Process validation

Process validation with micro-organisms

When safeguarding against microbiological risks in production processes, again it’s all about the details: knowing precisely, measuring precisely, and intervening in the right place with the right resources to remove a microbiological risk.

In addition to our high-end specialist calculations, our in-house strain collection includes an extensive compilation of pathogenic and non-pathogenic micro-organisms we deploy in various challenge tests.

25% energy cost savings

We have realised significant energy costs savings for a producer of products with a long shelf life by calculating the effectiveness of their pasteurisation process first. We have continued to deploy a customised challenge test using a micro-organism specific to this combination of product and process. The challenge test demonstrated that our calculations were correct: the pasteurisation process could be shortened by 25%.


Process validation food production processes

In translating our knowledge into practical advice, we are inspired by a quote attributed to Goethe: “Knowing is not enough; we must apply".


On-site process validation of heating processes with surrogate bacteria

We use harmless surrogates for pathogenic bacteria such as Salmonella SSP and Listeria monocytogenes for the on-site validation of heating processes. These surrogate bacteria have identical properties to the pathogenic bacteria, but are completely harmless. The standards we use for validating heating processes with surrogates for pathogenic micro-organisms comply with all nationally and internationally accepted standards.
