Food Shelf life Testing
Shelf-life is more than just an expiry date it represents the period during which a food product maintains its safety, quality, nutritional value, and sensory attributes under specified storage conditions. Accurate shelf-life determination ensures products remain safe for consumption, comply with regulations, and uphold consumer trust.
Eurofins provides scientifically validated shelf-life determination and verification services for all food categories. Our multidisciplinary approach integrates microbiological, chemical, physical, and sensory analyses, enhanced by predictive modeling and accelerated stability studies. We help manufacturers optimize formulations, packaging, and storage conditions to ensure consistent quality from production to consumption.
Understanding Shelf-Life and Its Determining Factors
Shelf-life depends on product composition, processing, and environmental factors. It is evaluated under real-time and accelerated conditions to assess deterioration kinetics and identify spoilage risks.
|
Factor |
Description |
Impact on Shelf-Life |
|
Microbial Growth |
Presence of bacteria, yeasts, or molds |
Spoilage, off-flavors, foodborne illness |
|
Chemical Reactions |
Oxidation, enzymatic activity, pH changes |
Nutrient loss, rancidity, discoloration |
|
Moisture & Water Activity (aᵥ) |
Migration or absorption during storage |
Texture degradation, microbial growth |
|
Temperature & Light Exposure |
Storage and transit conditions |
Accelerated spoilage or oxidation |
|
Packaging Integrity |
Barrier properties, permeability |
Contamination, moisture or oxygen ingress |
Eurofins evaluates these variables to accurately predict shelf-life performance under target market conditions.

Eurofins Analytical Testing Capabilities
Eurofins employs a robust suite of analytical and predictive tools for shelf-life validation:
Microbiological Analysis
- Total Plate Count (TPC), yeast & mold enumeration.
- Pathogen challenge tests (Listeria, Salmonella, E. coli, Bacillus spp.).
- Spoilage organism identification by MALDI-TOF.
Chemical and Physical Analysis
- Peroxide Value (PV), Acid Value (AV), and TBA tests for lipid oxidation.
- Nutrient stability: vitamin degradation, protein denaturation.
- Water activity (aᵥ), moisture content, pH, and texture profiling.
- Packaging permeability and oxygen transfer rate.
Sensory Evaluation
- Trained panel evaluation for aroma, taste, appearance, and texture.
- Statistical modeling to correlate consumer acceptability with analytical data.
Predictive Microbiology and Modeling
- Predictive modeling software (ComBase, DMFit) for microbial growth prediction.
- Kinetic degradation modeling for nutrient or quality loss.
