multi-drug resistance and toxin-encoding genes among the isolates underscores the concerning spread of antimicrobial resistance among <em>C. perfringens</em> affecting both animals and humans. The diversity of CRISPR/Cas system provided addition insight into complex genetic correlations and evolutionary dynamics of pathogenic <em>C. perfringens</em>. Notably, the phage SD72 exhibited a broad inhibitory effect against <em>C. perfringens</em> isolates, irrespective of STs types and antimicrobial resistance (74/86, 80.1 %). These findings highlight the urgent need for enhanced epidemic surveillance of <em>C. perfringens</em> in livestock settings to mitigate the risks of human transmission via environmental or food sources.

Recently, functional microbial cultures have been developed by selecting specific microbial strains that enhance the cocoa bean fermentation process and improve the quality of the fermented and dried beans. These selection processes require extensive and time-consuming screening of numerous microbial strains. To address this, the present study explored a rapid, untargeted, metabolite-based approach to distinguish cocoa beans fermented with specific microbial cultures. This was achieved using rapid evaporative ionization mass spectrometry (REIMS) combined with chemometric analysis. Metabolite fingerprints of cocoa beans fermented with 21 antifungal (AF) and/or pectinolytic (P) microbial cultures were analyzed using REIMS. The fermented beans were differentiated based on their metabolite profiles using LiveID software, which is integrated with the REIMS system. Subsequently, six classification models were compared in detail to evaluate their performance, and tentatively extended to classify metabolite fingerprints from independently fermented beans. Initially, LiveID combined with PCA-LDA successfully distinguished metabolite fingerprints based on single-strain microbial cultures and the expected AF or AF&amp;P functionalities of co-cultures, achieving an accuracy of 80 %. Further analysis of the six classification models demonstrated the strong performance of gradient boosting machines, random forests, and neural networks in differentiating metabolite fingerprints based on the functionality of microbial co-cultures, with accuracy estimates of 85 %, 84 %, and 81 %, respectively. Finally, optimized random forest models were tested on an independent dataset, achieving 70–85 % accuracy for the two-class models. The performance of these models on independent data highlights their potential for broader applications, such as differentiating cocoa beans at the lab scale or in on-farm settings to support the development of functional microbial cultures for the production of cocoa beans with consistently high quality.</div></div>","PeriodicalId":10939,"journal":{"name":"Current Research in Food Science","volume":"11 ","pages":"Article 101161"},"PeriodicalIF":7.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144810595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
