Can eggs be washed and put in the refrigerator?

Relatively speaking, eggs can be stored for a long time. The best way to preserve them is to put the fresh eggs you buy in the refrigerator. When refrigerating in the refrigerator, do not wash the eggs with clean water, because there is a protective film on the eggshell, which helps to prevent the eggs from spoiling. If you wash them with water, it will be detrimental to the storage of the eggs. In addition, when storing them, do not place them horizontally, but upright.

1. Eggs should not be stored horizontally

The white of fresh eggs is thick and can effectively fix the yolk in the center of the white. After being stored for a long time, especially when the outside temperature is high, the egg white mucus will slowly lose some of its water under the action of proteases and lose its function of fixing the egg yolk. If you place the egg horizontally at this time, since the yolk has a smaller specific gravity than the egg white, the yolk will float up and get closer to the eggshell, turning it into a sticky egg. Therefore, eggs should not be stored horizontally.

2. Tips for preserving eggs

1. The eggs you buy must be stored properly in the refrigerator .

After buying eggs, people usually put them directly into the refrigerator. However, the correct way to store them is to put them with the big end facing up and the small end facing down. This will allow the yolk to float up and stick to the bottom of the air chamber, which can prevent microorganisms from invading the yolk and help ensure the quality of the eggs.

2. Eggs should not be shipped together with volatile substances .

Because the strong smell of such substances as onions, ginger, and peppers will penetrate into the eggs through the pores on the eggshell and accelerate the deterioration of the eggs.

3. Fresh eggs taken out of the refrigerator should be eaten as soon as possible and should not be kept for a long time or refrigerated again .

Because the eggs will "sweat" at room temperature after being taken out, the bacteria and microorganisms in the small water droplets will quickly penetrate the eggshell into the inner layer of the egg liquid, so the eggs can no longer be preserved and must be eaten immediately.

4. Do not rinse eggs with water before storing .

The shells of some eggs are very dirty, so people like to wash them before storing them to avoid contaminating other foods. However, cleaning will damage the original outer eggshell membrane of the egg, allowing bacteria and microorganisms to enter the egg and accelerate the deterioration of the egg. You can wrap it in a plastic bag or film and then put it away to avoid contamination.

5. There is independent storage space .

When there is no condition to refrigerate eggs, try to use clean paper or cloth to make an egg-shaped cavity so that each egg has an independent storage space and avoid direct exposure to the air. This can reduce the chance of bacteria and microorganisms invading and extend the shelf life of eggs.

3. Eggs also have a shelf life

The time it takes for eggs to go bad is closely related to the temperature and humidity during storage.

In northern my country, it generally does not deteriorate if stored at room temperature for 30 to 35 days in summer and at below 15°C for 40 to 50 days in winter.

In the hot and humid south, it may go bad after 25 to 40 days of storage. When the temperature is higher than 25℃, the time it takes for eggs to spoil will be significantly shortened.
