Why do bananas change Colour?

The yellow comes from the diminishing amount of chlorophyll as the banana ripens and turns from green. The banana then turns brown as the sugars ferment within the banana and its peel.Why do bananas turn brown?High amounts of ethylene cause the yellow pigments in bananas to decay into those characteristic brown spots in a process called enzymatic browning. It seems like your grandma was right—a green banana that’s placed in a brown paper bag will ripen faster because of all the ethylene trapped inside.
