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
