“…Dimensional characteristics of the electrodes and the electrical conductivity of liquid are the main parameters responsible for the electrical resistance. The electrical characteristics of electrodes are also affected by some other physical properties of the electrodes such as surface roughness and contamination by biological materials such as protein or fat deposits [26]. For collinear chamber configurations, numerical simulations and the experimental measurement of the voltage and current can be used to determine resistance [27].…”

<div style="text-align: justify;"><span style="font-family: 'Times New Roman', serif; font-size: 9pt;">Over the last couple of decades, pulsed electric field (PEF) attained substantial consideration in the food industry with an effort to generate replacements to conventional thermal treatment. It is recognised to produce secure and chill-stable liquid food samples with fresh and nutritional qualities. The uniform electric field in the treatment zone has been recognised as the main handling parameter. The design of the treatment chamber shows an essential impact on the effectiveness of the procedure by controlling homogenous treatment. This study revealed the homogeneity of the electric field strength of the different existing treatment chambers through COMSOL Multiphysics. It adopted a study to design a co-axial treatment chamber for continuous treatment of liquid samples. This research helps to take some fundamental designing steps for a new treatment chamber with a uniform distribution of the electric field.</span></div>

“…The pulse-treated sample of the cell culture medium was collected into 2 mL Eppendorf tubes, and the procedure was repeated until the amount of pulse-treated medium required for seeding the cells was collected (2 mL for each Petri dish). To avoid any influence on the cell viability of the increased medium temperature, which might occur due to the application of the pulse [49,50], after the exposure, the medium was allowed to reach room temperature before seeding the cells.…”

Cytotoxicity of a Cell Culture Medium Treated with a High-Voltage Pulse Using Stainless Steel Electrodes and the Role of Iron Ions

High-voltage pulses applied to a cell suspension cause not only cell membrane permeabilization, but a variety of electrolysis reactions to also occur at the electrode–solution interfaces. Here, the cytotoxicity of a culture medium treated by a single electric pulse and the role of the iron ions in this cytotoxicity were studied in vitro. The experiments were carried out on mouse hepatoma MH-22A, rat glioma C6, and Chinese hamster ovary cells. The cell culture medium treated with a high-voltage pulse was highly cytotoxic. All cells died in the medium treated by a single electric pulse with a duration of 2 ms and an amplitude of just 0.2 kV/cm. The medium treated with a shorter pulse was less cytotoxic. The cell viability was inversely proportional to the amount of electric charge that flowed through the solution. The amount of iron ions released from the stainless steel anode (> 0.5 mM) was enough to reduce cell viability. However, iron ions were not the sole reason of cell death. To kill all MH-22A and CHO cells, the concentration of Fe3+ ions in a medium of more than 2 mM was required.

“…1b and 1e, are usually applied in water and air disinfection applications [9]. The pulses of combined narrow and wide pulse durations, shown in Figs.1c and 1f, are recently proposed in [1], [5] and [10] and are preferred in safe food sterilization, without altering the food nutrition values and freshness quality [11]- [12].…”
