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

When buying loose eggs at the wet market, there are five steps to determine if the eggs are fresh:

Take a look. It depends on whether the egg shell is clean and complete, and whether there are traces of damage or moldy stains.

Two touches. Don't choose eggs that are too smooth to the touch and too shiny on the surface, but choose eggs with a layer of white powder on top of the shell.

Three Akira. Pick up the eggs and shake them, and the eggs are fresh without the sound of water.

Four photos. Illuminate the light and see if there is an air chamber, which is large and not fresh eggs.

Five bubbles. If you put an egg in the water, it will be a good egg if it sinks to the bottom, if it is in a semi-floating state in the water, it will be an egg that has been left for a few days, and if it is completely floating, it will be a bad egg.

Are chai eggs better than regular eggs?

Many people think that chai eggs are not only delicious, but also richer in nutritional value, so they are more keen to buy chai eggs.

In fact, the nutritional difference between chai eggs and ordinary eggs is not big, but the fat content is higher than that of ordinary eggs, which is why chai eggs are better than ordinary eggs - chai eggs have high fat content.

Red-skinned eggs are better than white-skinned eggs.

Regardless of whether it is a red egg or a white egg, a good egg is safe and nutritious. Many people are superstitious about the color of egg skins and believe that red-skinned eggs are highly nutritious. That's a wrong idea.

When a substance called eggshell porphyrin is added to the chicken feed, the outer surface of the eggshell can turn red, and this substance will not have any effect on the internal composition of the egg.

Therefore, the color of the eggshell is deceptive, and people should pay more attention to the nutritional value of the egg itself.

How do I choose fresh eggs?

Take a look: look at the color of the eggshell, how clean it is, whether there are cracks, etc. "The eggshell of a fresh egg is complete and matte, with a layer of white powder on the surface, and there is a rough feeling when you touch the eggshell by hand.

Xu Guiyun said that there are many colors of eggshells, some are pink, some are yellow, and some are green, but in fact, the nutrition is almost the same. Some people think that powder-shelled eggs are the best, but this is not necessarily the case. The shell of a chai egg is pink, but not all pink ones are chai eggs.

The color of the eggshell is related to the amount of eggs produced, and the shell color is usually darkest at the beginning of egg laying, and then gradually lighter. The color of the eggshell can also be changed through selection; White-shell laying hens and brown-shelled laying hens are crossbred, and the eggs laid out are also powder-shelled, and the nutritional value is no different from other eggs.

Therefore, there is no basis for saying that powder-shelled eggs are "chai eggs". In addition, it is necessary to observe the egg noodles carefully, if the egg noodles are black or have feces or cracks, you should not buy them. At the same time, don't buy the egg noodles with uneven color or a lot of pockmarks.

Erhuang: When buying eggs, pinch the eggs with your thumb, index finger and middle finger and shake them, there is no sound of fresh eggs, and there is a sound of bad eggs. If there is no sound, it means that the entire egg air chamber and egg yolk are intact; If there is a sound, it may be stale eggs.

Three light: Hold the egg lightly with your hand, observe the light, the egg white and yolk are 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.

In addition, if you want to judge whether the eggs you have bought home are fresh, you can also use the sinking and floating method. Place the eggs in clean water, point down for fresh eggs. If the surface of the eggs you buy home is not particularly dirty, it is best not to wash them, put them in the refrigerator with their heads facing down.

How to choose eggs correctly? Many people have thought wrong, there are 3 points to keep in mind, after reading the knowledge.

Reading guide: Eggs are nutritious and are a delicacy that many people like, it is recommended to eat one egg every day, so we must learn how to distinguish when choosing, in fact, you can pick high-quality eggs by keeping in mind 3 points, to understand.

Utility coefficient:

Ingredients: Eggs are a common ingredient on our 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.

The eggs selected by these three methods are all fresh and high-quality, and a friend in the background left a message saying that the eggshell color of the eggs is so different, is there a big difference between them? Not really. This is because the yolk and egg white are formed before the eggshell, so the eggshell color cannot directly affect the nutritional composition of the egg, but they can be affected by the genotype and individual quality of the hen at the same time, so the composition of the eggshell may be different for eggs of different colors; For eggs of the same color, there may also be some eggs with lighter shell color and less protein, which has nothing to do with nutrition, so there is no need to worry when choosing.

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

Teach you how to pick eggs.

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

Eggs are nutritious and delicious, but these kinds can't be bought, and they can benefit from early learning.

Eggs are immersed in cold water, and the eggs that sink horizontally to the bottom are fresh, and the tilt is not fresh; Observe whether there is trachoma on the eggshell, fresh eggs are without trachoma, and eggs with trachoma are old eggs; Hold the eggs in your hand and shake them, fresh eggs will not hear any sound.

Tip 1: Get into the water.

The eggs are immersed in cold water, and the fresh eggs sink horizontally to the bottom of the water. This is because after a long time of eggs, protein spoilage will produce a lot of gas, and the water in the egg will also evaporate from the small holes of the eggshell, and the specific gravity will also decrease, and it will naturally float on the water surface.

Tip 2: Observe.

This method is not much difficult to operate, and it is very convenient, we only need to carefully observe whether there is trachoma on the eggshell when we buy eggs, which can be seen if we only need to be careful. If there is, then the egg is not so fresh and then it is not suitable for purchase.

Tip 3: Listen to the voice.

Listening is also a good way to distinguish, hold the egg in your hand, if it is a fresh egg, you will not hear any sound, if it is a bad egg, you will hear a shaking sound, if it is a rotten egg there will be a flowing sound or chirping sound, if it is a crack egg, it will also make a crackling sound.

1. Look at the surface of the eggshell, many of the eggs sold in the market have been wiped clean, and the dirty things have been wiped off.

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, the height of the pants 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.

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.

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

1 5 Step by Step Reading.

The eggshell of fresh eggs is relatively rough, with a layer of frosty powder on the surface, and the old eggshell is smooth and shiny.

Take a gentle breath of hot air on the eggshell, and the good quality eggs have a quicklime smell.

The egg is sandwiched between two fingers and shaken in the ear, and the fresh egg is covered with a solid sound, and there is no shaking feeling.

Observe the eggs against the light, and the color of the eggs is translucent.

Eggs: When the egg yolk is complete and plump in a bowl, the egg white is fresh and sticky.
