What is MGO?

MGO (Methylglyoxal) is a natural organic compound that plays a crucial role in the unique antibacterial properties found in genuine manuka honey. This compound is primarily responsible for the potent medicinal benefits and high therapeutic value that have made manuka honey famous worldwide.

Origin and Formation – Methylglyoxal is a dicarbonyl compound that arises through the breakdown of a sugar called dihydroxyacetone (DHA), which is naturally present in the nectar of manuka flowers (Leptospermum Scoparium). DHA is converted into Methylglyoxal over time as the nectar ripens within the hive and during the honey’s maturation process.

MGO Rating System -The MGO rating system quantifies the concentration of Methylglyoxal in manuka honey, typically expressed in milligrams per kilogram (mg/kg). The higher the MGO rating, the more potent the honey’s antibacterial activity. For instance, MGO 500+ indicates that the honey contains at least 500 mg/kg of Methylglyoxal.

Stability and Storage – Methylglyoxal is a relatively stable compound, allowing manuka honey to maintain its potency for long periods if stored correctly. It is essential to store manuka honey in a cool, dry place away from direct sunlight to preserve its bioactive properties.

Authenticity and Testing – Given the popularity of manuka honey, ensuring its authenticity and MGO content has become crucial. Reputable brands submit their honey for independent laboratory testing to verify the MGO concentration and determine the UMF rating, ensuring consumers receive genuine and high-quality manuka honey. The relationship between UMF and MGO lies in the fact that Methylglyoxal (MGO) is one of the key compounds considered in the Unique Manuka Factor (UMF) rating. Convert your UMF to MGO Here.
