Is it toxic to wash eggs and put them in the refrigerator? What's the best way to keep eggs?

After you buy the eggs home, will you wash them and put them in the refrigerator? If you think the shell of the eggs is too dirty, will you wash the eggs and put them in the refrigerator? In fact, the eggs are easy to go bad. Let's learn about it with Xiaobian.

Can eggs be poisoned after washing and putting in the refrigerator? It may lead to poisoning.

Washed eggs will be more susceptible to bacterial and virus erosion, thus deterioration, eating poisoning.

Some institutions have done relevant experiments, washing the eggs and not washing the eggs, and keeping them in the refrigerator for 5 days before taking them out. It was found that the yolks of washed eggs were all dispersed with a foul smell after they were knocked open. And the eggs that have not been washed, the yolks are intact and fresh.

How can washed eggs go bad?

Because there are thousands of tiny holes on the eggshell, there is an invisible protective film ('white frost') on the surface of the eggshell, which 'seals' those holes. In this way, it is difficult for the bacteria outside to enter the inside of the egg, and the nutrients inside the egg are not easy to lose. However, if the protective film is washed out and damaged, the bacteria and viruses outside are very easy to enter the egg through the pores, resulting in the deterioration of the egg. If the washed egg is kept in the refrigerator for a long time, the symptoms of poisoning may appear after people eat it.

Is the eggshell so dirty? Maybe some people say that the eggshell is so dirty and there are so many bacteria and viruses. If you don't wash it, how can you eat it?

In fact, don't worry at all. First of all, we don't eat eggshells. Besides, whether it's avian influenza or Salmonella, it's very hot. As long as you eat well cooked eggs, there will be no problem. I really don't think I can see it. I'll wash it with water when I'm ready to use it. Don't wash and save.

Three taboos for egg storage

1. Do not wash eggs with water

Some people think that the surface of the eggshell bought back is too dirty, and even the chicken excrement and other things, they should first wash the egg with water, and then save it. In fact, this is not right. It will damage the nutritional value of eggs and even make the egg liquid go bad. There is a layer of 'white frost' outside the eggshell, which can seal the pores on the eggshell, prevent bacteria from entering the egg, prevent the evaporation of water in the egg, and keep the egg liquid fresh and tender. After washing the eggs with water, the 'white frost' will fall off, bacteria will invade, water will evaporate, and the eggs will deteriorate. Therefore, do not wash the eggs that need to be preserved. When preparing for use, of course, clean the eggshells and then boil them in the pot.

2. Avoid storing fresh eggs directly in the refrigerator

A lot of people are used to putting the eggs they bought back on the shelf of the refrigerator, which can prevent the eggs from spoiling. In fact, it's just the opposite. It's not healthy to put fresh eggs on the shelf of the refrigerator. It's harmful to eggs and other foods in the refrigerator. Because there are Bacillus subtilis, pseudobacillus, Escherichia coli and other bacteria on the eggshell, these bacteria can grow and reproduce at low temperature, while the temperature of the refrigerator storage room is usually about 4 ℃, which can not inhibit the growth and reproduction of microorganisms. This is not only not conducive to the storage of eggs, easy to make eggs rotten, but also cause pollution to other foods in the refrigerator.

The correct way is to put fresh eggs into dry and clean food bags, and then put them on the refrigerator egg rack for storage.

3. Do not store eggs horizontally

Keep the fresh eggs crosswise, easy to 'rely on yellow'. Because the egg protein is thick, it can effectively fix the yolk in the center of the protein. When the egg is put for a long time, the mucin in the protein will slowly remove part of the water and lose the function of fixing the yolk under the effect of protease. At this time, if the eggs are laid horizontally, because the proportion of yolk is lighter than that of protein, the yolk will float upward, close to the eggshell, and become close to the egg or close to the yellow egg. When the yellow egg is cooked, it is easy to disperse the yellow.

The quality of egg preservation is determined by the different arrangement. It's best to store eggs with big head up. The quality of eggs stored with big head up will be reduced even less and they will be fresh and tender. Because the pores of eggs are mainly concentrated on the big end of the shell, and the big end is upward, which can avoid the influence of the egg liquid on the respiration, resulting in the lack of freshness of eggs. And put horizontally, it is easy to see the phenomenon that the yolk sticks to the eggshell, so that when you boil the egg, it is very easy to disperse the yolk.
