How long do hard boiled eggs take to boil and how many minutes do eggs have to be boiled to get full

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.

Hard-boiled eggs need to be boiled for about 10 minutes. When the egg is boiled for 3 minutes, its egg whites are slightly coagulated, the yolk is half-cooked, and after 6 minutes, the egg whites are completely coagulated. The eggs are fully cooked.

It is not recommended to boil the eggs for too long, the egg white part of the egg that is boiled too long is older and the egg will become very hard.

When boiling eggs, it is recommended to boil them in a pot under cold water, boiling the pot will cause the eggs to tumble around, which may cause the eggs to crack and the egg whites to leak.

Peeling egg shells can use the principle of thermal expansion and cold contraction, and put boiled eggs into cold water, so that the eggs shrink quickly and make it easier to peel the eggshell.

Eggs are nutritious foods, rich in high-quality protein, lecithin, cholesterol and vitamins, etc., which can enhance memory, protect eyesight, and help **. But in recent years, there have been rumors that eggs are too high in cholesterol and can't be eaten too much, so how many eggs a day is best? How many minutes should the eggs be boiled to preserve their nutrients?

How many eggs is best to eat a day?

First, we need to understand the nutritional content of eggs. A 50-gram egg has about 7 grams of protein, 6 grams of fat, and 82 kilocalories. The amino acid ratio of eggs meets the physiological needs of the human body, it is easy to be absorbed, it is rich in lecithin, which can enhance memory, in addition, eggs also contain vitamin A, vitamin E, phosphorus, zinc, iron and other substances, so eggs are an "ideal nutrient store", and these nutrients are easily absorbed.

Second, the level of cholesterol in the blood is related to factors such as fat content and activity level, and has little to do with daily cholesterol intake. A 50-gram egg contains 188 mg of cholesterol and is mainly concentrated in the yolk part. In order to meet the nutritional needs of different people, and not cause overnutrition, the amount of eggs consumed by different groups of people will be different, such as the elderly can eat 1 to 2 per day, young and middle-aged people engaged in mental or light physical work can eat 2 per day, teenagers and children in the developing stage can eat 2 to 3 chickens per day, and maternity, pregnant women, nursing mothers and even patients, can eat 3 per day, in addition, obesity and three high patients are more sensitive to cholesterol, it is best to consult a doctor before eating.

Finally, it's okay to eat two eggs a day, but people with high cholesterol should pay attention to eating them, and egg yolks are nutritious and should not be discarded.

How many minutes is it good to boil eggs?

The most precious thing in eggs is protein, but if it is cooked for a long time, the protein will be denatured and the nutrition will be greatly reduced. Therefore, everyone should pay attention to the cooking method of eggs in order to maximize the nutritional value.

Before boiling eggs, put the eggs in cold water to reduce the air pressure in the eggs, and wait for the water to boil before starting the timer.

Eggs with different degrees of ripeness will be boiled at different times, and three minutes after boiling, the soft-boiled eggs with soft egg whites but freshly cooked yolks will be boiled, which retains the nutrition of the eggs to the greatest extent, but fails to fully kill Salmonella, and it takes 90 minutes for the human body to fully digest.

After boiling, boil for five minutes, at this time the yolk is slightly solidified, the color is golden yellow, the anti-nutrients are destroyed, and salmonella is also within the safe range, the most nutritious egg.

If boiled for more than 10 minutes, the structure of the protein will be firmer and more difficult to digest, and the sulfide decomposed by methionine will react with the egg yolk to produce iron sulfide that is not easily absorbed, and lose nutrients.

That is to say, eggs that are boiled for five minutes after boiling water are the best, the taste is soft and waxy, and it is also safe, which can better retain the nutrition of the eggs.

Eggs are nutritious, but you can't eat more, you should calculate the number scientifically according to your personal needs, and you should also master the heat of boiled eggs, and the eggs that are boiled for five minutes after the water is boiled are the most perfect.

For the perfect soft-boiled egg, boil the pan under boiling water for 6 minutes. (Soft-boiled eggs may contain salmonella, so it is recommended that the elderly and children with weak gastrointestinal function do not eat them).

7-9 minutes of eggs, the nutrition is intact, salmonella is also controlled and then safe, suitable for all ages.

Precautions. Slow cooking at low temperature can retain the nutrients of the egg to the greatest extent, and the longer it is cooked, the more sticky the yolk will become.

Trick 2 for boiling eggs, soak the eggs in water.

Prepare a basin of water and soak the cleaned eggs in water for about 10 minutes, the purpose of this step is not only to shorten the cooking time of the eggs, but also to make the boiled eggs taste more tender.

Boiled eggs trick three, boil in a pot under cold water.

When boiling eggs, do not put hot water in the pot, the correct way should be to boil the eggs in the pot with cold water. If you boil eggs in a pot with hot water, the egg white on the outside of the egg will be cooked, and the yolk inside will be undercooked, and the sugar will be runny.

Boiled egg skills four, master the heat and time.

When boiling eggs, the heat and time are very critical, after boiling, cover the pot and turn to low heat and cook for about 5 minutes. Don't boil eggs for too long, eggs are easy to get old and destroy nutrients, and if the cooking time is too short, the eggs will not be cooked. So it can be controlled in about 5 minutes.

After the eggs are boiled, don't be in a hurry to open the lid, turn off the heat and simmer for about 8 minutes.

Boiled egg tip five, boiled eggs over cold water.

Prepare a basin of cold water in advance, take out the hard-boiled eggs and put them in cold water for a while, and then remove the eggs and wipe them dry. Doing so makes it easier to peel off the shell of the boiled eggs.

Also, the time taken to cook an egg is also related to the size of the egg, with smaller eggs taking a slightly shorter time to boil, while larger eggs will take longer to get cooked. After boiling the eggs, it is recommended to cool them in cold water, which makes it easier to peel off the shells.

When boiling eggs, you need to pay attention to the amount of water, and generally speaking, round water should be enough to cover the eggs. If you add too much water, it is easy to cause hard-boiled eggs to taste bad. Heat control is also key to boiling eggs.
