Manuka Honey - Nature's Wonderfood

For thousands of years honey has been recognised as having beneficial health-supporting qualities due largely to an enzyme activity.

It has also been recognised that certain honeys from specific plants are more effective than others, and the honey that comes from some strains of the New Zealand Manuka bush (Leptospermum Scoparium) is one of these.

 The New Zealand Honey Discovery

In 1981 research at the Honey Research Unit at New Zealand's University of Waikato discovered that some strains of manuka honey have an extraordinary, naturally present, very stable property not found in any other variety of honey.

This special property is over and above the usual properties of honey.  It comes from the nectar of the manuka flower  and is quite distinct from the enzyme activity that is common to most honeys.

This special property sets Manuka Honey apart as one of nature's true wonderfoods.

But this special property is not in all manuka honey.

Helping Consumers Identify Manuka Honey that has the Special Property

Until recently consumers had no way of knowing the level of quality or authenticity of the Manuka Honey they were buying. Depending on the season and source, honeys can vary in grade and strength. So it has been important to establish a trusted quality standard.

The UMF Honey Association has achieved this by introducing the UMF quality trademark and rating system.

The official UMF logo helps consumers identify genuine UMF Manuka Honey

Testing for Authenticity - Protecting Your Rights as a Consumer

To determine if the special property is present in manuka honey each batch must be tested (after packing) in specifically approved laboratories using stringent criteria laid down by the UMF Honey Association.

The UMF Honey Association testing utilises a range of internationally recognised biological and chemical methods in approved laboratories both in New Zealand and internationally.

As part of the testing process every batch of honey must also go through a series of additional checks and supporting programmes to ensure the ultimate in authenticity, quality and safety.

All UMF licence holders are independently audited to meet stringent standards in terms of production, manufacturing, sampling and handling.

The UMF designation and rating is a highly sought-after and well-respected quality trademark.

Why is UMF In Only Some Manuka Honey?

Bees gather manuka honey from the nectar of the flowers of the manuka bush (Leptospermum scoparium) which is a native plant of New Zealand.

The manuka bush grows wild on undeveloped, unspoilt and regenerating land, and is commonly found throughout the country. 

Manuka honey with the special property is gathered from the manuka flowers in only a few places in New Zealand.

It is also evident that some areas of manuka bushes do not produce honey with the special property every year, and the concentrations of the manuka property can vary from batch to batch and year to year.

For this reason samples of every batch of UMF Manuka Honey are tested before and after the honey has been packed into jars. 

The special property comes from the nectar of the flower; whereas the enzyme activity common to most honey is due to an enzyme added to the honey by the bee.

The reason why only some manuka honey has the unique property is not yet known.   It could be from a sub-species of manuka or due to some environmental factor such as soil type. The researchers are currently looking into this question.
