Fera honey analysts use industry leading techniques and cutting edge technologies to establish levels of the marker compound leptosperin within your Manuka honey samples. Through this analysis, the authenticity of your Manuka honey can be assessed against the findings of international research programmes and industry standards.

As a high value product, Manuka honey is regularly adulterated, blended and diluted. Fera offers chemical and microbiological analysis - including the new Leptosperin Manuka specific marker test - to confirm the authenticity of honey labelled as 'Manuka'. All analyses are fully validated and performed to current industry standards. Fera is the Unique Manuka Factor Honey Association (UMF® Honey Association) key science partner in the UK, acting as an official testing laboratory for independently verifying the UMF® rating of Manuka honey.

Leptosperin is a naturally occurring chemical, found only in the nectar of Manuka plants (and a few very close relatives) and can therefore be used to confirm the authenticity of honey labelled as 'Manuka'. It was first identified (and patented) by Japanese researcher Kato in 2014. Leptosperin concentration is stable over time, and therefore measuring its concentration in honey is an ideal way of identifying whether the honey comes from Manuka flower nectar, and whether it can be labelled as Manuka, a Manuka blend, or as a multi-floral honey.

Manuka Honey: Microbiological Testing

Total Activity (TA) and Non-Peroxide Activity (NPA) are measures of the ability of a honey to inhibit microbial growth. Phenol equivalence testing through traditional plate bioassay methods is used to accurately assess these levels and allow producers to ensure labelling requirements are met.

Diastase Test

Can you be confident that your storage facilities aren’t degrading the quality of your products? Fera Science can perform analysis on honey samples for diastase enzyme activity (diastase number) giving you the confidence in the quality of your product. using the official Phadebas® assay for determination of diastase activity.
