keep it on a plastic bag
Bananas are harvested way before they ripen so they can be delivered without bruising or over ripening. That's way most of the bananas you see at the super market are green.
Put them in a paper bag.
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.
Nancy Millis discovered quite a few things. She found a way to ripen bananas, she worked on the fermentation of cider, and studied the microorganisms of fermentation.

They need to be softened off the tree. Firm avocados take about two to three days to ripen. To speed up the process, place them with ripe apples in a paper bag and loosely close it by scrunching the top of the bag. Apples emit ethylene gas that make fruit ripen quickly. This includes bananas, tomatoes and cantaloupes.Fruits That Become Sweeter After Picking:ApplesCherimoyasKiwisMangosPapayasPearsSapotesSoursopsFruit That Ripens in Every Way After Harvest:Bananas
Putting an unripe tomato in the sunlight is a bad way to ripen them. The best place to put an unripened tomato is on top of your refrigerator. The warmth is what helps them to ripen. Enjoy your tomatoes!
Answer:The best way to keep bananas so they don't ripen too quickly, is to hang them up so they are not touching anything. This is done in many large supermarkets in England.
Commercially, bananas are placed in a room and exposed to ethylene gas in order to accelerate the ripening process. As a consumer, the best way to do this is to place the bananas in a paper or plastic bag and store it in a warm area. Take care to inspect the fruit as it will ripen fast. As a banana ripens, it produces the same ethylene gas mentioned above. By placing the fruit in a bag, you are allowing the gas to concentrate rather than be dispursed as it would if the fruit were stored in the open.
When a banana decomposes it creates ethylene oxide, amylase, and protease gasses. If kept in a bag the gasses can not escape and will cause the fruit to age rapidly. If on the counter it will age more on the bottom first, where the gasses are more isolated. The best way to keep bananas from aging is to hang them over the counter on a fruit stand of some sort. NOTE: If you have unripe fruit, you can set it in a bowl with a bunch of bananas and it will ripen faster.

Not all mangos change color as they ripen, so the best way to tell if mangos are ripe is to squeeze them gently.
