At Minerva we have developed unique expertise in the field of honey antimicrobial activity testing and the analysis of New Zealand Manuka honey.

Honey Activity Testing

Anti-microbial Activity Testing
Honey has natural anti-microbial properties due predominantly to the natural presence of peroxide in the honey. Certain speciality honeys may have additional anti-microbial activity from other natural constituents of that particular honey type. The most widely publicised of such honeys is New Zealand Manuka that is often marketed with a Unique Manuka Factor (UMF) indicating the ‘activity rating’ of the product. This rating is determined by microbiological bioassay and is expressed in terms of equivalent inhibition by phenol standard solutions. We are able to offer bioassays capable of determining both Total Activity and Non-Peroxide Activity in honey. Activity range 8 to 20+ % w/v phenol is normally offered, although we can offer additional assays capable of determining lower activities ranging from 4 to 8 % w/v phenol.

Anti-microbial Activity Testing
  • Microbiological Total Activity Assay (% Phenol)
  • Microbiological Non-Peroxide Activity Assay (% Phenol)

Methyl Glyoxal (MGO) Analysis
It has been widely publicised that methyl glyoxal (MGO) is the major constituent of manuka honey responsible for its non-peroxide anti-bacterial properties. More recently, it has been determined that dihydroxyacetone (DHA) is the precursor of MGO in the nectar of manuka flowers. We are able to offer quantitative HPLC analysis of MGO and or DHA in honey. This determination can be used to confirm activity assay findings, or as a more rapid method for the determination of non-peroxide activity.

  • Methyl Glyoxal (MGO) by HPLC
  • Methyl Glyoxal (MGO) and dihydroxyacetone (DHA) by HPLC

Manuka Honey Authentication
We can offer a range of tests suitable for the verification of manuka honey identity. Manuka has a very characteristic viscosity profile that sets it aside from most other honey types. Coupled with pollen analysis (by microscopy), this package offers a comprehensive assessment of Manuka-like characteristics.
