Extending the shelf life of foodstuffs: Disinfection of packaging with UV specialty lamps

Food manufacturers are increasingly choosing disinfection with ultraviolet light as a cost-effective and environmentally friendly alternative to conventional chemical processes.

Short-wave UV-C radiation, in particular, has an intensive bactericidal effect. Microorganisms such as viruses, bacteria and fungal spores are destroyed by UV radiation in a matter of seconds.

Already in use worldwide, UV disinfection modules from Heraeus Noblelight can be installed into existing filling machinery for dairy and beverage products. BlueLight UV disinfection modules are custom-built for the treatment of packaging and surfaces. Various shapes and sizes of containers for dairy products, as well as lids, sealing and packaging foils can be disinfected with UV radiation. UV disinfection inactivates up to 99.99% of total germs without slowing the machinery.

The UV modules are also suitable for combination treatment with UV and hydrogen peroxide (H2O2). The powerful systems produce cold UV radiation, disinfecting packaging material without heat.

The compact design makes it easy to retrofit BlueLight UV disinfection modules into existing plants. Heraeus offers UV disinfection modules in a range of sizes that can be adapted to suit the particular application.
