(FASTNEWS|COLOMBO) – Australian Health Authorities say they have solved a mystery that prompted much speculation earlier this month.
It began when a Brisbane woman, Neti Moffitt, asked for an investigation into why an orange – partially eaten by her son – had later changed colour.
Scientists have now revealed it was due to a natural reaction between the fruit and a sharpened knife. The orange did not pose a health risk, they added.
Stewart Carswell, Queensland Health’s Chief Chemist, said numerous tests were conducted to determine the cause of the colour change.
The results revealed that anthocyanins – a naturally occurring antioxidant in oranges – had reacted with iron particles from the newly sharpened blade, he said.
