How do you authenticate pomelo-oil and screen for adulteration?

G4S authenticates by: (1) GC for limonene/nootkatone and the citrus volatile fingerprint matched to the natural Citrus grandis (L.) Osbeck (pomelo) profile and the GC/MS fingerprint; (2) GC/MS fingerprint plus targeted adulterant screening; (3) species + "Citrus grandis (L.) Osbeck (pomelo) species-specific raw material" declaration on COA; (4) heavy metals + microbiology per food-safety. Every lot ships with COA plus assay. We screen adulterants, heavy metals and solvent residue. Lots failing the natural profile or exceeding limits are blocked.
