Can you eat boiled eggs when the yolk is green, how to cook eggs The yolk will not be green

OK. The yellow-green substance on the outer layer of the egg yolk is due to the methionine in the egg.

Eggs contain methionine, which will decompose for too long to produce some sulfide, and the sulfide reacts with the iron ions in the egg to form dark ferrous sulfide, which is the scientific explanation for the discoloration on the outside of the egg yolk. In fact, this phenomenon is more common in salted duck eggs, and ferrous sulfide will also be formed in preserved eggs, but because the preserved eggs themselves are dark in color, we can't notice them.

And the human intestines also produce hydrogen sulfide and other substances in daily life, so it is a person who has no problem.

It is not uncommon to eat green egg yolks. Generally, when eggs are boiled for more than 15 minutes, the yolk skin will basically slowly turn green, but ferrous sulfide is not a carcinogen, and ferrous sulfide is non-toxic. It is insoluble in water, and even if it enters the human body, it is not easy to be absorbed, and it will eventually be excreted with feces, so don't worry too much about affecting your health; Taking a step back, eggs are about 70 80g, of which the iron content does not exceed 5g, which cannot be completely converted to ferrous sulfide, so the final ferrous sulfide content is very small.

In addition, the so-called "ferrous sulfide can promote fermentation to produce carcinogens" is also baseless and unscientific.

It is best to remove the green layer on the outside of the egg yolk and not eat it, otherwise it is not easy to digest and is not good for the body, and you can eat it by removing the green layer.

That's because if you cook it for too long, it will produce ferrous sulfide, which is harmful to the human body and not easy to eat, and the yellow egg should not exceed 10 minutes.

It's edible.

It's just that it's been boiling for too long.

That is, it is too old, not only the color has changed.

It's also not easy to digest.

So it usually takes 10 minutes to boil eggs.

The boiled egg stone flower has already exerted its strength, and it can't be eaten because the friendship is cooked for too long and the egg yolk is spoiled. In this way, the best way to eat poisonous boiled eggs is 3 to 5 minutes, and the egg yolk will definitely be weak if it is boiled for a long time.

If you want to boil the egg yolk will not turn green, you need to control the heat and master the temperature, so that the egg yolk will not turn green, and the boiled egg must not exceed 6-8 minutes, so that the boiled egg is delicious. Eggs are divided into egg whites and yolks, and egg yolks have substances such as triglycerides, cholesterol, egg clotting and other substances, which have a good effect on the nervous system and physical development.

How to cook eggs whose yolks won't be green:

1. Control the time and temperature

If you want to boil eggs and the yolk will not turn green, you must control the temperature and time, the time and temperature are well mastered, so that the egg yolk will not turn green, and the time for boiling eggs should generally not exceed 6-8 minutes, so that the boiled eggs are delicious, and the egg yolk will not be green.

2. Efficacy

Eggs are divided into egg whites and egg yolks, egg yolks have triglycerides, cholesterol, egg clotting and other substances, which have a good effect on the nervous system and physical development, and egg whites can improve human immunity, help the body resist diseases, and also promote muscles to make muscles strong.

3. Precautions for eating

The cholesterol contained in eggs is 3 times that of egg white, and patients with kidney disease should try to eat less or not at all, because high cholesterol accelerates the growth of prostate cancer, which is easy to cause kidney disease such as kidney failure. People with high cholesterol are at risk of cardiovascular disease flare-ups, and it is recommended to eat less eggs for such people.

Eggs are the most common ingredients in our lives, and there are relatively many ways to make eggs, which can be steamed, fried, and boiled, but the healthiest way to eat is boiled eggs, so boiled eggs have become a must-have for many people's breakfast. Boiling two eggs for breakfast is nutritious and healthy, and it's also quite easy to make.

Boiling eggs is a hassle-free recipe, but it's not easy. The nutritionist explained that the egg yolk is blue because the boiled egg takes too long, or it is left for too long after cooking, forming a chemical called ferrous sulfide, although this substance is said to be harmless to the human body, it is difficult to digest and is not easy to absorb after entering the human body.

After boiling eggs for a long time, the yolk will definitely turn blue; But if the time is short, the egg yolk does not solidify, and many friends can't eat soft-boiled eggs; And it is often difficult to peel the skin; So how exactly should boiled eggs be cooked? 1. Do not boil eggs in boiling water. Protein coagulation and denaturation in eggs do not require a very high temperature, generally 87, while boiling water can reach 100.

When eggs are heated at high temperatures for a long time, the iron in the yolk will react with sulfur to form hydrogen sulfide, and the outer layer of the yolk will have a layer of green substance. 2. Correct way to cook eggs: 1. Add cold water to the pot, and then put the washed eggs into the pot.

2. Add a spoonful of salt and let the eggs soak for two minutes, adding salt can sterilize and make the hard-boiled eggs better shelled. 3. Soak for 2 minutes and close the lid. Bring the water to a boil.

After boiling, boil for another 3 minutes4, after boiling, remove the eggs and soak them in cold boiled water for two minutes to remove the shell.

Don't boil eggs in boiling water. First of all, the boiling water will cause the eggs to tumble around in the pan, which can easily break the eggshells and even expose the whites. Secondly, the protein in eggs does not need a high temperature, usually 60 -87, and the temperature of boiling water can reach 100.

If boiled in boiling water, the egg whites may be as old as rubber. So when boiling eggs, you should open the lid and let the water bubble slightly, not boiling.

Cook for a short time and cool after cooking. Eggs that are fully cooked and have a fully set yolk will take 10 minutes to boil, but if you want a hard-boiled egg with a tender yolk, it will take about 6 minutes. If the eggs are boiled for too long, they will have an unpleasant smell of sulfur.

It is also important to note that the eggs should be cooled with cold water immediately after they are taken out of the pot, otherwise the residual temperature will allow the eggs to continue to heat and become old.

If the eggs are boiled too old, you will notice that the yolk has a layer of green on the outside. This is because the sulfide in the egg yolk reacts with the iron, and there is no harm. As long as you don't cook it for too long, you can avoid it.

When you boil an egg, the yolk inside is green, indicating that you have been boiling it for too long. When boiling eggs, boil the water in the pot under cold water and boil it for another eight to ten minutes, so that the egg yolk will not turn green when cooked.

Cook it in water, don't put any seasonings, cook for 15 minutes, you have to eat it on the same day, it will turn green the next day.

How to cook eggs, the yolk won't be green, I saw one before, that is, someone else said, that is, the egg should be in water. If you boil it and put it down to cook for a few minutes, it will not be green, if you put it down with cold water to cook, it will be green, and then the time must be mastered.

In the case of boiling, the egg should be boiled for a short time, generally about ten minutes, and the yolk of the egg will not change color.

Do not use boiling water to boil eggs, usually 60 -87 can be, and after the eggs are cooked, they should be cooled with cold water immediately, so that the boiled egg yolk is more tender. If you boil eggs in hot water, it is easy to lose the original protein of the eggs, and the eggshells are easy to break.

After boiling eggs for a long time, the surface of the yolk will turn gray-green. This is due to the combination of ferrous ions in egg yolk and sulfur ions in egg whites to form insoluble ferrous sulfide. Ferrous sulfide is not suitable for absorption by the human body, which reduces the nutritional value of eggs.

Don't boil eggs for too long, the best time is seven or eight minutes, beyond the time the yolk will change color, not easy to digest and absorb.

It is very normal for eggs to turn green after being boiled for a long time. Such eggs are completely edible, its nutrients are completely retained, no harmful substances are produced, and the taste is better.

It can be eaten, and the biggest effect of boiling for too long is that the eggs lose minerals, but it will not affect the health of the body.

It is best not to eat such eggs, the yolk is green, indicating that the nature of the egg has changed, and there may be undesirable chemicals produced.

It is normal for the yolk to turn green after the egg has been boiled for a long time, and such eggs can be eaten!

It can be eaten, and generally boiled eggs are put overnight and the yolk will turn blue.

After the yolk of the boiled egg turns green, it can be eaten, do not throw it away, it is not harmful to our human body, and it can be used with confidence.

Especially when boiling an egg, after boiling it for a long time, we peel off its shell. It was found that the yolk was dark green because the egg contains a substance containing iron. And the iron content in eggs is still very high.

But there is also a nutrient called sulfur in the egg white, which is in the process of cooking. This will release the methionine of the egg. When released, it binds to sulfide, which affects the iron contained in the egg.

The yolk in the egg then turns dark green.

Many people boil eggs for too long, and when they open them to see that the yolk is dark green, they will feel that they are poisonous inside. Still others believe that the ferrous sulfide contained in it is a carcinogen. If it is practical, it will cause great harm to one's physical and mental health.

In fact, in our daily life, we often eat this kind of green. There are a lot of egg yolks, and many eggs will be heated and stored for a long time, which eventually causes changes in ferrous sulfide in eggs.

Therefore, in the process of boiling eggs, if it is said that after more than 15 minutes, the yolk in his egg begins to slowly turn green, but this substance called ferrous sulfide does not have carcinogenic components, and ferrous sulfide does not have any toxins, it is not easy to dissolve in water, and it will not be absorbed by the human body quickly. After eating it in the stomach, it will be excreted with your stool, so it has no effect on our health.

And a small egg is about 80 grams, and its iron content does not exceed 5 grams. Therefore, after he ate it, it was impossible to completely say that it was a substance called ferrous sulfide. So, after we ate it, he didn't completely turn into this ferrous sulfide.

And the statement that it does not contain any carcinogens is simply unrealistic, so after boiling wine like this, eggs with green yolks are still edible, and there is no harm to the body.

But if. If the boiled egg is boiled for too long, it will still affect the minerals in the egg, such as its iron content. Therefore, when we boil eggs, try not to boil them for too long, and cook them for about ten minutes.

In fact, it is best to boil the egg for about six minutes, and then let it simmer in the pan for five minutes, so that the boiled egg tastes the best.

You can eat it.

Because eggs are boiled for a long time, methionine will release sulfide, which reacts with the iron in the egg to form dark ferrous sulfide, causing the surface of the egg yolk to turn green.

First of all, there is very little sulfide on the egg yolk, which may become hydrogen sulfide and ferrous chloride under the action of gastric acid, and if it does not react with gastric acid, it is also a water-insoluble compound and will not participate in the metabolic process.

Secondly, the sulfides on the egg yolk do not affect the protein digestion. Methionine is not only found in eggs, it is also called methionine, which is a common amino acid in food and is harmless to the human body.

Finally, the human intestinal digestion process is microbial fermentation, and it is normal to produce metabolic wastes such as hydrogen sulfide and biogenic amines. The amount of hydrogen sulfide in the intestines far exceeds the water-insoluble ferrous sulfide on the egg yolk, so everyone can eat it with confidence.

Boiled eggs are edible when they turn green. It is very normal for eggs to turn green after boiling for too long, and there are no harmful substances produced, and the taste is relatively good.

The yolk of boiled eggs turns green only because the eggs are boiled for too long, so that the trace elements in the eggs react into hydrogen sulfide, although hydrogen sulfide is a toxic gas, but because the egg is very small, there is no substantial harm to human health.

It is a very normal phenomenon for the yolk to turn green when boiling eggs, the main reason is that after boiling for a long time, some substances in it will change color, but it will not be harmful to the human body, on the contrary, it tastes better.

It can be eaten, it should have been cooked for a long time. After a long period of heating, methionine can decompose sulfide, which reacts with the iron in the egg yolk to form green or gray-green iron sulfide around the egg yolk.

It is very important to control the time of boiling eggs, and the yolk of boiled eggs is green and harmful to health.

What is the gray-green substance on the surface of the egg yolk after boiling eggs for too long?

Yes. It is normal for eggs to turn green after boiling for a long time. After boiling at high temperature, the egg white will contain sulfur, which will be combined with hydrogen to produce hydrogen sulfide after heating, which will not only have a strange "rotten egg" taste, but also react with the iron in the egg yolk to form ferrous sulfide wrapped in the outer layer of the egg yolk, and ferrous sulfide is a gray-green substance, so the egg yolk has a layer of light green.

Yes. It is normal for eggs to turn green after boiling for a long time. After boiling at high temperature, the egg white will contain empty blind sulfur, which will be combined with hydrogen to produce hydrogen sulfide after heating, which will not only have the taste of "rotten eggs" that are strange, but also react with the iron element in the egg yolk to form ferrous sulfide wrapped in the outer layer of the egg yolk, and ferrous sulfide is a gray-green substance, so the egg is yellow with a layer of light green.
