Quick answer: A retained sample is a small portion of each production lot kept by the supplier, and often by the buyer, for a set period. If a complaint or question arises later, the retained sample can be tested to show what the product was like when it was shipped. Retained samples support quality investigations, audits and disputes. They should be labelled, sealed and stored under the same conditions as the product.
Key takeaways – Retained samples are kept from each lot. – They help investigate complaints and questions. – Store them sealed, labelled and in suitable conditions. – Keep them at least for the product’s shelf life.
Why keep retained samples?
When a customer reports a problem, such as off-flavour, colour difference or contamination, the supplier needs to know whether the issue started at production or later. Testing the retained sample from the same lot gives an answer. Food safety standards often expect suppliers to keep samples.
How much should be kept?
The amount depends on what tests may be needed. For coconut sugar, many companies keep enough for repeat testing of moisture, microbiology, sensory and sometimes contaminants. Common practice is from a few hundred grams to one kilogram per lot, depending on internal procedures and buyer requirements.
How should samples be stored?
| Requirement | Good practice |
|---|---|
| Container | Clean, sealed, food-grade bag or jar |
| Label | Product, lot number, production date, quantity |
| Conditions | Cool, dry, protected from light and odours |
| Location | Dedicated, organised sample store |
| Records | Logbook or system linking samples to lots |
How long should samples be kept?
At least until the end of the product’s shelf life, and often a little longer. Market specifications for coconut sugar often list shelf life of about 24 to 36 months. Buyer contracts may set specific retention times.
How are retained samples used?
- Complaints: compare the retained sample with the customer’s sample.
- Shelf-life checks: test how the product changes over time.
- Audits: show auditors that the system works.
- Disputes: provide evidence of the product’s condition at shipment.
- Training: use as reference samples for sensory panels.
Should buyers keep samples too?
Yes. Buyers often keep their own retained sample from each received lot. Comparing both sides’ samples gives a clearer picture if questions arise.
What about disposal?
When the retention period ends, dispose of samples in a controlled way and record the disposal. Do not use old samples as product.
