How does a banana get more sugary after it over-ripens, even after it is cut off of its tree?
In: Biology
It can ripen after being cut off if a fruit first grows to size with starch, and then starch gets broken down into sugar as it ripens. It already contains all the carbohydrates, it’s just more like a potato than a sweet fruit.
Not all fruit work this way though, pomegranates and citruses won’t get any sweeter after they’re picked.
