TEA-TREE-HONEY
Tea tree honey points to higher antioxidant levels: study
SYDNEY, Nov. 8, 2018 (BSS/Xinhua) – Honey from bees foraging on tea trees
is higher in antioxidants and displays sustained anti-microbial activity
compared to other honeys, helping to shed new light on the insects’ links
with the major food source, according to a latest research.
“We found bees foraging on Melaleuca trees produced a honey that combines
immediate anti-oxidant activity and a significant sustained anti-microbial
activity even in young honey, without having to wait for the honey to
mature,” Southern Cross University researcher David Rudd said on Thursday.
His study found that the tea tree honey combined “strong immediate anti-
oxidant activity significantly higher” than generic honey – or those from
more common floral sources – and revealed how foraging on the plant benefited
the honeybees, said Rudd.
“A diet of Melaleuca trees is slightly different to what bees usually feed
on so we wanted to conduct gut microbe analysis in case there were any
problems for the bees, but we found the slight changes in the gut suggested
the bees could handle tea tree really well and actually gives the bees a
slightly higher immune function, making them more resistant to bacterial
infections and viral infections without affecting the gut metabolic
function,” he said.
The tea trees “actually acted as a probiotic for metabolism, increasing
beneficial immune defensive bacteria while maintaining nectar metabolism
bacteria within the honeybees’ gut.”
The study covered tea tree plantations in the Bungawalbyn Valley region of
Australia’s New South Wales state and during the research trials, the trees
were provided to the honeybees as a diet supplement, with the insects also
allowed to naturally forage throughout old growth plantations, according to
the university.
The findings are expected to help improve the production, handling,
storage and other aspects of honey from bees foraging on tea trees, it said.
