How to choose eggs when buying eggs, and how to choose when buying eggs?

Eggs are a common ingredient on our dinner table because of their high level of nutrition, and many people cook one or two for breakfast every morning. So how do we choose eggs when we buy them from the market? There are advantages and disadvantages of eggs, in fact, as long as you master a few skills, even Xiaobai will choose, and I will talk to you today.

Eggs are known to have a high nutritional value, the most important of which is high-quality protein, good B vitamins**, as well as other minerals and trace elements, and is the highest protein in all kinds of foods. However, it is precisely because of its high protein content that it is not recommended to consume too much at one time, otherwise it will still be harmful to the body, and one consumption per day is enough.

So if we go to the market to buy eggs, how do we choose eggs? In fact, just keep these points in mind.

First, shake the eggs. When we buy eggs, we hold down the eggs with our thumb and index finger to shake them, and the fresh eggs without sound indicate that the entire egg air chamber and egg yolk are complete; If there is a sound, it is a bad egg, which may be an old egg, indicating that the egg has been left for a long time or the inside has been moldy.

The second point is to look at the shape of the eggshell. The shell of a fresh egg is intact, without any cracks, there is a layer of white powder on the surface, and there is a rough feeling when you touch the eggshell by hand. If there is a crack, it is best not to buy, the inside may have been infected, the color of the eggshell is many, there are pink, yellow or green, in fact, the nutrition is almost the same.

The third point is strong light exposure. Pick up the egg and face it to the sun or a mobile phone flashlight, the high-quality egg white, egg yolk is clear, translucent, and there is a small air chamber at one end; If it is an unfresh egg, it is gray and dark in color, and the empty chamber is large; Eggs that have aged or gone bad will have stains.

Buy eggs and pick eggs 1, look at the surface of the eggshell, generally many eggs sold in the market have been wiped clean, and the dirty things have been wiped off, so if there are still dirty things on the eggshell at this time, then there is a problem with the eggs themselves.

2. When we pick eggs, we should choose eggs whose shells look smoother and have no impurities on them, if there will be a lot of spots or blood stains on the shell, it means that the chicken that lays the eggs is not healthy, and there may even be some diseases, and the eggs are damp, and there will be some black spots on it, so don't pick this kind of eggs.

3. There seems to be a layer of powdery hoarfrost on the fresh eggs, and there will be a little roughness to the touch, if the eggs are remembered to be put for a long time, the layer of powdery frost on the surface of the eggshell is almost all off, and the eggshell is very smooth to the touch, and this kind of egg is the old egg that has been put for a long time.

4. Pick up the egg and shake it. When shaken, if the liquid inside the egg shakes significantly, like a bottle that is not filled with water, then it is a bad egg. If the egg shakes without sound and is thick, it means that it is a fresh egg, and the yolk and egg liquid in it are not mixed together.

5. Use the mobile phone light to shine it, turn on the flashlight on the mobile phone, then put the mobile phone on the table, and then put the egg on the light, the light transmittance of the egg is very good, and it looks more transparent, then it means that there is no foreign matter in it, if the egg is not transparent at all, then it is likely to be a bad egg.

You can shake it gently, if it is an egg that has not been good for a long time, the egg white and yolk will shake; If it is relatively fresh, the egg white and yolk will not be shaken.

How to choose eggs when buying eggs, do you pick big or small?

But we also know that the quality of eggs is good or bad, even the cheap ones in the supermarket are only a few yuan a catty, and the expensive ones are even as high as 10 yuan a piece. Why is that? How should we choose when buying eggs?

Remember! "Pick eggs" remember these 5 words accurately, and the eggs bought back are of high quality!

1. Look. The shell of a good egg generally remains intact and rounded, with no cracks and no moldy stains.

2. Touch. According to the touch of the egg by hand, you can also distinguish the quality of the egg, many people think that the smoother the egg, the better, in fact, on the contrary, the egg with a rough feeling is fresher, and the egg that is smoother to the touch is stored for a long time, proving that the egg has been stored for a long time and is no longer fresh.

3. Knock. Pick up the eggs by hand, generally speaking, the same size, fresh eggs will be heavier.

4. Akira. Hold the egg in your hand and shake it gently, the kind of eggs that obviously have the sound of water are aged for a long time, and the fresh eggs basically have no shaking.

5. Photo. Turn on the flashlight of your phone, place the egg above the flashlight, and see if the egg has an air chamber under the light perspective, the larger the air chamber indicates that the longer it has been stored, the less fresh it is.

Therefore, when we choose eggs, we should combine looking, touching, checking, shaking, and photographing, and choose eggs with a round appearance, rough touch, heavy feel, no shaking and no air chamber, so that the eggs selected are beautiful and fresh, and all of them are of high quality. In addition, the quality of the eggs can also be tested when they enter the water, the fresh eggs sink and lie in the water, while the old eggs float upright in the water. Have you memorized the above 5-word method of "picking eggs"?

How to buy assured eggs No matter what kind of eggs, the same amount of egg whites and yolks have similar nutritional content. Selecting eggs is not about their nutritional content, but more about choosing eggs with high freshness and less pesticide residues, pesticide residues and bacteria.

Look at the appearance

Try not to buy eggs with sand spots on the eggshell, because the eggshell is thin, and it is very easy for germs to enter the egg.

Listen to the sound

Take out the egg and shake it next to your ear, if there is no sound, it is a fresher egg; The sound of the water shaking is the old egg.

Blister with water

The eggs are bought home, and after a long time, they can be put in the water for testing. Pour a small basin of cold water and put the eggs in the water, the eggs sink quickly to indicate that they are fresh eggs, and eggs floating on the surface of the river should not be eaten.

After opening the egg, the yolk of the fresh egg is close to the semi-circular shape, which is malleable, and the egg white can be seen to be divided into two parts, the fresher the egg, the more significant the egg white junction. Some people say that eggs with unsmooth eggshells are fresher, and it is not possible to tell whether eggs are fresh from the smooth level of the eggshell.

In order to ensure that the eggs are cleaned, many manufacturers will clean, disinfect and sterilize the eggs when they leave the factory, and then coat them with a layer of vegetable oil, so that the egg shell is very smooth. The factor of that is that the chicken birth door and the manure tract are combined, and the egg surface is very easy to retain chicken manure, and if it is not cleaned, the germs in the chicken manure enter according to the air outlet hole on the surface of the eggshell, which then causes environmental pollution, and it is safer to choose to clean the egg.

How to properly store and store eggs

Unclean eggshells are likely to carry viral infections such as salmonella and avian influenza outbreaks. It is best to put the eggs in the packaging bag before storing them to prevent the environment from polluting other ingredients in the refrigerator. If you are worried that cleaning will endanger the storage quality, you can use a dry rag to scrub the eggshell with a lot of residue and tidy, and then seal the bag and put it in the refrigerator for storage.

Shake the egg up and down, if there is no violent shaking, it is healthy. The surface of the freshly laid eggs is very rough, and smooth eggs are not good. Finally, choose a round shape for the eggs.

When buying eggs, you should choose eggs with a rough surface, not too smooth, and you should also choose eggs with no black spots on them, such eggs are better.

We have to choose according to the size of the eggs, the skin of the eggs, try to take some large eggs, and the skin of the eggs is relatively clean, there are no traces of breakage.

Judge the freshness of eggs.

Powder. The shell of fresh eggs is firm and intact, and there is often a layer of powdery hoarfrost, which is not smooth and astringent to the touch, which can prevent bacteria from entering the egg. It should be noted that the brand boxed eggs have been cleaned, disinfected, filmed and other processes before leaving the factory, and the feel is relatively smooth.

Sink. There are many small pores on the surface of the eggshell similar to our sweat pores, and the water in the egg will evaporate through the pores, and external microorganisms can also enter the egg through the pores. For eggs of the same size, the fresh ones are often heavier and have a heavy feel, while the unfresh ones feel light because they have lost some of their moisture.

Penetrate. When the egg is held to the light, it is translucent and slightly reddish, and the yolk outline is clearly visible. Even in the bright light, the eggs still do not show light, and they still look very dim.

Shake. Fresh egg whites are thick and can effectively fix the yolk position. However, with the extension of storage time and the change of external temperature, the mucin in the egg white will become dehydrated and thin, losing the role of fixing the yolk, thus forming a "shell egg".

When picking, gently shake the egg near the ear, if there is no sound, it means that the whole egg air chamber and yolk are complete and relatively fresh, if you can hear the sound of water when you shake it, it means that it has been placed for a long time.

Eggs are delicious and nutritious, which can be said to be a must-have and inexpensive nutritional product in our lives, so we also need to pay attention to some methods when choosing eggs.

Touch the eggs. Fresh eggs have a rough surface, while old eggs have a smooth surface.

Smell the eggs. When buying eggs, you can pick up the eggs and smell them, fresh, good eggs will have a slight quicklime smell, while aged eggs will not have a taste.

Listen to the eggs. Put it in your ear and shake it gently. If the egg has no sound, it means that the egg is relatively fresh.

Soak the eggs in water. Once you have bought your eggs back, you can put them in cold water. If the eggs do not float, they are fresh.

Illuminate eggs with light. If the egg has good light transmission and the color is translucent, it means that it is a good egg.

Methods like the above can help you identify which eggs are good and which are bad. EggsTry to eat fresh and some stale eggs, and the nutritional value will be greatly reduced. Spoiled eggs must not be eaten.

1. Take a look.

First of all, look at the color to judge whether this is a "good egg", generally speaking, the surface of fresh eggs is rougher, and the color is brighter and cleaner; The color of aged eggs is relatively dark yellow, and the shell of rotten eggs is black, accompanied by oil stains, so it is not recommended to buy such eggs.

2. Shake it.

Hold the egg in your hand and shake it a few times, listen to it, or feel it with your fingers, if you feel that the egg white and yolk inside are very solid when you shake it, it means that the egg white and yolk are solid, and this egg is fresh; If there is a shaking sound when shaking, it means that the egg has deteriorated; If the egg is completely broken, it will feel like a half-shelled egg when shaken, so shaking it before buying it is an essential way to pick eggs.

3. If there is a crack, you can't ask for it.

Because the shell and inner membrane of the egg are broken, it is easy to breed a lot of bacteria inside, which not only affects the taste, but also harms the health of the human body, so it is not recommended to buy such eggs.

4. You can't have spots.

Spotted laying hens may be a lack of nutrition, lack of calcium, lack of vitamins or methionine, so the eggshell will give birth to irregular spots, or due to storage for too long, resulting in bacteria attached to it, over time, it will produce spots.

I'll tell you, absolutely for you.

First of all, you can take a look at the shell of the egg, the general red egg can be, to see if his shell is flesh red, if the red is white, then this kind of egg is not as good as the red one, because this white-skinned egg is the egg laid by the chicken itself in the case of lack of nutrition, the shell is relatively thin, easy to break (except for the chai egg, because the chai egg itself is white), and there is to see if it is a new chicken egg, shake it by hand, if you feel that the egg white inside is shaking very much, you can feel its shaking, Then this kind of eggs are not eggs laid by new chickens, in fact, the nutritional value of eggs laid by new chickens is relatively large, our professional chicken farmers in the wholesale eggs are new eggs are to charge more,,, there is an untimely way to judge, that is, after you beat the eggs, put them in a bowl, to see the viscosity, if it looks like a lot of water, then this egg is not a new egg.

Eggs are nutritious, but you can't buy them indiscriminately, which is a good way to teach you the right way to choose eggs.

There is a trick to egg selection! You'll understand after reading it.

With strong light, the whole yolk can be seen is a good egg. Another thing is to look at the eggshell, the eggs with a clean appearance and have not been washed can generally be stored for a long time.

First of all, if it feels a little rough on the surface, it is fresh, if it is very smooth, it is stored for a period of time, and then shake it gently, and don't buy it if it has a sound.
