خلاصه مقاله:
Food contaminants are challenging the food industry due to the inefficiency of conventional decontamination techniques. Cold plasma as an emerging technique for the degradation of food contaminants attracted notable attention. The current study overviews the plasma-induced degradation of food contaminants, discusses the mechanisms involved, points its benefits and drawbacks out, highlights the research needed in this area, and explores future trends. According to the literature, cold plasma efficiently degraded many common pesticides (e.g. parathion, paraoxon, omethoate, dichlorvos, malathion, azoxystrobin, cyprodinil, fludioxonil, cypermethrin, and chlorpyrifos) and food allergens (e.g. tropomyosin, b-conglycinin, glycinin, trypsin inhibitor, and Kunitztype trypsin inhibitor). Climate change increases the need for effective and sustainable technologies in food and agriculture. Plasma-activated water (PAW) emerges as a green and sustainable technology in food processing and production. Synergy of a myriad of reactive oxygen and nitrogen species (RNOS) in PAW contributes to desirable properties of PAW. Compared to conventional methods, PAW is fast and effective for various products, not limited by the volume or shape of the treated samples. In this review, we will first introduce the fundamentals on plasma generation, physicochemical properties and characterization of PAW. Among various approaches for activation improvement, we highlight a recent progress in improving the cold plasma activation by microbubbles. Then we critically review the treatment conditions by PAW, and effectiveness of PAW for bio-film removal, food processing, plant growth in agriculture, and environment. As the research output on PAW is expanding exponentially, this review focuses on the work published within the last two years (۲۰۲۰-۲۰۲۱) to summarize the current understanding of the principles of the effects from PAW and to reflect potentials of PAW in applications for the food science and technology
