“…Elevated in situ H 2 O 2 and NO x concentrations in tomato seedlings in response to plasma-activated water (PAW) was detected by Adhikari et al [61]. Similar observations the accumulation of RONS in response to plasma treatment in plants have also been reported in other studies [43,54]. The impact of RONS on plant development is well known [76,77], so plasma-generated RONS may similarly influence plant growth and development.…”

Cold atmospheric or low pressure plasma has activation effects on seed germination, plant growth and development, and plant sustainability, and prior experimental studies showing these effects are summarized in this review. The accumulated data indicate that the reactive species generated by cold plasma at atmospheric or low pressure may be involved in changing and activating the physical and chemical properties, physiology, and biochemical and molecular processes in plants, which enhances germination, growth, and sustainability. Although laboratory and field experiments are still required, plasma may represent a tool for efficient adaptation to changes in the climate and agricultural environments.

“…Mujahid et al [44] mentioned that it may be instead the hydroxyl radicals which are responsible for the cell wall loosening. Bafoil et al [61] calculated an increased expression of 23 genes for class III peroxidases after plasma treatment, which are proteins localized in the seed coat which regulate concentrations of hydrogen peroxide and precede the rupture for germination.…”

Mechanisms of Plasma-Seed Treatments as a Potential Seed Processing Technology

Plasma treatments are currently being assessed as a seed processing technology for agricultural purposes where seeds are typically subjected to pre-sowing treatments to improve the likelihood of timely and uniform germination. The aim of this review is to summarize the hypotheses and present the evidence to date of how plasma treatments affect seeds, considering that there is difficulty in standardizing the methodology in this interdisciplinary field given the plethora of variables in the experimental setup of the plasma device and handling of biological samples. The ever increasing interest for plasma agriculture drives the need for a review dedicated to seeds, which is understandable to an interdisciplinary audience of biologists and plasma physicists. Seeds are the first step of the agricultural cycle and at this stage, the plant can be given the highest probability of establishment, despite environmental conditions, to exploit the genetic potential of the seed. Furthermore, seedlings seem to be too sensitive to the oxidation of plasma and therefore, seeds seem to be the ideal target. This review intentionally does not include seed disinfection and sterilization due to already existing reviews. Instead, a summary of the mechanisms of how plasma may be affecting the seed and its germination and developmental properties will be provided and discussed.

“…Furthermore, cold plasma treatment also improves the nutrient content and physiological metabolism of seeds such as dehydrogenase activity, superoxide dismutase, peroxidase activities, photosynthetic pigments, photosynthetic efficiency, and nitrate reductase activity during germination process (Mujahid et al., 2020). Plasma treatment also helps to break down seed dormancy and germination property of quinoa seeds as well as non‐cereals like tomato, and grape buds (Mujahid et al., 2020). The physicochemical property of cereal grain is found to be improved after plasma treatment.…”

“…For instance, Los et al (2018) observed that wheat and barley treated with high voltage (80 kV) DBD-plasma in the closed system showed no changes in germination up to 5 min treatment, but they noted that direct application of DBD for 20 min decreased the germination rate. Furthermore, cold plasma treatment also improves the nutrient content and physiological metabolism of seeds such as dehydrogenase activity, superoxide dismutase, peroxidase activities, photosynthetic pigments, photosynthetic efficiency, and nitrate reductase activity during germination process (Mujahid et al, 2020). Plasma treatment also helps to break down seed dormancy and germination property of quinoa seeds as well as non-cereals like tomato, and grape buds (Mujahid et al, 2020).…”

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.
