It is because, the water that is present inside the veins of bananas get expanded when is cooled from 4 deg celsius to 0 deg. at refrigerator. As the expansion of veins reaches climax it can't be holded any more and finally bursts causing blackening of bananas. It is included in the topic ANOMALOUS EXPANSION OF WATER!!!!

Sorry, but while it's true that water does expand slightly as it's cooled from 4C to 0C, it's a very very tiny amount of expansion (about 0.01%). In order for it to expand enough to actually burst veins or cells in fruit, you have to freeze it. –  Jefromi Aug 12 at 16:46
