The fruit known to ripen after being picked is the banana. Bananas are classified as climacteric fruits, which means they continue to ripen after being harvested due to ethylene gas production. When bananas are picked, they are usually in a green state, and as they ripen, they transition in color from green to yellow. This process alters the fruit’s flavor, texture, and sweetness. Ripening affects the starches in the fruit, converting them into simple sugars, making the banana sweeter and softer. This characteristic is beneficial as it allows bananas to be harvested and transported before fully ripening without sacrificing quality.
