Lettuce, the most highly consumed ready-to-eat vegetable, poses a significant risk of B. cereus exposure. Hence, B. cereus monitoring and evaluation during cultivation are essential for preventing foodborne illnesses caused by this food–pathogen combination. However, the impact of different cultivation practices on B. cereus contamination in lettuce currently remains unclear. Furthermore, validity indicator of the experimental models cannot be effectively validated under field conditions. Herein, we assessed the risk of B. cereus exposure using lettuce grown under two different cultivation farming systems in China(open-field versus greenhouse) using a quantitative microbial risk assessment model. Tukey’s mean comparison method and kernel density estimation frequency distribution statistics were used for model validation using environmental samples and lettuce. The mean concentration of B. cereus in open-field-grown lettuce was significantly higher than in greenhouse-grown lettuce (p &lt; 0.05). No significant differences were observed between measured, formula-calculated, and risk assessment values in environmental samples or lettuce (p &gt; 0.05), verifying the accuracy of the risk model. Soil solarization, complete manure treatment, usage of mulch films, and irrigation water quality should be considered in agricultural practices to control B. cereus concentrations in lettuce. Overall, we found that B. cereus was more abundant in open-field-grown lettuce, and we provide a risk evaluation framework that can guide farmers and policy-makers to control B. cereus contamination in farm-to-fork lettuce chains in China.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134991628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods Fresh blueberry fruit were treated with 3.0 g L−1 anthocyanins and stored at room temperature to investigate the effects of the treatment on fruit firmness and nutritional quality. The fruit firmness, ABA content, anthocyanin content and the relative expression levels of key genes were evaluated. Results The results demonstrated that anthocyanins treatment decreased the ABA level by inhibiting the expression of the VcNCED1 gene implicated in ABA synthesis. At the same time, the treatment increased the content of endogenous anthocyanin by promoting the expression of anthocyanin biosynthesis genes such as VcC4H, VcF3H, VcF3’5’H, VcANS, and VcAT. Conclusions Postharvest anthocyanins treatment promoted the synthesis of endogenous anthocyanin and inhibits the accumulation of endogenous ABA, delayed the senescence of blueberries by inhibiting fruit softening and the accumulation of active oxygen.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":"20 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135086400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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, hydrophilic silica aerogel (SiO2NA) was incorporated into corn starch (CS)/chitosan (CH)/rose anthocyanins (RACNs)-encapsulated potato amylopectin nanoparticles (APNPs) composite film to increase the sensitivity for shrimp freshness detection. Microstructure of films revealed that the gas absorption capacity was improved by amorphous SiO2NA via hydrogen interactions. The pore size (1.74-5.60 times), pore volume (3.92-5.60 times), and specific surface area (2.21-2.34 times) of films increased with the addition of SiO2NA. The sensing to NH3 and pH, and reversibility of films were also reinforced. Meanwhile, the pH-responsible films containing SiO2NA changed visibly in color from purple-red to orange-gray and finally to grey, enabling an effective monitoring of shrimp freshness during storage at 4℃. Thus, anthocyanin-based indicator films with improved sensitivity by adding SiO2NA were successfully designed for monitoring shrimp freshness.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135086558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, 37 CitHAT genes were identified in Citrus clementina. Their physicochemical properties, chromosomal location, gene structure, conserved domain and motif, and cis-acting elements were characterized. CitHATs were classified into four subfamilies based on protein sequence homology, which was strongly supported by gene structure, conserved domain, and motif analysis. The cis-acting elements in gene promoter regions were predicted to be associated with the regulation of plant growth, stress resistance, and response to hormones. Phenotypic and transcriptomic analyses of citrus callus with the mock treatment and HAT inhibitor treatment revealed that increased citric acid content in inhibitor treatment may be attributed to differential expression of CitPEPCK2 and CitGS2, which may be due to the hypo-acetylation of histone H3. The expression patterns of CitHATs in citrus fruit development stages showed that CitHAG11 and CitHAG28 exhibited a negative correlation with citric acid content. Our study associates the potential function of histone acetyltransferases in citrate metabolism and extends the molecular mechanism of citrate metabolism in fruits.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":"24 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135087116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this substance has been linked to gastrointestinal disorders. The aim of this study was to investigate the impact of dietary exposure of titanium dioxide E171 on Listeria monocytogenes infection in mice. Mice were mainly divided to control, LM group (L. monocytogenes infection) and E171+LM group (E171 supplementation before L. monocytogenes infection). Pre-exposure to E171 resulted in increased bacterial counts in the liver, spleen, ileum, colon, mesenteric lymph nodes and feces of mice after L. monocytogenes infection. Moreover, E171 exposure increased the levels pro-inflammatory cytokines while attenuating the levels of anti-inflammatory cytokines in mice infected with L. monocytogenes. Meanwhile, mice in E171+LM group exhibited considerably more severe colonic inflammation and worse intestinal barrier function than mice in LM group. The 16S rRNA gene sequencing revealed a shift in the composition of the gut microbiota of mice in E171+LM group, characterized by a decrease in the relative abundance of Firmicutes and a decrease in the Firmicutes-to-Bacteroidetes ratio. The levels of acetate, butyrate, and isobutyrate were markedly decreased within the cecum of mice in E171+LM group in comparison to mice in LM group. In conclusion, these results suggest that E171 exposure could exacerbate L. monocytogenes infection in mice, which may provide useful information for future risk assessment of this commonly used food additive.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136316984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are also concerns over the carcinogenic potential of dietary nitrate and nitrite in the processed meat products. The past few decades have seen extensive search for novel technologies alternative to synthetic chemical preservatives to reduce the level of contamination of foods by pathogenic and spoilage microbes. This review provides general overview of natural preservatives with potential applications in the meat industry, including phages and their endolysins, bacteriocins, microbial lipopeptides, antimicrobial peptides of plant or insect origin, and essential oils or extracts of plant origins. Instead of providing summary data from the published literature, we attempted to elaborate the challenges facing the development of novel natural preservatives as the antimicrobial hurdles, taking into consideration of the fact of sharp contrast between extensive studies in this particular field and very limited industrial use. More specifically, we emphasized the great importance of having streamlined approaches and methodological guidelines in research and development of natural preservatives so that the journey to their industrial use for safer meats and meat products could be shortened or made easier.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135778312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the appropriate concentration of TDZ for mango expansion without a decline in quality is not clear. In the present study, four different concentrations (5 mg/L, 10 mg/L, 15 mg/L and 20 mg/L) of TDZ were applied via spraying on mango plants, and several physiological and biochemical indicators were measured. The results showed that TDZ treatment significantly increased mango fruit size and single-fruit weight. In mango fruit, TDZ treatment decreased the disease index, delayed the increase in the malondialdehyde (MDA) and H2O2 content, and maintained firmness and antioxidant capacities at a relatively high level during postharvest storage. At the same time, TDZ treatment delayed the decrease in the GA3, IAA and JA contents in mango and reduced the accumulation of ABA and ethylene. These trends are consistent with TDZ treatment leading to extension of the shelf life of mango. Furthermore, ethylene biosynthesis, signal transduction and cell wall dismantling-related genes were investigated. The results indicated that the expression of the MiACS, MiETR2, MiERF113, MiERF010, MiERF054, MiEXP, MiPG14, MiPG21, MiCEL and MiPEL genes in mango was inhibited under TDZ treatment compared with the control. In summary, TDZ treatment can significantly increase the size and weight of mango fruit and can extend its shelf life. The most suitable concentration is 10~15 mg/L TDZ, which will not affect the quality of mango fruit.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135803776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
