1, the bought eggs must be stored in the refrigerator with the big head up and the small head down, so that the yolk can 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, so the strong smell of such substances as onions, ginger, peppers, etc. will penetrate into the eggs through the pores on the eggshell, accelerating the deterioration of the eggs.

3. Fresh eggs taken out of the refrigerator should be eaten as soon as possible, and should not be stored for a long time or refrigerated again. Because the eggs will sweat at room temperature after being taken out, bacteria and microorganisms in small water droplets will quickly penetrate into the inner layer of the egg liquid through the eggshell, so the eggs can no longer be preserved, so they should be eaten immediately.

4. Don't wash eggs with water before storage. Some eggs have dirty shells. People like to store them after cleaning, so as not to pollute others. However, cleaning will destroy the original outer shell membrane of eggs, so that bacteria and microorganisms can enter the eggs smoothly and accelerate the deterioration of eggs. You can wrap it in a fresh-keeping bag or film before putting it, so it won't cause pollution.

5. 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 chances of bacteria and microorganisms invading and prolong the storage time of eggs.
