Bananas glow phosphorescent blue under ultraviolet (UV) light, Although it may seem quite surprising at first glance, Science, of course, bases this on a logical basis.

This glow, which emits blue light under UV light, is found in banana peels and certain compounds that change during the ripening process thanks.

Bananas undergo many chemical changes during the ripening process.

As bananas ripen, chlorophyll (the green pigment found in plants and vital for photosynthesis) gradually breaks down. In this process of fragmentation various byproducts of chlorophyll is being formed.

These compounds emit distinct blue light when exposed to UV light, which is what makes bananas causing it to glow brightly in a phosphorescent blue color.

From here we can understand the maturity level of bananas.

As bananas ripen, the breakdown of chlorophyll increases, resulting in a more intense blue glow. In addition, the reaction of these byproducts to UV light, Difference between ripe bananas and unripe bananas That is also evident.

In short, this interesting event both the biochemical structure of bananas and the ripening process We can say that it occupies an important place in our understanding.
