How do you make banana's last?

Answer 1

Keep them in a place with good ventilation. This removes the airborne chemicals that ripe bananas give off; these make bananas around them ripen further so getting rid of them will make your bananas ripen slower. Chill them; this makes them very inactive in terms of ripening and is a standard way of keeping something fresh longer. If you have many bunches of bananas, keep the riper ones separate from the less ripe ones, for the first reason above; you can then apply the above on the different groups of bananas you have.
