Why should bananas be soaked in water?

There are several reasons why bananas should be soaked in water:

1.Soaking bananas are easier to preserve and do not spoil easily.

2.Soaking bananas are easier to transport and less susceptible to damage during transportation.

3.Soaking bananas are more convenient to store and can reduce storage time.

In short, soaking bananas in water is to improve their quality and storage time.

Because when harvesting bananas, bananas are not very ripe, they are harvested, and the merchant will use a ripening agent to soak it, and the bananas will slowly become ripe in the middle of transportation.

Soak the banana in water, it is very useful, and I don't know if I eat it for decades, so I quickly tell my family.

How to pick a banana?

Point 1: Look at the color.

Generally, good bananas give people a more shiny and golden luster. Some bananas have a cyan color on the outside, which does not affect the quality of the banana. Ripening is a process, and a little turquoise is fine.

Point 2: Look at the appearance.

When we buy bananas, we should compare its appearance, if the bunch of bananas on the right and the middle of the ** obviously has a lot of scars, and there are more black spots, this banana is already very ripe, we try not to pick such bananas when buying, because it may be overripe and spoiled.

Point 3: Look at the feel.

When buying bananas, we can feel the softness and hardness of bananas, we don't choose bananas that are too hard, those that are too hard may not be fully ripe, and don't pick those that are too soft, those that are too soft may have been a little rotten, we should choose bananas that are moderately soft and hard.

Point 4: Look at the banana stalk.

Pay attention to it, if you see a banana ready to fall off at the position of the banana stalk, such a banana has been ripe for too long, and we should not buy it.

How to preserve bananas?

If you can't eat the banana you bought at one time, you have to store it for a week, we must rinse it with water, because after the banana is picked, it will be sprayed with a ripening agent, if I don't clean the ripening agent, the banana will be ripe and rotten, after cleaning, we must wipe the water on the banana dry, wrap the banana stalk with tin foil, and then put the banana in a ventilated place, which can effectively extend the freshness time of the banana.

Here's how to cook a boiled banana:

Ingredients: 1 banana, 2 eggs, 1 corn.

1. Wash the banana with the skin and set aside.

2. Wash the corn peel and set aside.

3. Wash the skin of the eggs and set aside.

4. Put an appropriate amount of cold water in the pot, put in the prepared bananas, corn and eggs, and the water should be just submerged with the ingredients.

5. After the water is boiled, continue to cook for about 6 minutes.

6. Remove the boiled banana, let it cool, peel it and eat it.

About 5 minutes.

Bananas are high-calorie fruits, and in some tropical regions, bananas are also used as a staple food. Banana pulp is highly nutritious, in addition, it also contains a variety of trace elements and vitamins. Among them, vitamin A can promote growth, enhance resistance to diseases, and is necessary to maintain normal fertility and vision; Thiamine can resist beriberi, promote appetite, aid digestion, and protect the nervous system.

Riboflavin promotes normal growth and development in the body. In addition to stabilizing serotonin and melatonin, bananas also contain magnesium that can relax muscles.

Suitable for. Bananas prolong life, suitable for all ages, and are the first choice for the best. It is suitable for fever, dry mouth and polydipsia, laryngeal cancer, dry stool, hemorrhoids, anal fissure, blood in the stool, cancer patients and after radiotherapy and chemotherapy; It is suitable for people with upper gastrointestinal ulcers, tuberculosis and intractable dry cough.

It is suitable for those who drink too much alcohol and the alcohol is not solved; Suitable for people with high blood pressure, coronary heart disease, and arteriosclerosis; At the same time, it has a good effect on symptoms such as constipation and indigestion; It is suitable for people with steatorrhoea and toxic dyspepsia.

It is a preservative of water.

Food preservatives refer to food additives used in food to prevent deterioration caused by microbial reproduction in the process of storage and circulation, or due to poor storage and sales conditions, the internal quality of food deteriorates, and the color decreases, and is used in food to improve the shelf life and prolong the edible value.

For a long time, food preservatives have a lingering shadow in people's hearts, that is, all preservatives are not good for human health, this view is completely wrong, and now there should be a correct evaluation, and enough attention should be given.

Sodium diacetate is a high-efficiency antiseptic and antifungal agent for food and feed, which can be used for food preservation and preservation, and can also be used for the storage of feed to prevent mildew and improve the nutritional value of feed.

OK. Bananas should not be eaten with the following foods:

1. Bananas and taro are compatible. Eating together can make your stomach upset and feel bloated.

2. Bananas and sweet potatoes cannot be eaten together. Eating together can cause adverse biochemical reactions and cause physical discomfort.

3. Potatoes and bananas should not be eaten together. Eating the same food can cause adverse biochemical reactions, resulting in facial spots.

4. Kefirt and banana are compatible. Eating the same food can cause adverse biochemical reactions and produce carcinogens.

Bananas cannot be eaten with the following foods, so the two can be eaten together.

1. Bananas and taro are compatible. Eating together can make your stomach upset and feel bloated.

2. Bananas and sweet potatoes cannot be eaten together. Eating together can cause adverse biochemical reactions and cause physical discomfort.

3. Potatoes and bananas should not be eaten together. Eating the same food can cause adverse biochemical reactions, resulting in facial spots.

4. Kefirt and banana are compatible. Eating the same food can cause adverse biochemical reactions and produce carcinogens.

Something that cannot be eaten with a banana (there is no boiling water in it, so you can drink it together):

1. Beef. It is said that autumn should be tonic, you must know that beef is not only delicious, but also rich in a lot of nutrients, which is actually the only ingredient for autumn nourishment. Beef is high in protein and low in fat, so it is delicious and loved, and enjoys the reputation of "the pride of meat". But if you eat beef, don't eat bananas, you will have stomach cramps.

2. Taro. Taro is rich in protein, calcium, phosphorus, iron, potassium, magnesium, sodium, carotene, niacin, vitamin C, B vitamins, saponins and other components, and contains a high content of fluorine among the minerals, which has the effect of cleaning teeth and preventing caries and protecting teeth. Taro has high nutritional value, but avoid eating it with bananas, which will cause bloating and poisoning.

I guess it's okay, will there be a chemical reaction between these two?

Bananas are washed with water after picking to clean the juice that flows out of the banana when it is unloaded. Water with preservatives is used to prevent bananas from ripen and rot during transportation.

Bananas are both a delicious fruit and a food. Bananas contain up to 20% sugar. Among them, the ratio of fructose to glucose is 1 1, which is an ideal food to supplement sugar and eliminate fatigue, so it is often used by drivers to satisfy hunger.

However, bananas are extremely rich in minerals, especially potassium, and eating just one banana a day is enough to maintain normal levels of potassium in the body.

After eating too many bananas, it can cause changes in the ratio of potassium and sodium in body fluids, especially when eaten on an empty stomach, so that the potassium in the blood increases significantly. If the content of potassium in the blood is higher than the normal concentration of millimoles, it will have an inhibitory effect on the cardiovascular system of the person, and there will be obvious sensory numbness, muscle paralysis, drowsiness and fatigue, etc., and in severe cases, heart block, arrhythmia, then driving is prone to traffic accidents, so drivers should not eat bananas on an empty stomach.

This is to pre-cool the bananas, which is a very common way to preserve bananas in transportation, mainly to cool down the banana so that its temperature is not too high.

The purpose of this is to cause the deterioration of the fruit due to the long transportation time, and its role is to effectively increase the time from self-ripening to spoilage.

Fruits like bananas can't wait to be ripe before they can be picked, transported, or sold. Because once the "ripening switch" is activated, the banana becomes unstoppable when it ripens and spoils before it reaches its destination.

For this reason, bananas have to be picked from the tree before they are fully ripe, so that they can withstand the toss of long-distance transportation and long-term storage, and then artificially apply vinyl glass to ripen them before **.

That's formaldehyde, which prevents bananas from ripening prematurely or rotting, what do you think is a good thing!

It can make the flesh of the banana tender.

The reasons why the water turns red after soaking bananas in hot water for a while are as follows:

First: Bananas contain potassium.

Bananas are very rich in trace elements, one of which is called potassium, but potassium is originally soluble in water. When the banana is soaked in hot water, the potassium ions in the banana will be dissolved in the water, and the potassium element will show a purple red color after being dissolved in the water. In fact, anyone who has studied chemistry knows that potassium permanganate is easy to appear purple-red, but in fact, the water here turns red because of potassium.

Second: the dopamine and polyphenols in bananas are oxidized in the air.

In fact, bananas are easily oxidized, even if they are placed directly in the air and not in water, they will slowly be oxidized and turn black. When the cell membrane in the banana is broken, the dismutase substance present in the banana will lose its activity, which is a strong oxidant.

When the dismutase enzyme is inactive, the free radicals in the banana will continue to damage the cell structure, and the dopamine and polyphenols in the cell will be released and gradually oxidized in the air. When these substances are oxidized, they will appear reddish-brown, but when diluted with water, they will appear to be a little red.

Third: Banana peels are oxidized.

In fact, there is also an enzyme in banana peels, and this enzyme is also oxidized. It originally exists in the cells of the banana skin, but because the banana peel is affected by the temperature, the cells will be destroyed, so this enzyme will be released, and when this enzyme comes into contact with the air, an oxidation reaction will occur, and after oxidation, it will turn brown, and with the action of water, it will look slightly red.

Because after a long time, some elements in the banana react with some elements in the air to form this red substance.

Because bananas contain a small amount of potassium, potassium will turn purple red when exposed to water, so bananas will appear red when placed in water.

Bananas contain an element, potassium, which turns red when exposed to water, so bananas will also turn red.

The epidermal cells of banana peels contain an oxidation enzyme that is sealed inside the cells. However, when the banana peel is stored for a long time, it changes from a high temperature environment to a low temperature environment or from a low temperature to a high temperature, the cells crack, and the oxidase enzyme will be released and come into contact with oxygen. Complex chemicals that are oxidized to black.

After blanching, the nutritional value of bananas will be higher, and after blanching, they will turn black and the taste will become softer, and the taste will be softer and more glutinous, which makes people like it very much. When eaten hot, it feels very sweet and has a better taste.

Bananas are high in nutrients and low in calories: Abnormal lifestyle habits are the cause of cancer, high blood pressure, diabetes and other diseases. In order to prevent the occurrence of these diseases, it is not as important to exercise moderately as well as to eat a balanced and nutritious diet.
