what is dihydroxyacetone found in
The significance of DHA, MGO, HMF and Leptosperin in Manuka. Methylglyoxyl (MGO) is found predominantly in Manuka honey and is the main chemical responsible for the unique non-peroxide antibacterial activity of the honey. Dihydroxyacetone (DHA), a precursor chemical of MGO, is found in the nectar of Leptospermum scoparium (Manuka) in New Zealand. The DHA levels are often still relatively high in freshly harvested honey. Over a period of time, the DHA will convert to MGO in the honey, through a natural chemical process.
