We studied the inactivation kinetics of Cronobacter sakazakii (CS) in infant formula subjected to radio frequency dielectric heating (RF) alone or sequential RF-UVC irradiation for 30 min. We used one linear model and two nonlinear models to fit the data and compared the results. Our findings revealed that CS was more susceptible to the combined treatment than to RF alone at the same temperature and that inactivation rate increased with increasing temperature. The sequential RF (90°C, 5 min) - UVC (25 min) treatment was the most effective at inactivating CS. The survival curves of CS were non-linear. …
