Pulsed electric field treatment using boron doped diamond electrodes

摘要

A treatment chamber 100 for a treatment apparatus for preserving pumpable food products in a pulsed electric field comprises an inlet 110 for receiving the food products, an outlet 120 for expelling the treated food products, a first electrode 130 abd a second electrode placed between the inlet and the outlet. The electrodes are electrically insulated from each other and being arranged such that upon application of a potential across the first electrode and the second electrode a food product in the treatment chamber is subjected to an electric field. The first and second electrodes are boron-doped diamond electrodes. Boron doped diamond electrodes are able to withstand high field strengths and pulsation frequencies and do not degrade to produce toxic degradation products.
