Atmospheric pressure plasma treatment of Listeria innocua and Escherichia coli at polysaccharide surfaces: Inactivation kinetics and flow cytometric characterization

Comparison of volumetric and surface decontamination techniques for innovative processing of mealworm larvae (Tenebrio molitor)

“…Reduction rates between 0.5 and 5.2 log were achieved by plasma treatment of seeds of Brassica napus contaminated with endospores of Bacillus atrophaeus (Schnabel et al, 2011). Furthermore, after a cold indirect plasma treatment the aerobic viable count of pork meat remained between 10 2 and 10 3 CFU/g during a storage period of 20 days at 5°C and showed the applicability of plasma as a gentle surface decontamination method and its potential to prolong the shelf life of food and feed products (Fröhling, Baier, Ehlbeck, Knorr, & Schlüter, 2012;Fröhling, Durek et al, 2012).…”

“…The jet is described in more detail elsewhere (Fröhling, Baier, Ehlbeck, Knorr, & Schlüter, 2012) The maximum temperature of the samples was determined by a thermography camera (SC500, Flir Systems GmbH, Frankfurt a.M., Germany) to be 45°C. The emission spectrum of the plasma is shown in Fig.…”

UV-C light inactivation and modeling kinetics of Alicyclobacillus acidoterrestris spores in white grape and apple juices

“…δ (mJ/cm 2 ) is the UV dose for the first decimal reduction, p (dimensionless) is a shape parameter describing concavity or convexity of the curve. Curves with downward concavity are obtained if p N 1 and curves with upward concavity are obtained if p b 1 (Fröhling et al, 2012).…”

Seed Disinfection Effect of Atmospheric Pressure Plasma and Low Pressure Plasma on Rhizoctonia solani

“…The running pressure of 0.5 torr in their system was much lower than in our system, and they used air gasses or SF 6 as the treatment gas. Because the reactive species vary within the plasma depending on the plasma source, process parameters and process gases Fröhling et al, 2012 , it is difficult to compare inactivation mechanisms of the different plasma sources with those of our system. However, the lower pressure and other gas conditions might improve the inactivation effect in our system.…”
