Ozone Generation using a Dielectric Barrier Discharge Reactor for Increasing Food Shelf Life

Abstract

Nowadays great attention has been paid to the DBD discharge on atmospheric pressure because of its wide application perspective in many industrial fields. This discharge is a little specific kind because one electrode is covered by a dielectric material, thereby preventing the discharge to move towards electrical breakdown. One of its most important applications is the production of ozone (o3) for air treatment specially dedicated to the food industry to extend the storage life of food products. The aim of this paper is to study and identify the set point of electrical parameters of DBD discharge for ozone generation using the Response Surface Modeling (RSM) method; the optimal values obtained are then applied in a system of conservation of food products. The experiments were carried out on a laboratory experimental bench. Obtained results pointed out that the investigated parameters of DBD have a significant effect not only on ozone production but also on prolonging the shelf life of food products.
