The color of the eggshell is related to the season, the feed, the growth and health of the chickens, and the medicine. White-skinned eggs and red-skinned eggs are different in color, their nutritional value is about the same, red-skinned eggs are stored longer than white-skinned eggs, and the main thing to see when choosing eggs is whether the eggs are fresh.
The color of eggs is white eggs, there are red eggs, and red eggs are also divided into dark red eggs and light red eggs, and there are many detailed differences. The color of the egg is related to genetics, and if the eggs laid by the old hen are red-skinned eggs, it is likely that the eggs laid by the hen are red-skinned eggs. This is followed by genetic factors, and what we usually see more is red eggs.
Eggs come in different colors, which are related to the season in which hens are produced, and the color of eggs will change differently in different seasons. The color of the eggs is related to the feed that the hen eats, and after some feeds are eaten, the hens may lay red eggs, and the hens may lay white eggs after eating some feed.
The color of the eggs laid by a hen when she is sick is not the same as when she is healthy. The color of the eggs laid by a hen when she is sick is not the same as when she does not take medicine. The color of eggs has a lot to do with a lot of factors.
Both types of eggs are nutritionally similar, except that the color of the eggshell is different. One is white and one is red. The skin of a white-skinned egg is thinner, and the skin of a red-skinned egg is thicker. These don't say anything about the difference in nutrition.
When buying eggs, whether it is red-skinned eggs or white-skinned eggs, the nutrition is almost the same. We have to see if the egg is fresh, we have to pick it up and shake it, if the egg is not shaking, it means that the egg is fresh. You can also take a look at the color of the egg shell, the fresh eggs are beautiful and shiny, and the stale eggs are dark in color and have black spots.

Eggs are a very common ingredient in our lives, and they are also high-quality proteins in our lives, which can supplement our bodies with protein and other minerals, eggs taste very good, no matter what food is paired with, and eggs are very cheap, and they are one of the high-quality proteins that many people choose. <>
Egg shells have red skin and white skin, the color of egg shells is mainly related to the breed of hens, the way of feeding, whether the eggs are red or white, the main nutrients are protein, fat, vitamins and cholesterol, there is not much difference in nutrition. Therefore, don't worry too much when choosing eggs, because the nutrients of the two are the same. <>
Eggs have a high nutritional value, and they are also one of the best high-quality proteins in our lives, and eggs are also rich in cholesterol, especially the yolk inside. When choosing eggs, don't have too much entanglement in the color, when choosing eggs, you can choose the shell is rougher, because the shell of fresh eggs is rougher, and there is a layer of powdery cream on the shell.
There is no difference between red and white eggshell eggs in nutrition, the color of the eggshell is mainly related to the breed of laying hens, the way of feeding, most of the red eggs are the so-called wood chicken, in our life, the taste is better is the native eggs. The feeding methods and breeds of local chickens are not the same as those raised, and there are certain differences in taste.
The color of the eggshell is genetically determined, and there are only minimal differences between the two colors of eggs, and these differences are negligible. The fat of the red skin is higher, the vitamin content of the white skin is higher than that of the red skin, and the vitamin E of the white skin is higher than that of the red skin. <>
Rather than tangled in the color of the egg is better to change the choice of egg varieties, the taste of eggs is very delicious, eggs should not eat too much, for some people whose work intensity is not very high, eat 1 to 2 eggs a day.

The claim that red-skinned (brown) eggs are more nutritious than white-skinned eggs is incorrect and has no scientific basis.
According to an experimental analysis of a study conducted by Michigan State University in the United States, the color of egg skin is determined by the breed and genetics of the hen. The color of the eggshell depends on the amount of pigment in the eggshell, and if the eggshell contains more protoporphyrin pigment, the darker the color of the eggshell.
However, by analyzing the nutritional value of eggs of different colors, there is not enough experimental evidence to show that red-skinned eggs are more nutritious than white eggs.
-
It is mainly determined by the secretin on the uterus and the processing of the hen's reproductive tract. There is a difference, and there will be different nutritional values depending on the nutrients included.
-
It is determined by the pigment of the eggshell. It doesn't make any difference. Red-skinned eggshells can only indicate that they have been inherited more often, but not that they are more nutritious.
-
The formation of red and white skin of eggs mainly depends on the color of the pigment secreted by the reproductive system of the hen, and some chickens have hemoglobin in their blood.
It is metabolized to produce an eggshell porphyrin.
The shell of the egg laid is the red-skinned egg, which is mainly related to the breed of chicken, and some can not be produced.
Red-skinned and white-skinned eggs have the same nutritional content.
Some chickens that cannot produce eggshell porphyrin substances produce white egg skin, according to the researchers' professional test data, showing that red and white eggs contain protein, fat, and vitamins.
and other ingredients, so the nutritional value of red and white eggs is the same, there is no difference.
Stupid eggs compared to eggs from chickens.
The so-called stupid eggs are the eggs laid by free-range chickens, and the ** on the body will be much more expensive than ordinary eggs, and free-range chickens often eat some grains, insects, grasses and other foods, so the taste of eggs will be delicious, and the nutritional value will be higher.
-
The color of the eggshell itself is white, but the color of the final production depends on the color of the pigment secreted by the uterine epithelium, the last process of the egg in the hen's reproductive tract, and the degree of application to the eggshell will also affect the color of the eggshell. "So! Here's the thing:
There is no essential difference in the nutritional value of white and red eggs, and the internal components are fully developed before the eggshell is colored.
-
Eggs are divided into white and red skin because: 1. It depends on the color of the pigment secreted by the hen's reproductive system; 2. Depending on the type of hen, different breeds of hens contain different genes; 3. It depends on the way the hen is usually fed and the choice of feed. Hope.
-
Because the kind of red skin is dyed, it looks red when dyed with pigment, and white skin is the original color without dyeing, and red is dyed with lambs.
-
There are white and red egg shells, which means that the breed of chickens is different, and the food that chickens eat every day is not the same, so the color of the egg skin is also different.
-
Reasons why eggs have red and white skins:
Depends on the color of the pigment secreted by the hen's reproductive system;
Depending on the type of hen, different breeds of hens contain different genes;
It depends on the way the hen is usually fed and the choice of feed.
-
If the chicken cake is white and red, it is some normal situation, and it is because of some genetic differences, or the wood on the side.

In the past, red-skinned eggs were the so-called firewood chicken, and white-skinned eggs were laid by Laiheng chickens, commonly known as foreign chickens, red-skinned eggs were green and thick, and white-skinned eggs were thin, and people thought that red-skinned eggs were highly nutritious.
-
Red-skinned eggs are mainly caused by the secretion of the reproductive system.
Chickens are of different breeds, so the pigment will be darker if there is a deposit.
White-skinned eggs are very common.

Why do egg shells have white skin and red skin? In the past, red-skinned eggs were the so-called firewood chicken, and white-skinned eggs were laid by Laiheng chickens, commonly known as foreign chickens, red-skinned eggs were green and thick, and white-skinned eggs were thin, and people thought that red-skinned eggs were highly nutritious.
-
Answer: Hello, the egg shell has white skin and red skin, mainly related to the breed of laying hens.
-
Because the breed of hen is different, the color of the eggshell is also different.
-
That's right, there are white eggs and red eggs, white eggs are generally laid by native chickens, and red eggs are artificially made eggs, called artificial eggs.
-
Different shells represent different varieties of eggs. There is also a slight difference in nutritional value.
-
1. The color of the eggshell comes from the last processing process of the egg in the hen's reproductive tract - the pigment secreted by the uterine epithelium, such as ovoboriphyrin to provide brown color and biliverdin to provide green. The exact pigment secreted depends first of all on the genotype of the hen.
2. Secondly, it depends on the acquired factors such as the diet and health of the hen. Since the yolk and egg whites are formed before the eggshell, the color of the eggshell cannot directly affect the nutritional content of the egg.
3. The age and health status of the hen will also have a certain impact on the color of the eggshell.
Extended Information: Common Colors of Eggshells:
1. White-shell laying hen breed: It is a cross-breeding based on white single-crowned chickens, which is characterized by early production, small size, high egg production, low material consumption, suitable for high-density feeding, and the disadvantage is neuroticism and susceptibility to stress.
2. Brown shell laying hen species: most of them are egg-meat chickens, which have the advantages of docile, heavy body and strong anti-stress ability, and the disadvantage is that the feed intake is large, and it is easy to form fat deposits if not properly managed.
3, pink shell laying hen breed: its parents for the white shell layer of the laying hen line, brown shell layer strains, the color of the eggshell between the two is pink, the advantage is that the egg production is high, the egg is heavy, the consumption is less than the brown shell layer, the ability to resist stress is strong.
-
There is no difference between white-shelled eggs and red-shell eggs except that the eggshell color is different. The color of the eggshell is entirely genetically determined and is closely related to a substance called eggshell porphyrin. In some chickens, hemoglobin metabolism in the blood can produce eggshell porphyrins, and the eggshell is light red.
Some chickens do not produce eggshell porphyrins, so the eggshell is white. Therefore, there is no direct relationship between eggshell color and nutritional value, and there is no need to worry about eggshell color when buying eggs.
How to pick eggs:
1. Look at the appearance: Don't buy eggs with sand spots on the eggshell, because its eggshell is thin, which is easy for bacteria to enter the inside of the egg.
2. Listen to the sound: Pick up the egg and shake it in your ear, if there is no sound, it is a fresher egg. The sound of water swaying is Chen Dan.
3. Blister: If the eggs are bought and put away for too long, they can be tested in water. Pour a small basin of water and put the eggs in the water, if the eggs sink quickly, it means that the eggs are still fresh, and the eggs floating on the water are not edible.

The color of the eggshell is genetically determined and is not directly related to the nutritional value of the egg. There is no nutritional difference between red-skinned eggs and white-skinned eggs.
The nutrition of white-shell eggs and red-shell eggs is almost the same, and the main nutrients of eggs are protein, fat, cholesterol and some vitamins and other trace elements. Different varieties of eggs can indeed have some nutritional differences, but this difference is small and even negligible.
So when you go to the supermarket to buy eggs, don't think that white-shell eggs are more nutritious than red-shell eggs, their nutrition is about the same, it is not wise to pick eggs based on color, just pick some fresh eggs.
Precautions for eating eggs.
The protein in eggs is a complete protein, which can be decomposed into the body to produce more extra heat, so after eating eggs, the heat production in the body of the fever patient increases, and the heat dissipation decreases, which is like adding fuel to the fire, which is not conducive to fever. Moreover, the secretion of digestive glands in patients with fever is reduced, and the activity of various digestive enzymes decreases, so they should eat a light diet and eat less foods containing high protein.
Although eggs can protect the liver, for hepatitis patients, eating more egg yolks will increase the burden on the liver, which is not conducive to **. Because egg yolk contains fatty acids and cholesterol, the burden on the liver is too heavy, which is not conducive to the recovery of hepatitis, therefore, hepatitis patients should not eat egg yolk.
Eggshell can usually play a role in strengthening the body during calcium, anti-inflammatory and pain-relieving and other effects and functions, eggshell belongs to the protective layer of eggs, mainly composed of protein fiber, during the use of the body usually has certain benefits, can generally be used to assist conditioning or assist ** body or disease, their own disease is more serious also need to actively cooperate with the doctor to use targeted programs**. >>>More

Yes, but very little, the eggshell is composed of calcium carbonate, but because vinegar is an acetic acid solution, acetic acid is originally a weak acid, and after mixing a large amount of water to become vinegar, the acidity is even weaker, so the concentration of hydrogen ions that react with carbonate is very low, and the carbon dioxide produced is very small.

I grew up in the countryside, and I still know the life of chickens, ducks and geese, in the countryside, the farmers' chickens, ducks and geese are usually stocked in the wild, and they are outside all day long with their paws to eat, and of course they will be fed at home. When you slaughter them, you will find that they have a lot of pebbles in their stomachs and other things, which are used to help them digest and replenish calcium. >>>More
