When do you go to the store for eggs, do you take white or brown? Color affects your preferences? Perhaps you buy white, because since childhood they are accustomed to them. Or you from somewhere learned that brown is better, and now we take only them. But what is the difference in fact?
Difference in Kurit
When it comes to color, a key factor is the chicken breed. Simply put, chickens with a white plumage will postpone white eggs, and those whose rest is reddish-brown - brown. There are even breeds that lay less common blue, or spotted, eggs.
Brown egg is better than white?
Color is not a quality indicator. If we are talking about taste and nutrition, there is no difference between white and brown eggs.
In brown eggs shell thicker?
The shell of eggs of both colors has the same thickness. If you ever noticed that the shell is thicker - this is the effect of the age of the chicken, which has postponed it. Young chickens lay eggs with a thicker shell, while the eggs of older chickens have a thin shell. This applies to both white and brown eggs.
Why are brown eggs usually more expensive?
There is an opinion that brown is more expensive than whites, because they are more natural. In fact, it is not. Brown eggs are usually more expensive, since the chickens with brown plumage have a larger size and, accordingly, require more feed.
Little nuance
However, there is one small nuance. Many people say that brown eggs are tastier, as they tried such eggs in the village. But here, the color does not play any role - the fact is that in the villages most often you can find chickens with brown plumage, and a richer taste depends on the fact that homemade chickens are fed much better than those used for the mass production of eggs .
Have you ever wondered what kind of eggs depends on chicken? After all, there are shells of different color both white and all brown shades. What is it - different varieties of eggs or a sign of quality? Let's try to figure out what affects the shell and yolk pigmentation. And at the same time, find out why you should not choose this product, pushing out the color.
The factors defining the color of the shell
Among the orders there is an opinion that the composition of brown eggs is more natural, so to speak, homemade. In fact, the quality of the product produced by a non-dryer depends on many factors. But the color does not affect the taste or qualitative features of eggs. Conversely, the conditions of detention and feeding the chicken in no way reflect on the color of the future glazing. And yet, what does the different color of chicken eggs depend on?
Factor 1. Breed
So, the color of the shell in the products that are carrying homemade and industrial chicken depends on the bird's breed. In this case, the ability to carry eggs of a certain color is laid genetically. That is, the same chicken throughout its life produces fruits with a shell of any specific color. And often there is such a pattern: the color of the shell depends on the tinting of feathers.
So, lacking with white feathers are mainly carrying white, but ripple and golden birds are brown. To certainly find out which coloring eggs will have eggs from your chicken, look at the ear of the ear. If it is white, then the eggs will have the same color. Curia with the Red Village, the color of the shell will be a brown shade.
For each breed, some color characteristics are inherent. So, the leggores and Russian white have a white blossom, and they have the same color shell. By the way, these breeds differ in the greatest eggs. That is why protein product with a white shell predominates in stores and markets.
In the household prefer to carry birds, capable and eggs to carry, and confidently adding in weight. Such rocks mainly have a brown color, respectively, the eggs for them acquire the same color. These include Dominican Nursing, Rhode Ayland, Orpington and other meat-egg chickens.
For some reason, people had the opinion that the time the homemade eggs have a brown shade, then this is a sign of their naturalness. One way or another, this stereotype is laid on the subconscious, and has nothing to do with common sense. But farmers bring new breeds that wear well and give the eggs of a brown shade to win the buyer's favor.
By the way, we are all used to seeing chicken products with a white and brown shell. And in South America there is a specific breed of chicken, which carries bluish-green eggs. The chickens themselves look very original: they have no tails, but on the head feather decorations were formed due to the mustache and beard. The breed has the name "Araucan" - in honor of the names of the Tribe of Indians, which bred such chickens.
In the middle of the last century, the testicles from Arakan chickens received unprecedented popularity, and why all? Among the Americans there was an opinion that the protein product of these wicker pieces contains several times more beneficial substances, and the cholesterol level, on the contrary, is significantly lower than in conventional eggs. However, later studies have shown that the chemical composition of such eggs is no different from others, and the excitement passed.
Factor 2. Environment
The intensity of coloring the shell varies from pale, cream shades to saturated reddish. What does it depend on? The color of the shell influence various external factors: air temperature, stressful situations, diseases. A brownish shade gives a pigment called Protoporphin. It is contained in hemoglobin and various vitamins, is quite common in many forms of wildlife.
The more time spent on the passage of the fetus through the ovage, the more intense it is painted. This happens because Porphyrin acts longer on the shell. Also, the color intensity depends on the egg laying period: the first is usually darker.
Scientific studies have proven that the color pigment affecting the formation of the color is in the nashelnaya uterine organ cells. Therefore, the color of the shell is determined at the initial stages of the formation of eggs.
What affects the color of the yolk?
The color of the egg yolk is sometimes worried about both beginners and experienced owners. Let's figure out why in one egg yolk yellow yellow, in the other there are a bright rich shade, and in the third can be a poisonous orange yolk.
The yellowing of the yolk is a consequence of the effect of pigments belonging to the group of carotenoids. Carotenoids belong to natural pigments and give color plants and fruits. In this case, not all types of pigment affect the color of the yolk. For example, beta-carotene, which makes the carrot orange, will not affect the shade of the yolk. But the pigments of Lutein or Xanthophil are able to achieve a bright color of egg yolk.
The color of the yolk depends on the diet of the bird. If the chicken will use food rich in yellow pigment, then the yolk will have a more rich yellow or orange shade. Such an effect gives corn bright yellow varieties, herbal flour. If you breach with pale corn and alfaling varieties, then the tinting of the yolk will be pale yellow. When feeding, colorless feed and yolk will be with a barely noticeable yellow tint.
This indicator is not a sign of freshness, naturalness or nutritional value of the egg product. But the manufacturers of eggs for sale are trying to feed the lack of bright painted foods so that the product looks more attractive to the buyer. An interesting fact: the yolk contains for some reason more protein than in the protein itself, so the use of yolk is not measured by a tint.
Simple chemical processes explain why chicken eggs are different shades both inside and outside. And these factors cannot become decisive when choosing a rich protein product to your table.
Video "Myths about chicken eggs"
A few myths concern a chicken product in the video.
Despite the diversity of the breeds of chickens, among which there are representatives of all kinds of colors, from Iscin-black to intense yellow, mostly, the eggs are laying two colors: white or all sorts of shades of brown. What does chicken egg shell depend on? What makes yolk yellow? Should this product be bought, guided by the color gamut exclusively? Clarifications of these issues are in the field of oology - science engaged in the study of eggs.
Before proceeding with coloristic issues, it should be understood in the structure of the egg. Shell, protein and yolk -3 components of a ripe egg, located in a ratio 12:56:32 in relation to each other. If you do not take into account the outer shell, the proportion of the protein is 64%, and the yolk is 36%. Scientists came to the conclusion that 90% of the shell is filled with calcium carbonate, and the remaining 10% comes to magnesium, phosphorus, zinc, potassium, silicon, molybdenum, sodium, manganese, copper, aluminum, iron, fluorine, sulfur and other elements of the Mendeleev table .
From the outer side, the egg is shrouded in a suprupny film, which is dried mucus. This protective layer prevents moisture output and prevents the impact of malicious microbes. Inside there is another "checkpoint": a superal film holding a protein and an excellent filter for microbes. However, it is open to air and the lively moisture necessary for the formation of the egg. Completes the natural "checkpoint" soft protein film.
The shell in thickness is 0.3 - 0.4 mm: on the sharp end of the egg it is more dense, compared with the blunt end. The compactness of the egg shell depends on the period of the egg layout: at the beginning of the process, it is thicker, and it gradually thinned to its completion.
Color gamut eggs, as well as the color of the plumage, are laid at the genetic level. The chickens, as well as the other domesticated feathered, shade of the shell is due to the affiliation to one or another.
Brown appears on the shell under the influence of protoporphyrin. Most often, this coloring substance can be found in hemoglobin and vitamins. It takes part in the synthesis of the cells of the uterine mucosa in the process of forming the shell, so the shade is laid at the initial stage of this process. The more clock the journey of the eggs on the egg, the more intense it becomes its color.
The factors affecting the color of the shell
In part, for the color of the eggs in one or another, the meaning of the ration of feathered: the lack of some varieties of amino acids can lead to a decrease in color saturation. Also at its concentration affects the stage of the egg laying, since the shade of the first eggs is usually more saturated. However, the most important factor in the shell color is the affiliation of the chickens to some kind of breed.
It is enough to trace the parallel between the color of the feathers and the color of the shell: white-fledged female performances give white products, and the chicken-row of the other shades shall be carried by brown testicles.
Any kind of chickens are characterized by concrete color characteristics. For example, the famous neurgorns or Russian white plumage is painted in a snow-white color, respectively, their eggs will be the same shade. Considering that these breeds demonstrate the magnificent indicators of egg production, on the shelves of shops prevail the eggs of the color of snow.
Chickens Legergor
The minoron chickens were brought as an egg cross with high productivity characteristics. In addition, they have excellent adaptive abilities, have a moderate appetite and do not require a lot of space in the chicken coop. We understand how to properly contain and feed the "neurgorn". And in the article "" We will get acquainted closer with dwarfed chickens.
In private farms, with the aim of increasing economic profitability, preference is preferred by the rocks of meat-egg direction, which has preferably fawn or brown color, like non-masters of breeds Rhineyland, for example. Therefore, in the minds of the average alignment, a logical chain was entrenched: brown eggs \u003d home, and therefore natural product. However, in practice, this formula does not work.
There is a method of checking, giving 100% result: a white uha dump is a guarantee of white offspring. The owners of the red ears give the products of brown shades.
South American continent is a happy owner of an exotic breed of chickens carrying blue eggs with greenish tump. In addition to the original color of the shell, the naughters themselves also look pretty unusual: they have no tails. The absence of appendages on the back of the body, apparently compensated by a mustache and beard. The name of the threshold of Araucan originated from the same name of the Indian tribe, universally built this type of feathery. A few decades ago, this wonderful product has acquired unprecedented popularity thanks to the erroneous stereotype. It was believed that in this product there are much more nutritious elements than in the eggs of familiar shades, and the level of cholesterol, on the contrary, is much lower. However, recent studies denied this consumer cliché.
Breed of chickens Araucan and Ameraucan
Kura Araucan are known worldwide with an unusual color of their eggs. However, many breeders believe that green eggs are not the only one for which this cross can love. Want to know what else is unusual in these chics? Read our article about. By the way, "Araukan" has a related cross - , which appeared by crossing Araukan with local American churars.
In addition to the breed, the environment is influenced by the environment, the tendency of non-success to various diseases and even stressful situations. These circumstances can significantly affect the intensity of the color, giving the shell of the tender-cream, then bright brick shade.
What does the color of the yolk depend on?
In addition to the color features of the egg shell, housewives are interested in the color of the yolk, which varies from light yellow to golden and bright orange. If the Protoporphyrin "worked well" above the brown shell, then the yellow shade is in the safe hands of carotenoids. However, not all representatives of this group of pigments are given the power to cast yolk in bright colors. For example, beta-carotene, making carrots such an orange, has no effect on the yellow thick substance. But the pigments with the unusual names of Lutein and Xantofil are directly involved in the gland color.
Coloring is caused by the power system: when the chickens are powered by plants, in large quantities containing a yellow pigment, then the yolk will acquire a more rich shade. It is possible to achieve such an effect using corn saturated yellow varieties or herbal flour. If light corn or alfalfa varieties or alfalf will be prevailed in the power circuit, the pallor of the color is transmitted and the yolk. If the power is based on colorless feed, the yolk will be almost transparent, light yellow shade.
The color of the yolk, like the color of the egg shell, does not have absolutely no effect on the quality of products. However, breeders engaged in the breeding of navels are trying to give the yolk intensive color, therefore they feed the chickens of feed containing a yellow pigment. In addition, the researchers concluded that the yolk contains protein in large quantities, rather than the protein itself, therefore, its benefits in no way depends on the shade.
Popular questions about chicken eggs
With the help of simple chemical processes, it is possible to explain to many issues and mysteries associated with the germinal form of animals, bought in the shell - egg, if we speak with the usual language. The most common topics of discussion of hostesses are considered to actively use this product in culinary purposes.
The shell of white eggs is larging than brown?
The strength of the shell affects 2 factors:
- age of Nonaching;
- the volume of calcium in food.
It was observed that with an increase in the age of the chicken begins to carry more brittle eggs. Seasonality also affects the quality of the shell: in the spring, when the state of the body is worse after the winter period, the probability of accidentally split the egg is significantly increased.
Rules marking eggs
Any factory production egg is equipped with marking. The factory "stamp" begins with a capital letter, which indicates the duration of the storage period. The figure is following it, means a category responsible for size. For example, "D" means a dietary egg, which is desirable to implement for 1 week, and "C" - a table, suitable for up to 25 days. Depending on the categories, the weight of the egg varies from 35 g to 75 g or more.
What color eggs are more useful?
There is a widespread opinion, especially in the circle of housewives, which brown eggs are more natural. However, the quality of the product is influenced not the color, but the features of the content and composition of feed. It was notified that among brown eggs often come across copies with blood specks.
Are there any eggs with green yolks?
A greenish shade, which is formed on the yolk in the process of preparation, does not affect its taste properties. However, they should not be boiled too long, since the quality of the protein may worsen: the optimal time for cooking is not more than 10 minutes. Recommend to use exceptionally fresh eggs. Also prevented the greening of yolks will help their instant cooling after cooking.
Which country boasts the greatest meal consumption?
The country is the most interested in egg products - Mexico: every resident of this sun-thank edge eats about 22 kg of eggs annually. A few decades ago, the "egg" ratings headed Japan: each islander consumed at least 320 eggs per year.
How does the yolk are not glued to the shell?
The protein is formed from 3 layers: relatively durable central and enveloping its watery formations, external and internal. In the region adjacent to the yolk, the protein is a concentrated form, in comparison with the zone located directly under the shell. In the layer in contact with the yolk, with two edges, elastic codes are formed. It is they who fix yolks in the central position, and due to their elasticity do not interfere with its rotation around their axis.
How is an opaque protein form?
The matte white shade of the protein is evidence that carbon dioxide is in the egg in a large volume. A muddy color is obtained due to the fact that the egg is still fresh, and CO 2 did not have time to evaporate. In the eggs stored after the egg laying a long period, carbon dioxide safely left the shell through the pores.
Is it profitable to store eggs without packaging?
Given that the egg shell is permeated by millions of pores that contribute to the penetration of various smells and all sorts of bacteria, they recommend placing eggs into special trays. It is also desirable to avoid the neighborhood with the products that have a sharply expressed smell.
Eggs better place an acute or stupid side down?
Preferably put eggs with sharp end down. This is done so that the yolks occupy a central position. Also, such a position contributes to good ventilation: the eggs are better breathing in this position, since there is more pores in the blunt end, compared with acute.
What is the shelf life of eggs in the refrigerator?
Energic products can be stored in the refrigerator about 5 weeks from the date of their production. After 6 weeks of chilled storage, this product is not recommended to eat. The gifts of hens chuckles do not spoil quite a long time due to the fact that a protective film is formed on the surface of the shell.
And what does chicken egg size depend on?
The weight and size of eggs are due to a variety of factors. First of all, the age of chicken affects the mass: the younger female, the less small eggs she carries. As matters, their size becomes larger. If at the initial stage, the mass fluctuates in the range of 50 g, then to achieve a non-suck of one year, it increases approximately 65.
Why are eggs with two yolks?
Eggs with two yolks are formed in the case when 2 eggs in the organism of navels ripen simultaneously. As a rule, such a phenomenon takes place in very young females or one-year-old nurses. The largest percentage of "YIIC-twin eggs" falls on the first week of laying.
Previously, such products were considered unsuitable for use, however, given the large size of eggs, the mass of which reaches 80 g, zootechnics are specially engaged in the development of chicken breeds carrying such eggs.
The color of chicken eggs depends mainly from the breed of non-bias, and the intensity of the stuffing is affected by the content of carotenoid pigments. However, the flavoring and nutritional qualities of the color in no way affect.
Video - Myths about chicken eggs
According to nutritionists, color in this case does not matter And completely different factors affect nutritional value.
So where did the myth come from about the superiority of brown and beige eggs? And what do you really need to pay attention when choosing this product?
Let's try to figure out together.
The most common myths about chicken eggs and the cause of their occurrence
We are already accustomed that really high-quality food can not cost a penny. Therefore, the fact that today copies with a dark shell have a higher price than bright, not remaining without our attention.
It is better to pay more, but get a maximum benefit - we think we stretch in the store behind the tray of more expensive. And then proudly carry it home and we assure closest that brown eggs are certainly more useful than cheap white. Unfortunately, the stereotype: "more expensive, it means that it does not work here. The nutritional value of light and dark eggs is absolutely the same And the cost is not happening here. Why do we overpay?
Myth number 1. The higher the price, the more benefit
Immediately reassure that manufacturers do not try to deceive us, offering identical products at different prices.
The fact is that the breed of chickens carrying dark eggs are usually larger and use more feed. And since the content of such a bird costs more, we are forced to partially compensate the difference from their pocket. 
Myth number 2. Brown look more naturally, then they are environmentally friendly
This is a misconception from our childhood. In the villages used to serve the eggs of all shades of terracotta to the table, and the whites were the exception rather. Why?
The fact is that the color of the eggshell is directly related to the plumage of chicken navels. From the bird with a dark or pedestrian color, we will not get a white egg, and from brown - brown. In the villages, he used to prevailed chickens with golden-brown, gray, black or ripple plumage, which is associated with a feature of local breeds. Let's remember your childhood. How many did we see on the rustic streets of white chickens?
Dark-colored navigas found themselves in favor of a simple reason: they belong to meat-eggs, while a light bird belongs to the eggs, that is, the brewing broth do not prepare, and the roast will be so-so - without a bright taste. Naturally, in the home production it is better to have "universal" than "profile" chickens.
Here we left the memories that before the eggs were brown, very tasty and useful (our grandmothers often used them in medicinal purposes). 
Today in stores prevailing products of large poultry farms. White eggs in industrial trays subconsciously seem lower than quality. It is so, but the point is not in color, but in the lifestyle of churls. Rustic walked outdoors, ate natural food, moved a lot. And what do modern birds see, rarely leaving the limits of close cells? Whether they carry white or brown eggs, their products will not become more useful.
The same applies to the brightness of the rig. It differs in a more rich color in poultry, as opposed to the inhabitants of the poultry farms whose conditions of deals are far from natural.
Myth number 3. Brown eggs are thicker and stronger
In fact, this indicator depends on the age of chicken. What it is younger, the stronger will be the shell and the opposite.
The lifestyle of the bird, the state of her health and diet is no less important. No wonder as lure of farmers introduce various calcium additives: Ground seven, chalk, shrimp shelters, bone flour. These measures allow you to increase the density of the shell, make it more resistant to mechanical stress.
But the color here is not at all.
Let's summarize
To the question: what eggs are more useful, white or brown, without hesitation answer - home. The main thing - . 
As they:
- Eco-friendly. Chickens in small farms are on a free walking, feed on natural food, do not receive chemical stimulants and antibiotics.
- Possess a rich taste and pleasant aroma. Even the simplest dish from such a product will decorate the family table.
- Good for the health. Roosters live in domestic poultry houses, so almost all eggs fertilize and have a "right" hormonal background, which positively affects our body.
In order not to get caught on the fishing rod to the unclean on the hand of the sellers who offer under the guise of home shopping products with stamps should be addressed only to proven hostesses.
Distinguish factory eggs easily. They are the same in color and size, covered with smooth, as if polished shell. At home eggs, the surface is slightly rough, the shade and shape varies (after all, all the neutrals are different), and the bright spot is noticeably in the yolk - the future german.
Why are some eggs white, and other brown
We have already said that on the color of the shell affects the breed of smashing hens. Meat-egg varieties always have a dark plumage, eggs, light.
Accordingly, the first carry eggs with a brown shell of all shades: from almost beige to brick, and the second only with white.
Find out exactly what eggs will bear this or that chicken is easy. It is enough to look at the bridges of its ears. If they are bright almost white, it is just that will be the shell. If saturated red, eggs will be brown. 
Little biology
Persistent terracotta shades gives the protoporphyrin pigment shell. It is produced in the royal tissue of non-shells. The longer an egg is formed, the more intense of its painting, because the pigment is longer absorbed into the shell.
The percentage of protoporphyrin in cells is laid at the genetic level. therefore throughout the life of the chickens carry eggs of the same colorAnd its shades vary depending on the living conditions of the bird.
Note that brown and white is not the only option of the eggshell color.
- Araucan breed chickens, very popular in the USA and European countries, carry eggs of blue and turquoise shade. For that, they even called "Easter". The breed was called from the Indian tribe, which by long selection brought unique nurses, in the uterus of which contains a pigment biliverdin, giving blue and green.
- Non-masters of Maran are famous for their "products" with a deep chocolate tint. They are bred in the past century in France.
- The British Elevabar breed can fill our basket with eggs at once with three colors: turquoise, olive and creamy.
- Black chickens of an ancient Asian type of bluish - real exotic. They carry eggs that have not only a unique light mint color, but also the healing properties. The extractor of these poultry products can be heal from anorexia, hormonal disorders, cardiovascular diseases and problems with the immune system.
Regardless of the color, the eggs of all breeds are about the same nutritional value and taste. When buying it is worth paying attention not to the shade of the shell, but on its purity (there should not be the residues of chicken litter or sticking feathers) and the absence of a gloss. Moreover, important egg size, its weight and category.
The most useful are small in size, but tangible heavy specimens. They are carrying young chicken. The product with marking "1" is recognized as the most balanced in composition.
Now we will definitely choose only the best!
Surely, each of us saw chicken eggs with different colors on the shelves. Many people talk about product quality. But is it? In this article, let's try to figure out what the color of the eggs of eggs in chicken depends, and how it affects their quality.
Some believe that brown eggs are more natural. However, the color of this product is affected by a large number of factors. The color does not affect its taste. We will understand in more detail, from which the color of the shell depends.
Breed Kur.
Color uniforms for each separate breed of their own. For example, there are breeds with white plumage that have high productivity and the color of the shell from their masonry white. They are most often bred on an industrial scale. That is why on the shelves of the store or market there is a predominance of products with white color.
Farmers prefer to raise the chickens of a universal breed with high egg performance. As a rule, their color is brown, therefore, chicken eggs have an appropriate color. That is why they are considered more natural.
Environment
Temperature regime, stress, various diseases can affect the color of chicken eggs. The shade of brown can give the protoporphine pigment. This substance is much in a variety of vitamins, hemoglobin. The longer the fruit moves in the ovage, the richer is its shell. This is due to the long exposure to the pigment on the shell.
In addition, the color depends on the egg laying period. So, for example, the first eggs are slightly darker than the next. In the course of numerous studies, it was also established that the formation of their color is due to the presence of color pigment in the cells of the naval egg formation organ. In this regard, the color is laid in the early stages of the development of egg fruits.
White and brown: Is there any difference?
However, the difference of this product is only in color: one is white, others are brown. The presence of yolk, nutrients and other characteristics is absolutely identical, and it does not depend on different colors. In this case, the shell thickness is almost the same.
Sometimes it may differ, but this is not the effect of color, but the age of chicken. In young fearful, fruits will be with a tolstoy and strong shell, which cannot be said about older nurses. Still for strength can affect the amount of calcium, which is obtained by a bird from feed. As a rule, their fruits acquire a fragile structure in the spring, when the organism of the chicken is depleted after the winter.
Video represented by channel Why? The show will allow you to find out which factors have a direct impact on the shade of the chickens.
Given all these arguments, the question arises: from which the cost of different eggs is dependent, if they are identical in its characteristics. Why a product with brown shell is more expensive than with white? It is easy to explain: most often this is a marketing stroke and no more. However, it is worth noting that the chickens that give the eggs of brown, require more feed, respectively, their content is more expensive. It is this factor that affects the cost of brown eggs.
Masonry cream color of various shades are common, as a rule, chickens of the dark color, but in other indicators there are no differences in the remaining indicators.
Sometimes products of different color differ in taste. Why is this happening? First of all, I would like to note that it does not depend on how the egg shell is painted in what tone. The difference lies in the nutrition of chickens, as it affects the color and taste of the yolk. If non-bunches that postpone fruit with different colors of the shell will eat equally, their taste properties and yolk tone will be identical.
For some reason, many people believe that the color of the yolk is an indicator of naturalness and freshness of the product. But it is not. Pigments such as carotenoids affect the yolyral structure. They are contained in the feed of plant origin. So, for example, if corn or herbal flour is added to the neuter food, the yolk color will be very bright. In Lucerne less than this pigment, so its shade will be pale.
