That banana sitting on your kitchen counter with a few brown spots might look like it's past its prime. But those spots are actually one of the visible signs of ripening.
As a banana ripens, several natural changes take place inside the fruit.
When bananas are harvested, they contain more starch and are relatively firm. As they continue to ripen, enzymes gradually break down those starches and convert them into simpler sugars. This is why a ripe banana tastes noticeably sweeter than a green one.
At the same time, the peel undergoes its own transformation. The green colour comes from chlorophyll. As the banana ripens, chlorophyll breaks down, revealing the yellow colour underneath. With further ripening, the peel develops small brown spots as the cells and pigments in the skin continue to change.
That's why brown spots don't automatically mean the banana has gone bad.
In fact, a spotted banana is often softer, sweeter and more intensely flavoured than a greener one.
Of course, there's a difference between natural ripening and spoilage. If the banana has an unpleasant smell, leaking liquid, extensive mould or an unusual texture, it's best not to eat it.
So next time you see those little brown spots, remember:
They're not just marks on the peel. They're signs of a banana becoming what it was meant to be.
