Mérieux NutriSciences uses predictive modelling tools to predict the growth profile of a microorganism in the conditions chosen by the operator. This approach associates a growth profile with each combination of intrinsic (i.e., pH, water activity, preservatives) or extrinsic (i.e., humidity, light, temperature) parameters. Furthermore real time time inoculation studies are available to confirm predictive models.

Challenge studies performed in the laboratory can help ensure the microbiological safety of your products. This experimental technique consists in inoculating a known concentration of a microorganism into a product and following its development through use of a specific protocol, such as the standard protocol published by the NACMCF.

Our Challenge tests present the following benefits:
-    Classification of products according to the pathogen growth risk
-    Evaluation of risks and determination of critical points within the HACCP approach
-    Determination of criteria for acceptable levels of pathogenic organisms
