SCP-010 — Turmeric Quality Protocol

Revision date: 2026-09-01

ShankuChakra recommended operational protocol — this is not an official government or international standard.

Purpose

To provide a structured quality-verification process specific to turmeric shipments, given the product-specific parameters (curcumin content, colour, moisture) that most influence buyer acceptance.

Scope

Applies to turmeric shipments, whole finger or powder, from sample approval through pre-shipment inspection.

Definitions

Curcumin content
The percentage of curcumin (the primary pigment compound) in turmeric, commonly used as a quality and pricing benchmark.

Required Information

  • Agreed minimum curcumin content
  • Finger vs. powder requirement
  • Moisture and foreign matter limits
  • Mesh size, if powder

Procedure

  1. Confirm the buyer's required minimum curcumin content in writing as part of the product specification — this varies by application and should not be assumed.
  2. Confirm finger vs. powder requirement, and mesh size if powder, as these affect processing and packaging decisions.
  3. Test the approved sample for curcumin content, moisture and foreign matter before buyer sign-off (see the Sample Approval Protocol).
  4. At pre-shipment stage, re-test a representative sample from the packed consignment for the same parameters and compare to the approved reference sample.
  5. Document any deviation from the agreed curcumin content or other parameters and resolve with the buyer before sealing the shipment.

Checklist

  • Minimum curcumin content agreed in writing
  • Finger/powder and mesh size (if applicable) confirmed
  • Moisture and foreign matter tested against agreed limits
  • Pre-shipment sample compared against approved reference sample

Documents Required

  • Product specification sheet
  • Sample test results (curcumin, moisture, foreign matter)
  • Pre-shipment inspection report

Risks

  • Curcumin content below the agreed minimum discovered only after shipment
  • Mismatched finger/powder or mesh size relative to buyer's processing needs
  • Moisture levels increasing quality-deterioration risk during transit

Common Mistakes

  • Agreeing to supply turmeric without a specific curcumin percentage in writing
  • Not confirming mesh size for powder orders, leading to a product unsuitable for the buyer's processing line
  • Skipping re-testing of curcumin content at the pre-shipment stage

Verification Points

  • Is the minimum curcumin content documented as a specific figure, tested and confirmed at pre-shipment?
  • Does the finger/powder form and mesh size match what the buyer specified?
  • Are moisture and foreign matter within the agreed limits at the pre-shipment sample stage?
