How to distinguish between this egg and a sheep egg

Generally speaking, you can see by looking at the size that the eggs are big

Difference Between Black Eggs and Regular Eggs:

1. Appearance:

Black eggs are generally smaller than ordinary eggs, and many of the shells of black eggs are green, although some are white or brown. The color of ordinary egg shells is mostly earthy yellow and pale white.

2. The egg yolk is different

The yolk of a black egg is larger than that of a regular egg, and the egg white is more viscous than that of a regular egg.

3. The nutritional value is different

Black eggs are very rich in organic calcium, five times more than ordinary eggs. At the same time, the phospholipids and vitamin B2 of black eggs are also higher than those of ordinary eggs. Black eggs contain selenium per 100g, which is 20 times that of ordinary eggs, and the protein content is higher than that of ordinary eggs, while the cholesterol is only, which is one-third of that of ordinary eggs, and the fat is lower than that of ordinary eggs; And eggs are rich in microbiotics A, E, C and carotene, and do not contain any antibiotic drug residues.

The trace elements zinc, selenium, iodine, calcium, etc., which are beneficial to human health, are higher than ordinary eggs; Therefore, black eggs have higher nutritional value than ordinary eggs and are more suitable for medicinal diet and health care.

4、**

According to industry insiders, real black eggs are about 2-3 times higher than ordinary eggs. The business value of black eggs is higher than that of ordinary eggs, and due to the small production, ** is also more expensive than ordinary eggs. In addition to the white shell and red shell, there is also a greenish eggshell in the eggshell color, which is not found in ordinary eggs.

It is appropriate to eat a few black eggs a day: 1-2 are enough.

Black eggs mainly contain protein, cholesterol and a variety of vitamins and minerals, etc., the nutritional value is very high, but eating too much is easy to cause overnutrition, but also increase the burden of digestion, and the size of black eggs is not large, generally between 30-50 grams, so it is recommended to eat 1-2 a day, which can not only meet nutritional needs, but also will not lead to indigestion.

Difference Between Black Eggs and Regular Eggs:

1. Different appearance: black eggs are usually smaller than ordinary eggs, and many of the eggshells are green, and some are white or brown; The shell color of ordinary eggs is mostly earthy yellow and pale white.

2. The yolk is different: the yolk of black eggs is larger than that of ordinary eggs, and the egg whites are more viscous than ordinary eggs.

3. Different nutrients: black eggs contain a variety of nutrients, organic chemical calcium is six times that of ordinary eggs, cholesterol is very low, is one-third of ordinary eggs, and its cholesterol composition is only one-fifth of ordinary eggs, in addition to iron, calcium, manganese, zinc, iodine, selenium and other nutrients and high vitamin E, phospholipids and vitamin B2 content are higher than ordinary eggs.

4. **Different: Because the nutritional and health effects of black eggs are better than ordinary eggs, the market ** is higher than ordinary eggs, usually 2-3 times.

The main value of ordinary eggs.

1. According to analysis, every 100 grams of eggs contain protein grams, mainly ovoglobulin, ovalbumin, containing 8 kinds of essential amino acids, which are very similar to the composition of human protein, and the absorption rate of egg protein can be as high as 98%, egg yolk is rich in sterols, lecithin, egg lutein and phosphorus, calcium, iron, vitamin D, vitamin A and B vitamins, and each 100 grams of eggs contain 11-15 grams of fat, mainly concentrated in the egg yolk, which is easily digested and absorbed by the human body.

2. An egg has 8% phosphorus, 4% iron, 4% zinc, 6% vitamin D, and 12% of the daily needs of the human body6% protein, 6% vitamin A, 2% vitamin B, 3% vitamin E, 5% vitamin B % vitamin B6, contains as many calories as half an apple or half a glass of milk.

And many of the eggshells of black eggs are green.

(1) Put the egg on the table and twist the egg quickly with your hands. Observe the rotation after leaving the hand: if the egg rotates smoothly, it is a cooked egg; On the other hand, if it does not rotate smoothly, it is a raw egg.

When the cooked egg is twisted, the white yolk is twisted together, so it turns smoothly. Conversely, when the raw egg is twisted, only the eggshell is stressed, while the egg white and yolk are hardly stressed. Newton's first law (law of inertia) shows that egg whites and egg yolks are almost immobile due to inertia.

As a result, the rotation of the eggshell is slowed down by the egg whites.

2) After the egg has been rotated for a period of time, suddenly press the egg for an instant, and immediately withdraw your hand. If it no longer rotates after retracting the hand, it is a cooked egg; On the contrary, if you can automatically turn a few more times after withdrawing your hand, it is a raw egg.

Because when the cooked egg is stopped, the eggshell, egg white, and yolk all stop, and after the hand is withdrawn, it continues to stand still. On the contrary, when the raw egg is pressed, the shell only stops temporarily, but the egg white and yolk still rotate due to inertia. Therefore, after withdrawing the hand, it can drive the eggshell to turn a few more times.

1.First of all, you can put the eggs under strong light and observe whether there are pores on the eggshell, if there is a real one, and if there is none, it is fake. If you can't distinguish it from the appearance, you can open an egg to see if there is a film on the inner shell of the egg.

2.The shell of a fake egg is a little brighter (but not more noticeable) and the real egg is a little darker. After boiling, the shell is peeled, and the fake egg appears rougher, and the real egg is smoother.

Taste the taste, fake eggs have a chemical smell, and real eggs have a faint fishy smell.

3.And there is"Artificial eggs"There are signs of perforation at both ends of the eggshell.

4.When shaking"Artificial eggs"There will be a rattle because of the water spilling out of the coagulant.

5."Artificial eggs"Soon after opening, the egg yolk and egg white will melt together, because the egg yolk and egg white are made of homogeneous raw materials;

6.When beating poached eggs, the egg yolks and egg whites will turn yellow in the pan.
