Scientifically Defensible Validation & Shelf-Life Testing
Our PhD-led scientific team designs experimental protocols, manages sample execution through audited ISO/IEC 17025-accredited laboratory networks, and delivers comprehensive statistical reporting.
Microbiological Challenge Studies
Executed in strict compliance with NACMCF and Health Canada guidelines using multi-strain pathogen cocktails (Listeria monocytogenes, Salmonella enterica, Clostridium botulinum) under both optimal (4°C) and abused (7°C–10°C) temperature profiles across 150% of targeted shelf life.
What's Included
- Multi-strain pathogen cocktail inoculation
- Optimal (4°C) and abused (7°C–10°C) temperature profiles
- 150% of targeted commercial shelf life duration
- NACMCF and Health Canada guideline compliance
- Legally defensible statistical reporting
Molecular Diagnostics & Contamination Fingerprinting
PCR and droplet digital PCR (ddPCR) assays for absolute quantification of low-level target nucleic acid sequences, detecting viable but non-culturable (VBNC) pathogens and persistent plant biofilms.
What's Included
- Droplet digital PCR (ddPCR) absolute quantification
- Viable but non-culturable (VBNC) pathogen detection
- Persistent plant biofilm identification
- Contamination source fingerprinting
- Peer-reviewed methodology
Spoilage Identification & Predictive Growth Modeling
Genus- and species-level isolation of fungal and bacterial spoilage flora combined with mathematical kinetic modeling (modified Gompertz, Baranyi, and Ratkowsky models) to project lag-phase extensions.
What's Included
- Genus- and species-level spoilage organism isolation
- Modified Gompertz kinetic modeling
- Baranyi and Ratkowsky growth models
- Lag-phase extension projections
- Shelf-life scenario modeling
Physicochemical Matrix Optimization
High-precision water activity (aw) dew-point analysis and pH dissociation profiling to optimize natural preservative minimum inhibitory concentrations (MIC) within your specific food matrix.
What's Included
- High-precision water activity (aw) dew-point analysis
- pH dissociation profiling
- Minimum inhibitory concentration (MIC) optimization
- Matrix-specific formulation adjustment
- Processing parameter compatibility testing
