Egg yolk weight. Chicken egg

Every farmer who breeds poultry is interested in having chickens of high productivity. In this case, not only the number of eggs is important, but also their quality, for example, size. After all, fromhow much does the resulting chicken egg weigh, depends on which category it falls into and how much you can get for it. Even with a large number of eggs laid, the benefit will be small if they have a small mass. We will talk about how the product is sorted and labeled, as well as how much one egg weighs on average, in this article.

Before the layer product is sent to the store, it is sorted and labelled. This is done in order to make it easier for you and me to understand what is the mass of the egg and how long ago it was laid. Most often, you can find the marking with the letters "C" or "D", which are applied to the surface of the shell or on top of the package.

These letters are deciphered as follows:

D - dietary, as a rule, red marking. A fresh product that has lain from the moment of demolition no more than 7 days.
C - canteen, as a rule, blue marking. The name says that the product is more than 7 days old, and they are sold within 25 days.

Accordingly, an egg labeled "D" that is not sold within the period of its implementation receives the label "C". Knowing how much a chicken egg weighs, its variety is determined, which also has its own marking. To do this, next to the letter value, a number from one to three or the corresponding letter is placed, for example C1, D1, CO, SV, etc.

In order to understand this with a clear example, we have placed the data on varieties in the table below:

Category	Weight, gr	Average weight, gr
3	35-45	40
2	45-55	50
1	55-65	60
Oh (choice)	65-75	70
B (highest category)	75	80
double yolk	80	—

From the table it is clear that the weight of a chicken egg with a medium-sized shell is 60 gr. But in culinary recipes, the 3rd grade is most often used, the weight of 1 piece of which is 40 grams on average. A pack of 12 of category C2, which is the most common, weighs about 600-700 grams. And in a kilogram, depending on the variety, it can be from 12 to 25 pieces.

The standards of other countries may differ from ours. So, in the UK, products weighing 50-60 grams are considered average. And Australia recognizes them as very large, because for them the average category is only 43 grams.

without shell

If the farmer is usually interested in the total weight of the product, then the weight of one peeled egg is more important for the consumer. The weight of the hard shell, that is, the shell, is usually 10% by weight of the product. Therefore, it is not difficult to calculate the mass of an egg of any category without a shell.

We entered the finished data into the table:

Category	Shell, gr	Without shell, gr
3	5	35
2	6	44
1	7	53
O (Choice)	8	62
B (Highest)	9	70

The shell of this nutritious product is not as useless as it seems. It is an excellent source of calcium, so it is useful to use it as a dietary supplement. On the farm, it can be added to bird feed, and also find application in the garden: to fertilize the soil in your area.

Raw and boiled

Is the mass different? raw product and waren wow? This question is often asked by those who are on a diet and scrupulously count calories. Since the egg does not gain moisture during the cooking process and does not evaporate it, it weight remains unchanged. One has only to take into account that the values of the mass with a hard shell will be differentand without. Only this will be the difference in weight between boiled and cheese m product.

Breaking down the weight

Since there are several varieties of eggs, then mass of yolks and proteins they have different. Typically as a percentage white accounts for 55% of the total weight, and yolk a - 45%. Some are very afraid of the cholesterol contained in this product, and very much in vain. After all, only a third of it comes from food, and even this third contains cholesterol. yolk occupies a very small share. In addition, the yolk contains many vitamins, phospholipids and useful amino acids: lecithin and choline.

Weight of yolk and white

Now that the common myth has been dispelled, we suggest including healthy boiled, fried or any other form of eggs in your diet more often. And to find out how much protein and yolk are contained in products of different categories, we suggest that you familiarize yourself with the table below.

Category	Yolk, gr	Protein, gr
3	12	23
2	16	29
1	19	34
O (Choice)	22	40
B (Highest)	25	46

A very long time ago, a person domesticated a bird, learned to get highly nutritious eggs and dietary meat from it. Since then, fairy tales have been composed about laying hens, beliefs and rituals have been born. Here are some of the most interesting facts noted in the history of poultry farming:

one egg of a meat breed of chickens can reach a mass of 50 to 65 grams;
decorative breeds of some chickens are usually laid in medium or very small clutches. So, one egg of the Malaysian serama weighs no more than 10 grams, and in size it is five times smaller than that of a domestic chicken;
but one Cuban laying hen can boast of gigantic achievements in the literal sense. One specimen in her clutch weighed about 148 grams;
chicken from Papua New Guinea, on the contrary, was demolished by only 9 grams. The farmers, without hesitation, ate the curiosity;
in England, a case was recorded when as many as 5 yolks fell on one protein;
chicken eggs may differ in color: the color of the shell depends on the breed of the bird and the color of its plumage, and is completely unrelated to its diet. The taste and composition of the products are absolutely identical. Laying hens with white masonry shells are considered the most prolific, so their product can be found on store shelves most often;
another fact concerning the color of the shell was noted in America. So the farmers managed to breed a breed that can lay yellow, blue and green eggs.

Video "Categories and terms of storage of the product"

The EdaHTVTelevision channel in this video will tell you in detail about how long eggs can be stored, what useful substances they contain and how to understand their markings.

Healthy eating is very popular these days. A person can adhere to it for various purposes: someone needs to get rid of excess weight, someone just tries to keep themselves in shape, and some, on the contrary, strive to increase muscle mass. Chicken eggs are needed to achieve any of these goals. Protein deserves special attention. Everyone has heard that it is not recommended to abuse the yolk, due to the high content of cholesterol in it. With protein, the situation is different: you can eat it as much as you like, but you still need to know the measure. To do this, it is worth considering the calorie content of egg white and at least roughly guessing how many grams of protein are in one egg.

Egg white - muscle builder

Those people who are actively involved in bodybuilding and fitness pay great attention to muscle mass. To do this, the body must necessarily receive protein in the required amount, which is calculated individually.

There are a lot of foods high in these nutrients, but eggs are one of the leading places. To calculate how many grams of protein are in one egg, you need to know the approximate weight of the egg itself. Well, if available, then you can make the most accurate calculations. But if they are not there, then it is worth remembering that on average one egg weighs about 60 grams, of which 20 grams belongs to the yolk. But you should not assume that by consuming the remaining 20 or 30 grams, you can get the same amount of pure protein. It also contains water, therefore, in order to find out how many grams of protein are in one egg, we need to take into account the nutritional value per hundred grams of the product. So, one hundred grams of egg white contains 11 grams of protein, when calculated for 20-30 grams, you can get only 3-4 grams of pure protein in one egg.

Athletes know that about 30 grams of protein is absorbed by the body in one meal. Therefore, in order to get the rate necessary for stable muscle growth, it is worth eating 8 eggs - and only 1 yolk, and everything else is protein.

for low calorie diets

In addition to bodybuilders, who are closely watching egg white, many girls eat it. It is not so important for them to know how many grams of protein are in one egg, since they are guided by a low content of fats, calories and carbohydrates.

They are great for this type of diet, because they are a natural and healthy product, and also contain few calories.

The calorie content of egg white per 100 grams is no more than 48 kcal, and in the protein of one egg there are about 14 kcal.

This is very small, but eggs are a satisfying product, therefore, including them in the diet of low-calorie diets, you can get rid of the constant feeling of hunger without harming your figure.

To remember how many grams of protein are in one egg, as well as calculate its calorie content, you can use a special table.

It will help to avoid confusion and clearly calculate the individual daily requirement of egg-derived protein and the number of calories needed for each individual.

Chicken eggs are one of the consumed products in the food market. This product has many positive properties, both nutritional and cosmetic. Often it is used by summer residents and many others. The egg has many characteristics that can be listed without hesitation. But every second person still thinks about one indicator - weight.

For unknown reasons, few people ask the question "how much does a chicken egg weigh?" This is interesting and useful information. It depends on the weight to which category the result of chicken efforts will be assigned.

Chicken eggs are divided into table and diet.

All eggs can be divided into two groups:

Dietary.
Canteens.

The first group includes fresh eggs that are stored for no more than seven days. The second group - the dining room - includes eggs with a shelf life of up to 25 days at room temperature and 90 in the refrigerator.

Eggs are also divided into smaller categories:

higher;
selective;
first category;
second category;
third category.

There are several categories of chicken eggs.

Higher - 75 or more.
Choice - 65-74.
The first is 55-64.
The second is 45-54.
The third is 35-45.

Depending on whether the egg belongs to a table or dietary egg, a seal is made with the initial letters of the category and group: CB, DV, etc.

Interesting: in a famous book with world records there are several entries regarding eggs: the largest recorded size is 136 grams, and the smallest is just under 10 grams.

The average weight of a chicken egg of the first category is 55-64 grams.

Usually the cheapest small eggs are laid by young hens. Accordingly, large ones, which primarily attract attention, are more mature individuals.

If we take the average weight of all eggs, then we can say with confidence that one average egg will weigh from 40 to 60 grams. This is one of the most common types and recommended in culinary recipes.

Well, what will the experts answer in this matter, if you ask them: how much will an egg weigh if it is without a shell? It is possible that someone will be confused, someone will pretend that they are not talking to him, but the true gurus of the egg business will answer.

Egg weight without shell is important in making melange.

Their answer will be from one numeral: 55 grams. But this figure is approximate, since each egg has its own weight, which can fluctuate even within the same category. Egg weight without shell is important for confectioners who are engaged in the manufacture of melange.

Reference. Melange is protein and yolk dried using a special technology.

To determine the weight, experts use a percentage that helps them accurately calculate the required value.

Converting to a percentage, we get the following result:

shell - 12%;
yolk - 32%;
protein - 56%.

A percentage is used to determine the weight of a raw egg.

By removing the shell, we get 88% of the total mass of the egg, regardless of the marking.

How much does a raw egg weigh

Interestingly, a raw egg may differ from the declared weight. When buying eggs by marking, its weight is approximately known. But, having come home, you can find that the weight of a dozen eggs is less than stated.

The first thing that comes to mind is the idea of cheating. But it's not. The fact is that when lying through the shell, moisture gradually evaporates, and, accordingly, the weight of a raw egg can fluctuate not only by category, but also by freshness.

Important. The fresher the egg, the more it weighs.

Another interesting fact is that during cooking, the weight of the eggs remains unchanged.

A boiled egg does not change its mass.

This happens for a very simple reason: the shell is a protective shell that does not let moisture in and out, leaving all the components in place. And for this reason, a boiled egg in weight is the same as a raw one.

But a fried egg will weigh less. With this method of cooking, the moisture evaporates, and the weight becomes less. It is also worth considering the very 12% of the shell that is removed during the preparation of products for fried eggs.

If you break an egg into components: protein, yolk, shell, it turns out that the most significant part is the protein, and the lightest is the shell. No wonder the testicle can be damaged so easily.

The heaviest part of an egg is the protein, and the lightest part is the shell.

If we translate into numbers, then on average we get the following result:

Protein - 33 grams.
Yolk - 22 grams.
Shell - 7 grams.

Abroad, they say, life is different. Maybe, in general, it does not differ from the domestic one, but there are many differences in the details. This also applies to marking eggs. Interestingly, imported eggs are divided by weight into other groups than ours: from the smallest at 30 grams to 73 grams.

On imported packages with eggs, in addition to markings indicating weight and size, you can also find other marks. The “eco” badge is placed on the boxes containing products from chickens that have freedom of movement. For many, this fact is important.

Imported eggs are divided into other groups by weight: from the smallest at 30 grams to 73 grams.

The eggs of European laying hens are divided by size, and according to the size, they are stamped with a certain marking:

Small (S) - 40-53 grams.
Medium (M) - 53.90-63.
Large (L) - 63.90-73.
Very large (VL) - 73 and up.

Reference. Eggs of European quality, unlike ours, are divided into 4 groups: 2 and 3 categories are combined into one.

In addition, each egg has a number that can be used to determine in which country the hens tried.

European laying eggs are divided by size: S, M, L, VL.

Usually eggs are brought from only 4 countries:

Belgium - 1.
Germany - 2.
France - 3.
Holland - 6.

Here are two reasons why eggs are sold individually:

Fragility. If you think logically, then the piece-by-piece form of sale is not only convenient for both the seller and the buyer, but also safe. It is enough to remember what percentage the shell is of the total mass of the egg and it becomes clear that unnecessary manipulations can lead to disastrous results.
Percentage ratio. When lying for a long time, the thin shell begins to pass moisture through itself and the egg decreases in weight. Considering this factor, selling by weight would become unprofitable.

It is unprofitable to sell eggs by weight: over time, the egg loses moisture and, accordingly, mass.

Here are a few facts you might not know:

Eggs may not be labeled if they are packaged in a box.
In recipes, the calculation usually goes for one egg per forty grams.
Diet eggs have a red stamp, canteen eggs have a blue stamp.
On the modern market, you can find both simple chicken eggs and enriched with vitamins. These are sold marked "fitness".
Adhering feathers and manure on the shell do not indicate the environmental friendliness of the eggs, but the lack of hygiene in the poultry farm
Each country has its own idea of large and small eggs.

A dirty chicken egg shell indicates unsanitary conditions in a poultry farm.

The weight of eggs helps not only to save money, but also to calculate the correct number of them for preparing a particular dish. When buying eggs, it is important to pay attention to the absence of cracks, dirt and other adverse factors that may indicate unsanitary conditions, and therefore likely infections.

The exact parameters of a chicken egg are not specified anywhere. We will figure out how much one egg weighs and what are the weight criteria for each category.

Many people read the calorie content of foods, but they don’t think about the parameters. We will calculate the exact weight of this product according to the categories, and also indicate how many grams of protein and yolk are contained. Such information can be useful to cooks or people leading a healthy lifestyle who count the number of calories eaten and the weight of the food consumed.

Marking

According to the law of the Russian Federation, all eggs must be labeled according to category. Enrollment in one of the groups occurs during sorting right at the poultry farm - there they are examined, weighed and packaged.

There are five categories in total:

third;
second;
first;
selected;
higher.

Also, when numbering, the letters "C" and "D" are used. The first designation implies a table egg - such a product can remain fresh longer than the others, the letter “D” is applied to dietary ones, they must be consumed in the first week after demolition. Otherwise, such an egg will become an ordinary table egg, losing all the dietary properties of the yolk and protein.

There is a marking with a combination of letters and numbers, for example, c1 or c0. This means the category awarded and belonging to the dining or dietary species.

The weight

The second in the shell - from 45 to 55 g, without the shell no more than 36 grams, the yolk - from 14 to 16, the protein - 25-30.

In the first, the weight of a chicken egg ranges from 55 to 65 grams, and without a protective shell - from 50 to 58 g. The yolk has a weight of 18-24, protein - 30-33.

In the highest, a chicken egg weighs from 75 g or more. Such testicles are considered the largest. The weight of an egg of the highest category without a shell is 67 grams, of which 26-28 yolks and 39-42 proteins.

On average, the weight of one ordinary testicle is equal to 40-50 grams - they are attributed to the third or second category.

Such testicles are in great demand among buyers, so they are mainly presented in supermarkets. Also, the third category is the most common in culinary business - it is used for baking, salads, cocktails, as an ingredient in hot and cold dishes, as an ingredient for an independent dish (scrambled eggs).

Weight of packing

Basically, manufacturers make packages of 10 or 15 pieces, occasionally there are extended versions with 25 or 40 units of goods. Therefore, the average weight of the package is 350-450 g, if we consider the third category and the minimum number of eggs in the package. For the second category, from 450 to 550 g is considered normal, for the first - 550-670, for the selective and highest - at least 650.

However, the weight of the package can vary based on expiration date, so if you come across a dozen testicles in the hypermarket that weigh less than 350 grams, then most likely they have been on the counter for more than one week. It is not recommended to take such a product, it may be unsafe for health.

When choosing a product, also look at the appearance of the product: if they are of different sizes in the package, then several categories can be mixed into one. Thus, poultry farms are trying to sell a product from the third category under the guise of the highest or selective.

The parameters of this product also depend on the laying hen itself - its living conditions, feed, bird health. Some birds carry eggs much more than others: for example, the weight of the largest egg exceeds 140 grams. And there are also birds that produce small testicles: for example, the weight of the smallest is equal to 10 g.

The weight of chicken eggs clearly reflects the health of the laying hen, the nutritional value of the product itself. The mass of the product depends on the age of the chicken, its breed and health. This indicator is very important for farmers who sell eggs.

According to the labeling table, the average weight of 1 chicken egg is 60 g. This is the CO / DO category.

Payload

Useful weight is the weight of chicken eggs without shells. The egg consists of the shell, protein and yolk. The volume of the yolk is approximately 34% of the total, protein - 55%, shell - 11%.

The weight of an average chicken egg in grams in parts:

General - 60;
Yolk - 20.4;
Protein - 33;
Shell - 6.6.

If you need to determine the useful mass, but there were no scales at hand, it can be calculated.

For each individual category, it is different:

CB - 71.2 g;
CO - 62.3 g;
C1 - 53.4 g;
C2 - 44.5 g;
C3 - 35.6 g.

Weight of cooked product

During heat treatment, products lose weight. But a hard-boiled or soft-boiled egg will remain the same as a raw one.

Marking and weight

The marking consists of a letter and a number, where the letter is the category and the number is the grade. It is applied directly to the shell or to the container. Size affects grade, and grade affects price.

Category	Variety	Sign	Weight, g
Canteen	Higher	SW	75–80
	selective	SO	65–75
	First	C1	55–65
	Second	C2	45–55
	The third	C3	35–45
dietary	Higher	DV	75–80
	selective	BEFORE	65–75
	First	C1	55–65
	Second	C2	45–55
	The third	C3	35–45

Diet is stored up to 7 days. If it is not sold within its expiration date, then it goes into the canteen category.

At room temperature and air humidity of 85%, dietary eggs are stored for up to 25 days; in the refrigerator - up to 90 days. The countdown is from the date of sorting, not manufacturing.

Imported products

The designation of foreign products differs from that adopted in the CIS countries. European weight standards are shifted down.

Table of symbols for imported eggs.

The stamp contains the country code of the manufacturer. Germany - 2, for Holland - 6.

This is indicated when labeling:

0 - agricultural production;
1 - free content;
2 - the bird is kept on a perch;
3 - the chicken lives in a cage.

If the green badge is present, then the hen's diet did not contain genetically modified cereals. She was kept in an open pasture, fed on food rich in chlorophyll.

Strict restrictions are imposed on the use of various veterinary drugs: supplements, antibiotics, growth stimulants.

On a note

Some useful facts:

Recipes usually indicate C3 grade.
The color of the yolk depends on the diet of the chicken. Unscrupulous manufacturers add dyes to the feed to increase saturation.
The older and larger the chicken, the larger the product. There is also a dependence on the breed. Meat or decorative breed will not live up to expectations.
The shell is impervious to bacteria and pathogens. It has a porous structure and allows air, moisture and ultraviolet rays to pass through. Its color does not affect the nutritional value and the set of trace elements.

Piece sales

One careless movement and instead of a neat testicle, an unappetizing mixture is obtained. Therefore, the less manipulations are carried out, the less losses the manufacturer will suffer.

It is not economically viable to sell in kilograms, since the price will have to include marriage and weight loss during long-term storage. This will lead to a decrease in demand.

Important information

What you should pay attention to:

Cracked testicles should not be eaten. Through damage to the protective cover, the causative agent of salmonellosis, the Salmonella bacterium, can get there;
Dirt, droppings, a sticky feather testify not to “organism”, but to non-compliance with sanitary standards by the workers of the poultry farm;
Storage: in a cold damp place, isolating from foods with a strong odor, raw meat, fish;
The manufacturer may put the wrong stamp, so you need to open an opaque container.
