Why bananas ripen so quickly, and the trick that may slow it down

Bananas are among the most adored fruits across the globe in the kitchen However, they have an issue that is frustrating. On one day, they're perfectly soft and yellow, but after a short time they become to brown, soft, and insipid. In the event that you've felt that you're running against time to complete a batch of food items, then you're not the only one. However, recently it's been discovered that a simple technique has gained attention due to its capacity to slow the speed of this process. And it involves something invisibly within the air.

What is the science behind why bananas are quick-ripening?

The answer to the mechanism behind this is the ethylene gas. It is a natural chemical that is released by fruits as they mature. The banana is a major producer of the gas the majority of which goes via the stem. When it is released, ethylene does not just alter the particular banana it was released from. It also circulates through the atmosphere, which causes the nearby bananas, as well as various other vegetables and fruits to mature more rapidly.


This phenomenon has been extensively investigated, including in the "Postharvest Ripening Behavior of Climacteric Fruits" study carried out at the University of California, Davis in the United States. Researchers discovered that regulating exposure to ethylene was among the best methods to slow down the ripening process on fruits, such as bananas.

How do you wrap the stem to work?

That's how the technique of aluminum foil can help. When you wrap the banana's stem bunch of foil, you are able to limit the quantity of ethylene gas that is released into the air surrounding it. Since there is less gas in circulation in the process, ripening is slowed down significantly. They still mature, however, at a slower speed, which gives you additional days to wait until they are overripe.

In the event that aluminum foil isn't in stock or not available, then plastic wrap may perform the same function. It is designed to provide a shield surrounding the stem and thereby reducing the expansion of the ethylene. This is a minor change, yet it could make significant difference in the length of time your bananas remain in good condition.

Bananas that are hung to avoid bruises

Another less-known element that speeds the process of ripening is physical injury. If bananas are placed on the surface of a countertop that is hard or table, they could develop tiny bruises that develop over the course of time. This can release more ethylene and speed up the process of turning brown.

Hanging bananas on a hanger can solve the problem. If you suspend them from an apron or hanger, it is similar to how they develop naturally in a tree. This helps reduce stress on the fruits and reduces the risk of bruising. This can slow down the ripening process. If combined with foil wrapping technique, this could significantly increase the longevity of the bananas you buy.

Beware of untrue neighbors

Storage space also is a key factor. The banana should not be stored in close proximity to other ethylene-producing fruit like apples as they could trigger each other's ripening more quickly. Similar to that, vegetables sensitive to ethylene such as carrots or leafy greens could wilt earlier in the event of storage near.

The best option is to set bananas next to things that are neutral, such as dry goods, or roots vegetables like potatoes. This straightforward separation can help maintain the freshness of bananas, not only for them however, for all other fruits and vegetables also.

Thermo, light and the most common errors

Most people realize that exposure to light speeds up the process of ripening bananas and ripening bananas, therefore keeping them within a cool and shaded space is crucial. One common error is to put bananas in a plastic bag to keep out the light. Although it might seem beneficial however, it holds ethylene gas, which accelerates the process of ripening instead of reducing it.

The subject of refrigeration is also a thorny one. Though it could be the best way to store the fruit, temperatures that are cold can result in the peel becoming darker and also cause the fruit to fall much more easily. Insides may be edible, however the texture and look often are affected.

The bananas have reached the point of ripeness to be saved

Even with the most efficient ways to store them, they will soon reach the point at which they're too old to consume fresh. However, that does not mean that they must end up in the trash. It's a great option to freeze them for a variety of reasons, particularly if you remove them and keep them in a sealed container so that you don't get the risk of burning in the freezer.

The overripe bananas can also be used to use in recipes. Banana bread has been a long-standing favourite, and smoothies are an efficient and nutritious option. If you want to be more imaginative fruit, bananas mashed can be spread on the tray, then topped with peanut butter and chocolate as well as frozen into the delicious treat known as banana bark.

An easy trick with an impactful effect

The thing that can make the trick with aluminum foil attractive is the simplicity. The technique doesn't require specific tools or complex processes, only an knowledge of how bananas work with the air they breathe. Through reducing ethylene gas and decreasing physical damage you will be able to enjoy the fruits more long and consume less food as well.

Sometimes, the most efficient methods are those that are simple for this situation. In this instance just a tiny piece of foil can create a huge change.
