What defines the composition of pomelo-oil?
It is a citrus terpene oil (d-limonene dominant, with nootkatone and aldehyde/fresh top-notes) whose identity markers are d-limonene (key), with nootkatone, citral, aldehydes and fresh citrus volatiles. G4S fingerprints GC for limonene/nootkatone and the citrus volatile fingerprint as authenticity/quality markers. G4S fingerprints the citrus volatile profile and screens for synthetic citrus compounds or adulteration. Each COA reports relative density, refractive index, optical rotation, aldehyde content, heavy metals and micro; the identity is the natural Citrus grandis (L.) Osbeck (pomelo) profile, not a single volatile oil.
