How long will it take for the egg to cook?
The time for boiled eggs was short, and there was no coagulation of the egg yolks. I am afraid it was unhygienic. After a long time, the eggs were boiled and they were not so good. Many people may have a puzzle. How long is it appropriate to cook eggs? How long can you cook an egg? The following Xiaobian introduces you.
"3 minutes egg", mature and tender egg, egg yolk just cooked, slightly simmer. "5 minutes of egg", mature and tender egg white, cooked egg is not hard. The best condition for eating eggs is that the egg white has solidified and the egg yolk is in a semi-solidified or fluid state. This can not only ensure the digestion and absorption rate, but also avoid the loss of nutrients.
1, "3 minutes of eggs" are slightly cooked eggs, the most easily digested, about 1 hour and 30 minutes to digest.
2. The "5-minute egg" is a half-cooked egg. The digestion time in the human body is about 2 hours. If the egg is boiled for too long, the body's digestion will take 3 hours and 15 minutes.
3. The "5-minute egg" is not only soft and tender, but also has a strong aroma of the egg, and it is good for the human body to ingest nutrition. In terms of nutrition, eggs that are boiled for less than 10 minutes have the highest digestibility and no substantial loss of nutrients.
The correct method of cooking the eggs is to cook in a cold-water pot, heat slowly, and boil for 2 minutes. After a ceasefire, soak for 5 minutes. The egg that is cooked out of the egg is tender and the egg yolk is solidified. If you eat boiled eggs, eggs are best boiled tender, that is, boiled and cook for five or six minutes on it, at this time, the egg's egg yolk has just solidified, eat this state of the egg, the body's protein absorption rate is the highest.
Boiled eggs are too long or too short
When the egg is boiled in boiling water for more than 10 minutes, there will be a series of chemical changes inside the egg. The protein structure becomes tight and does not easily come into contact with the protein digestive enzymes in the gastric juice, so it is difficult to be digested. The protein contains methionine, and after prolonged heating, it decomposes into sulfides and reacts with the iron elements in the egg yolk to form iron sulfide and ferrous sulfide. This is why the egg yolk outer layer will produce black and green.
Does the black-green material wrapped around the yolk affect the health? Experts explained that long-term cooking of eggs will lose a lot of nutrition, resulting in iron sulfide and ferrous sulfide is not easily absorbed by the body, children or people with weak digestive function This black egg yolk boiled eggs easily indigestible, and even stomach pain.
So boiled eggs do not exceed 10 minutes, then how to cook the eggs delicious and nutritious? The following Xiaobian teach you 4 skills to cook eggs.
4 Tips for Cooking Eggs
Do not boil eggs with boiling water. First of all, the boiling water will make the eggs roll around in the pot, it is easy to break the egg shell, and even the protein is exposed. Second, the coagulation and denaturation of proteins in eggs does not require very high temperatures, usually 60°C-87°C, and the boiling water temperature can reach 100°C. If boiled in boiling water, the protein may be as old as an eraser. Therefore, when cooking eggs, you should open the lid and allow the water to bubbling rather than boil.
2, the cooking time should be short, after cooking to cool. The protein is fully cooked and the egg yolks are completely solidified. The eggs need to be cooked for 10 minutes. However, if you want a soft boiled egg with egg yolks, it will take about 6 minutes. If the egg is cooked for too long, there will be an unpleasant smell of sulfur. Another thing to note is that when you take the eggs out of the pan, cool them with cool water immediately, otherwise the residual temperature will keep the eggs warm and grow old.
3. Some of Chen’s eggs are better peeled. We all feel that the freshest is good, but boiled eggs do not need to be too fresh. Because the eggs that are slightly older are better peeled. If you store eggs in the refrigerator for a few days, the pH will increase slightly, and the protein and the inner shell will loosen slightly.
4. It does not matter if the yolks turn green. If the egg is cooked too old, you will find that there is a layer of green outside the yolk. This is where the sulphides in the egg yolk react with iron without any harm. As long as the cooking time is not too long, you can avoid it.
Should I eat a few eggs a day?
From a nutritional point of view, in order to guarantee the satisfaction of the body's needs without oversupply, in general circumstances:
It is better for the elderly to eat 1 or 2 meals a day. Young people and middle-aged people who are engaged in mental work or light physical work are more likely to eat 2 eggs a day; they can eat 2 to 3 eggs a day for heavy physical labor and consume more nutrients. Juveniles and children are able to eat 2 to 3 meals a day due to their fast metabolism.
It is best to eat in the morning or at noon to provide adequate nutrition for the day's work and to avoid excessive cholesterol intake at night.
However, people who have problems with their liver and kidney function need to consult their doctors to determine the number of eggs they eat. Because eggs are rich in protein, excessive protein can increase the burden on the liver and kidneys.
