Can you still eat eggs after boiling for 20 minutes

Of course, the eggs (rice rolling eggs) can be eaten after boiling for 20 minutes, but they are very well cooked, and they taste a little old and not tender.

Don't eat eggs that have been boiled for too long. If it takes more than 10 minutes, a series of chemical changes will occur inside the egg, and the child will not easily contact with the protein-digesting enzymes in the gastric juice after eating. Therefore, it is difficult to digest and absorb.

Moreover, eggs that have been boiled for a long time will lose nutrients and produce iron sulfide, which is not easily absorbed by the human body. If children with weak gastrointestinal and digestive functions eat it, they will be prone to indigestion, and even.

It is better for children not to boil eggs for too long, the glaze in the egg and the ferrous ions in the egg yolk. In a high-temperature environment, a chemical reaction will occur to form ferrous sulfide, which will easily cause indigestion after children eat it, so it is best to boil eggs for about three minutes, which is the easiest to eliminate and absorb.

Eggs should be boiled in a pot under cold water, simmered for 3 minutes, and soaked for another 5 minutes after the heat is stopped.

In this way, the boiled egg whites are tender, the yolks are solidified and not old, the egg whites are the most denatured, and they are the easiest to digest. Eggs that have been boiled for more than 10 minutes will not only taste old, but also lose a lot of vitamins and make the protein difficult to digest.

There are 3 points to pay attention to when eating eggs.

1.Overnight eggs and tea eggs are not good for the body.

Eggs that are not fully cooked overnight will breed bacteria in them, and if you eat such spoiled eggs, it will be harmful to your health.

Since the protein has been destroyed when it is cooked, and it is overnight, the nutritional value will be much lower. In the same way, tea eggs that are boiled and boiled again should also be eaten less. Because the substances in the tea are mixed with the proteins to produce harmful substances.

2.Don't eat raw eggs.

If you think that eating raw eggs is more nutritious, then you are very wrong, uncooked eggs contain a lot of E. coli, and eating them without cooking them can easily cause diarrhea.

Therefore, eggs should be cooked at high temperatures to kill the bacteria in them before eating. In addition, raw eggs contain avidin, which can affect the absorption of biotin from food, leading to "biotin deficiency" such as loss of appetite, general weakness, and muscle pain.

There is also antitrypsin, which can disrupt the body's digestive function. Another thing to note is to beware of bacteria that get on the eggshells when beating eggs!

3.Eat eggs in moderation.

Although the empirical value of eggs is high, it is not always better to eat more eggs. Eating too many eggs can easily lead to overnutrition, lead to obesity, and increase the burden on the liver and kidneys.

The excess protein will overload the urea manufacturing system, eat too much protein, and will also produce a large amount of ammonia, hydroxyl, phenol and other chemicals in the intestines, which is very toxic to the human body.

It is likely that symptoms such as abdominal distention, dizziness, weakness in limbs, and coma may occur, which is often referred to as "protein poisoning syndrome".

Whether the eggs can be eaten overnight depends not only on whether they are heated, but also when the eggs are boiled for the first time, and only after the first boiled eggs are cooked, there is no problem in cooking them overnight. Tea eggs are this truth, you may not know, tea eggs are boiled twice, the first time cooked, the second time the egg skin is broken, add tea and other accessories, and then cooked, so tea eggs must be cooked, now some people love to eat half-cooked eggs, (egg yolk is semi-liquid) that kind of eggs can not be eaten overnight, even if the second time cooked, do not eat.

If the eggs are not fully cooked, the uncooked yolk is eaten overnight, and in the case of improper storage, the nutrients are easy to breed bacteria, so it will be harmful to health, such as causing gastrointestinal discomfort, flatulence, etc. However, if the food (eggs) is cooked thoroughly and stored at a very low temperature, such as in the refrigerator, it can be stored for more than a week; If it is only stored at room temperature of about 30 degrees, it can generally be stored for 2-3 days, and if the eggshell is damaged, it may only be stored for 1-2 days.

When eating eggs, when you smell a bad smell, please do not eat them again to avoid causing harm to your body.

How long do fresh eggs last?

First of all, we need to know, how long is the shelf life of fresh eggs? There are many people who think that the eggs we eat every day have no expiration date, and that they can be kept for a long time as long as the eggshell is not bad, but this idea is completely wrong!

Generally, it is stored at room temperature indoors in summer, and the shelf life is about 10 days. It will grow a little longer in winter, and the eggs can be stored at room temperature for about 15 days. Is it possible to increase the shelf life of eggs when they are put in the refrigerator?

Studies have shown that when the temperature of the refrigerator is 2-5, eggs can generally last for about 1 month.

Fresh eggs should not be put directly in the refrigerator when they are just bought.

First of all, it is necessary to know that fresh eggs should not be bought and put directly in the refrigerator. Due to contamination from the outside world, there are many kinds of bacteria on the surface of the eggshell. Those eggs with obvious poultry manure and blood spots, and microbial contamination are more serious, if fresh eggs are directly put into the refrigerator, it is very likely to cause sanitary contamination of the refrigerator and even other foods in the refrigerator.

Therefore, fresh eggs that have just been bought should not be put directly in the refrigerator.

Store fresh eggs in the refrigerator and do not wash them.

As I just said, fresh eggs that have just been bought should not be put in the refrigerator, so how to clean them up? Do you want to wash the egg shell with water?

Fresh eggs should not be washed, as they are more likely to spoil after washing! Because the surface of the egg is covered with small holes that are invisible to the human eye, these holes are sealed by a layer of glue-like substance, general bacteria can not enter, and the water in the egg should not evaporate, which plays a role in protecting the egg. For dirty eggs, wipe them clean with a cloth.

Fresh eggs should be stored vertically.

Some experts said that fresh eggs should be stored in the refrigerator with their big head up and small head down, and placed vertically in the refrigerator, not horizontally.

It is not allowed to be eaten, there will be "Bacillus cereus" in bad eggs, and this fungus will produce some poisonous spores that cannot be killed by boiling, and poisonous ring tires that cannot be destroyed by boiling.

1: Spoiled eggs will produce toxins, even if heated.

2: Spoiled eggs will have "yolktoxin" (no explanation for this word has been found for the time being) 3: Spoiled eggs can affect nerves.

4: Hydrogen sulfide gas will be produced.

Eggs can be eaten without changing their flavor.

Yes, but don't leave it for too long, it's okay for a day.

Can't eat it, the protein has gone bad.

I can eat it. When eggs are boiled for a long time, methionine will release sulfide, which reacts with the iron in eggs to form dark ferrous sulfide, causing the surface of the egg yolk to turn green, but it will not cause cancer when eaten.

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

2. The sulfide on the egg yolk does not affect the digestion of egg white. 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.

3. 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 intestine far exceeds the water-insoluble ferrous sulfide on the egg yolk.

It can be eaten, but some nutrients will be lost.

Boiling eggs seems simple, but it is difficult to grasp the heat, too short time will make the yolk undercooked, too long time will make the eggs old and unpalatable. In this regard, according to reports, in fact, the best time to boil eggs is easy to grasp. Cool the pot under water, after the water is boiled for 5 minutes, so that the boiled eggs can kill the harmful pathogenic bacteria in the eggs, and can effectively keep the nutrients in the eggs from being lost.

If an egg is boiled in boiling water for more than 10 minutes, a series of chemical changes occur inside. Proteins become more tightly structured and less likely to come into contact with protein-digesting enzymes in gastric juices, making them more difficult to digest. The protein in the egg contains more methionine, after a long time of heating, it will also be decomposed sulfide, it and the iron element in the egg yolk has a chemical reaction, there will be iron sulfide absorbed by the human body, which is not good for health, and the loss of nutrition is relatively large, not suitable for this kind of consumption.

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 former will affect the digestion and absorption of protein; The latter can bind to biotin in food, resulting in biotin deficiency in the human body, resulting in symptoms such as mental fatigue and muscle aches.

Once the eggs are cooked, the above two substances are destroyed. So many people have the habit of eating raw eggs, which is more harmful to health, everyone must pay attention to this problem, not only to cook, but also not to cook for too long, and it is not correct to cook it incorrectly. Soak the eggs in cold water for a while before boiling to reduce the air pressure inside the eggs; Then boil over medium heat and cold water to prevent the eggshell from cracking and avoiding nutrient loss.

Don't eat it, it's not good for your body.

Eggs can be eaten the next day after they are fully cooked, and they will not deteriorate overnight at room temperature, and they can be stored in the refrigerator for about 48 hours. However, it should be noted that eggs with uncooked yolks are not recommended to continue eating the next day, as such eggs may breed bacteria and cause gastrointestinal discomfort after eating.

Eggs can be eaten the next day after they are cooked, and the boiled eggs will not deteriorate overnight, and they can be stored in the refrigerator for about 48 hours.

It should be noted that when the yolk inside the egg is not fully cooked, it is not recommended to continue eating it the next day, because this kind of egg is easy to breed bacteria when it is not stored properly, and it is easy to cause gastrointestinal discomfort after eating.

When you are not sure whether the egg is fully cooked, you can put the egg on the table and spin it, if the egg spins very quickly, it means that the egg is fully cooked. If the egg is always wobbly and unstable when it rotates, it is not fully cooked.
