Shelf-Life Testing for Powdered Supplements
Share
Powder shelf life should be supported by a product-specific testing programme in the intended packaging. Being dry is not sufficient evidence of a particular storage period. Ingredient stability, moisture uptake, sensory changes and applicable safety or quality requirements need assessment together.
Which changes should the testing plan consider?
Relevant observations may include caking, colour, odour, flavour, flow and ingredient or nutrient stability. Microbiological assessment depends on the formula and process. Choose methods and acceptance criteria with qualified specialists so the programme answers the product’s actual risks.
Why test the final packaging?
A closure or film’s ability to protect the contents affects storage behaviour. Opening a multi-serve pack repeatedly introduces a different use pattern from a sealed sachet. Confirm the pack, fill amount, storage instructions and any in-use assessment before relying on the results.
How does testing connect to date labels?
For foods, FSANZ distinguishes use-by dates related to safety from best-before dates related to quality. The manufacturer is responsible for determining the appropriate date marking. Do not assign a universal 12-, 24- or 36-month shelf life solely because similar products use it; document the supporting assessment and its limitations.
What should you include in the project brief?
- Final formula and ingredient specifications.
- Final pack and storage conditions.
- Chemical, sensory, physical and microbiological checks as relevant.
- Observation schedule and agreed pass criteria.
- Date-marking rationale, instructions and ongoing review.
