This study determined the impact of food residues on the recovery of Listeria monocytogenes and Salmonella Typhimurium from stainless steel surfaces. Results show that food residue types tested in the present study had differentially impacted the recovery of L. monocytogenes and Salmonella during environmental monitoring. Abstract This study evaluated the impact of different food residues on the recovery of Listeria monocytogenes and Salmonella Typhimurium from stainless steel surfaces. Food residues tested include lettuce rinsate, blended lettuce, low-fat milk, and whole milk for Listeria m ..read more

Schematic illustration of PO combined with NFT inhibiting browning and maintaing qualities of fresh-cut nectarines. Abstract Fresh-cut fruits were convenient for consumers but vulnerable to quality deterioration, including browning, softening, and volatile aroma loss. In this study, the whole nectarines were pretreated with 100% O2 (pure oxygen, PO) for 2 h and stored at near-freezing temperature (NFT, −1.5 ± 0.1°C) for 9 days after cutting. We investigated the changes of samples in browning degree, enzyme activity, cell membrane permeability, antioxidant activity, and aroma components. Spec ..read more

Amphora coffeaeformis was extracted and the phytochemical profile of the extract was assessed by GC/MS and HPLC. The antimicrobial (antibacterial and antifungal) activity was evaluated on some pathogenic bacterial species and some mycotoxigenic fungus strains. In addition, the larvicidal activity of the Amphora coffeaeformis extract was evaluated against Culex pipiens L. larvae. Abstract The extensive use of synthetic antibiotics and insecticides in controlling microbes and insect spreads led to a build-up of resistance strains and caused negative impacts on human health through bioaccumulat ..read more

Bacillus velezensis was the dominant spoilage bacteria of quinoa fresh noodles (QFN), which has been evidenced in previous study. Synergistic antimicrobial effects of cinnamaldehyde and eugenol by checkerboard method were suggested to prolong the storage of QFN. The antimicrobial mechanisms were achieved in variable vitro tests. Abstract The synergistic effects of eugenol and cinnamaldehyde (MEC) were firstly used for quinoa fresh noodles (QFN) preservation. The amount of eugenol and cinnamaldehyde in combination was reduced 75% MIC value and 50% MBC value compared to the single application ..read more

This research study the effect of the food product, even present in trace in the bacteria's habitat, on the bacteria potential of biofilm formation. Understanding the conditions that favor or disadvantage the formation of biofilms could help in the development and implementation of new alternative strategies to combat food-borne infections. Abstract The aim of this study is to understand the effect of the food product's, even in trace amounts, in the biofilm formation potential of Escherichia coli and Staphylococcus aureus. Bacterial adhesion was tested using three different food media, in w ..read more

Using polymer blends of polylactide (PLA) and polyadipic acid/butylene terephthalate (PBAT) as matrix, and chitosan (CS), zinc oxide nanoparticles (ZnONPs) or Ag nanoparticles (AgNPs) loaded sodium alginate (SA) as coatings, a series of multilayer films were prepared via a starch-based adhesive. Abstract In this study, polylactic acid (PLA) and polyadipic acid/butylene terephthalate (PBAT) blend polymer were used as matrix to prepare PLA/PBAT substrate film by twin-screw extruder. A series of multilayer films were prepared by starch-based adhesive by loading 1% chitosan (CS), 1% zinc oxide n ..read more

A novel loop-mediated isothermal amplification assay was established on the basis of screening and verification of detection targets for rapid detection of Staphylococcus aureus. After amplification, there are two distinct methodologies for result determination: one involves the analysis of fluorescence curves, while the other involves the observation of color changes. Abstract A loop-mediated isothermal amplification (LAMP) method combined with calcein was established for the detection of Staphylococcus aureus. LAMP primers were designed targeting the ASL18_04625 species-specific gene scree ..read more

The dielectric barrier discharge (DBD) cold plasma with different voltages (60, 70, and 80 kV) was used on rainbow trout. DBD treatment is effective in maintaining the quality of fillets, delayed the moisture loss, myofibril fragmentation index increase, myofibril fragmentation, and texture softening of fillets during storage. Abstract In this study, the effect of dielectric barrier discharge (DBD) cold plasma at different voltages (60, 70, and 80 kV) on the freshness and quality changes of rainbow trout was investigated. The results showed that the voltage of DBD was negatively and positive ..read more

We demonstrated for the first time that Salmonella enterica Typhimurium can form dry surface biofilms (DSB) on surfaces. Mean reduction in viable cells recovered from Salmonella Typhimurium DSB following treatment with water (A and C) or the most efficacious disinfectant formulation (B and D) tested from a panel of candidates, with or without a subsequent wiping step. Contact times used were as per manufacturer's instructions. Abstract In food preparation and manufacturing environments, surfaces contaminated with Salmonella can lead to outbreaks of Salmonellosis. We hypothesise that Salmonel ..read more

Combined antibacterial effect of Origanum essential oils and antibiotics against multiresistant foodborne Salmonella in Morocco. Abstract The present study aims to assess the antibacterial activity of endemic Moroccan Origanum essential oils (Origanum elongatum and Origanum compactum) alone and in association with antibiotics against multidrug resistant foodborne Salmonella. The well diffusion and microdilution procedures were used to evaluate the antibacterial activity. The synergistic interactions between antibiotics and EOs were determined using the checkerboard assay. The results of the ..read more
