The honey industry is estimated to have exported around 8,600 tonnes of honey in 2009, generating revenue in excess of NZ$100M, of which Manuka honey alone accounted for around NZ$70M of that revenue. However poor knowledge surrounding the effects of excess sugar feeding on honey quality can render a high value product to one which is virtually unsaleable. Furthermore, a basic but crucial sugar test is applied internationally as the main generic C4 cane sugar adulteration test to fulfil export acceptance. This test is now gaining traction in the honey industry as a quality check of New Zealand honey, both for the local and export market. Failure means that these market opportunities are being lost, reputations damaged and brands tarnished.
