UVC Effectiveness on Wood Barrels
Sanitizing Wood Barrels
Bluemorph has also had third party testing of the sanitizing ability of UVC on wood. Germicidal UV light (254 nm-UVC) is a technology that has been FDA approved for the decontamination of food and food contact surfaces (U.S. FDA 2000). As such it has demonstrated effectiveness in the log reduction of microorganisms on porous surfaces.
99% less bacteria in 2 minutes:
Our studies performed by Microbiology Quality Associates (MQA), demonstrated at greater than 99% (log 2.2) microorganism reduction after a 2 minute exposure with the UV55.
4.1 Log reduction in 12 minutes:
Our studies showed a 4.1 log reduction after 12 minutes of exposure to the UV55 device.
Accurate testing methods:
The UV55 was placed at a distance equivalent to that when applied directly through the bung hole of a barrel to simulate actual use.
Studies were performed in a controlled environment on oak stays taken from a barrel.
