Quality & compliance
You can't audit a promise. You can audit a COA.
Anyone can say their extract is clean. What matters to your QA team is which method was used, what the limit was, and whether the number sits inside it. Here is exactly what we test, how, and how often.
In-process control
Quality control parameters
Five checks run on every single batch. The rest run on a defined frequency, and always ahead of an export consignment.
| Parameter | Method | Specification | Frequency |
|---|---|---|---|
| Appearance & colour | Visual inspection | Clear to slightly turbid; product-specific colour | Every batch |
| Refractive index | Abbe refractometer | Product-specific RI range | Every batch |
| Specific gravity | Hydrometer / density bottle | Product-specific SG range | Every batch |
| Moisture content | Karl Fischer titration | < 0.5% | Every batch |
| Extraction yield | Extract weight / raw material charged × 100 | Ginger ≥ 5.5%; product-specific | Every batch |
| Active content (e.g. gingerols) | HPLC | ≥ 20% total gingerols for ginger extract | Weekly, or on customer request |
| Heavy metals (Pb, Hg, As, Cd) | ICP-MS | Within EU / USFDA limits | Monthly, and on export consignments per the agreed sampling plan |
| Microbial count (TPC, E. coli, Salmonella) | Standard microbiological methods | As per FSSAI / FCC / EP standards | Monthly |
| Residual CO₂ solvent | Headspace GC | < 0.1% (food-safe threshold) | Every 10th batch |
| Pesticide residues | Multi-residue GC-MS | Compliant with EU MRL limits | Quarterly, and on export consignments per the agreed sampling plan |
| Certificate of Analysis | All parameters above | Full COA issued with the consignment | Every batch |
Heavy metals and pesticide residues are instrumental tests run at an accredited lab, so the sampling plan for export consignments is fixed with you in the specification — by consignment, by campaign, or by lot size, whichever your market requires. Tell us what your importer or customs authority expects and we'll work to it.
Need a parameter that isn't on this list — an ICH residual solvent panel, a specific allergen declaration, an EP or USP monograph assay? Tell us at enquiry stage and we'll confirm whether we run it in-house or through our accredited partner lab.
In the lab
What sits behind the numbers
Our in-house lab handles routine release testing — physical parameters, moisture, yield and identity. Instrumental work that requires accreditation for export documentation goes to a NABL-accredited partner laboratory, so the certificate carries third-party weight where your market needs it.
The QA function reports to the partners, not to production. That's deliberate: the person who can hold a batch shouldn't report to the person whose numbers depend on releasing it.

Back to the lot, back to the field
Batch identity
Every batch carries a unique number tying it to the raw material lot, extraction parameters, operator, date and analytical results. Retained samples are held against every batch.
Raw material lot
Incoming material is logged against supplier, region and season. Where we buy through FPOs and cooperatives, that traces back further than a broker purchase ever could.
Audit access
Buyers and third-party auditors are welcome at the plant. Batch records, calibration records and analytical files are available for review as part of your qualification process.
Send us your specification.
If you have a standard spec sheet or a supplier qualification questionnaire, send it across. We'll fill it in properly and tell you where we can and can't meet it.
