Study actual storage
A real-time plan follows the product under agreed conditions that reflect its intended storage. Refrigerated, ambient and frozen distribution each require their own defined study context.
Schedule meaningful pulls
Choose a baseline and subsequent time points around the proposed shelf life and expected changes. Include enough material for each analysis rather than repeatedly opening a single package.
Set review criteria
Identify the microbial, chemical and quality endpoints that will be assessed. Different products can fail for different reasons, so the same checklist is not sufficient for every food.
Use the findings
Review the full series, not only the last result. The conclusions apply to the formulation, packaging and storage studied. Significant changes may require additional work.
