Why do bananas spoil more slowly when they are hung?

The epidermal cells of bananas contain an oxidative enzyme. Normally, they are tightly wrapped by the cell membrane and are not in contact with the air. However, once they are bruised or frozen, the cell membrane ruptures and the oxidative enzyme flows out. It reacts with oxygen in the air to form a black compound, which is the ugly black spot that everyone often sees.

When the banana lies flat, the entire weight is on the contact surface. As the pressure increases, it is likely that some of the cell membranes of the epidermal cells at this contact surface will be crushed, causing the oxidative enzymes inside to flow out, causing oxidation reactions and producing dark spots. When the bananas are hung in a suspended state, they are not easily damaged because they do not touch any surface, and the air circulates, so they can be stored longer.

Banana is called the "fruit of wisdom" because it is rich in potassium, which is needed for brain function. Friends who are losing weight and have a sweet tooth all like bananas very much. The reason why they have such an extreme audience is that bananas themselves are a nutritious food.

For people who want to lose weight, bananas have a satiety effect, provide natural sugar, and can be mixed with various fruits and vegetables. For people with a sweet tooth, the natural sugar in bananas makes them safer to eat than any other fruit. Even if they are not yet ripe, you can still taste a little sweetness from the banana pulp.

But bananas have a fatal flaw, that is, their storage time is extremely short. Friends who have bought bananas know that if you want to store bananas for a longer period of time, you must buy unripe bananas that have not yet turned green to yellow. However, unripe bananas are not sweet enough in texture and taste, and taste astringent. I bought ripe bananas that had turned yellow, but soon black spots appeared on the outer skin of the bananas, attracting small bugs, forcing me to eat two or three bananas a day.

Is there any way to preserve ripe bananas so that yellow bananas can slow down the time they turn black? The answer is yes. In recent years, many people have said that as long as they buy fresh and ripe bananas and hang them up when they go home, the shelf life of the bananas will be extended no matter where they are hung. When talking about the principle, people say that it is because bananas think they are still growing on the tree, so they are more energetic.
