The material within the Food safety toolbox was based on the Codex Alimentarius (Codex) General Principles of Food Hygiene (GPFH), an internationally recognized primary food safety standard. The GPFH provides a guide to elements that should be considered when establishing good hygienic practices (GHP), which are subsequently managed through hazard analysis and critical control points (HACCP). To support the understanding of how to apply the principles of GHP and HACCP, the online Food Safety Toolbox was developed. This Toolbox was designed to enable users to access the principles quickly as a reminder for better understanding of more complex matters, conceptualizing, and building and maintaining food safety management systems. The learning approaches applied in the design of the Toolbox was mapping, chunking (grouping topics into a logic sequence to enable an incremental approach to learning) and Learn-By-Asking. The self-directed learning approach collectively enables the user to understand, categorize, and contextualize food safety information for practical use. Mapping was performed to identify the different elements within GPFH that formed the basis of the online platform and the categories in which basic information was provided for each. The material progresses into greater depth and includes links to detailed descriptions of the underlying science. This user-centric design was chosen to address different users' needs and reduce the entry barrier for contextually applying the presented GHP and HACCP practices. The GHP and HACCP Toolbox for Food Safety should be regarded as a reference resource rather than a training program to empower the user and ultimately enhance food safety practices.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141381571","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}

The properties of the SAEW that were analyzed included pH, oxidation-reduction potential (ORP), available chlorine concentrations (ACC), and generated hypochlorous acid (HClO) concentration. NaCl alone resulted in the lowest pH (<4) and the highest ORP values (>1000 mV). Increasing HCl concentrations significantly raised pH levels to greater than 5 and lowered ORP values of SAEW, with the highest pH (5.7) observed with 1.5% HCl and 5% NaCl. The highest HClO concentration of 19.65±1.03 mg/L was obtained with 1.5% HCl:5% NaCl. Interestingly, the concentration of NaCl showed no significant effects on the production of HClO. Furthermore, different concentrations of combined NaCl and HCl significantly influenced the inactivation efficiency on total aerobic bacteria count and changes in phenolic compound content. Increasing HCl concentrations from 0.5% to 2.0% led to an increase in the reduction of aerobic bacteria counts from 2.51 to 4.22 log CFU/g with 5% NaCl and from 2.49 to 3.52 log CFU/g with 10% NaCl. Flow rates significantly contributed to the change in HClO formation and altered the properties of the produced SAEW. Results indicated that SAEW treatment significantly reduced total aerobic bacteria counts. The lower flow rates (0.3 L/min) produced the highest log reductions. Additionally, SAEW treatment led to a reduction in phenolic content, even though considerable amount was retained at lower HClO concentrations. These findings offer valuable information on optimizing SAEW treatment protocols for enhancing microbial safety and extending the shelf life of fresh produce, while considering the impact on the content of phenolic compounds.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141115295","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}

Terpene synthases (TPSs) are the key enzymes responsible for the biosynthesis of basic backbone structure of terpenes. Here, we show that genome of cultivated peach (Prunus persica L. Batsch) contains 38 TPS genes, with 24 members in the TPS-a cluster. Transcriptome analysis showed that the expression of PpTPSs in peach fruits was regulated by environmental factors such as UV-B light and low temperature, as well as by phytohormones such as ethylene and MeJA. After analyzing the expression of 38 PpTPSs in peach fruit developmental stages and different tissues, we screened and cloned six new highly expressed TPS genes. Subcellular localization showed that PpTPS13 and PpTPS23 were localized in the plastid, while PpTPS12, PpTPS22, PpTPS25 and PpTPS28 were localized in the cytoplasm. Heterologous expression of PpTPSs in Escherichia coli followed by the enzymatic assays revealed that only four TPSs (PpTPS12, PpTPS22, PpTPS25 and PpTPS28) were active in vitro. Using GPP and FPP as substrates, respectively, these PpTPSs were able to synthesize an array of volatile terpenes, including 15 monoterpenes such as geraniol, camphene, pinene, borneol and phellandrene, and 14 sesquiterpenes such as farnesene, nerolidol and α-bergamotene. Our results provide target genes for engineering to enhance production of volatile terpenes and thereby to improve fruit quality.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141009059","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}

The grafted tomatoes showed significant increases in soluble solids (51.48 %), vitamin C (16.86 %), soluble protein (16.19 %), titratable acid (11.73 %), anthocyanin (11.43 %), and polysaccharide (9.43 %) contents compared to those of the control. Metabolomics analysis identified 234 differentially accumulated metabolites and transcriptome analysis identified 4213 differentially expressed genes between grafted and control tomatoes at three ripening stages (mature green, turning, and fully red). A total of 93 phenolic compounds, including flavonoids and phenolic acids, showed differential accumulation patterns between grafted and control tomatoes at the fully red stage. These changes were attributed to the upregulation of key genes (F3'H, F3’5’H, DFR, ANS) associated with flavonoids and anthocyanin synthesis in the goji rootstock compared to the control. The expression of genes involved in sucrose hydrolysis and starch synthesis, including the invertase (INV), sucrase synthase (SUS), and beta-amylase (BAM) genes, were suppressed by goji grafting, resulting in increased levels of sugars. In addition, the consistency between the transcriptomic and metabolomic data provided a robust validation of the observed quality changes. Altogether, our results demonstrate that grafting onto goji rootstock improves tomato quality by modulating multiple genes involved in phenylpropanoid, sucrose, and starch pathways during fruit development, providing valuable insights for improving the quality and taste of tomato.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140658561","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 work, recombinant Escherichia coli BL21 (DE3) cells expressing optimised lysostaphin (Lst) were constructed, recombinant Lst was produced and purified, and Lst enzymatic assays were performed, followed by antimicrobial testing of Lst. Finally, a mixture of Lst and DNase I was tested for antibiofilm activity. The protein content of purified Lst was 0.6 mg/mL and the enzyme activity was 240 U/mL. The minimum inhibitory concentration (MIC) of Lst against S. aureus was 0.1 μg/mL. At 1 MIC, Lst exerted an effect on the growth, cell wall integrity and cell membrane permeability of S. aureus. Although Lst alone also showed good inhibition and disruption of S. aureus biofilms, inhibition and disruption of S. aureus biofilms was significantly greater when Lst was mixed with DNase I. This is probably because DNase I removes extracellular DNA, affecting biofilm formation and dispersing mature biofilms, and thereby facilitating penetration of Lst.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140668569","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}

Dietary lipids had no significant effect on growth performance and hepatopancreas index (P < 0.05). The carotenoid content showed an increasing and then decreasing trend, with a significant increase to 1312.51 mg/kg (P < 0.05) at 7% lipid content of the diet. In contrast, a diet with a 13% lipid level led to a significant increase in total unsaturated fatty acids (115.3 mg/g, P < 0.05), which maximized the contents of major fatty acids (oleic, linoleic, and linolenic, among others), and present a fluctuating trend. A diet with higher lipid levels (16%) inhibited fatty acid accumulation. Moreover, a 13% dietary lipid level enhanced characteristic aroma compounds (e.g., nonanal, octanal, hexanal, 3-methylbutanal, 2-heptanone, among others) in E. sinensis cooked hepatopancreas. Through an orthogonal partial least squares discriminant analysis (OPLS-DA) model, it becomes evident that lipids and carotenoids together promote aroma formation in hepatopancreas.
