Inactivation of bacterial spores by UV-C light
Innovative Food Science & Emerging Technologies, 2013 This investigation evaluates the ability of UV light to inactivate bacterial spores of interest for food preservation. It also evaluates the effect of the absorptivity of the treatment medium on UV lethality and the effect of the simultaneous or sequential combination of UV light and mild heating. A UV dose of 23.72 J/mL reached 2.25, 2.93, 3.24, 3.85,
