Why do bananas spoil quickly at home, but they can last a long time in the supermarket?

There are professional ways to keep bananas fresh in the supermarket, but bananas bought at home do not take any preservation methods. Secondly, the appearance of the supermarket must first be passed, and the broken bananas will not be placed outside.

In the supermarket, there must be good-looking, fresh bananas. One method, very straightforward, is to put the freshly shipped bananas directly. Generally, in large supermarkets or fruit supermarkets, the volume of goods is still relatively objective, and the stall of bananas cannot be sold, and half of them can still be sold.

But if you are unlucky that day and you don't sell many bananas, you want to continue selling them tomorrow, and you want to make sure that the bananas are in good shape. First of all,The environment in which bananas are kept should be relatively low, which can slow down the diffusion of auxin and slow down the ripening of bananas.

In addition, because bananas are grown in the south, if you pick ripe bananas and transport them to the north, they will all rot when they arrive in the bananas, so the bananas that are transported to the north are actually green bananas that are not yet ripe, which is easy to preserve. So,In order to look good, merchants can estimate the amount of the day's receipt, only ripen a part of the bananas and sell them on the same day, and then ripen new ones the next day. For the ripening of bananas, it is actually not very scary, because the ripening of the fruit itself is completed under the action of the ripening agent produced by itself, and the ripening agent used by the merchant is generally harmless to the human body.

Of course, there are many ways to keep bananas fresh in our daily life:

1. Banana is a tropical fruit, so storage below 10 degrees can easily cause its surface to turn black and accelerate deterioration. So,Freshly bought bananas should not be stored in the refrigeratorThis is a mistake that many consumers make.

2. Everyone knows that apples have the effect of ripening other fruits, and alsoNote that apples cannot be placed together with bananas

Wrap the banana in plastic wrap and place it in a well-ventilated place to avoid squeezing or bumping.

Freshly bought bananas from the supermarket, rinse them several times with clean water, then wipe off the surface with paper or rags, wrap them tightly in newspaper, and put them in a ventilated place at home.

In fact, no matter what kind of fruit it is, it is best to eat it while it is fresh, try to eat as much as you want, and if you really buy too much and don't finish it, keeping it fresh is the most important thing.

This one is because it's too hot at home and you don't need to wrap it tightly in that bag at home

This is because bananas have a special preservation method in the supermarket, so they can be stored for a long time.

Supermarkets are places where business is done, and there is a lot of traffic every day. Put out a few bananas every day and wait for them to be sold before **, so as to ensure the freshness of the bananas.

Because bananas are not particularly ripe when they arrive at the supermarket, they can be left for a while.

Because they are stored in the freezer when they are stored in the supermarket.

Because supermarkets usually refrigerate bananas, they can be stored for a long time.

Because the supermarket will coat the banana with something to keep the banana as it is, and someone will buy it.

Because if you put it in the supermarket, others will take care of it, and if you put it at home, it will definitely be easy to break.

Because the supermarket has special preservation skills, and the temperature is relatively constant, the home is too hot.

Method 1: Suspension method.

We usually put the bananas in the bag and put them casually, but if we put them flat like this, the bottom of the banana will be compressed, which will easily make the banana crack, so that it will be black and soft. At this time, we need to hang the banana upright with a rope, so that the banana will not be too oppressed, and the preservation time will naturally be longer.

Method 2: Put a piece with an apple.

We washed the bananas we bought in water and thoroughly wiped them off with kitchen paper. Then put the bananas and apples in a bag, drain the air in it as much as possible, then seal them and put them in a dry and cool place, this method is still very fresh for 10 days.

Method 3: Keep dry.

Many of the bananas sold now have been ripened with a ripening agent, and after we buy it, there is a ripening agent on it, so that the longer we leave it, the easier it will ripen and rot. We need to wash the bananas we bought in water, and then dry them with kitchen paper to keep the surface dry, so that the bananas can not change color for a few days.

There is no way. Put in the refrigerator. This would have been if it had been a ripe banana. It's not easy to save. Because it's easy to rot. So,This is too. There is no way to do things. Bought. Eat him as fast as you can!

Then you can wear the banana with a rope and hang it, so that it can be kept for a longer time, and when you buy bananas, if you can't eat them for a while, you have to buy some yellow and green, so that the bananas will be placed for a longer time.

A good solution is to put it in the refrigerator, but it will still rot when it should be. You eat it in time, and it won't rot. It won't rot in three days.

Won't rot in this case, you wrap it in plastic wrap well, and he will generally reduce its time.

Bananas rot easily, what's the best solution?

The bananas purchased by the family should be kept for a short time to avoid rotting, and they should buy bananas that are not too ripe when buying, so that they can be put for a few more days, and at the same time, they should be eaten in time after the bananas are bought, and should not be placed for too long, resulting in waste.

The best solution is not to buy so much and buy too much, and it will definitely be easy to spoil if you can't finish eating.

No, even if you do, it is not recommended to leave it for a long time, so when you buy it, it is best to buy it on the same day.

It is said that wrapping banana roots in plastic wrap can prolong the storage time of bananas.

Don't put the banana in a plastic bag, wrap it in plastic wrap and turn it upside down or diagonally.

Generally speaking, bananas do rot easily, so it's best not to buy too much.

In fact, bananas are ripe and easy to spoil in the future, so try to buy a little less.

Then you have to put it in the refrigerator to refrigerate, there is really nothing you can do about this.

Because bananas are leapfrog fruits. Leap fruits have a "post-ripening" process. When endogenous ethylene is produced in large quantities, a series of changes will occur inside the fruit because ethylene is an important factor that regulates fruit growth and jujube ripening

Starch is converted into sugar, organic acids are decomposed, fruit acidity decreases, and pectinase activity increases to differentiate pectin and soften the pulp.

A small amount of banana peel blackened can be eaten. It doesn't matter if there are a few spots on the banana peel, this is because the banana is ripe, and the banana at this time has the best and sweetest taste, so you can eat it with confidence.

Banana peels are blackened in large quantities and should not be eaten. If there are many black spots on the banana peel, it means that the banana is overripe, and these black spots will seep into the flesh from the banana peel.

Banana is a common tropical fruit, bananas can not only be eaten, but also have a lot of benefits. Using bananas for beauty can play a role in whitening the skin, often use banana peel to wipe the face or mash bananas into banana puree as **use, can make** more and more white and shiny, if you want a better whitening effect, then you can also add some milk to the fragrant cherry banana**. Bananas can also have a great effect on roughness.

Commonly used banana** to apply to the face, can make ** become tender, and some **chapped problems can also be improved by bananas.

Bananas can also lighten the pigment precipitated in **, so often apply bananas** or commonly use bananas to wipe the places with colored spots, which can have the effect of lightening the pigmentation and making ** white. It can also be used in the case of itching. Commonly used banana peel beauty can protect the health of the bacteria and prevent the disease caused by bacteria.

Bananas are rich in nutrients, and the commonly used banana ** face can supplement sufficient nutrients for the skin, improve the nutritional status of the skin, increase the elasticity and vitality of the skin, and also have a certain antioxidant effect. Bananas can also moisturize**, improve the state of dry and dehydrated skin, and prevent the skin from becoming rough due to dehydration.

The ripening of bananas is divided into these stages, first all green, then green with very little yellow-green, then more green than yellow, more yellow than green, only the fruit stalk and neck green followed by all yellow, yellow with brown spots. At the final stage of banana ripening, the peel turns from bright yellow to dark yellow, and plum blossom spots appear. The plum blossom spot here is actually a disease spot The anthrax fungus that has been latent in the field to invade the banana fruit, when the sugar content increases in the later stage of fruit ripening, it develops rapidly and shows symptoms At this time, the fruit has completed the peak of respiration and reached the full ripeness c The fragrance of the banana fruit reaches the best and most delicious, and the fiber of the peel is also decomposed due to respiration at this time, and the connection between the fruit stalk and the fruit body is very easy to break and become a stalk phenomenon.

As for how to preserve bananas, there are several ways to wrap the rhizome of bananas with plastic wrap. Because the ripening of bananas in addition to the business will spray ethylene to ripen and its rhizome part will automatically emit ethylene, and it is precisely for this reason that the bananas will be black and deteriorated after being stored for less than two days, and wrap them in plastic wrap to effectively prevent the bananas from rituring themselves. Finally, if there is a condition to hang the banana up with a rope to store it to prevent the banana from crushing the ground, if there is no condition, you can put the banana arch side up, so that the landing area becomes smaller, and it can also effectively prevent crushing.

Bananas are very easy to ripen, so they tend to spoil at home. Bananas should be stored separately and not with other fruits.

Because the temperature at home is different, the temperature of the supermarket is constant, and the common method of patting and dismantling the jujube is to hold the handle of the banana tightly with a plastic bag, and then put the banana in reverse, the effect is better, you can try it.

Bananas are a very tasty fruit, but they are difficult to preserve, and the temperature at home will cause the bananas to rot quickly. Banana parsley base can be kept in the refrigerator.

"Waste" always happens when we think we are still rich, and the same is true for the waste of food, human beings at the end of the chain, with a large number of rich, perfect, and bright ingredients to choose from, do not understand the invisible consumption in the entire industrial chain, and the ecological limits that are about to be faced because of these large amounts of waste.

Those foods that do not meet the standards of supermarket purchases, but are perfectly edible: radishes that are too small, irregular-looking tomatoes, crooked oranges, are discarded.

If you pay a little attention to your life, you will find that food waste is everywhere. For example, the most common sliced bread in supermarkets or bakeries, the crust at both ends of the bread is discarded before it hits the shelves. At some conveyor belt belt sushi restaurants that emphasize the original taste and absolute freshness of the ingredients, they will sign up to tell you that every piece of sushi made here will not last more than 300 meters on the turntable, and waiting for them at the end of the turntable is a trash can for swallowing sushi.

For foods that are completely edible, but are simply picky about the shape or size of bananas, they may be thrown away, and these foods that are discarded in the ** chain are called "leftover foods", and they are not those that are spoiled and rotten and difficult to swallow, but those that are intact and fresh. There are usually three leftover foods, farms, a large number of raw materials that are eliminated in the procurement process, usually ingredients that are not good enough in size and shape, or fruits that are not so pleasant in taste; Supermarkets and vegetable markets, those that have been picked and left with expiring food that is no longer full and bright; In the restaurant, the daily loss of ingredients due to excessive meal preparation.

For the leafy vegetables served on the table, pinch the head and remove the tail, leaving only the middle part; The apples in the supermarket are all crystal clear, and the crooked melons and cracked dates have long been kicked out; Many people have only seen jackfruit peeled, but they don't know that the silk and core in the middle can be used to make soup. In fact, there are many leftovers of ingredients in life that can be eaten, and the nutrition may be better than the main ingredients, and the taste of the slag is also very unique.

As long as the flesh is not spoiled, bananas can be eaten with spots and blackening.

There are four main reasons for banana spots and blackening: first, mechanical damage, such as damage caused by bumps during transportation; The second is to encounter mold, if the already injured banana encounters mold, it will mildew and cause rot; The third is to refrigerate and turn black, bananas, as tropical fruits, cannot withstand low temperatures, and if they are put in the refrigerator, they will be frostbitten; Fourth, I haven't eaten it for too long, and it's overcooked.
