Evaluation of pathogen inactivation on sliced cheese induced by encapsulated atmospheric pressure dielectric barrier discharge plasma

Pathogen inactivation and quality changes in sliced cheddar cheese treated using flexible thin-layer dielectric barrier discharge plasma

“…In the present study, the ozone concentration generated On the other hand, when sealed-type plasma is switched off after period of treatment, the remaining reactive species are trapped inside the sealed container during the post-treatment duration and this will be one of the key treatment parameter that determines consistency in bacterial inactivation (Leipold et al, 2011;Rød et al, 2012). Yong et al (2015) reported that additional 3-4 and 1.5-2 decimal reductions of pathogens inoculated on agar plates and cheese slices, respectively, for 5 min of post-treatment duration using square-type encapsulated DBD plasma system. Therefore, a further inactivation effect can be expected from the present system used in this study.…”

Essential Oils-Based Antibacterial Agent Against Escherichia coli O157:H7 Biofilm on Cucumber

“…Color measurement was performed using a Chromatic meter (Color Quest XE, HunterLab, USA) at six locations on each sample, and expressed as lightness ( L *), redness ( a *), and yellowness ( b* ) (Yong et al . ). Surface texture was evaluated with a TA.XT.…”

Inactivation of murine norovirus-1 and hepatitis A virus on fresh meats by atmospheric pressure plasma jets

“…Song et al (2009) showed that L. monocytogenes on sliced cheese and ham was effectively controlled by APP jets, and that various factors influenced the effectiveness of inactivation. Yong et al (2015) reported that L. monocytogenes on sliced cheese was effectively reduced by encapsulated atmospheric pressure dielectric barrier discharge plasma. Ahlfeld et al (2015) demonstrated that APP treatment impacts the inactivation of NoVII.4 strains on NoV positives stool sample; 1.23 log and 1.69 log genomic equivalents/mL reduction after exposure 10 and 15 min, respectively (initial quantity of 2.36 × 10 4 genomic equivalents/mL).…”
