Leptosperin is a naturally occurring chemical found only in the nectar of Mānuka plants.  It stays stable over time, which makes testing for Leptosperin in honey a good way of identifying if it contains Mānuka , and if it is concentrated enough to be labelled as Mānuka Honey.

It was identified first (and patented) by Japanese researcher Kato in 2014. Later that year its presence in Manuka nectar was reported by the UMFHA and Analytica Laboratories at the Apiculture (Beekeeping) Industry Conference in Whanganui, New Zealand.

Leptosperin is the first of what could be a number of Manuka specific chemical markers used to identify Manuka honey for authenticity and labelling purposes.

This is a huge step toward eliminating adulteration and counterfeiting in the Mānuka Honey industry. Ka Noa are very excited to see how this testing will progress and affect our industry.
