About UMF™ & MGO™
If you have been trying to assess the strength of Manuka Honey products, you may have noticed two different labels on the honey containers: one is UMF, the other is MGO.
This PORRO UMF™ 10+ / MGO™ 263+ Manuka Honey is certified to contain at least UMF™ 10 of Leptosperin / 263mg/kg of methylglyoxal, a naturally occurring compound found in significant quantities in manuka honey.
What is UMF
UMF stands for ‘Unique Manuka Factor’ and it is an internationally registered trademark that can be used only by licensed users who meet set criteria which include auditing and monitoring to ensure the product is natural, unadulterated, Manuka honey that has the unique non-peroxide antibacterial activity and is true-to-label claim.
Manuka Honey is independently tested in an accredited laboratory for its antibacterial UMF®. The UMF rating system was developed to measure the activity level of Manuka Honeys. The ideal UMF rating varies depending on your purpose.
Rather than measuring the methylglyoxal content like the MGO methodology, the UMF rating actually tests the antibacterial performance of a honey and compares it to phenol, a disinfectant.
What is MGO
Methylglyoxal is a compound found in the pollen of the Manuka tree’s flowers. MGO ratings refer to the level of Methylglyoxal in the honey.
Methylglyoxal is a marker of Manuka honey but it does not cause the non-peroxide activity. The higher the MGO™ rating in Manuka honey the higher the level of anti-bacterial activity in the honey.
Summary of UMF and MGO Manuka Honey
UMF and MGO ratings are both used to indicate the antibacterial strength of Manuka Honey in different ways, however there is a relationship between the level of Methylglyoxal and the Non Perocide Activity (as measured by the UMF).
