How do you guarantee purity and authenticity of pomelo-oil?

Authenticity is guaranteed by (1) Q/XXXX conformance and (2) per-batch GC for limonene/nootkatone and the citrus volatile fingerprint plus GC/MS fingerprint plus targeted adulterant screening plus the COA species + "Citrus grandis (L.) Osbeck (pomelo) species-specific raw material" declaration. G4S does not spike with cheaper substitutes or synthetic mimics. The GC for limonene/nootkatone and the citrus volatile fingerprint is the authenticity proof. Lots failing the profile or the limits are blocked. For high-assurance needs we offer third-party verification. Purity claims always tie back to the lot's own data — no unsupported matches-standard language.
