UMF is a rating comprised of four components
MGO FOR POTENCY - Methylglyoxal, is measured and included within the UMF™ guarantee meaning that you can be sure that Manuka honey bearing the UMF™ mark contains the special activity.
LEPTOSPERIN FOR AUTHENTICITY - Leptosperin is a compound found only in manuka flower nectar and can only be created by nature. Measuring this unique component ensures the authenticity of manuka honey. Laboratory research also shows leptosperin content has anti-inflammatory properties that grow as the UMF™ scale increases.
DHA FOR SHELF LIFE - Dihydroxyacetone (as it’s known to us) is slowly converted to MGO in healthy living honey. The higher the DHA content, the longer the life of the MGO content in your manuka honey – which is why the best manuka honey must have more than 70 mg/kg DHA to be UMF™ certified.
HMF FOR FRESHNESS - We test for hydroxymethylfurfural, since this long-named compound assures honey has not been overheated or stored too long, and is in the best condition to maintain the unique blend of living properties in manuka honey as promised by Rare New Zealand.
