Metal release in a stainless steel pulsed electric field (PEF) system

This paper investigated the metal release in a stainless steel pulsed electric field (PEF) system by considering the effect on a real food product, in this case orange juice. This issue and the description about pulse shapes in Part I are of great importance for the commercialisation of the PEF technology. A relationship is determined between the dissolved metals in orange juice and the transferred charge. This parameter can be used during the development of larger PEF treatment systems for orange juice. For the described treatment system, a treatment chamber lifetime prediction is given that is based on the released metal concentrations. The metal concentrations are also compared to the Dutch and European legislation rules.
