Washed eggs go bad when taken out in the fridge, why is that?

Because there are actually thousands of tiny holes on the shell of the egg, which are protected by a gelatinous film, the washed egg is equivalent to destroying this protective film, and various bacteria will invade the egg from the small holes in the shell after being put in the refrigerator, so the egg will deteriorate when it is taken out after a while.

Eggs in the refrigeratorEggs are one of the main foods in our daily life, and almost every household will prepare some and put them in the refrigerator. Some people buy eggs back and put them in the refrigerator, and some people feel that the surface of the eggs is a little dirty after buying them, so they clean the eggs one by one, and then carefully put them in the refrigerator. Who knows the opposite, the more these people like to wash the eggs and put them in the refrigerator, hoping that it can stay fresh for a longer time, but the more after taking out the eggs after a period of time, they find that a lot of eggs have gone bad, and those who casually stuff eggs into the refrigerator have not encountered this situation, why is this?

In fact, the reason why eggs spoil is easy to understand, many things in the world are naturally good, and artificial processing or interference will destroy this natural equilibrium. When the egg is laid by the hen, it is born with thousands of tiny holes in the shell, and these small holes are the channels for the egg to communicate with the outside world. On the outside of the egg shell, it is also covered with a thin gelatinous film, which protects all the small holes from being invaded by bacteria from the outside world, and those who wash the eggs and then put them in the refrigerator are actually washing off this protective film, which makes all the small holes on the eggs face bacterial invasion in the refrigerator, so that the eggs are more susceptible to bacterial contamination and deterioration in the refrigerator.

How to prevent egg deteriorationIf you really can't get used to the dirty things on the appearance of eggs, we can also add a little detergent to warm water to wash the eggs, dry the water, and then apply a layer of cooking oil on the surface of the eggs to replace the protective film that has been washed off.

It should be that in the process of washing eggs, there are some damages in the eggs, or when the eggs are squeezed at the same time, there are too many egg impurities, which cause these impurities to enter the eggs before they become bad.

Because fresh eggs, its appearance has a protective film, which can make the eggs last longer, if you wash it off, the eggs are easy to spoil, put it in the refrigerator does have the function of keeping fresh, but once it is taken out, it will deteriorate faster.

In fact, the shell of the egg has a membrane, and cleaning it with water will make the moisture inside the egg easy to lose, and bacteria and many microorganisms will also take the opportunity to enter the egg, so it is recommended to put it directly in the refrigerator.

Because the film on the surface of the egg is destroyed, bacteria and microorganisms can easily penetrate the eggshell, and the egg will spoil.

The eggs we see in the supermarket are washed eggs that have undergone special treatment, not only simply rinsed with water, but also have a coating step after washing. The main material of this membrane is cooking oil, which prevents bacteria from entering the eggs. If we want to keep it longer at home, we can also use this method.

However, even if there is a film on the surface of the egg to prevent bacteria from entering, the egg should not be stored for too long. If the egg is stored for too long, the resistance of the film on the eggshell will decrease, and the bacteria will still enter the egg, causing the egg to deteriorate, and the phenomenon of sticky shell and yellowing will appear, at this time, not only the pathogenic bacteria will multiply in large numbers, the protein will deteriorate and rot, but also produce small molecule poisons such as indole and hydrogen sulfide. In addition, with the extension of storage time, the various nutrients contained in eggs will be destroyed, the nutritional value will be reduced, the taste will deteriorate, and even become stinky.

The time of egg deterioration is closely related to the temperature and humidity when storing, in the north of our country, it is stored at room temperature for 30 to 35 days in summer, and it is stored below 15 for 40 50 days in winter, and it generally does not deteriorate. In the south, where the temperature is high and the climate is humid, it can deteriorate after 25 to 40 days of storage. When the temperature is higher than 25, the time for eggs to spoil and rot will be significantly shortened.

Washed eggs can be stored in the refrigerator for about 20 days.

Summary. This needs to see how long it is, the main component of eggs is protein, which needs to be stored at low temperature to prevent deterioration, the temperature of eggs from the refrigerator is about 7 degrees Celsius, and the temperature will generally rise when they are taken out of the room temperature environment, if it is three or five minutes, it should have no effect on the eggs.

This needs to see how long it is, the main component of eggs is protein, which needs to be stored at low temperature to prevent deterioration, and the chicken and fiber eggs are taken out of the refrigerator and the lead imitation degree is about 7 degrees Celsius, and the temperature will generally rise when they are taken to the room temperature, if it is three or five minutes, it should have no effect on the eggs.

Because the rock orange eggs are stored in a coarse mess, there can be no temperature changes. Due to the principle of liquefaction, the chicken socks eggs taken out of the refrigerator from the cold storage will "sweat" at room temperature, and the bacteria and microorganisms on the surface of the egg shell will penetrate deep into the inner layer of the egg liquid through the egg shell, which will accelerate the deterioration of the egg.

It is advisable not to keep eggs in the refrigerator for too long under any circumstances.

It's best not to eat it, the egg white turns yellow, which means that after a long time, there is a chemical reaction inside the egg, even if it is placed in the refrigerator, the egg will be bad after a long time.

Egg whites are semi-flowing gelatinous substances in the subshell and make up about 57% of the volume of whole eggs. The protein contains about 12% protein, mainly ovalbumin. Protein also contains a certain amount of riboflavin, niacin, biotin, calcium, phosphorus, iron and other substances.

Egg whites are divided into concentrated proteins and dilute proteins. Concentrated protein closure: the part of the egg white close to the yolk, the concentration is higher. Dilute protein: The part of the protein close to the eggshell, the concentration is dilute.

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 put 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.

There are many small holes on the surface of the egg, and there is a film before washing, which is used for ventilation and dustproofing. After washing, the layer is washed off, and the inside and outside of the egg are in contact more, so they are prone to spoilage.

Eggs have tiny pores that allow water to slowly seep in, and the protein is prone to spoilage in a humid environment.
