UMF™ is the gold standard in grading methods and is backed by the New Zealand government or its verification of quality and potency.
There are a variety of grading systems and distinctions that exist in the marketplace today, but the most important seal to look for is UMF™, a quality trademark identifying natural, unadulterated Manuka Honey. The number represents three unique signature compounds which ensure purity and quality:
Methylglyoxal (MGO) is the compound chiefly responsible for the antibacterial property of Manuka Honey and forms the basis of the UMF™ grading system.
Leptosperin is found in the nectar of manuka flowers and is the most discerning characteristic to distinguish Manuka Honey from other honey types.
Hydroxymethylfurfural is also found in the nectar of manuka flowers and converts into MGO once the bees gather the nectar and turn it into honey.
