Abstract :
Physical and electrical contact between liquid food and the metallic electrodes during the pulsed electric field process for microbial inactivation is unavoidable and causes some metallic ions to be released from the electrodes into the processed food. Coating the electrodes with corrosion-resistant materials is introduced to solve this problem. When the electrodes are made of titanium, the concentration of metal released is always below the detection limit.
