UMF™ Rating System

The Significance of UMF™ Rating

Methyl Glyoxal (MGO) Efficacy Rating

Methylglyoxal (MGO) imparts Manuka honey with its unique antibacterial properties. The higher the MGO content, the stronger the antibacterial effect. The UMF™ certification mark indicates that the honey contains this specific active ingredient.

Authenticity Verification of Leptosperin

Leptosperin is unique to Manuka nectar, ensuring the honey's authenticity. Its anti-inflammatory properties increase with higher UMF™ ratings.

Dihydroxyacetone (DHA) Shelf Life Guarantee

Dihydroxyacetone (DHA) converts into methylglyoxal (MGO) within honey. The higher the DHA content, the longer the efficacy of methylglyoxal persists. Honey certified with the UMF™ rating must contain at least 70mg/kg of this compound.

Hydroxymethylfurfural (HMF) Freshness Indicator

Hydroxymethylfurfural (HMF) testing ensures that Manuka honey has not been subjected to excessive heating or prolonged storage, thereby preserving its unique properties.
