UV-C light has been used in the decontamination of air, surfaces and
water . Moreover, the food industry has recently displayed an increasing
interest in UV-C light for the hygienization of liquid and solid foodstuffs,
since UV-C radiation is capable of inactivating pathogenic and spoilage
bacteria while only minimally affecting the food's nutritional and sensorial
properties. Furthermore, it consumes less energy than other non thermal
food pasteurization technologies (Gayan, Serrano, Pagan,
Álvarez, & Condón, 2015; Geveke, 2005; Guerrero-Beltran &
Barbosa-Canovas, 2004). Since the key target of UV-C light is DNA,
the effect on cell envelopes is minimized.
