what causes bananas to rot
All fruits, bananas included, give off CO2 which helps in the decomposing factor. Since your refrigerator is closed and only has so much space the CO2 builds up and causes theâ¦m to rot. . Bananas do not rot faster in a refrigerator. In fact, they will last longer there. The skin turns brown or black faster in a refrigerator, but the banana meat itself does not ripen that much more. In fact, it is recommended that ripened bananas be frozen to preserve them even longer.
