The calculation is based on the published data (*) where UMF and Methylglyoxal concentrations are measured in a series of honey samples. These calculated values \u200b\u200band test method are not accredited by IANZ and do not imply that the honey is or is not Manuka honey. UMF values \u200b\u200bof less than 5 are an estimate based on extrapolation of the relationship between Methylglyoxal and UMF.<\/p>\n<p>The test method for measuring Methylglyoxal (MGO) concentrations is accredited by IANZ.<\/p>\n<p>Professor Peter Molan already had a strong suspicion about this unique effect, which he called UMF (Unique Manuka Factor), comparing a certain percentage of phenol solution. UMF and NPA are the same modes of testing. He called this 5+, 10+, 15+, 20+ and 25+ and corresponded to the respective phenol percentages of 5%, 10%, 15%, 20% and 25%. This test method turned out to be inaccurate due to the many error margins in the test results. However, he and his team were unable to identify the active connection at the time.<\/p>\n<p><em>*Isolation by HPLC and characterisation of the anti******* active fraction of New Zealand manuka (Leptospermum scoparium) honey.
