Migration of electrode material during food processing by high-field pulses

Migration of the electrode material into the liquid food while being processed by high-field pulses represents one of the challenges against the commercialization of such non-thermal preservation technique. This paper investigates the effectiveness of controlling the electrodes´ double-layer discharging scheme. By adopting a forced double-layer discharging scheme, the migration is noticeably reduced and reaches an entire elimination if the operating frequency is further optimized. Electrode material is not migrating from both electrodes at the same rate; hence, coating only one electrode may be efficient and feasible.
