Boil the eggs for 10 minutes until cooked through. In three minutes, the egg whites are coagulated and tender, and the egg yolk is half-cooked. Six minutes, the egg whites are coagulated, and the yolks are half-cooked.
Eggs are prone to salmonella, and the half-cooked state is easy to cause germs, so the boiling time is controlled to more than 8 minutes.
The temperature of egg yolk coagulation is 68-71, the temperature of egg white coagulation is more than 80, if the fire is too big when boiling eggs, the egg white with low coagulation temperature will quickly solidify and harden outside the egg yolk, thereby hindering the heat from continuing to transfer to the egg yolk, affecting the coagulation of the egg yolk with higher coagulation temperature, so that the boiled egg white is cooked and the egg yolk is not cooked.
If it is boiled for too long and the protein is excessively denatured, the egg will become very hard, which is not tasty and affects digestion and absorption.

Eggs can be cooked by boiling for 5 minutes. It is best not to boil more than 5 minutes after boiling water, if the egg is boiled in boiling water for more than 10 minutes, a series of chemical changes will occur inside, and the protein structure in the gastric juice is more compact, which is not easy to contact with protein digesting enzymes and is more difficult to digest. If the eggs are boiled in a pot under cold water, they usually take about 10 minutes to cook.
Prepare a small pot, pour water first, then wash the eggs and put them in the pot to boil, first turn on high heat to boil the water, and then turn on medium-low heat and cook slowly.
Related introductionsIf you boil eggs in a pot under water, you can actually save a lot of time, and the boiled eggs are not easy to burst. You can prepare a pot of water first, and then boil the water, and then put the washed raw eggs into the pot to boil, do not turn on too much when boiling, generally medium or low heat to boil, boil for 5 to 8 minutes, basically you can cook the eggs.
Microwave eggs will actually take a shorter time to cook, of course, you must pay attention to microwave eggs. Since it is sealed, you can prepare a special microwave box, then pour cold or hot water into it, and then put the eggs in the box and cook for three minutes.

It can be cooked in about 7-8 minutes, but when boiling eggs, the boiling time is different, and the taste of the boiled is also different, for example, the eggs that are boiled for 3 minutes are slightly hard-boiled eggs, only a little bit cooked, the yolk is liquid, and the egg whites are only a little solidified, but they are easy to digest after eating.

10 minutes. Wash the eggs before boiling them, otherwise they will be dirty. Put it in water and boil until the water boils, cook for 5 minutes, the egg whites are mostly cooked, and the yolks are not yet ripe; Cook for 7 minutes, the egg white is ripe, and the yolk is partially ripe, which is often called sugar eggs; Cook for 10 minutes The egg whites and yolks are already ripe, and the taste is just right at this time, if you cook for too long, it will destroy the nutrients of the eggs, and the taste will become old.
Introduction: 1. Shake it.
Shake it gently, there should be no sound when the egg is shaken, if there is a noise or the louder the noise, then it proves that the egg is not fresh.
2. Take a picture.
Turn on the light of the mobile phone and take a look, the egg white and egg yolk should be translucent, and the color should be relatively uniform. If it is photographed, the inside of the egg is gray-brown and opaque, which proves that the egg is relatively old.

Generally, boil the water for 3 to 5 minutes.
Eggs in the cold water pot, due to the different air pressures in various places, there are differences in the time of water boiling, so the timing starts from the time the water boils, and the water is boiled for three minutes.
After two more minutes of boiling, the egg yolk and egg white are ripe, and the egg yolk is cooked but not hard, the time to cook the egg should not be too short or too long, and the microorganisms in the egg have not been completely killed.
If the egg yolk is boiled for too long, the iron in the egg yolk will react with certain amino acids, resulting in the loss of nutrients from the egg.
History of Chicken:
China is the world's earliest domesticated chicken country, at least more than 4,000 years of history, in Hubei, Jiangxi, Shandong, Henan, Gansu and other provinces have found more than 4,000 years ago chicken bones or pottery chicken, Chinese chickens are domesticated by pheasants, there are many excellent varieties, among which nine catties of yellow and wolf mountain chicken are very famous.
Nine catties of yellow, also called Pudong chicken, produced in Shanghai Nanhui, Fengxian, Chuansha area, is a kind of large broiler, feathers, beak, feet are yellow, so also known as three yellow chicken, nine catties of yellow, the individual is extraordinarily large, the meat is delicious, so it is welcomed by the people of the world, and has played a great role in the improvement of the breed of the world's chickens.
First introduced to Britain in 1843, imported into the United States in 1847, the American Rock Chicken is a cross between China's nine-catty yellow and black-and-white American chicken in 1865, Japan introduced Chinese chicken breeds in the Sui Dynasty, and at the end of the shogunate, the nine-catty yellow chicken introduced into Shanghai, and cultivated the old fiber into the famous Nagoya egg-and-meat chicken.
Wolf Chicken is mainly produced in Jiangsu, this kind of chicken breast chicken is developed, imported to Britain in 1872, the famous breed of British Ao Pington chicken is crossed by Wolf Chicken and local chicken, and later Wolf Chicken is imported to the United States and Germany, it can be seen that the ancient Chinese chicken breed has a very great impact on the world.

Eggs are generally boiled for 10-15 minutes to be fully cooked.
If the time is not reached, there is a high probability that the soft-boiled eggs will be made. This kind of soft-boiled egg is not fully cooked, and the parasites and bacteria in it are not completely killed, and after entering the body, it will not only aggravate allergic diseases.
It may also cause parasitic diseases, causing abdominal pain and diarrhea. Eating fully cooked eggs can effectively absorb the proteins, amino acids, vitamins, and minerals in them. It can not only nourish the nerves, improve the state of insomnia and dreams, but also whiten ** and eliminate pigmentation on the face.
Nutrition of eggs:
Eggs are rich in high-quality protein, fat, cholesterol and other micronutrients, making them one of the best nutrients for the human body**.
United States — This authoritative magazine named eggs "the most nutritious breakfast in the world" because in addition to the well-known protein, cholesterol and other nutrients, eggs also contain two amino acids, tryptophan and tyrosine, which can help the body resist oxidation.
Thus, an egg yolk is as antioxidant as an apple, but its calories are only as good as half an apple or half a glass of milk. Eggs are very rich in high-quality protein, and the types of amino acids are exactly the same as the composition of amino acids in the human body, which is conducive to the human body to better absorb and digest the nutrients of eggs.
Moreover, eggs also have many vitamins and minerals that are not comparable to apples and milk. <>

Boiled eggs take 8 minutes to be fully cooked, eggs are generally boiled for 6 minutes to 10 minutes, the time is short, the eggs are not cooked, and the eggs will be old for a long time. 6 minutes, at this time the egg white solidified, but the yolk is not completely solidified, there is a flowing soft heart in the center, the nutrients of the egg can be retained to the greatest extent, but it may not be enough to kill the bacteria.
We usually have to grasp the time to cook eggs:
1.Cook for about 8 minutesThe egg white is cooked, the yolk is slightly solidified, and the color is golden, although the antinutrients are destroyed at this time, but the bacteria can also be controlled within a safe range, and the nutrients are relatively intact.
2.Cook for 10 minutesThe protein in the egg yolk has been denatured, and it will be a little dry and choked when eaten.
3.Eggs are boiled for 3-5 minutesAlthough the egg white on the outside has solidified, the egg yolk is still soft-hearted, and it can still flow freely, and the egg yolk takes about 6 10 minutes before it begins to solidify, and many people say that they like to eat eggs in this state the most.
What matters need to be paid attention to in the process of boiling eggs:
1.Pay attention to the time when the eggs are boiled
When you boil eggs, you must pay attention to the time of boiling eggs, if the time is too short, the egg yolk inside has not completely solidified, at this time it is easy to be infected with all kinds of bacteria, but if the egg yolk is boiled for too long, the nutrients will be reduced, so if you want to cook it completely, it is best to take about 15 minutes, but if you want to eat the best taste, then about 8 minutes is the best choice.
2.Pay attention to the heat of the boiled eggs
Many people think that boiling eggs can shorten the time of boiling eggs if they use high heat, but in fact, this method is wrong, if you use high heat, it is easy to cause eggs to break during the cooking process, so it is best to choose medium and low heat, so it is very easy to grasp the maturity of eggs.
In fact, the taste of boiled eggs that everyone likes to eat is different, so the cooking time is also different, but the best time is basically about 8 minutes, at this time, the boiled eggs have been solidified, but not 100% solidified, the taste and taste are the best, and it can also ensure that the nutrients of the egg yolk will not be lost in large quantities. Personally, I prefer to boil the eggs for eight minutes, and the eggs are very tasty.

Many people like to eat boiled eggs, and boiled eggs have the highest nutrient absorption rate. Not enough, many people don't know the heat of boiled eggs. The time it takes to boil the eggs is very important, and it is necessary to cook them just right in order to have both a rich taste and a good absorption of nutrients.
Let's take a closer look at the time it takes to boil eggs.
1. Eggs are generally boiled for about 7 minutes before they are cooked. Eggs cannot be eaten directly, they need to be turned into mature eggs to remove bacteria before they can be eaten. Considering nutrition, safety and deliciousness, eggs are suitable for boiling until the yolk is soft and solidified.
Wash the eggs and soak them in water, then put them in a pot of cold water and cook them over medium heat for about seven minutes. You can also boil over high heat, turn to low heat, turn off the fire after boiling for four or five minutes, and simmer the eggs with residual heat. After simmering, take out the eggs and put them in the cold water to cool for a while, it is easier to peel the shell and eat.
Hard-boiled eggs are more harmful. Raw eggs not only have the problem of Salmonella contamination, but also have two harmful substances, anti-enzyme protein and avidin. The nutrient absorption rate of boiled eggs is 100%, in order to ensure a balanced diet and meet the needs of the body, boiled eggs are not suitable for eating too much.
Otherwise, it is easy to cause overnutrition, under normal circumstances, it is advisable for the elderly to eat 1 egg a day, and teenagers and children who often use their brains can eat two eggs a day.
2. Do not boil eggs in boiling water for more than 10 minutes. If an egg is boiled in boiling water for more than 10 minutes, a series of chemical changes occur inside. The protein structure becomes tighter, and after a long period of heating, the egg becomes more difficult to digest.
Moreover, there will be a reaction inside the egg to produce iron sulfide, resulting in the loss of nutrients. Prolonged heating will make. Of course, don't boil undercooked eggs, because undercooked eggs contain bacteria that are harmful to the human body, and only when cooked just right, eggs can be both healthy and conducive to human absorption.

Generally speaking, it takes 15 to 20 minutes for a shelled raw egg to be steamed in water. If you want to steam quickly and cook late, you can go to a treasure and buy an egg steamer. This saves about 10 minutes, and the egg steamer can be cooked thoroughly in 10 minutes.
If you are boiling water, it will take about 3-4 minutes. After the water is boiled, put the raw eggs into the pot, the boiling water will quickly heat the eggs, and the egg whites inside will be coagulated instantly, and then just keep it boiling, continue to cook for 2 minutes, turn off the heat and simmer for 1 minute, you can cook a yellow and tender white boiled egg. If you are boiling in cold water, it will take about 5-8 minutes.
Put the eggs in cold water, boil over medium heat, and become soft-boiled eggs for 5 minutes; 8 minutes to become a fully boiled egg.
If high heat is used when boiling eggs, it is easy to cause the air in the eggshell to expand sharply and cause the eggshell to burst; However, if you use low heat, it will prolong the time of boiling eggs, and it is not easy to grasp the age and tenderness of good eggs. Therefore, it is best to boil eggs over medium heat.
When boiling eggs, you can add a little salt or vinegar to the water, a little can do, so that the eggshell can be softened, and the eggshell is not easy to break, and it is easy to peel after cooking.
That starts with the water boiling, 8 minutes.
