How do you authenticate red date concrete and screen for adulteration?

Top authenticates by:

  • total sugar + Brix + cAMP/polysaccharide profile matched to natural jujube fruit concentrate (the sugar/acid ratio and cAMP/polysaccharide assay are the signature; sugar-water or other fruit concentrate padding is screened by the ratio and missing cAMP/polysaccharide pattern)
  • patulin confirm (GB 2761 / GB 5009.185 not detected) — jujube is prone to moulding, a mandatory test
  • Species + "red date 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 sugar/acid/cAMP pattern.

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