Why are bananas not purple?

Bananas are yellow because they contain a pigment called carotenoid. Carotenoids are yellow, orange, and red pigments that are found in many plants, including carrots, tomatoes, and pumpkins. Bananas also contain chlorophyll, which is a green pigment that is found in all plants. However, the chlorophyll in bananas is masked by the carotenoids, so the bananas appear yellow.

There are some varieties of bananas that are purple. These bananas are called red bananas or purple bananas. Red bananas contain a higher concentration of carotenoids than yellow bananas, and they also contain a pigment called anthocyanin. Anthocyanins are red, blue, and purple pigments that are found in many plants, including blueberries, raspberries, and grapes. The anthocyanins in red bananas give them their purple color.

So, the answer to the question "Why are bananas not purple?" is that most bananas do not contain enough anthocyanins to appear purple. However, there are some varieties of bananas that are purple, and these bananas are called red bananas or purple bananas.
