“…e effects of plasma treatment on wheat seed germination and seedling growth, together with changes in the surface chemistry and characteristics of the wheat seeds exposed to plasma, were investigated by Los et al [62]. Treatments of 30-60 s significantly enhanced the germination rate and showed positive effects on seedling growth.…”

This paper presents the review of effects of nonthermal plasma (NTP) treatment on both the wheat grains and flour with potential to be applied in practice. The NTP can be used in wheat grain surface disinfection, grain germination and vitality improving, and wheat flour modification and disinfection. NTP causes effective decontamination from bacteria and fungi together with insect pests and causes minimal damage to wheat grains; it inactivates enzymes and enhances the grain shelf life; it enhances the germination and initial state of growth resulting in the increase of final yield. Moreover, the production of qualitatively better dough is also mentioned.

“…These results indicate the importance of assessing ACP-treated products in multiple toxicity models and, ultimately, in the context of ingestion systems. The higher toxicity in vitro of cereal-based models used in this study as compared to lettuce broth could be attributed to the different medium complexity and composition [ 16 ] with potential for both carbohydrate, lipid and protein fractions of the wheat flours to undergo structural changes as a result of degradation or oxidation [ 17 , 18 ]. ACP-treated WMM and WGE resulted in cytotoxic effects on mammalian cells.…”

“…The final concentrations of nitrite and nitrate resulting from supplementation with WMM did not exceed 5 µM and 0.5 mM, respectively, while up to 1.2 mM nitrite or nitrate were well-tolerated in the same cell model [ 11 ]. In addition to these effects, significant increases in the concentrations of malondialdehyde (MDA) were also observed for ACP-treated wheat grains [ 18 ]. MDA, a product of lipid peroxidation, is known for its cytotoxic properties.…”

Atmospheric cold plasma (ACP) is under investigation for an extensive range of biocontrol applications in food biosystems. However, the development of a novel intervention technology requires a thorough evaluation of the potential for negative effects and the implications for the human and animal food chains’ safety. The evaluations were performed using a contained, high-voltage, dielectric barrier discharge plasma system. The cytotoxicity of two types of food models—a liquid model (wheat model medium (WMM)) vs. a solid model (wheat grain extract (WGE)) was compared in vitro using the mammalian cell line CHO-K1. The residual toxicity of ACP treatment of grains for food purposes was assessed using the invertebrate model Tribolium castaneum, by feeding the beetles with flour produced from ACP-treated wheat grains. The cytotoxic effects and changes in the chemistry of the ACP-treated samples were more pronounced in samples treated in a liquid form as opposed to actual wheat grains. The feeding trial using T. castaneum demonstrated no negative impacts on the survivability or weight profiles of insects. Investigations into the interactions of plasma-generated species with secondary metabolites in the food matrices are necessary to ensure the safety of plasma for food applications.

“…In another study, cold plasma treatment significantly improved the germination (up to ≥84%) with 57% increase in root length, and seedling height (69%) compared to the untreated brown rice (Yodpitak et al., 2019). The probable reasons of CAP effect on cereal grain germination are that plasma triggers the modification in seed coat structure and increase water uptake ratio which influences the germination of grains (Los et al., 2019; Sheteiwy et al., 2019). Nevertheless, the type of exposure and working condition also influences (positively/negatively) the germination of cereal grain.…”

Cold plasma technology (CPT) is considered as one of the emerging alternative techniques for preserving food commodities, extending shelf life, and retaining bioactive compounds in foods. Due to non‐thermal nature, CPT is a useful technology for the sterilization process, especially for heat‐sensitive foods. However, CPT in food is still an emerging process in terms of safety evaluation. Release of secondary products such as ozone, UV, and reactive oxygen species during plasma generation limits its competencies and usage in food industry. Therefore, this review focuses on the application of various types of cold plasma on plant and animal produces. The current state of the CPT application and its effect on food matrices, bioactive compounds, packaging materials, and specific nutrients of food, along with advantages, limitations, and future recommendations of this technique in food sector are discussed. Practical applications Cold plasma technology (CPT), an emerging green nonthermal process, offers numerous potential applications in food and biomedical industries. With rapid advancements in plasma science, the application of CPT for surface decontamination of both food products and food packaging materials is advancing. Though CPT is rapidly gaining acceptance among the food sector, the long‐lasting effect of generated reactive oxygen species is still unclear. This work summarizes the recent developments of CPT on various plant‐ and animal‐based food matrices and aims at highlighting its potential applications, current research, and trends in the area. By examining the safety of gases used in CPT, this review will help both consumers and food processors to understand the safety of the treatment and its wide‐scale commercial application in food.
