Note: Bananas emit a molecule known as ethylene. This gas or compound helps in processing the sugars within the fruit, allowing the banana to soften and change color.
How to Ripen Bananas
1. Use a paper bag
Paper bag creates an incubator effect around the banana, trapping the gases it usually lets off as it ripens, thereby speeding up the process. Basically, you have to produce ethylene gas naturally to ripen it; which is why you will need to add other fruits to the paper bag. The other fruits that release this gas are apples, pears, avocados, kiwi or apricots. Make sure these fruits are already ripe, so they release more of this gas.(Also Read - Apple Fruit Benefits: 8 Incredible Health Benefits of Apple That You May Not Have Known)
2. Put the banana in the oven
Place the raw bananas on a lined baking sheet in the oven and heat them for about 15 to 30 minutes till they turn black. Make sure the temperature isn't too high. Do not put more than three bananas in one go, as you will need the warm air to circulate freely. Once the banana peels turn black, you will know they have softened and become ripened. Let them cool before peeling them off.
3. Use warm places
If you don't want to use an oven, use other warm sources like the top of the refrigerator, which is generally heated. This will help ripen bananas quickly; however, keep checking the fruits every once in a while.4. Keep them together
Get a bunch of bananas and let them stay and ripen together and wrap them in a foil. This way, they will ripen in about 24 hours if not quickly. Basically, more consolidation means more ethylene emitted in one area.(Also Read - 6 Red Banana Health Benefits You Wouldn't Know About)
