Sanitation of tomatoes based on a combined approach of washing process and pulsed light in conjunction with selected disinfectants

In this study, we evaluated the performance of a large-scale decontamination system based on a washing process in combination with pulsed light (PL) exposure and H2O2/chlorine. In order to identify optimum processing condition, we first evaluated the effect of single and combined PL treatments on the inactivation of Salmonella on grape tomatoes using a small sample size of 50 g. Two inoculation methods, spot and dip, were used to simulate...
