Abstract

This study presents the effect of direct current (DC) electric field application on ice sterilization. The sample used was Escherichia coli (JM103) in a 0.001, 0.01, or 0.1 mol/L NaCl aqueous solution. The experimental sample was placed in a cuvette with parallel electrode plates (distance between electrodes: 1 mm) and then cooled at −30 °C or −80 °C for 40 min. After freezing, a 100 V DC voltage was applied to the sample in the freezer with a temperature of −30 °C or −80 °C. Consequently, the survival ratio of E. coli in all samples after freezing was lower than that before freezing due to the freezing injury. In conclusion, we found the bactericidal effect of the DC electric fields in the frozen 0.01 mol/L NaCl samples. © 2021 Institute of Electrical Engineers of Japan.
