With so many eggs on the market, how do we choose fresh eggs?

When we buy eggs, we actually have some tips for choosing fresh eggs: first, the shell of fresh eggs is not cracked, the surface is a little rough, and sometimes there is a residual layer of white powder on the egg shell; Then we can shake the egg, if there is no sound coming out, it is a good egg; Finally, we can also hold the eggs in a bright light, fresh eggs will appear translucent, and stale eggs will appear dull gray.

EggsEggs are the most commonly eaten nutritious food in our daily life, not only have outstanding nutrients, but also have a kaleidoscopic variety of cooking methods, most people have a certain number of eggs stored in the refrigerator for a long time. But many people are often a little hesitant when buying eggs in the supermarket, because they don't know how to pick out real fresh eggs.

Looking at the surface of the egg, you can first look at the surface of the egg to distinguish, the fresh egg shell is very complete, there will be no cracks, and it will feel a little rough to the touch. Generally speaking, the white egg shell will be thinner, and the light brown and dark brown egg shell will be thicker, which is the egg laid by different breeds of chickens, the darker the color, the thicker the egg shell, and the nutritional value of eggs of different colors is also about the same.

Shaking the egg The appearance of the egg is not abnormal, we can pick up the egg with two fingers, put it to our ears and shake it to listen to its sound. The yolk and egg whites of fresh eggs are very intact and shake without sound; If it's a bad guy who has been sitting for a long time, the liquid inside is not so thick, and there will be a little water sound when shaken.

The last way to irradiate strong light is to use strong light, pick up the egg and face the bright window outside, or turn on the flashlight on the mobile phone to irradiate the egg, the fresh good egg will show a translucent appearance, and the yolk protein can be seen clearly; Stale eggs have a greyish color, and the yolk and egg white are not as clear.

First of all, choose an egg and shake it next to our ears a few times, if it has obvious shaking, it proves that the egg is not fresh, it has been broken, if there is no shaking, then it is a fresh egg.

We choose fresh eggs, preferably native eggs, which will taste better and have higher nutritional value than ordinary eggs.

When buying eggs, first look at the appearance of the eggs, whether there is an abruptness of a grain, the more it means that it is fresher, gently shake the eggs without sound, the eggs are complete, and there is a layer of white powder on the matte surface.

Generally, fresh eggs are sold very quickly, and if there are that kind of eggs in the supermarket, it means that they have been put for a few days.

It's best not to buy such eggs, if there is a suggestion at home to throw them away, it's good to know the tips for choosing eggs in time, how to buy high-quality eggs, these kinds of eggs can't be bought, how to choose fresh eggs.

In terms of nutrition. Fresh eggs are nutritionally the most comprehensive. Fresh egg protein contains a substance of proteolytic enzyme, which will hydrolyze the protein in selenoprotein under the action of temperature, and in the form of protein, the nutrients will be gradually hydrolyzed and gradually lose their activity and effect.

Fresh eggs are rich in lecithin and cerebrophospholipids, which play an important role in the development and maintenance of brain and nervous tissue. It also contains unsaturated fatty acids, so phospholipids are susceptible to fat oxidation, resulting in huge losses.

Eggs are also rich in vitamins, and the content of vitamins will decrease as the freshness of the eggs decreases.

In terms of activity. Fresh food is still in the stage of vigorous growth, and the respiration of cells is also the most active at this stage, and the substances that need to be consumed for the growth of life are all present.

In terms of taste. Eggs taste best when they're fresh.

Buying eggs will not pick fresh eggs to teach you a trick, eggs are not fresh at a glance.

The eggs of the five black chickens are of the best quality, and the eggs of this breed are very rich in nutritional value and of particularly good quality.

You can choose domestic eggs, which are born from chickens that eat grain, which is relatively healthy.

It is better to choose free-range eggs. This kind of egg is basically free of chemicals, and the ingredients in it are relatively natural.

Judging by your statement, native eggs.

It should refer to mostly white-skinned, small eggs, known as free-range eggs, slightly higher.

The eggs in the supermarket should refer to the ordinary eggs that everyone buys, mostly red or white, slightly lower. That's the difference.

Nutritionally, it's the same! A few more words on nutrition.

Native eggs generally have a larger yolk, or are claimed to be free-range, so we feel that they must be highly nutritious. In fact, the nutritional content of eggs and eggs is the same, and the difference between different eggs will not exceed five percent. Chickens that grow up eating bugs and grass seeds and chickens that eat feed for a long time have a digestive system in the body.

It is the same, the difference in the nutritional composition of the body is not large (the main thing that determines the nutritional content of chicken is the breed of chicken and the feeding time), and the natural difference between eggs is not large.

Local chickens, that is, free-range chickens, usually taste better than chickens in chicken farms, so everyone will naturally associate high nutritional content, and then will associate the nutritional value of eggs. This is a misunderstanding, and it's all hype. The difference is simply in the taste.

The difference between supermarket eggs and native eggs is mainly the size, skin color, and taste. Nutrition is the same.

If you choose your own eggs, as long as they are fresh and safe, they are good. Relatively speaking, the eggs in the supermarket are purchased from regular chicken farms, and the quality, and safety are ***. The native eggs that claim to be free-range are generally not fixed in the production place, and the safety and quality are not easy to say, and they are not as good as the general eggs in the supermarket.

Your own eggs are nutritious, the eggs you buy in the supermarket are basically foreign eggs, that is, the chickens eat feed and lay some eggs, your own chickens eat corn, and the nutrition of the insects is definitely much better than that of the supermarket.

The easiest way to do this is to hold the egg in your hand and shake it gently, and what is not moving is fresh.

The eggs that have just been laid by the hen are the freshest.

Eggs as a necessity of daily life, basically appear on our table, eggs are rich in protein, vitamins and trace elements required by the human body, one egg a day can provide the human body with a day's energy needs. But for many friends, the choice of fresh eggs has also become a problem, stale eggs will affect the taste, bad eggs are destroyed by the nutrients of eggs, and even cause damage to the human body, is not conducive to people's health, fresh eggs not only taste super, but also rich in protein, so the eggs you buy are fresh?

Place the egg in the water and see if it floats. The egg has a small air chamber, and over time, air will slowly enter the egg through the small holes in the shell. The more air that enters the egg, the larger the air chamber in the egg and the easier it is for the egg to float.

If the egg sinks horizontally to the bottom of the bowl, then the egg is at its freshest. If the egg stands up, but one end is still in contact with the bottom of the bowl, then the egg is past its freshest time, but it is still ready to eat. If the egg floats, then it is not fresh anymore.

But that doesn't mean it's spoiled or inedible. You still need to knock it open and tell if it has gone bad by looking at or smelling it.

The sound of striking the eggshell identifies the presence of cracks and deterioration. The sound of a good egg touching it is solid and calm, like the sound of hitting a brick; There is a sound of empty when the hatched egg knocks on the big head. Take the egg to your ear and shake it vigorously, the sound of the good egg is real and small; Eggs with larger empty heads have a hollow sound; The sound of knocking out eggs is obvious; The preserved eggs are like the sound of knocking on the slag.

Through comparison, broken eggs, dumb eggs, preserved eggs, empty eggs, and water eggs can be distinguished. Sniff the eggs with your nose. Fresh eggs generally have no odor.

By sniffing, you can distinguish between eggs that have a smell of smell, bad eggs, and eggs that are contaminated with peculiar smells such as pesticides.

Eggs feel good when you put them in your hand. Fresh eggs have a rough feel, with a raised surface and a layer of white frost, which is a protective film of itself; Stale eggs feel smooth to the touch in the hand, and will be shiny to the light, such eggs are very stale eggs; There are some black dots on the surface of the egg, and if they come out of the shell, the egg is rotten and cannot be eaten.

First of all, there will be an unpleasant smell in the smell, and secondly, when you pick up the eggs, there will be a sound like running water in the clear fire, which is not very good; When choosing, you should first pay attention to the size and orange of the egg, and you can pick it up and shake it to listen to the sound inside, and then you should carefully observe the appearance of the egg.

There will be some small particles on the egg skin, the egg skin is not smooth, and it will sink into the water when placed in the water, and the sinking speed is particularly fast. When choosing eggs, you should go to a regular supermarket, you can gently shake the eggs to listen to whether there is a sound today, and don't buy too big eggs.

Generally smells very bad. And it's heavy. The skin is particularly dry and you need to pay attention to the color of this egg.
