Manuka Honey Rating System
Don’t get ripped off next time you go to purchase Manuka Honey. Many customers over pay for their Manuka Honey simply because they don’t know which products are authentic and genuine and worth the extra price. A quality Manuka Honey Rating System would definitely help people out here. Join us as we attempt to explain the two most common rating systems used to identify the quality level of Manuka Honey.
This chart will help you next time you go to make a purchasing decision, because you will know that the higher number is worth the extra money. Don’t get ripped off ever again!
Unique Manuka Factor (UMF) Honey rating system
There are two main Industry Rating Systems used today. The first one is called the Unique Manuka Factor (UMF) Honey rating system. It is an international trademarked rating system owned by the Unique Manuka Factor Honey Association.
The New Zealand producer needs to pay for an independent laboratory test to prove the purity and quality of the Manuka Honey contained in the jar. These include: the key markers of Leptosperin, Hydroxymethylfurfural (DHA) and Methylglyoxal. (source: http://www.umf.org.nz)
The UMF rating system tests the level of antibacterial performance of raw Manuka honey and compares it to a known disinfectant – phenol. This means that a UMF rating of 20+ is equivalent in strength to a 20% solution of phenol.
In order for a jar of Manuka Honey to be considered “active”, it must have a UMF of 10+ (source: Aliveplushoney, 2017).
Methylglyoxal Rating System MG or MGO
The MGO rating is a trademarked measure of the Methylglyoxal content of Manuka honey. The trademark owners are Manuka Health New Zealand Ltd. Industry competitors often use the generic term MG to represent the levels of Methylglyoxal found in their honey. The MGO rating (or MG rating) measures the levels of Methylglyoxal content ONLY and it does NOT measure the levels of Leptosperin or Hydroxymethylfurfural (DHA).

Welcome to Manuka Natural in New Zealand. I am Bill Gluyas and in an earlier video I mentioned the relationship between the compound Methylglyoxal referred to on some Manuka Honey labels as MGO and the longer standing method of interpreting the antimicrobial activity of Manuka Honey, UMF or Unique Manuka Factor.
Now today, I have drawn a small graph, its just indicative only. It gives us the relationship of the quantity of Methylglyoxal in Manuka Honey and the UMF Rating.
So you can see here that if we had a UMF level of for example of UMF 10+, it would be somewhat similar to around about 200 to 250 on the scale of Methylglyoxal which is measured in milligrams per kilogram of honey.
It’s not a linear, its not a straight line graph. As the UMF level of certification increases upto say UMF 25+, which is really quite rare, the proportion of Methylglyoxal is (
somewhat lower). Well it has to be so much higher in fact to reach that 25 UMF+ level.
Methylglyoxal is not the only compound that is responsible for the antimicrobial properties of Manuka Honey and it is only a measure of the quantity or the concentration of Methylglyoxal in the honey. Not totally, the antimicrobial properties or the antimicrobial effect of the honey in total.
UMF is a measure of how effective it is against certain bacteria. Methylglyoxal is a measure of the concentration of Methylglyoxal compound in the honey.
