Unique Manuka Factor
UMF is a registered quality mark identifying Manuka honey that has the special natural property found only in some strains. The UMF grading system appraises the natural markers found in Manuka honey and assures purity and quality. UMF is one of a number of different grading systems adopted throughout the world. It is highly regarded and one of the most recognisable and well-known measures.
MGO stands for the natural chemical methylglyoxal, sometimes referred to as MG. Methylglyoxal is the naturally occurring compound found and identified in genuine New Zealand Manuka honey.
An extensive industry consultation was performed prior to the end of 2017 and the Ministry for Primary Industries (MPI) made its decision on the scientific definition of Manuka honey.
It states that four chemical markers from nectar and one DNA marker from Manuka pollen must be at a certain level to meet overseas export requirements. Rules were to apply from February 5th, 2018.
PURITI also decided to raise the bar over and above the MPI Manuka Honey Science Definition. The pass mark for all 4 chemical markers is set considerably higher for all PURITI products.
