Bananas grow in hot climates, so they are unused to the cold. If they're kept at a cold temperature, the enzymes that enable them to ripen are inhibited. And as those enzymes become inactive, other enzymes operate more efficiently. Some cause cell damage, while others (browning enzymes) cause the skin to blacken.
Putting ripe bananas in the fridge will help them stay ripe for a few days – but if you put them in while they are still a bit green and hard then they won't ripen at all. Not even after you take them out of the fridge. And their skin will turn black.
Placing bananas in the fridge will keep the fruit fresh, but the banana peel may turn brown. The cooler temperature slows the ripening process, and as long as your banana is yellow and fresh when you put it in the fridge, it will be safe to consume after cooling in the fridge for a couple of days.

Stashing your bananas in the refrigerator can slightly prolong the fruit's life—but there's a caveat. When it comes to refrigerating bananas, timing is everything. Refrigerating bananas will slow or stop the ripening process, preserving the fruit at its current state.
Bananas are picked green and ripen at room temperature. Refrigerating them not only causes the skin to darken, it slows down or stops ripening. So, it is best to keep them out of the fridge until they are fully ripened. At that point refrigerating them will help keep them from becoming over ripe.
When they have fully ripened, it's a good idea to store bananas in the fridge to extend their freshness – in a fridge, they will keep nicely for an extra week or two. But be careful – until they do go yellow, putting them in the fridge can prevent them from ripening properly.
Bananas, like many fruits, release ethylene gas naturally, which controls enzymatic browning and ripening of not just itself, but other fruits nearby. Much of that offgassing takes place at the stem—or the crown—of the banana. By wrapping the crown of a bunch, you slow down the ripening process a bit.
Best practice is to store eggs in the fridge; that way the temperature is always at a constant and your eggs will be fresher!
Don't toss those green bananas! You may not believe me, but the truth is they WILL eventually get ripe. If they arrive to your site very green, it likely means they did not get enough of the ethylene gas that speeds the ripening process, but they will ripen naturally. It can take up to 6 weeks.
Bananas are tropical fruits, and, in general, tropical fruits don't handle cold storage well. That's why the best way to store bananas is at room temperature, not in the fridge, especially when they're green and not yet ripened.
Ethylene-producing fruits, such as apples, bananas, peaches and honeydew melons, should not be stored next to avocados, lemons, grapes, onions and other fruits or vegetables that are sensitive to this compound.
Scientists report that cold temperatures suppress the activity of proteins that play a key role in the formation of the banana's distinct aromas. They say this discovery could lead to enhancements of the fruit's fragrance and flavor. Bananas are one of the world's most popular fruits.
Ethylene gas is naturally released through the stems of the bananas. Separating, and especially covering the end of the stems, should contain the release of this gas, thereby slowing the rate of ripening.
Bananas. Surprised? You may be used to keeping your bananas in prime pantry real estate, but if you keep them there, they just keep ripening. When they're ready to eat, put them in the fridge, the Academy of Nutrition and Dietetics says.
Bananas start ripening as soon as they're picked from trees—ethylene gas releases from the stems as soon as they're picked, but when you hang bananas from a hook, the gas works more slowly. Hanging bananas also prevents them from bruising on the counter, which they're more prone to do as they continue ripening.
Keeping bananas in the fridge will slow the ripening process, but they will ripen over time. To keep bananas in the fridge, you need to place them in there when they reach the level of ripeness you like most. But bananas that already have brown spots will not hold up well in the fridge.
They prefer the refrigeration. Apples keep longest when held at 31-36 degrees Fahrenheit. So, you want to keep them in the coolest part of the refrigerator. Most home refrigerators don't get that cold because the rest of your food would freeze, but the colder the better.
If stored correctly, you'll have ripe bananas in 2 to 5 days. If you're curious about how to keep bananas fresh for longer, you should know about how to store bananas in your refrigerator. If you place them in the refrigerator, fully ripe bananas will last 5 to 7 days.
A ripened banana can be popped in the fridge for up to a couple of weeks and even if the peel turns brown or black the flesh will be good to eat.
Dividing your bananas and wrapping them individually is the best way to prevent the ethylene from traveling down the fruit. Plus, when you're ready to eat your bananas, there's no need to unwrap the stems.
Ditch the Plastic Bag
Bananas that are stored in plastic bags will ripen faster. Instead, keep your bananas at room temperature in a cool, dark place to be sure they receive fresh, well-ventilated air. Bananas sitting in direct sunlight or near the stove will shrivel up and turn brown at a faster rate.
