Films were prepared using the solution casting method; their different properties were evaluated over 1 month at room temperature. Both types of films displayed strong antimicrobial activity against Staphylococcus aureus (S. aureus), Listeria monocytogenes (L. monocytogenes), Escherichia coli (E. coli), and Salmonella typhimurium (S. typhimurium). Pectin-based film incorporated with CEO displayed greater antioxidant activity than film incorporated with TEO. The two EOS increased the films' elongation at break and tensile strength. However, their moisture content and thickness decreased. The antibacterial and antioxidant activities of the CEO- and TEO-based films decreased after 4 weeks of storage, while moisture content increased. However, the films' mechanical parameters remained stable during the entire storage period.","PeriodicalId":15814,"journal":{"name":"Journal of Food Safety","volume":"44 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138604262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This non-random cross-sectional study was conducted between October and December 2022, with 1100 students (721 nursing and 379 medical) completing self-administered questionnaires. 949 (86.3%) of the respondents were female and 151 (13.7%) were male (mean age 20.90 ± 1.74). Nursing students outperformed medical students in food safety KAP scores (19.45 ± 3.19 vs. 19.13 ± 3.36), (10.61 ± 1.52 vs. 10.27 ± 1.80), and (46.96 ± 6.48 vs. 42.87 ± 6.49), with significant differences in food safety attitudes and practices (p < 0.05), as well as knowledge regarding personal hygiene, food preparation, cooking, foodborne pathogens, and cross-contamination (p < 0.05). Multivariate stepwise linear regression analysis revealed predictors of food safety knowledge, including age, residence, academic year, personal food poisoning experience, and familiarity with food safety authority (p < 0.05). Similarly, institutional context, gender, income, residential status, academic year, personal cooking habit, father's education level, and mother's education level had a substantial impact on the attitudes of students. Predictors of safe food handling practices encompassed institutional context, age, gender, family monthly income, residential status, academic year, father's education level, personal food poisoning experience, and familiarity with food safety authority (p < 0.05). These findings highlighted the need for targeted educational interventions to improve food safety KAP among nursing and medical students considering their forthcoming responsibilities as carers.","PeriodicalId":15814,"journal":{"name":"Journal of Food Safety","volume":"44 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138603523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, this study investigated the effects of ultrasound-assisted chlorogenic acid grafted chitosan (GUA) soaking of sea bass (Lateolabrax japonicus) fillets on protein oxidation and gelation properties. The results showed that GUA could reduce the formation of protein carbonyls and maintain Ca2+-ATPase activity. Intrinsic fluorescence intensity (IFI) and SDS-PAGE results demonstrated that GUA stabilized the tertiary structure of protein and inhibited protein degradation. Interestingly, ultrasound attenuated the protein aggregation induced by the use of chitosan-grafted-chlorogenic acid (CS-g-CA), which has good particle size during storage. Meanwhile, GUA treatment endowed the gel with a dense network microstructure, increased water holding capacity (WHC), reduced water mobility, and improved MP gel color as well as textural properties.","PeriodicalId":15814,"journal":{"name":"Journal of Food Safety","volume":"43 6","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138564878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The biofilm formation abilities of nine B. cereus strains isolated from food and two reference strains (ATCC 10876 and ATCC 25621) were measured using a crystal violet assay. Among the tested strains, three strains (GIHE 617-5, GIHE 86-09, and GIHE 728-17) and both reference strains were capable of biofilm formation. A positive correlation was obtained for higher cell surface hydrophobicity and increased biofilm formation. In contrast, HPLC analysis for elevated autoinducer-2 (Al-2) production revealed a negative impact on biofilm formation. PCR data indicated that all tested strains were capable of producing common B. cereus enterotoxins, including Hbl—A, C, and D, CytK, Nhe—B and C, EntFM, and BceT, but were negative for production of the emetic toxin cereulide and the pore-forming toxin Hly II. Meanwhile, RT-PCR data revealed a close correlation between high biofilm formation and the upregulation of several tested virulence genes for selected strains. However, elevated upregulation of virulence genes was not consistent in all of the higher biofilm-forming strains. Cytotoxicity analysis revealed higher virulence characteristics compared to those of low biofilm-forming strains.","PeriodicalId":15814,"journal":{"name":"Journal of Food Safety","volume":"43 6","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135169249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a phagomagnetic separation in combination with qPCR (PhMS-qPCR) based on phage T102 as a recognition element was developed for rapid enrichment and detection of Salmonella in dairy products. Phage T102 was coated onto magnetic beads for capturing Salmonella from samples through magnetic separation, with a capture efficiency of ~90% demonstrated. During the subsequent qPCR process, captured Salmonella was identified by detecting the OmpC gene, and specific sdf and STM4495 genes to further distinguish the serotypes of Salmonella Enteritidis (SE) and Salmonella Typhimurium (ST), respectively. The whole procedure can be performed in 2.5 h with a low detection limit of 10 CFU/mL in PBS. Subsequently, this detection strategy was successfully applied for the detection of Salmonella and serotype identification in spiked milk samples. This cell separation and detection system offers a promising alternative for rapid and accurate detection of Salmonella or Salmonella spp.","PeriodicalId":15814,"journal":{"name":"Journal of Food Safety","volume":"43 6","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135926186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The occurrence of aflatoxins was associated with high proportions of A. flavus and A. parasiticus. Complete removal of AFB1 from walnuts and DON from roasted coffee beans was achieved by treatment with aqueous selenium, while the levels of ZEN and AFG1 were respectively lowered by 65% to 89% depending on the commodity and by about 56% in roasted coffee beans.
