Cold Plasma for Food Processing works based on a novel non-thermal food processing technology that uses energetic and reactive gases for mild surface decontamination of foods and packaging materials. In this system, dielectric barrier discharge (DBD) is used as a common method for generation of non-thermal plasma. DBD is electrical discharge between two electrodes which at least one of them is covered by an insulating dielectric barrier. Applying high voltage alternating current leads to the non-thermal DBD plasma generation at atmospheric pressure.
