Whether eggs are stored with their heads facing up or with their heads facing up

When storing eggs, the eggs should be kept with their heads facing up, and it is best to store them in the refrigerator so that they can be stored for a longer period of time. Eggs also have life and need to be breathed, so store them correctly.

Placing the egg with the big head facing up can make the yolk float up and stick under the air chamber, which can prolong the storage time of the egg, so that even if the egg is stored for a long time, it will not be yellowed.

There are many ways to preserve eggs, and the use of good storage methods can ensure the freshness of eggs. There are about 7,000 tiny holes in the shell of an egg that are invisible to the naked eye, and the egg breathes through these holes, just like a human **.

Each type of egg has a large head and a small head, and there are some small round holes in the large head part of the egg, which is where the air enters and exits, called the air chamber. The air chamber has two functions, the first is when the egg is hatched, and the chick breathes through the air in the air chamber. Another effect is that under the influence of external temperature, the liquid volume of eggs will expand and contract.

With this air chamber, when the volume of the egg liquid increases, the eggshell will not be burst.

When storing eggs, don't put them in the refrigerator after buying them home, because there are a lot of bacteria and dirt on the egg shell, so you can wash them before storing them.

How can eggs be washed and then stored? The egg shell has a membrane. It can protect the bacteria from the outside from entering the eggs, so that the eggs can be kept longer.

The big head is up and the small head is down, and it is placed vertically in the refrigerator to keep it fresh for a long time.

The concentrated and sparse distribution of freshly laid egg protein can effectively fix the position of the yolk. With the extension of time and the rise of the outside temperature, under the action of proteases, the mucin contained in the egg white is gradually dehydrated, and the egg white slowly thins out, and then the egg white loses its role in fixing the position of the egg yolk. And because the specific gravity of the egg yolk is lighter than the white, the egg will float up when the egg is placed horizontally, sticking to the egg shell, forming a "yolk egg" or "preserved egg".

If the eggs are stacked with the big head upwards and stored upright, there will be no preserved eggs. Because the large head of the egg has an air chamber, even if the egg white is thinned and the yolk floats, it will not make the yolk stick to the shell. So, stack the egg balls with the ends facing up and the tips pointing down.

The eggs must be placed upright with their big heads up, not horizontally, and not backwards.

An egg is a breathing thing. The pointed part of the eggshell has small round holes, which are where the air enters and exits (called the air cell) and governs the respiration of the egg. Therefore, if the bulging part is turned downward, the respiration will deteriorate and reduce its freshness.

When stored in the refrigerator, keep the side where the tip protrudes downwards, like a boxed egg. If you put it with fish, leeks, celery and other foods with strong smells, the eggs will absorb these smells, and the smell will not dissipate whether you cook or fry them, so be careful when storing them.

When placing the eggs, the big head should be up and the small head down, so that the egg yolk can float up and stick under the air chamber, which can prevent microorganisms from invading the egg yolk.

Purchase skills] 1. You can use sunlight transmission to hold it in a circle with your left hand, and put the egg at the end of the circle with your right hand, and transmit it to the daylight, the fresh egg is reddish, translucent, and the yolk outline is clear; If it is dim, opaque or stained, the egg has gone bad.

3. You can gently shake it with your hands The silent ones are fresh eggs, and the ones with the sound of water are old eggs.

4. You can use cold water to test if the egg is lying flat in the water, which means that it is very fresh; If it is tilted in the water, it has been stored for at least 3 to 5 days; If it stands upright in the water, it may be stored for up to 10 days, and if it floats on the water, there is a possibility that the egg has gone bad, and it is not recommended to buy it.

The nutritional value of eggs is very high, it is rich in high-quality protein, every 100 grams of eggs contain grams of protein, two eggs contain protein roughly equivalent to 3 taels of fish or lean meat protein. Egg protein also has the highest digestibility in milk, pork, beef, and rice. Seeing this, I believe everyone will understand why eggs can always be compared to milk.

In general, the shelf life of fresh eggs is about 1 month, and if they are not stored properly, they can easily deteriorate.

There are also a variety of ways to eat eggs, you can directly boil them for breakfast, you can also fry poached eggs, sugar eggs, sweet wine eggs, steamed eggs, egg wrapped meat, egg dumplings, if you want eggs to be delicious, the premise is that there must be a fresh good egg, so the eggs we buy back when stocking up must be properly preserved.

Oval eggs are divided into large heads and small heads, and when you buy eggs, you can use egg trays, net pockets, foam boxes, deflated pads, and dried pine needles. We don't care how it is loaded, after buying it, we have to check one by one, pick out the cracks and noises, and if the quantity is small, it can be directly stored in the refrigerator.

In the past, never distinguish the size of the egg, do not save the egg when it should be big head down, or small head down, always put it indiscriminately, so the eggs at home will not be put into the bowl for a few days will be scattered into a puddle of water, and then go to buy eggs to ask the boss how to store, the boss demonstrated on the spot, the correct way is to put the big head of the egg up, the small head down, so that the egg yolk can float up and stick under the air chamber, in order to extend the shelf life of the egg, It will not be yellow and odorous for a long time.

After buying the eggs home, gently wipe off the dirt on the surface of the eggs (the eggs cannot be washed with water). Place the wiped eggs in the refrigerator with their heads facing down and their heads facing up. At a temperature of 2 5 , eggs can generally be kept for about a month.

1. Do not wash the eggs before storing them in the refrigerator, and the eggs with dirt can be wiped with semi-wet hair soaked in warm water first. The big head is up and the small head is down, and it is placed vertically in the refrigerator to keep it fresh for a long time.

2. It is best to evenly coat the surface of the egg with a layer of cooking oil, or wrap it in plastic wrap and put it in the refrigerator, which can prevent the evaporation of water in the eggshell and prevent external bacteria from invading the egg.

3. Choose a container to store eggs and spread dry and clean bran on the bottom, or you can choose sawdust or plant ash, put a layer of eggs and a layer of sawdust, and then store in a cool and ventilated place, and the eggs can be kept fresh for several months. It is important to note that it is best to flip it every few days.

4. Bury the eggs in salt to keep the eggs fresh for half a year. It should be noted: a layer of salt and a layer of eggs, the eggs are best separated from each other, and the top layer is covered with salt.

5. Wrap the eggs in plastic wrap and put them in the refrigerator, and the freshness time will be very long.

The placement of the egg should be with the small head facing down, and the large head side is the air chamber;

The big head is the air chamber, and the big head should be placed up and the small head down.

Big head down, head down eggs can easily fall.
