“…Niemira (2012) reported that the greatest effect observed was a 1.34 log CFU/mL reduction in Escherichia coli O157:H7 C9490 after a 20 s treatment at a 6 cm distance. With increasing distance from the ionizing potential across the electrodes, these extremely reactive particles tend to recombine with each other instead of the surface to be treated (Niemira and Gutsol, 2010;Ragni et al, 2010). Moisan et al (2001) characterized the inactivation kinetics of plasma and correlated this with the physics and chemistry of the recombined plasma.…”

The optimal conditions for applications of an atmospheric pressure plasma (APP) jet for the inactivation of Salmonella Typhimurium in chicken breast and pork loins were investigated. APP jet treatment for 10 min (versus 5 minutes) showed a higher inactivation of S. Typhimurium in an agar plate, with the best effect at a distance of 20 mm. A treatment on both sides (both-side treatment) for 2.5 + 2.5 min showed a greater inhibition on S. Typhimurium growth compared to single-side treatment for 5 min, with reduction levels of 0.66 log CFU/g in chicken breast and 1.33 log CFU/g in pork loin, respectively. However, there was no significant difference between single-side treatment for 10 min and both-side treatment for 5 + 5 min in chicken breasts and pork loin samples. In conclusion, APP jet treatment conditions, including distance, time, and direction, may affect the inactivation efficiency of S. Typhimurium. In this experiment, distance of 20 mm and both-side treatment were the best conditions. Therefore, the optimal APP jet treatment conditions were evaluated to maximize its practical efficiency.

“…has been reported largely as a potential hazard for egg consumers. Decontamination of egg surface using barrier discharge plasma was studied by Ragni et al (2010). The results showed that maximum reduction of 2.2-2.5 log CFU/eggshell in Salmonella enteritidis levels achieved after 60 -90 min treatment at 35% RH.…”

On contrary, Ragni, L. et al (2010) showed signifi cant reduction in the number of these bacteria, if discharge generated in air was used. published the review surveying the main factors affecting the sensitivity and resistance of Salmonella to cold atmospheric gas plasma treatment as one of the methods for low-temperature innovative processes for food preservation.…”

“…Kříž et al (2014; reported minimal changes in nutrition values of the wheat and triticale seeds treated by Gliding Arc plasma for up to 4 minutes. Ragni et al (2010) applied a resistive barrier discharge for treatment of shell eggs contaminated by Salmonela Enteritidis and Salmonella Typhimurium and no signifi cant negative effects on the eggs quality traits were observed, despite the long treatment times (up to 90 minutes). Wang et al (2016) found that DBD plasma treatment does not cause any signifi cant changes in surface lightness and therefore in the appearance of fresh chicken breast fi llets with contemporary signifi cant enhancement of microbial shelf life.…”
