The colourful melt-in-your-mouth cotton candy sold on the streets of Mysuru has turned white, following the Karnataka Government’s ban on harmful colours used in gobi manchurian and cotton candy. The ban was imposed over health concerns, primarily because eateries use food colouring agents like Rhodamine-B and Carmoisine, which studies have shown to be toxic. While children were disappointed to see vibrant hues of pink and blue fade off their favourite confection, health officials said they were hoping to see fewer colours on other snacks including gobi manchurian.
