Shelf Life Prediction & Stability Analysis
Predict shelf life and identify degradation patterns from stability test data
What You Can Do
You can systematically evaluate accelerated aging studies (Arrhenius, humidity chamber, ASLT protocols) and extrapolate results to real-world ambient conditions. Claude helps you extract degradation patterns from multiple test scenarios, quantify safety margins, and build scientifically defensible shelf life predictions that satisfy regulatory requirements for FDA, EFSA, FSSAI, and other food authorities.
Features
Example Output
Example 1: Accelerated Test Analysis
Input: Moisture content data from humidity chamber testing (25°C/60% RH, 30°C/65% RH, 40°C/75% RH) measured over 12 weeks.
Output:
- Degradation rate constant at each condition (0.8%, 1.4%, 2.1% moisture gain per week)
- Predicted moisture at ambient (20°C/50% RH) after 24 months: 2.3% (±0.4%)
- Recommended shelf life: 18 months with 30% safety margin
- Critical control point: packaging seal integrity
Example 2: Sensory + Chemical Correlation
Input: Rancidity scores from sensory panels + peroxide values from chemical analysis across time/temperature.
Output:
- Detection threshold identified at 15 meq O₂/kg
- Time-to-threshold predictions at 5°C, 20°C, 30°C
- Ambient shelf life estimate: 24 months before sensory defect threshold
- Recommended storage: 20°C or below

You might also like
You can submit marketing copy, label claims, or advertising language and receive a structured compliance assessment that maps claims against FDA/FTC guidance, state regulations, and case law. The skill identifies claim type (health claim, structure-function claim, comparative claim, etc.), flags regulatory risks across jurisdictions, assesses substantiation strength, and recommends revisions to reduce enforcement exposure. This accelerates claim review workflows and prevents costly post-launch violations.

You can evaluate packaging solutions across multiple critical dimensions simultaneously. Claude analyzes material compatibility with specific food products, verifies compliance with FDA, EU, and international food contact regulations, calculates environmental impact and identifies sustainable alternatives, models barrier properties against oxygen/moisture/light penetration, estimates lifecycle costs, and generates technical documentation for suppliers and regulatory submissions. This integrated approach helps you make packaging decisions that protect product quality while meeting sustainability and budget requirements.
