Abstract:
Non-thermal plasmas (NTP) have been employed in many processes in order to modify surfaces of different materials, either as an etching tool, for surface activation and also for deposition of thin films and nanofabrication. In these applications mostly NTP at low-pressures have been used. Mostly usage of low-pressure NTP for these applications imposed a limitation to the type of material that could be treated and limited applications of technology to only on relatively dry materials. As NTP sources at atmospheric pressure are being developed, the number of plasma material processing applications is increasing. New fields for possible applications of NTP under atmospheric pressure sources emerge, such as medicine, biology and in the last years agriculture and food industry. NTP treatment can change the functionality and improve the rheological properties of food materials due to the radicals and ozone propagated oxidation of food components. Additionally, plasma-created reactive species have demonstrated the ability for toxins detoxification. Therefore, in this study, we investigated the effects of NTP treatments on mycotoxins of contaminated flour and demonstrate that the reduction of mycotoxins content in treated flour is depending on the type of the toxin and treatment conditions. The results of these determinations indicated a marked decrease of mycotoxins content, possibly through a reaction of mycotoxins ozonization.
