Low concentration electrolyzed water (LcEW) has been proved to be an effective sanitizer against pathogens in cell suspensions as well as pathogens and spoilage organisms attached to vegetables, poultry and meat. In this study, effect of current, electrolysis time and salt concentration on physical properties (pH, ORP and ACC) and inactivation efficacy of LcEW was monitored. Pure cultures of Escherichia coli O157:H7 and Listeria monocytogenes were prepared and exposure treatment was performed for bacteria inactivation study in cell suspensions at room temperature (23±2°C). Our results showed increased reduction of both pathogens with the increase in current. Changes of current also affected the ACC, pH and ORP values of the tested solution. Values of ACC, pH and ORP were increased with the increase in current. Log reduction of 4.9–5.6logCFU/mL for both pathogens was achieved when the current …
