Is this green mandarin oil tested for heavy metals and pesticide residues?
Yes. Because green mandarin oil is a food-grade flavouring substance (GB 29938-2020, FEMA 3043), heavy-metal and pesticide testing is part of the standard release, with tighter limits available for cosmetics and food projects.
Testing Regime
| Contaminant group | Method | Typical limit |
|---|---|---|
| Lead (Pb) | ICP-MS | ≤ 5 mg/kg (food-grade); tighter on request |
| Arsenic (As) | ICP-MS | ≤ 2 mg/kg |
| Cadmium (Cd) | ICP-MS | ≤ 1 mg/kg |
| Mercury (Hg) | ICP-MS | ≤ 1 mg/kg |
| Organochlorine pesticides | GC-ECD | Below detection / market-specific MRLs |
| Organophosphorus & pyrethroid pesticides | GC-MS | Below detection / market-specific MRLs |
| Residual extraction solvent | GC-FID | None — cold pressing uses no extraction solvent |
- Orchards grown for flavouring follow Good Agricultural Practices; pesticide-use records are kept per field
- Citrus-specific residue checks (e.g., post-harvest dip residues) are covered by the market MRL where applicable
- For the EU and US cosmetic markets, results are reported against the corresponding pharmacopoeia or cosmetics directives
- Third-party testing by SGS or Intertek can be added for any destination market at cost
- If your customer needs an EU 2023/1545 allergen profile plus contaminant report in one document, we issue a combined dossier
