Coriander Retained Samples: Keep a Usable Lot Reference

A jar of coriander on a buyer's desk is useful only if everyone can explain what it represents. Coriander retained samples should connect a purchase decision to an identifiable lot, a sampling event and an agreed purpose. Without that connection, a later comparison can produce two confident opinions about two different products.

For spice processors and importers, the practical question is how to preserve evidence that remains interpretable after delivery. This guide sets out a proposed buyer record, a custody arrangement and a sensible escalation sequence. These are commercial planning suggestions, not a universal sampling plan or an official inspection procedure.

Coriander retained samples need a defined purpose

Start by separating a sales sample from a lot reference. A sales sample might demonstrate a possible style or aroma. Unless its relationship to the offered lot is established, approving it should not be recorded as approval of every subsequent shipment.

A pre-dispatch sample can serve a different purpose: documenting the identified lot at an agreed point. An arrival sample records another event. If processing, treatment or repacking occurs between those events, preserve that information alongside the samples. Otherwise, a difference may be attributed to transport without evidence that the material started in the same condition.

The Codex General Guidelines on Sampling distinguish sampling plans from the physical act of taking material. They also explain why convenient sampling may fail to represent a lot. A beautifully sealed jar cannot correct an unsuitable selection process.

Agree the reference before the shipment leaves

Ask the responsible sampler or laboratory to propose the sampling method, required quantities and containers for the intended examinations. A sensory reference and a microbiological laboratory sample need not be interchangeable. Avoid prescribing one household container or one sample mass for every test.

The purchase file should answer four questions:

• Which lot or separately identified sublot does each sample represent?
• At what stage was it drawn, and was that before or after any declared treatment?
• Who selected, divided, sealed and dispatched the material?
• What question is the sample intended to answer if a concern arises?

For a shipment containing several lots, ask whether separate references are needed. Do not quietly replace them with an unrecorded mixture. That can make it impossible to identify which lot a later result concerns.

Build a sample identity card

Use a short record that travels with the reference and also remains in the order file. Suggested fields are the purchase reference, supplier lot, product form, sampling date and place, sampler, method reference, seal identifier and recipient. Add links to the corresponding certificate of analysis and any agreed specification revision.

Record the condition of the sample on receipt. A broken seal, unreadable code or unexplained delay deserves a note before the material is opened. This is a record of an exception, not an automatic conclusion that the shipment is defective.

Agree who holds each reference, who may authorize opening it and how an opening is logged. Storage conditions and the retention period should be agreed with the relevant technical parties for the product and intended tests. They should not be improvised from the expected vessel transit alone.

Hypothetical example: a blend processor's aroma complaint

Imagine a processor buys two identified lots of whole coriander for separate production runs. After delivery, the second run smells different during preparation. The buyer's cupboard contains a supplier's initial sales sample, but no record connects it to either shipment lot.

Comparing that sales sample with a scoop from the second production run cannot establish when the difference arose. The stronger starting point is the second lot's documented reference, its analysis, the arrival record and the processor's own handling history. If those records are incomplete, acknowledge the gap before assigning responsibility.

Use a staged review when results differ

First confirm identity: matching product, form, lot and sampling stage. Then check whether the results concern the same characteristic, analytical method and reporting basis. Send the original reports to the technical reviewer rather than retyping only the disputed number.

Next establish whether a reference remains sealed and suitable for the proposed examination. Agree the next laboratory instruction and the parties who will receive the result. Repeatedly testing convenient portions until a preferred answer appears does not resolve the underlying sampling question.

Keep commercial notices and contractual time limits separate from the laboratory timetable. Ask the contract owner to confirm required communications while technical review proceeds; this article does not establish claim deadlines or decide liability.

Key takeaways and the next enquiry

A useful retained sample has a known purpose, a traceable origin and a recorded history. Establish those elements before dispatch, and preserve separate lot identities when the enquiry requires them.
