Description: Cold Plasma is an emerging field of study in nonthermal processing of food materials. Apart from effective decontamination of food materials, it is also proven to be effective in inactivation of enzymes, changing the functional properties of food and removal of food pesticide residues without altering the quality of food material. Among the various cold plasma or nonthermal plasma systems, Dielectric Barrier Discharge (DBD) is preferred over the other discharge processes as thermal effects are negligible and it is a simpler and more energy efficient method. In this study, a plate type dielectric barrier discharge reactor was designed to treat liquid food materials. Copper foil was used as the electrode material and both the electrodes were covered with a dielectric barrier of 2 mm glass plates. The discharge gap was fixed as at 4 mm and DBD was powered by high voltage generator which can deliver the output in the range of 1-40kV (20kV peak-peak) and 20 kHz to 70 kHz frequency. Argon and atmospheric air were used as carrier gas to produce the nonthermal plasma.
