How do you authenticate hawthorn concrete and screen for adulteration?

Top authenticates by:

  • total acid + Brix + total-flavonoids profile matched to natural hawthorn fruit concentrate (the malic/citric acid ratio and flavonoid HPLC, e.g., vitexin/hyperoside, are the signature; sugar-water or other fruit concentrate padding is screened by the acid/sugar ratio and missing flavonoid pattern)
  • patulin confirm (GB 2761 / GB 5009.185 not detected) — a hawthorn-class mandatory test
  • Species + "hawthorn fruit / aqueous concentrate" declaration on COA
  • Heavy metals + microbiology per food-safety.

Every lot ships with COA plus assay. We screen sugar-water dilution / other-fruit padding / over-dilution by the acid/sugar/flavonoid pattern.

Lots failing the natural hawthorn profile or exceeding patulin are blocked.
