How do you authenticate green-plum-concrete and screen for adulteration?

Top authenticates by:

  • HPLC for organic acids (citric/malic) and GC for the fruity volatile fingerprint matched to the natural Prunus mume Siebold & Zucc. (green plum / Chinese plum) profile and the GC/MS fingerprint
  • GC/MS fingerprint plus targeted adulterant screening
  • Species + "Prunus mume Siebold & Zucc. (green plum / Chinese plum) 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.
