University of California, Riverside researchers have identified key chemical reactions that occur when UV light is used to break down PFAS “forever chemicals” in water, which could inform the development and optimization of PFAS treatment technologies, or even more degradable fluorinated compounds.

Supporting routine laboratory testing, the GENESYS G5 series features an expanded software ecosystem with optional application-specific packages, including guided workflows and preconfigured methods intended to reduce setup time and improve consistency.

A new study demonstrated the efficacy of far-UV-C light at 222 nm for inactivating human norovirus on surfaces. As it is safe for humans, researchers believe UV-C 222 could enable real-time, continuous disinfection in enclosed foodservice settings and food processing environments.

Although UV-C was effective against Salmonella, E. coli, and Listeria monocytogenes under most conditions, pathogen regrowth during refrigerated storage was significant. The findings suggest UV-C may be a useful post-harvest intervention when used in combination with other measures.  

The pulsed light disinfection system is engineered for food processing and packaging environments, with a range of applications from direct irradiation of foodstuffs to package disinfection.

Addressing the need for efficient, inexpensive, and sustainable PFAS defluorination techniques, researchers from Ritsumeikan University, Japan have demonstrated the promise of near-UV light plus ligand-capped zinc oxide (ZnO) nanocrystals as a possible solution to PFAS recycling and remediation challenges.

Hydroxyl radicals offer an effective, safe, and scalable approach to food plant hygiene and food safety. This outcome can be achieved by devices that use ultraviolet (UV) energy to generate hydroxyls from water vapor, turning the ambient air into a mechanism for cleaning. 

Tebots Inc. has designed a UV disinfection station called POZ that addresses the limitations of existing devices that have prevented the technology’s adoption by the foodservice industry.

Biotech group Novozymes is making the change from classic filtration of its industrial enzyme liquids to a raslysation system from Danish company Lyras, which inactivates microbial contaminants in liquid foods using ultraviolet (UV) technology. Raslysation can be used as a substitute for the pasteurization of foods such as brine, whey, juice, iced tea, and many other liquids.  

Researchers at BSC Electronics in Perth, Australia have developed a berry-harvesting robot that can kill fungi on the fruits it picks by using ultraviolet (UV) light.
