What is MGO in Manuka honey?
MGO was long sought after in the science world. It stands for Methylglyoxal which is a naturally occurring compound in Mānuka honey.
But not all Mānuka honey is the same, MGO levels can vary greatly per batch and therefore we send our samples to independent laboratories to test for the amount of Methylglyoxal in milligrams per kilogram present in your honey.Why is there MGO in Manuka honey?
In 2009, scientists at the University of Waikato (Christopher Adams, Merilyn Manley-Harris and Peter Molan) published research that showed that the methylglyoxal in New Zealand Manuka honey originates from the chemical compound dihydroxyacetone (DHA), which is present in the nectar of manuka flowers to varying degrees.
This research found that “nectar washed from Manuka flowers contained high levels of dihydroxyacetone and no detectable methylglyoxal.” Furthermore, “Manuka honey, which was freshly produced by bees, contained low levels of methylglyoxal and high levels of dihydroxyacetone. Storage of these honeys at 37 degrees Celcius led to a decrease in the dihydroxyacetone content and a related increase in methylglyoxal.”
Which shows the relationship and significance of the conversion of DHA to MGO.Can DHA be found in other honey varieties?
DHA is unique to Manuka nectar, and has not been found in any other floral types of honey. The conversion of DHA to MG occurs slowly over time, and there are almost certainly other compounds in honey that affect this conversion. This is the subject
of a lot of recent and current research. The conversion of DHA to MG is not a 1:1 reaction and current research will help us to better understand this conversion in the future. When we matured the most potent Manuka honey in the world our CEO already saw the potential of the DHA ratio that would later convert into a honey with a potency of MGO 1717+.Read more about the most potent Manuka honey in the world, our Limited Reserve 21.
How do you know the MGO potency of honey?
Measuring the DHA in freshly harvested honey tells the beekeeper about the potential that honey has to develop MG (and therefore NPA/UMF®) in the future. Honey with a higher starting DHA concentration has the potential to have higher MG concentration after storage than a honey with a lower starting DHA concentration.
Zealandia Honey works only with selected beekeepers and sends samples to independently accredited laboratories throughout New Zealand to test the potency of our Manuka honey at multiple stages in the supply chain.How can I verify my product is real?
Zealandia Honey has a well established track and trace system which will indicate the location your honey was harvested. Only true batch numbers and QR codes that we generate are recognised by the system and consumers can verify the date of manufacture, origin of the product and if the batch number matches type of honey they have purchased.
