Relationship between treatment temperature and the time to inactivate 99.99% of the initial population (4D value) of Salmonella Typhimurium STCC 878 by heat (■), by heat after a UV treatment of 27.10 J ml−1 (●), and by both technologies applied simultaneously (▲). 4D values were calculated fitting survival curves with the Geeraerd and Van Impe inactivation model-fitting tool (GInaFiT). Survival curves to thermal treatments were obtained with a mixing method (thermoresistometer TR-SC).
