Manufacturers are responsible for determining the shelf-life of foods they produce. Predictive models can help determine shelf-life but laboratory testing of microbiological, chemical or sensory indicators within a food over time is often necessary.


Our custom-designed shelf-life or stability studies enable the determination of a product’s use-by date. This service is needed for new product formulations, to verify a new production or storage method, or a change in distribution conditions.  Studies of this type are designed to help ensure quality throughout the lifecycle of your product.

Mérieux NutriSciences takes a holistic approach to shelf life testing that provides insight into all aspects of the food. Our experts will design a robust study that encompasses all applicable testing. For many products this will be a combination of microbiological, chemical, and sensory testing. All aspects are considered when determining the shelf life of a product. In many cases this testing can be conducted at real-time and accelerated conditions.  

Testing methods include but are not limited to:

  • Organoleptic parameters: appearance, color, odor, flavor
  • Texture using a texture analyzer
  • Consumer Acceptability
  • Physical-chemical parameters: pH value, viscosity, density, emulsion stability
  • Microbiological parameters: microbial count
  • Lipid oxidation
  • Nutrient stability
