“…Our results (Figure 2a,b) are in accordance with the degradation of aflatoxin B1, DON, and nivalenol by Park et al [17] who used a microwave argon plasma jet as well as by Ouf et al [16] who demonstrated the reduction of fumonisin B2 and ochratoxin A by an atmospheric pressure argon kHz-operated jet. It should be kept in mind that sample temperature measured after the treatment by different approaches differed significantly: 35 °C were estimated after 9 min of treatment by Ouf et al [16] and 105 °C after 5 s of treatment by Park et al [17,30].…”

“…Plasma of different types were used in studies of the inhibition of mycotoxin production and mycotoxin degradation. Ouf et al [16] demonstrated inhibition of the synthesis of fumonisin B2 and ochratoxin A by A. niger after treatment with an atmospheric pressure argon plasma jet. Park et al [17] successfully degraded aflatoxin B1 (AFB1), deoxynivalenol (DON) and nivalenol (NIV) within 5 s using a microwave-induced argon jet at atmospheric pressure.…”

The efficacy of cold atmospheric pressure plasma (CAPP) with ambient air as working gas for the degradation of selected mycotoxins was studied. Deoxynivalenol, zearalenone, enniatins, fumonisin B1, and T2 toxin produced by Fusarium spp., sterigmatocystin produced by Aspergillus spp. and AAL toxin produced by Alternaria alternata were used. The kinetics of the decay of mycotoxins exposed to plasma discharge was monitored. All pure mycotoxins exposed to CAPP were degraded almost completely within 60 s. Degradation rates varied with mycotoxin structure: fumonisin B1 and structurally related AAL toxin were degraded most rapidly while sterigmatocystin exhibited the highest resistance to degradation. As compared to pure compounds, the degradation rates of mycotoxins embedded in extracts of fungal cultures on rice were reduced to a varying extent. Our results show that CAPP efficiently degrades pure mycotoxins, the degradation rates vary with mycotoxin structure, and the presence of matrix slows down yet does not prevent the degradation. CAPP appears promising for the decontamination of food commodities with mycotoxins confined to or enriched on surfaces such as cereal grains.

“…Most reports are restricted to food safety pathogens such as Escherichia coli , Listeria and Salmonella , and are limited to laboratory‐scale trials. There are also some reports that indicate CP could be a prospective control method for fungal pathogens, particularly those that cause postharvest diseases (Basaran et al ., ; Hayashi et al ., ; Ouf et al ., ). Major postharvest fungi include Penicillium spp., Aspergillus spp., Botrytis cinerea , Monilinia spp.…”

Cold plasma: a potential new method to manage postharvest diseases caused by fungal plant pathogens

2018

Development of alternative, chemical‐free approaches for control of postharvest fungi on a commercial scale has become a challenge for plant pathologists in recent years. Although there are several established techniques such as heat that are used as postharvest treatments, they often have disadvantages, including alteration of food quality due to physiological responses to the treatment, or environmental pollution. A promising new postharvest treatment is cold plasma, which is a gas‐derived mix of atoms, excited molecules and charged particles. Cold plasma has no known adverse effects on fresh produce or the environment. It is an established technology in the medical field and has been demonstrated to successfully control bacterial pathogens that cause food safety issues. This review focuses on the potential of cold plasma technology for postharvest disease control, especially those caused by fungi. An overview of plasma generation systems is provided, and in vivo and in vitro research is reviewed to consider benefits, limitations and research gaps in the context of cold plasma as a potential method for controlling postharvest fungal pathogens. Finally, recommendations are provided for the application of this technology in commercial facilities.

“…It is a nonthermal method and enables the elimination of vegetative bacteria, bacterial endospores, molds, and yeasts under nonthermal conditions (Hertwig, Reineke, Ehlbeck, Erdoğdu, et al., ; Kim et al., ). Several studies have been reported on decontaminating effect of cold plasma on agricultural products (Baier et al., ; Basaran, Basaran‐Akgul, & Oksu, ; Jahid, Han, & Ha, ; Kim & Min, ; Lacombe et al., ; Lee, Kim, Chung, & Min, ; Misra et al., ; Niemira & Sites, ; Ouf, Basher, & Mohamed, ; Tappi et al., ), and on spices in particular (Grabowski, Strzelczak, & Dąbrowski, ; Hertwig, Reineke, Ehlbeck, Erdoğdu, et al., ; Hertwig, Reineke, Ehlbeck, Knorr, et al., ; Kim, Oh, Won, Lee, & Min, ; Kim et al., ). However, information about its impact on the quantity and quality of the active ingredients is limited.…”

Cold plasma is known as a novel nonthermal processing method for decontamination of medicinal and aromatic plants ( MAP s); however, there are little research studies about its effects on active ingredients of these plants. The aim of this research was to investigate the influence of low‐pressure cold plasma ( LPCP ) treatments (1, 3, and 5 min) on the essential oil (EO) content and composition of lemon verbena leaves. The EO content was determined using hydro‐distillation, and the composition of the extracted EOs was quantified using gas chromatography and gas chromatography–mass spectrometry techniques. The results showed that by increasing the LPCP treatment duration, the EO content was reduced from 1.2 to 0.9 (% v/w). The highest content of monoterpene hydrocarbons (e.g., limonene) and oxygenated sesquiterpenes (e.g., spathulenol and globulol) was also observed in LPCP ‐treated ones, whereas the oxygenated monoterpenes (e.g., citral) content of control was measurably higher than those treated with LCPC .
