Washington, October 21: A team of Austrian and American researches has discovered that ripening bananas appear bright blue under black light.

Scientists at the University of Innsbruck and Columbia University say that the blue glow is connected to the degradation of chlorophyll that occurs during ripening.

Lead researcher Bernhard Krautler says that, in this process, colourless but fluorescing breakdown products of chlorophyll are concentrated in the banana peel.

The usual appearance of bananas is mainly the result of the natural pigments carotenoids, which appear yellow under normal light.

However, when exposed to UV light, known to partygoers as black light, ripening bananas appear blue instead.
