In this study, we combined atmospheric cold plasma treatments with an antimicrobial solution containing specific organic acids generally recognized as safe (GRAS) by the FDA and tested its antimicrobial efficacy against <i>Salmonella enterica</i> inoculated on tomato surfaces. Tomato surfaces were inoculated with at 5.6 log CFU/g of <i>Salmonella</i> by spotting 0.1 mL of 7 log CFU/ml <i>Salmonella</i> onto the tomato stem scars, and by dipping whole tomatoes into a solution of 7 log CFU/ml <i>Salmonella</i> for 3 min to achieve 4.1 log CFU/g. Antimicrobial efficacy of the organic acid-based sanitizer + cold plasma treatments for 30, 60, 120, 180, and 360 s, were investigated, and significant bacterial inactivation was achieved above 120 s treatments. At 120 s, surviving populations of aerobic mesophilic bacteria recovered on the tomatoes surfaces averaged &lt; 2 logs/g while yeast and mold survival averaged &lt; 1 CFU/g. Treatment combination with this organic acid-based sanitizer + cold plasma for 120 s resulted in a 4.9 log reduction of <i>Salmonella</i> on the stem scar area and a 3.9 log reduction on the smooth peel surface. Similarly, populations of aerobic mesophilic bacteria recovered on treated tomato surfaces averaged &lt; 0.3 log CFU/g. The results of this study indicate that combining an organic acid-based sanitizer with cold plasma treatments for ≥ 120 s can inactivates significant populations of <i>Salmonella</i> to enhance the microbial safety of tomato surfaces designated for fresh-cut salad.</p>\u0000 </div>","PeriodicalId":15814,"journal":{"name":"Journal of Food Safety","volume":"44 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142525544","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 antibacterial and antibiofilm efficiency was evaluated under different conditions, shedding light on their mode of action against <i>V. parahaemolyticus</i>.

The formation of <i>V. parahaemolyticus</i> biofilm was hindered by the presence of the BBSAs, especially at higher concentrations of BBSAs and during the early intervention stage. After exposure to 1 MIC of BBSA, the inhibition rate of biofilm reached 91.94%. The release of cellular components and alterations in membrane morphology indicated that BBSAs can damage the integrity of <i>V. parahaemolyticus</i> cell membrane. Furthermore, BBSAs may interact with membrane proteins, causing a notable conformational change in membrane proteins.

AV, PV, and linolenic acid (LNA) were referenced to international standards for vegetable oil (0.6 mg KOH/g, 10 mEq of oxygen/kg oil, and 2% for AV, PV, LNA respectively). The initial oil temperature was 130°C ± 1°C, with final temperatures between 145.7°C ± 6.8°C at the lowest and 156.8°C ± 13.0°C at the highest, well below existing studies (≥170°C–250°C). Based on AV and PV, Oo, Po, and Cco were stable up to the fourth, fifth, and eighth frying repeat (FR). The PV of Cnlo (10.2 mEq of oxygen/kg oil) and Sfo (15.5 mEq of oxygen/kg oil) exceeded the maximum limit after one use. The Fresh Cnlo LNA (7.35%) was higher than the limit, while the rest of the oils remained lower and stable until the seventh FR. Po exhibited the highest average antiradical activity (85.42% ± 4.63%), followed by Oo (31.01% ± 10.26%), Sfo (27.96% ± 9.67%), Cnlo (21.85% ± 5.71%), and Cco (14.40% ± 3.46%).

Firstly, support vector machine (SVM) classification models were built using spectral data preprocessed with Savitzky–Golay (SG), discrete wavelet transform (DWT), and standard normal variate (SNV) methods, respectively, and SNV was determined to be the best preprocessing method. Secondly, the gradient boosting decision tree (GBDT) algorithm, principal component analysis (PCA), and the successive projections algorithm (SPA) were respectively used to extract feature wavelengths. Pesticide residue identification models based on full and feature wavelengths were then respectively established using backpropagation neural network (BPNN), SVM, and partial least squares discriminant analysis (PLS-DA). The results show that the BPNN model developed using the feature wavelengths obtained from GBDT was the best for identification of pesticide residues, with an accuracy of 97.8% for both the training and testing sets.
