Manuka honey from liquid gold & # 39; that costs £ 100 per pot, may have lost its healing powers before you get it home, warns the scientist
- The honey has antibacterial properties that come from a chemical that hinders insects
- Chemical material can be destroyed by prolonged exposure to heat when it is shipped
- Professor Merilyn Manley-Harris also said that manuka in the UK could be mislabeled

Expensive manuka honey may have lost its healing powers before customers bring it home, a scientist has warned.
The honey, known as "liquid gold", because it costs up to £ 100 per pot, is sought after due to antibacterial properties that come from its naturally occurring bug-fighting chemical.
But this chemical can be destroyed by prolonged exposure to heat – such as during shipping or even sitting in shop windows – according to Professor Merilyn Manley-Harris.
The honey chemist at Waikato University in New Zealand warned that some manuka honey sold in the UK is wrongly labeled as stronger than is actually the case because it is damaged by heat.

Professor Manley-Harris said that people should buy manuka honey (see above) which is stored in a cool place
Popular with celebrities, manuka honey is made from the nectar of the native New Zealand manuka shrub. The honey contains the chemical methylglyoxal (MGO) which has antibacterial properties. Pots carry a label with the strength of the honey – or how much of this chemical it contains.
But research shows that about half of the sold honey & # 39; manuka & # 39; maybe not real and some contain less than MGO than indicated on the label.
Manuka honey is tested for strength before it leaves New Zealand, but Professor Manley-Harris said: & # 39; It's a minimum of four to six weeks to ship, the containers are not chilled and the inside of a hull can get pretty hot to become.
Once it is in the UK, the way honey is processed in the store can also have an impact. & # 39;
The damage is caused by heat accelerating the speed at which MGO reduces naturally. She added: & # 39; If you buy honey that has been shipped, buy one that has also been tested when it arrives.
& # 39; Do not buy the pot in the window. Buy one that is in the cool. & # 39;
