Why eggs are easy to spoil after washing with water

There are not only pores on the egg shell, but also a very thin film, which will destroy the membrane during the cleaning process, and bacteria will easily enter the egg through the pores, accelerating the deterioration of the egg.

Branded boxed eggs also do not need to be cleaned, because these eggs have undergone cleaning, disinfection, film and other processes in the factory, which can well ensure the quality of the eggs.

Because there is a protective layer on the outside of the egg, the protective layer is gone as soon as you wash it with water, and bacteria can easily enter through the small holes, and it will be easy to spoil.

The eggshell has many tiny pores that are invisible to the naked eye, and there is a thin layer of corneal protection on the outside of the holes. One of its functions is to reduce internal water evaporation and keep the protein stable; The second function is to prevent the invasion of external spoilage bacteria. Therefore, fresh eggs can maintain the fresh quality for 3 to 4 months under the suitable conditions of 6 10 and 50 60 relative temperature.

However, if the eggs are washed with water, the protective film on the outer layer of the eggshell is destroyed, and the gelatinous substance on the eggshell skin will dissolve in the water, exposing all the holes in the eggshell. In this way, the water in the egg will evaporate, so that the respiration will be strengthened, resulting in the gradual hydrolysis of proteins and lipids with the participation of enzymes. Second, bacteria take advantage of the void to enter, so that the egg protein spoils and loses its edible value.

Therefore, when storing eggs, do not wash them with water, but gently wipe off the dirt on the skin and put them in the refrigerator. If the eggs are washed or cracked, they should be eaten in time to prevent the eggs from spoiling.

That's right! Raw eggs are indeed prone to spoilage after being washed with water. Egg shells are stolen, wash them with water before eating, and it is correct to boil and fry them, but washed eggs cannot be saved.

This is because the surface of the egg is covered with small holes that are invisible to the human eye, these small holes are sealed by a layer of glue but substance, the general bacteria can not enter, and the water in the egg should not evaporate, which plays a role in protecting the egg, if washed with water, the rubber on the eggshell is destroyed and dissolved in the water, and the small holes on the eggshell are all exposed, and the bacteria can enter from the small holes, and live in the egg, destroy the tissue in the egg, so that the fresh egg will soon become a bad egg. Therefore, the eggs you buy cannot be washed with water even if they are dirty on the outside, and the best way is to wipe off the dirt with a rag before storing them. In addition:

Eggs are best stored in the refrigerator, the most appropriate temperature is between 5-7 degrees Celsius, when putting it in the refrigerator, remember to put the big head of the egg up and the small head down, so that the egg can breathe better and prolong the life of the egg.

Because there is a protective film on the surface of the eggshell. After washing, this protective film will not be washed off. Therefore, it is easy for bacteria to enter the egg, and it is easy to spoil.

Because the egg shell contains a large number of calcium ions, under normal circumstances, he can protect and isolate the outside air, so under normal circumstances, the egg is not easy to deteriorate, once stained with water, part of the calcium ions are easy to combine with other ions in the air and hydrogen and oxygen in the water, after the anti-solidification and protection effect is weakened, the egg yolk is like an ordinary thing, it will deteriorate under the influence of external temperature and air, and it will naturally be bad, hehe, I don't know if you are satisfied, thank you.

Because when the chicken lays the eggs, it will use a liquid like glue to protect the surface of the egg shell, if you wash the eggs, the protective film on it is gone, so that the air will pass through the small holes in the eggs to the inside of the eggs, so that the eggs will gradually deteriorate, of course, they are easy to break.

The reason is very simple, because there is a protective film on the surface of the egg when it is born, and after washing it with water, the protective film on the surface will be partially dissolved in water, and the other parts will be washed away by water, and it will be targeted by mosquitoes and bacteria when placed once.

A mosquito bite or a bacterium placed inside will destroy its internal composition, and it won't take long for it to go bad!

There is a protective film on the outer surface of the egg, which is no longer there after cleaning, so it is easy to break if it does not play a protective role.

There is a protective film on the surface of the egg to isolate external bacteria, which will be destroyed by washing, and then the bacteria will invade, and the egg will go bad very quickly.

There are many tiny pores in the egg shell, which are the channels through which the egg cells inside exchange gas with the outside, and those holes are blocked after washing, and the egg cells die because they cannot breathe, that is, the eggs are broken.

The shell of an egg is porous, so if you wash it with water, bacteria will enter the egg. Of course, it's easy to break.

It turns out that there are many tiny holes in the eggshell that are used to breathe the little life in the future. When you wash off the powdered gelatinous substance on the eggshell, the water inside the egg can easily evaporate through the small holes, and the spoilage bacteria on the outside will also take the opportunity to invade and make the egg spoil. On the contrary, the unwashed eggs, because the powder gelatinous substance on the shell is still on it, the small holes on the shell surface are tightly closed, so that the internal moisture of the egg cannot evaporate, and the external bacteria cannot invade, so the egg can still be kept fresh for a long time.

Because there are air holes in the egg shell, there is also a very thin film. Washing will destroy the membrane, and bacteria will easily enter through the pores, causing the eggs to spoil.

The water reacts with the calcium carbonate on the surface of the egg to produce calcium hydroxide, which clogs the shell and prevents the egg from breathing, so it deteriorates.

Because there is a protective film on the outside of the eggshell, the protective film is destroyed after washing. After washing, it is easy to get bacteria.

There is a protective layer on the outside of the eggshell, which plays the role of sealing the pores on the eggshell, which can not only prevent bacteria from entering the egg, but also prevent the evaporation of water in the egg; Keep the egg wash tender. When the eggs are rinsed with water, the "hoarfrost" falls off, bacteria invade, and the water evaporates, causing the eggs to spoil.

Because eggs are not bees', they have pores, so if you wash them with water, bacteria will enter the eggs. Of course, it's easy to break.

It seems to say that there is a kind of glue on the surface of the egg, which cannot protect the egg after washing it with water, and bacteria can enter through the surface of the egg, so the egg is easy to spoil.

The egg is a complete cell, and its surface has stomata for breathing, and when washed with water, it will be immersed in a small amount of water, which will also close the stomata and cause necrosis of the cell. Of course, it stinks!

The eggs just laid by the hen have a protective film on the outside of the eggshell, and after washing, the protective film is destroyed, and bacteria and dirty things are easy to enter. Don't wash the eggs before eating, it's okay if they're a little dirty.

The eggs have a protective film on them, and after washing, bacteria can easily enter the eggshell, so they are easy to spoil.

There are pores on the eggs, and the water may seep into the inside of the eggs after washing, causing them to spoil.

Because there are many small holes in the eggshell, there are many water molecules that will enter the inside of the egg through the small holes when the egg is washed, so it is easy to deteriorate after washing.

The outer layer of the egg itself has a protective film, which is destroyed after washing, and I think it is easy to spoil after cleaning.

There are small holes on the surface of the egg, which can seep into the water, and it is easy to spoil after a long time.

Because there is a microorganism on the surface of fresh eggs to prevent eggs from spoiling, washing eggs with water will wash off these microorganisms and speed up the speed of egg spoilage, so if you don't want to eat the eggs immediately after you buy them, it is best not to wash them with water.

The egg is an organism that requires aerobic respiration, and the water blocks the pores of the eggshell, making it impossible to exchange gases, unable to breathe, and eventually die.

Eggs will go bad when washed with water. Storing eggs after washing can damage the nutritional value of eggs and even spoil the egg liquid. The surface of the egg is covered with small holes that are invisible to the human eye, and these holes are sealed by a glue-like substance, and the natural plastic wrap on the surface of the egg prevents bacteria from entering.

The water in the egg should not evaporate, which plays a role in protecting the egg, washing with water, will destroy the rubber on the eggshell, leading to the invasion of bacteria, which in turn will cause the egg to deteriorate. For dirty eggs, wipe them clean with a cloth.

How to save eggs:

1. Take the eggs home, do not put them in a damp place, and do not put the eggs in a sealed box.

2. Place the small head down and the big head up, because in the egg, one end is empty and there is no egg liquid, which we also call the air chamber. In order to prevent the egg from falling yellow and keeping the egg longer, put the small head of the egg downward, the gas in the egg can reduce the chance of the yolk coming into contact with the shell wall, and it is not easy to stick and scatter the yellow.

Eggs will go bad when washed with water. The surface of the egg is covered with small holes that cannot be seen by the human eye, these holes are sealed by a layer of glue-like substance, bacteria can not enter, and the moisture in the egg should not evaporate, which plays a role in protecting the egg. For dirty eggs, wipe them clean with a cloth.

Eggs are easy to spoil after washing, because there is a gelatinous film on the surface of the eggshell, which makes it difficult for external bacteria to enter the inside of the egg, and if the surface of the egg is cleaned, the film will be destroyed. Not only is the moisture of the egg easy to lose, but bacteria and microorganisms can easily penetrate the eggshell, making it difficult for the egg to be stored for a long time.

Fresh eggs are alive, and they need to breathe through the pores in the eggshell constantly, so they have the function of absorbing anotonic odors. Therefore, when storing eggs, care should be taken to isolate them from other foods.

Eggs are a food that can easily get bacteria, especially if there are contaminants on the eggs, the chance of infection is greater. For example, Salmonella sylvestris is more common, and even if the membrane on the eggshell remains intact, it is still able to penetrate the eggshell and enter the inside of the egg.

Therefore, some regions and countries will require the eggs to be cleaned first, although the channel for bacteria to enter the eggs is opened, but the bacteria on the eggshell, especially Salmonella, can be killed first.

In fact, there is a film on the egg shell, and if the egg is cleaned, the film will be destroyed, not only the moisture of the egg is easy to lose, but bacteria and microorganisms are also easy to penetrate the egg shell, so it is difficult to store the egg for a long time.

Some people ask, why don't some of the clean ones go bad? That's because when chicken farms process eggs, they don't use tap water to clean them, but use professional cleaning and disinfection methods. When the hen lays the eggs, the surface of the eggshell is rough, and after the egg is washed, the egg shell will have an oily protective film, just like apples have wax, which plays a beautiful and protective role.

It is common for people to rinse eggs in water until they are "clean", believing that this is more hygienic. But in reality, this practice is unscientific. If you look closely at the egg or look at it with a magnifying glass, you will see that there are many tiny holes in the shell of the egg, what are they for?

It turns out that if this is a fertilized egg, that is, an egg that can hatch chicks, so that the little life can survive, these small holes are used to allow the chicks to breathe.

It is true that the shell of the egg is dirty, but if the egg is rinsed with water, the shell is very clean, but it cannot be stored for a long time, and it will spoil quickly. This is because the surface of the egg is covered with small holes that are invisible to the human eye, which is sealed by a layer of gelatinous substance, which is not invaded by bacteria, and the water in the eggshell is not easy to evaporate, protecting the egg.

If you rinse with water, the gelatinous substance on the eggshell will dissolve in the water, and all the holes in the eggshell will be exposed, and the bacteria will take advantage of the void to breed in the egg, destroy the tissue in the egg, and make the fresh egg quickly become a bad egg!

Therefore, these dirty-looking things are "hard work"! Therefore, it is important to wash the egg shell to prevent the egg from spoiling.

Eggs will go bad when washed with water. The surface of the egg is covered with small holes that cannot be seen by the human eye, these holes are sealed by a layer of glue-like substance, bacteria can not enter, and the moisture in the egg should not evaporate, which plays a role in protecting the egg.

Eight minutes of boiling eggs is the most nutritious The time for boiling eggs is short, and the yolk is not solidified, so I am afraid that it is unhygienic to eat; After a long time, the eggs are boiled "old", and the taste is not very good. Boil the eggs for 8 minutes just right. Boiled eggs are sometimes difficult to peel, and the reason is that the eggs are not cooked, so the eggs are peeled off a piece of protein protein.

The second is that although the egg is cooked, the eggshell and the egg white stick together, even if the shell is peeled off one by one, the egg white will be brought down, not to mention the time and effort, and it does not look beautiful. For this reason, you can soak the boiled eggs in cold water while they are hot, and then peel them to peel them. (Hard-boiled eggs should be soaked in boiled and cooled water, because the eggshell itself has many small holes, and a large number of bacteria in unsterilized water can enter the eggs through the small holes).
