Bananas are a tropical fruit and have no natural defence against the cold in their cell walls. These become ruptured by cold temperatures, causing the fruits’ digestive enzymes to leak out of the cells, which is what causes the banana’s skin to turn completely black, according to A Moment of Science.
Do bananas go bad in the cold?
Bananas grow in hot climates, so they are unused to the cold. If they’re kept at a cold temperature, the enzymes that enable them to ripen are inhibited. And as those enzymes become inactive, other enzymes operate more efficiently. Some cause cell damage, while others (browning enzymes) cause the skin to blacken.
