Understanding Manuka Labels - MGO UMF NPA
Understanding the grading systems of Manuka honey can be a bit complex, but it is crucial for recognising the quality and authenticity of the product. Let's explore the most commonly used grading systems: UMF, MGO, and NPA.
UMF – Unique Manuka Factor
The Unique Manuka Factor (UMF) is a quality trademark and grading system that evaluates natural markers found in Manuka honey, including Methylglyoxal (MGO), Leptosperin, and Dihydroxyacetone (DHA). These markers guarantee purity and quality. The UMF rating reflects not only the concentration of these markers but also certifies that the honey is genuine Manuka.
A UMF rating of 10 or higher is deemed beneficial. The higher the UMF number, the greater the concentration of beneficial compounds.
What do the 10+, 15+, and 20+ ratings actually mean? If a honey is labeled 10+, it signifies that the antibacterial strength of the honey is equivalent to a 10% solution of phenol.
MGO – Methylglyoxal
Methylglyoxal (MGO) is a naturally occurring compound in Manuka honey that contributes to its non-peroxide antibacterial activity. This is what makes Manuka honey superior to regular honey. MGO is usually measured in parts per million (ppm), and higher levels indicate stronger antibacterial activity. For instance, a rating of 100 MGO means there are 100 mg of MGO (methylglyoxal) per kilogram of honey.
NPA – Non-Peroxide Activity
Non-Peroxide Activity (NPA) is another crucial factor in Manuka honey. NPA is a measure of the antibacterial power of the honey, independent of the hydrogen peroxide content found in all honey. Similar to UMF, 10+ NPA means that the honey is equivalent to the antibacterial strength of a 10% solution of phenol.
Making Sense of the Grades
Understanding these grades allows you to select the most appropriate Manuka honey based on your needs. For instance, a Manuka honey with a high UMF or MGO rating would be more beneficial for skin and wound care.
At Kiwi Reserve, we believe in transparency and education. Our honey labels clearly indicate the MGO ratings so you can make informed decisions about the honey you purchase. When you choose our honey, you’re not only getting a high-quality product, you’re also contributing to our conservation efforts to protect the native kiwi, other endangered species and reforestation.
Remember, genuine Manuka honey is more than just a sweet treat – it's a natural product with unique properties, and understanding its grading system ensures you get the best of what nature has to offer.
Here is a useful chart for you to be able to translate between the various grading systems.
| Description | MGO | UMF | NPA |
|---|---|---|---|
| Experience the unique taste of Manuka honey | 83+ | 5+ | 5+ |
| This is where you can start seeing good health benefits | 263+ | 10+ | 10+ |
| Great on a teaspoon each day to add in digestive health or for use in skincare | 514+ | 15+ | 15+ |
| This is a premium grade. Great for health, oral and wound care | 829+ | 20+ | 20+ |
Monofloral vs. Multifloral Manuka Honey
In addition to understanding the grading systems, it's also important to know the difference between Monofloral and Multifloral Manuka honey. This differentiation, introduced by the New Zealand government, ensures you know exactly what you're getting.
Monofloral Manuka Honey
Monofloral Manuka honey is derived predominantly from the nectar of the Manuka flower. This honey features a strong, distinct flavor and a creamier, thicker texture than multifloral honey. Generally, monofloral Manuka honey has higher levels of MGO, which translates to a higher UMF and MGO rating.
The criteria for this grade are strict. Any honey aspiring to be labeled as pure (monofloral) Manuka honey must be sent to a laboratory for testing to verify its authenticity.
Multifloral Manuka Honey
Multifloral Manuka honey, on the other hand, is a blend where the nectar is sourced from the Manuka bush and other flower types. Although it's still rich in nutrients, it typically has a lower MGO level and UMF rating compared to its monofloral counterpart. This is why the price of Multifloral Manuka will be cheaper. If the honey is exported from New Zealand, then the honey must be labeled as Multifloral Manuka to signify its lower grade.
Why This Matters
This differentiation is crucial as it ensures the purity and authenticity of the Manuka honey you are purchasing. The New Zealand government requires exported Manuka honey to be labeled as either monofloral or multifloral. This provides a clear indication of the honey's source, allowing you to know exactly what you are buying and consuming.
At Kiwi Reserve, we only sell the best when it comes to honey. You will find that all our Manuka honey is unmixed, raw, and pure monofloral Manuka honey.
