The profile of temperature is shown for this technology (Fig. 4b).
During processing, the temperature was kept at room temperature
(20 C) and there was no important increase by the end of the
process, confirming that inactivation with ozone is a nonthermal
process.
A number of references mention that disinfection of produce
with chemical sanitizers or washing reduces the natural flora only
in 2e3 log reduction (Gil, Selma, López-Gálvez, & Allende, 2009),
which would not be enough when the concentration of pathogens
in the vegetables is higher.
