Bananas are known to become brown quickly, usually within an hour, as they oxidize in the presence of air. An enzyme in bananas, polyphenol oxidase, causes a reaction when exposed to air. People often want to save part of an opened banana to eat later, so they wrap the banana to slow down the process of oxidation.
When you bring your bananas home they are already on their way to becoming brown and by wrapping the stems in tin foil or plastic wrap, it will help slow the process down (unless if you're trying to make some banana bread I'm sure you're trying to get them brown a little faster).
Another fun fact about storing bananas: If you wrap the stems with plastic wrap and aluminum foil once they've started to ripen, this is supposed to help them last longer and not turn as fast.
Use Plastic Wrap On The Stems
When bananas ripen, their stems release ethylene gas, and when it spreads to the rest of the fruit, it will quickly ripen and then cause the fruit to rot. The plastic wrap around the stem keeps the ethylene gas contained so the bananas stay safe.
This is known as enzymatic browning. Keep cut fruits, such as apples, pears, bananas, and peaches from turning brown by: Coating them with an acidic juice such as lemon, orange, or pineapple juice. Use a commercial anti-darkening preparation with fruits, such as Fruit-Fresh®*, and follow the manufacturer's directions.
Thus, foil wrap is a better way to preserve bananas than cling wrap. Potential errors and shortcomings of our process could have affected the results of our experiment. Although the sizes of the cling wrap and foil were roughly equal, cling wrap was stretchier and could be wrapped around the banana multiple times.
Banana hats are more than cute – they're functional. When placed over the crown of the banana, the silicone cap under the hat slows the absorption of ethylene gas, keeping them from browning on you too early.
Putting ethylene-producing fruits in an enclosed space helps to concentrate the ethylene and speed up ripening. One well-known strategy is to put bananas or avocadoes inside a paper bag to ripen faster. It's generally not recommended to store bananas in an ordinary plastic bag, as this traps moisture.
Bagging consists in placing a cover over the bunch to protect the fruit against damage caused by insects and other animals, by rubbing against the leaves or by the application of chemical products1 2 . The innovation is attributed to Carlos Gonzales Fajardo in 1956 in Guatemala.
You can take advantage of ethylene's ripening properties at home by putting your banana into a closed paper bag; the paper will trap ethylene while letting in enough oxygen to help move the process along. For even faster ripening, add an apple, pear, apricot, or avocado — they also release ethylene.
Bananas start ripening as soon as they're picked from trees because ethylene gas releases from the stems. But you can wrap those stems with plastic wrap or aluminum foil to slow down the ripening process.
The bottom layer will separate or the peel with apparent ease and fall apart into sections to the ground. If you happen to have the skill to work any tricks, then concentrate on the peel, and perhaps the inside will spontaneously do the same.
Loaded with magnesium and other heart-healthy nutrients, bananas are among the best anti-aging fruits. They hydrate the cells, which have a firming effect on them, and ultimately on your skin too.
We typically compost or throw away banana peels and don't consider them edible. But new research shows they're actually a source of antioxidants and vitamins. The research team tried various batches until they found "the one", which was both nutritious and tasty.
To keep bananas fresh for longer, wrap the stems in cling film to stop the ethylene gas from getting to the rest of the fruit and ripening it too quickly. To make them last the longest – split the bunch into single bananas and wrap each stem individually.

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.
1. Hang your bananas. Turns out there's a scientific reason you should be hanging your bananas from a hook. 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.
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.
