Electrolyzed water Escherichia coli O157:H7 Fresh-cut Process wash water Cross-contaminationResumen
Electrolyzed water (EW) is known by its bactericidal efficacy and capability to oxidize organic matter. The
present research evaluated the efficacy of recently developed electrolytic cells able to generate higher
concentration of reactive oxygen species using lower power and salt concentration than conventional
cells. This study tested the inactivation of Escherichia coli O157:H7, the organic matter depletion and
trihalomethane (THM) generation by EW in process wash water under dynamic conditions. To achieve
this, clean tap water was continuously added up to 60 min with artificial process water with high
chemical oxygen demand (COD) inoculated with E. coli O157:H7, in experiments performed in a pilot
plant that recirculated water through one electrolytic cell. Plate counts of E. coli O157:H7, COD, THMs,
free, combined and total chlorine, pH, temperature and oxidation-reduction potential were determined.
Results indicate that the novel electrolysis system combined with minimal ...
