Various strategies are used to reduce postharvest cereal grain contaminants such as insect pests and fungal pathogens. Chemical and physical treatments are common management practices but may leave harmful chemical residues on grains or alter their nutrient content (particularly temperature treatments) and have other limitations. This review explores the recent literature regarding cold plasma, with emphasis on its efficacy for decontamination of postharvest cereal grain from biological contaminants. Cold plasma is an ionised gas containing reactive oxygen and nitrogen species, electrons and free radicals that are lethal to microorganisms and has the potential to decontaminate food surfaces and to increase shelf life. Studies conducted on rice, wheat, corn, barley and oats have demonstrated that cold plasma significantly reduced the amount of fungi, bacteria and their spores on grain surfaces. Cold plasma may also detoxify mycotoxins, and control insect pests. Evidence from various global studies demonstrates the potential use of cold plasma to manage postharvest fungi, mycotoxins and insect pests in Australian stored cereal grain.

The surfaces of two engineering polymers including polyamide 66 (PA66) and polytetrafluoroethylene (PTFE) were treated by diffuse coplanar surface barrier discharges in atmospheric air. We found that plasma treatment improved the adhesion of PA66 for either polymer/polymer or polymer/steel joints, however, it was selective for the investigated adhesive agents. For PTFE the adhesion was unaltered for plasma treatment regardless the type of used adhesive. Tribological properties were slightly improved for PA66, too. Both the friction coefficient and wear decreased. Significant changes, again, could not be detected for PTFE. The occurred variation in the adhesion and tribology was discussed on the basis of the occurred changes in surface chemistry, wettability and topography of the polymer surface.

Initial Degradation Rate

The degradation studies of picric acid (2,4,6-trinitrophenol, TNP) in water sample through a dielectric barrier discharge (DBD) of atmospheric air cold plasma was carried out. The used DBD reactor consisted of comprised two electrodes that were separated by using an insulating dielectric barrier having a electric discharge voltage varying from of 7.0 to 22.0 kV. The effects of the initial concentration of TNP on the initial degradation rate was investigated methodically. The initial degradation rate was determined experimentally by changing the initial concentrations of TNP between 91.02 and 210.17 mg/L using the DBD of cold air plasma. From experimental results, a kinetic equation for TNP degradation was established based on varying initial concentration as –R = 0.0252CTNP/(1+0.0076CTNP). When 0.0076CTNP << 1, the kinetics of TNP degradation complied with the pseudo-first-order reaction. For TNP degradation kinetics, such as ln (Ct/C0) = 0.0269t + 0.1605, ln (Ct/C0) = 0.0197t + 0.0792, and ln (Ct/C0) = 0.014t + 0.0623, the initial concentrations of TNP were 91.02, 153.3 and 210.17 mg/L, respectively. Moreover, the effect of initial concentration of TNP and the electric power on the degradation efficiency of TNP were determined.
