Challenges of Far-UVC222nm radiation for food safety applications

Résumé fourni par la source

This work has reviewed the recent research progress in the utilisation of filtered Far-UVC lamps, predominantly KrCl excimer lamp emitting at 222 nm as disinfection applications. This review suggests inconsistent effectiveness of Far-UVC radiation against various microbial targets, largely influenced by light penetration and light absorption coefficients. According to current evidence, there is very limited progress in developing reliable Far-UVC lamps for long-term use in real world, resulting in technically constrained applications. The microbiological data further reveals that the technology's disinfecting capability is limited against biofilms, bacterial spores, and fungi due to their resilient structural and life cycle features. Current limitations in efficacy consistency and light source technology preclude Far-UVC from serving as a direct substitute for conventional UVC. However, its outstanding safety profile promise the technology possibly viable as a surface and air disinfection option, even when workers are present. Scientific evidence suggests that combining Far-UVC 222nm with other antimicrobial agents could enhance its effectiveness in food safety. Additionally, understanding the antimicrobial mechanisms of Far-UVC and bacterial tolerance to its exposure is crucial for optimizing disinfection practices and improving decontamination strategies. This review serves as a valuable reference for developing tailored solutions in industry-driven research and development.
