“…According to Figure 8, untreated wheat seeds have a hydrophobic surface, as they presented an apparent water contact angle close to 120°, a value similar to that found by other authors. [ 18,23 ] Just after 10 s of plasma treatment, the apparent contact angle decreased noticeably to reach a value of 55°. A progressive further decrease in the apparent contact angle continued to be observed when increasing the treatment time to reach a very hydrophilic surface (i.e., apparent contact angle of 10° or less) after 900 s of plasma exposure.…”

“…[1][2][3][4][5][6][7][8][9][10][11] To overcome these issues, several studies have investigated the fast, nondestructive, and uniform plasma activation of different seeds such as wheat, quinoa, cotton, and many other plants. [3,5,6,10,[16][17][18][19][20][21][22] This modern practice has been demonstrated efficient for wheat seeds subjected to oxygenor nitrogen-containing plasmas in terms of enhanced wettability and increased germination capacity up to optimal treatment time, beyond which germination impairs. [10,19,23] Hence, plasma process parameters should be highly fine-tuned to generate the desirable chemical and morphological seed characteristics, triggering biostimulation.…”

“…[28] Different authors have pointed out that plasma treatments enhance the wheat seed hydrophilicity and the water-uptake velocity, thus reaching the critical water content required to trigger germination faster. [3,5,10,[18][19][20] Despite being recently investigated, the plasma-induced mechanisms underlying wheat germination enhancement are still vague, as no in-depth studies have been so far conducted on the specific chemical changes engendered on the outermost part of wheat seeds. Moreover, in addition to the seed surface properties, the environmental conditions surrounding the seed, particularly the critical irrigation state, also play an influential role in the water-uptake amount and kinetics.…”

Plasma treatment is increasingly being explored as an effective presowing treatment improving seed germination. This study examines the synergetic effect of the irrigation condition and the physicochemical surface properties of wheat seeds subjected to atmospheric dielectric barrier discharge plasma activation on their water uptake and germination. Extensive surface analysis revealed a remarkably enhanced wettability of plasma‐treated seeds due to the insertion of oxygen‐containing functionalities on their surface. However, long plasma exposures damaged the outermost layers of the pericarp due to a pronounced oxidative etching effect. Although the seed germination capacity was not affected by the plasma treatments, short plasma exposures were shown to enhance water uptake and accelerate seed germination, especially under water‐scarcity conditions.

“…[ 29 ] Thus, the majority of these studies reported on the change of the hydrophobicity and wettability of the grains exposed to plasma which was by a certain degree associated with CAP‐induced oxidation of the seed surface and resulted in the stimulation of germination. [ 9b,12 ] Velichko et al [ 30 ] used an argon radiofrequency atmospheric pressure plasma jet and direct air DBD for the treatment of wheat seeds, leading to 20%–30% increase in the water uptake of the grains as a result of the reduced contact angle. Wheat grains were also placed directly into the plasma phase generated with air atmospheric pressure DBD.…”

Mycotoxins, the toxic secondary metabolites produced by filamentous fungi, are found in up to 80% of global food and feed crops. Here, we report on the complete removal of aflatoxin B1 (AFB1) from the artificially contaminated corn kernels with an indirect cold atmospheric pressure plasma (CAP) treatment generated with a surface barrier discharge system working in ambient air. Surface analysis of the corn kernels revealed the presence of minor changes in the treated samples, indicating that indirect CAP treatments induced slight oxidation of the corn kernel surface. This study not only proposes CAP as an effective food processing method for the decontamination of mycotoxins but also presents the first step towards acceptance of CAP technology as a safe food processing method.

“…(2019). It was observed that germination and seedling growth in wheat seed were significantly improved by 20%–30% after plasma jet‐DBD treatment for a short time, compared to untreated samples (Velichko et al., 2019). Medium pressure (~10 torr) low‐frequency (3–5 kHz) glow discharge (LFGD) plasmas applied on wheat seeds increased the water absorption and provided 95%–100% seed germination.…”

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.
