“…27 Previous studies demonstrated that high concentrations of ozone generated during 5 min of in-package high-voltage indirect DBD ACP treatment (4420 ppm), and other generated chemically reactive species, completely disintegrated Salmonella cells present on the surface of lettuce. 30 Toyokawa et al 31 demonstrated that plasma treatment generated using a DBD plasma roller conveyer and atmospheric air induced slight morphological changes to Xanthomonas campestris oxidation of genomic DNA, leading to cell death.…”

Increasing process complexity and consumer demands for less processed goods has led to strong demand for new effective decontamination methods. Therefore, atmospheric tial for diverse decontamination applications. The aim of this work was to investigate the anof food products after packaging. The approach was tested under both static and continuous modes of treatment against pathogenic microorganisms Escherichia coli and Listeria innocua impact of treatment on produce quality during extended shelf life was also evaluated. Greater than 5 log reductions of E. coli population density surface attached on tomatoes was achieved in 150 s of treatment generated during either static or continuous operational mode. L. innocua be achieved in tandem with quality retention using a pilot scale system in which the mode of operation was optimized for cherry tomato as a representative fresh product.

Cold plasma science and technology is increasingly investigated for translation to a plethora of issues in the agriculture and food sectors. The diversity of the mechanisms of action of cold plasma, and the flexibility as a standalone technology or one that can integrate with other technologies, provide a rich resource for driving innovative solutions. The emerging understanding of the longer-term role of cold plasma reactive species and follow-on effects across a range of systems will suggest how cold plasma may be optimally applied to biological systems in the agricultural and food sectors. Here we present the current status, emerging issues, regulatory context, and opportunities of cold plasma with respect to the broad stages of primary and secondary food production.

“…Compared to that, the treatment of bacteria causing plant diseases has been relatively less explored in the application of plasma ( Table 1). Several studies demonstrate that plasma treatment of phytopathogenic bacterial suspension can reduce the number of viable bacteria in a time-dependent manner (Moreau et al, 2007;Mráz et al, 2014;Toyokawa et al, 2017;Motyka et al, 2018). Gliding arc discharge can effectively inactivate the potato pathogen Erwinia carotovora by altering the bacterial membrane (Moreau et al, 2007).…”

“…The viability of X. campestris pv. campestris placed on a roller plasma conveyer was decreased, showing significant degradation of lipopolysaccharides and oxidation of genomic DNA (Toyokawa et al, 2017). The pathogenicity and colony forming unit of Ralstonia solanacearum were significantly reduced after the discharge plasma treatment of a hydroponic solution (Okumura et al, 2016).…”

Disease stresses caused by pathogenic microorganisms are increasing, probably because of global warming. Conventional technologies for plant disease control have often revealed their limitations in efficiency, environmental safety, and economic costs. There is high demand for improvements in efficiency and safety. Non-thermal atmospheric-pressure plasma has demonstrated its potential as an alternative tool for efficient and environmentally safe control of plant pathogenic microorganisms in many studies, which are overviewed in this review. Efficient inactivation of phytopathogenic bacterial and fungal cells by various plasma sources under laboratory conditions has been frequently reported. In addition, plasma-treated water shows antimicrobial activity. Plasma and plasma-treated water exhibit a broad spectrum of efficiency in the decontamination and disinfection of plants, fruits, and seeds, indicating that the outcomes of plasma treatment can be significantly influenced by the microenvironments between plasma and plant tissues, such as the surface structures and properties, antioxidant systems, and surface chemistry of plants. More intense studies are required on the efficiency of decontamination and disinfection and underlying mechanisms. Recently, the induction of plant tolerance or resistance to pathogens by plasma (so-called "plasma vaccination") is emerging as a new area of study, with active research ongoing in this field.
