As a banana ripens, it gives off ethylene gas. This gas is instrumental in the ripening process. In fact, it is this same gas that is used by banana importers to accelerate banana ripening once the bananas are ready to go to market. By placing bananas in a paper bag, you are concentrating the gas that is emitted from the fruit. As the concentration increases and the ripening process accelerates, more gas is emitted faster. Essentially, you have a chain reaction taking place -- more ripening means more gas, which means more ripening, and so forth.

Do bananas ripen faster in a plastic bag or do they ripen faster when not in a plastic bag?

Bananas ripen quickly on their own as they're one of the few fruits that release ethene. Keeping them together in a plastic bag should make them ripen. Keep them away from other fruit that you don't want to go off, and if you want avocados to ripen put them in a brown paper bag with bananas in an airing cupboard.

Can bananas make other fruit ripen faster?

They can if -the bananas are already ripe, andthe bananas are placed in the immediate vicinity to the other fruit (such as in a fruit bowl)This is because bananas give off ethylene gas which makes fruit ripen faster.Some companies that artificially grow fruit use ethylene gas to ripen their fruit faster (although this gas is concentrated, not from growing bananas with other fruit)
