There's a lot of learning to save eggs! Can old eggs be eaten

eggs are a kind of food that we often eat everyday. The nutritional value of eggs is very high. But do you know some storage skills about eggs? There's a lot of learning to save eggs! Come and have a look.

Grasp these six points and keep the eggs for another two months

1. The eggs must be stored in the refrigerator correctly.

After you buy back the eggs, you will generally put them in the refrigerator, but the correct storage method is to put them with the big head up and the small head down, so that the yolk will float up and stick under the air chamber, which can not only prevent microorganisms from invading the yolk, but also help to ensure the quality of the egg.

2. Eggs should not be shipped with volatile substances.

Because the strong smell of such substances as onion, ginger, pepper and so on will penetrate into the egg through the pores on the eggshell, accelerating the egg deterioration.

3. The fresh eggs taken out from the refrigerator should be eaten as soon as possible, and should not be stored for a long time or refrigerated again.

Since the eggs will sweat at room temperature after being taken out, the bacteria and microorganisms in the small water drop will soon penetrate the shell of the egg and penetrate into the inner layer of the egg liquid, so the eggs can no longer be guaranteed and should be eaten immediately.

4. Do not wash eggs with water before storage.

Some eggs have dirty shells. People like to store them after cleaning to avoid polluting other foods. However, cleaning will destroy the original outer shell membrane of the egg, make bacteria and microorganisms enter into the egg smoothly, and accelerate the deterioration of the egg. It can be wrapped with plastic bags or film and put again, so as not to cause pollution.

5. There is independent storage space.

When there is no condition to refrigerate eggs, try to make holes in the shape of eggs with clean paper or cloth, so that each egg has an independent storage space, and avoid direct exposure to the air. This can reduce the chance of invasion of bacteria and microorganisms, and prolong the preservation time of eggs.

Don't eat old eggs

The time of egg deterioration is closely related to the temperature and humidity during storage. In the north of China, it can be stored at room temperature for 30-35 days in summer and below 15 ℃ for 40-50 days in winter. Generally, it will not deteriorate. In the South with high temperature and humidity, it may deteriorate after being preserved for 25-40 days. When the temperature is higher than 25 ℃, the time of egg spoilage will be shortened obviously.

The production date of an egg refers to the time when the egg is produced by the hen, not the ex factory date or packaging time. The fresher the eggs, the better the quality. Even within the shelf life, the closer the product is to the marked production date, the higher the nutritional value. There are also some problems on eating eggs that often bother us. Come and see if these problems are often tangled up by you!
