Food safety, labelling and evidence-based shelf life
Last reviewed:
A sealed jar is not automatically shelf-stable. Safety comes from a validated recipe, controlled acidity or other hurdles, a suitable heat process, hygienic filling and verified storage.
Food safety
Use a validated product and process, then prove the controls are repeated.
- Register the food business before production starts.
- Fix the recipe by weight and specify the ingredient standards.
- Identify acidity, water activity, heat process, fill temperature, closure and storage as relevant controls.
- Use calibrated measuring equipment and document each batch.
- Check seal integrity, contamination, container suitability and cooling.
- Use laboratory or competent technical advice where the recipe or process falls outside established validated guidance.
- Create withdrawal and recall records that link every jar to a batch.
Official guidance
Labelling
The legal name and ingredient declaration must match the real recipe.
- Use the reserved name “jam,” “extra jam,” “jelly” or “marmalade” only if the product meets the applicable composition standard.
- Otherwise use an accurate descriptive name that does not mislead.
- List ingredients in descending order and emphasise regulated allergens.
- Declare net quantity, date mark, storage instructions, responsible operator and lot/batch details where required.
- Where required by jam rules, state fruit content or other prescribed particulars.
- Check the 2026 amended breakfast-food rules before approving a new honey-sweetened, reduced-sugar or novel preserve label.
Shelf life
Set two clear periods: unopened and after opening, where relevant.
Shelf life depends on recipe, process, jar, closure, headspace, contamination controls and storage. Sugar reduction, larger pieces, fresh herbs or a new jar can change the result.
- Define the expected unopened storage condition.
- Validate microbiological safety and quality using suitable evidence.
- Challenge the worst realistic batch and storage conditions.
- Set the best-before or use-by wording and an internal withdrawal date.
- State “refrigerate after opening” and an opened-use period only when both are justified.
- Revalidate after changing the recipe, supplier, jar size, cap, process or storage.
