Dr Yasmina Sultanbawa research into the therapeutic properties of honey

Food scientists at The University of Queensland have discovered a new, low-cost way of accurately predicting the antimicrobial properties of honey.

The new technique could provide a cheaper, more accurate and more practical method of determining the therapeutic properties in honey, benefiting beekeepers, processors and consumers.

UQ Queensland Alliance for Agriculture and Food Innovation (QAAFI) researcher Dr Yasmina Sultanbawa said natural compounds in honeys were known to inhibit Staphylococcus and other bacterial infections such as E.coli. 

Honeys derived from a family of Australian and New Zealand plants were of particular interest to scientists.

 “When a bee sources nectar from flowering Leptospermum plants, such as jelly bush or manuka, the resulting honey often contains compounds that inhibit microbes, the minute organisms that can cause infection and disease,” Dr Sultanbawa said.

“Scientists have developed ways to measure some of these properties, mainly in manuka-style honeys, but these have tended to be limited in scope, requiring relatively complex and expensive testing procedures.

“Both consumers and the honey industry want an accurate but inexpensive way of measuring and classifying the range of therapeutic properties in honeys.

“Currently there is no simple method recognised across the honey industry that is accepted as the ‘standard’ for assessment of honey’s medicinal properties and resulting commercial value,” she said.

Researchers tested a range of honey samples for antimicrobial activity and found different levels of antimicrobial properties. For more about this research see the QAAFI site.
