How do you authenticate longan-concrete and screen for adulteration?
Top authenticates by:
- HPLC for sugars and GC for the fruity-floral volatile fingerprint matched to the natural Dimocarpus longan Lour. (longan) profile and the GC/MS fingerprint
- GC/MS fingerprint plus targeted adulterant screening
- Species + "Dimocarpus longan Lour. (longan) species-specific raw material" declaration on COA
- 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.
