“…The inactivation of microorganisms using plasma treatment generally results in an exponential decay, depending on time [26]. In the current study, the HuNoV GII.4 survival curve in only PMA-treated oyster was fitted using the first-order kinetics model.…”

“…The plasma equipment employed in this study is shown schematically in Figure 1. The DBD plasma device (µ-DBD Surface Plasma Generator, Model, Micro DBD plasma) was supplied by the Plasma Biomedicine Institute (Plasma Bioscience Research Center, Seoul, Korea) and has been described by Choi et al [26]. The device was turned on for at least 10 min before the start of the experiment, and the surface of the oyster samples inoculated with HuNoV GII.4 was treated with DBD plasma for 0, 10, 20, 30, and 60 min in a sterile petri dish (35 × 15 mm).…”

“…The reduction kinetics of microbial contaminants in oyster samples after DBD plasma treatment were analyzed for D-values (decimal reduction time) using a first-order kinetics model. The D-value calculation for HuNoV genomic titer reduction in the oyster samples followed the method described in Choi et al [26].…”

“…The whole oyster sample's pH and Hunter colors were measured according to DBD plasma treatment time. The pH and Hunter colors were analyzed by the methods described in Choi et al [26] and Albertos et al [29]. For Hunter color measurement, the color of each whole oyster meat sample treated with DBD plasma was measured using a colorimeter (UltraScan PRO, Hunter Lab, Reston, VA, USA).…”

This study investigates the effects of dielectric barrier discharge (DBD) plasma treatment (1.1 kV, 43 kHz, N2 1.5 L/min, 10~60 min) on human norovirus (HuNoV) GII.4 infectivity in fresh oysters. HuNoV viability in oysters was assessed by using propidium monoazide (PMA) as a nucleic acid intercalating dye before performing a real-time reverse transcription–quantitative polymerase chain reaction (RT-qPCR). Additionally, the impact of the DBD plasma treatment on pH and Hunter colors was assessed. When DBD plasma was treated for 60 min, the HuNoV genomic titer reduction without PMA pretreatment was negligible (<1 log copy number/µL), whereas when PMA treatment was used, HuNoV titer was reduced to >1 log copy number/µL in just 30 min. D1 and D2-value of HuNoV infectivity were calculated as 36.5 and 73.0 min of the DBD plasma treatment, respectively, using the first-order kinetics model (R2 = 0.98). The pH and Hunter colors were not significantly different (p > 0.05) between the untreated and DBD-plasma-treated oysters. The results suggest that PMA/RT-qPCR could help distinguish HuNoV infectivity without negatively affecting oyster quality following >30 min treatment with DBD plasma. Moreover, the inactivation kinetics of nonthermal DBD plasma against HuNoV in fresh oysters might provide basic information for oyster processing and distribution.

“…Moreover, ROS and RNS can attack both the cell envelope and components of microorganisms, causing cellular envelope collapse and damage to intracellular components (e.g., DNA). These active species can damage the cell lipid and the protein of the cell membrane, thus allowing for physical and chemical sterilization [24]. It was reported that the concentration of active species (ROS, RNS) can be proportionally increased as there is an increase in power and exposure time and exposure distance in DBD plasma treatment [6].…”

This study investigated the effects of atmospheric dielectric barrier discharge (DBD) plasma (1.1 kV, 43 kHz, 5–30 min, N2: 1.5 L/m) on the reduction of Escherichia coli and Bacillus cereus on dried laver. The reductions of E. coli and B. cereus by 5, 10, 20, and 30 min of DBD plasma were 0.56 and 0.24, 0.61 and 0.66, 0.76 and 1.24, and 1.02 and 1.38 log CFU/g, respectively. The D-value of E. coli and B. cereus was predicted as 29.80 and 20.53 min, respectively, using the Weibull model for E. coli (R2 = 0.95) and first-order kinetics for B. cereus (R2 = 0.94). After DBD plasma 5–30 min treatment, there was no change in pH (6.20–6.21) and this value was higher than the untreated dried laver (6.08). All sensory scores in DBD plasma-treated laver were determined as >6 points. The 30 min of DBD plasma is regarded as a novel intervention for the control of potential hazardous bacteria in dried laver.
