The Microbiological Challenge Testing : in-line microbiological qualification
How to make sure your Claranor unit is performing well ?
We have a continuous scientific collaboration with world class laboratories like INRA, Fraunhofer IVV, CNRS ... to improve the knowledge on our technology.
We also perform with our microbiologists in-line testing in your facility to validate the efficiency of your equipment in the form of Microbiological Challenge Testing.
Objective of the Microbiological Challenge Testing (MCT) :
Demonstrate the efficiency of the Pulsed ligth unit installed on the filling line.
- Perform the MCT in industrial conditions :
- real running configuration
- nominal line speed
- meet the customer requirement in terms of log-reduction of test micro-organism.
Principle of the MCT :
- Samples of packaging are inoculated beforehand with the reference microorganism
- These samples are placed on the line, under operating conditions, and treated by the Claranor Pulsed light equipment
- They are removed from the line and analyzed, looking for surviving microorganisms, in order to assess the log reduction achieved.
How can we ensure neutrality of results :
The tests are carried out :
- with the assistance of an external laboratory for the inoculation of the packaging, and carrying out the analyses.
- aligned with the VDMA (German Engineering Federation) recommandations.
- The tests must demonstrate the consistency of the results under operating conditions with those achieved under static conditions in the context of pre-sales tests.
