Why is it important to know the weight of a chicken egg? Their weight categories. Differences between Russian and European categories. Why do they differ in weight?

Not all buyers think about the size and weight of the eggs they purchase. If we need a couple for a recipe, we just grab them from the refrigerator. In some cases, for successful preparation of a dish, for example, for baking, it is necessary to take into account how many grams are in one egg. For culinary purposes, special tables have been developed for converting the number of eggs of one size into the number of another size.

Also, when preparing dishes, it is important to pay attention not only to the weight of the chicken egg, but also to the number of yolks in it. After all, sometimes you come across options with two yolks. Manufacturers have learned to manage the reproductive cycles of chickens so that they lay just such eggs. Replacing regular product on one with two yolks, you risk getting a non-standard result.

Weight categories

For the sake of objectivity and convenience, eggs are divided into categories not by size, but by weight. When you purchase a package, do not think that all of them are the same. They are formed not according to the individual weight of 1 egg, but according to their average weight in the package. This is due to limitations in the technology for automatically sorting eggs by size. In one package they may look different in size, but their weight usually fluctuates within a certain range, regulated by documentation.

• C3 - third, weight less than 45 grams;
• C2 - second, 45-55 grams;
• C1 - first, 55-65 grams;
• O - selected, 65-75 grams;
• B - highest category, more than 75 grams.

If we accept average weight eggs equal to 50 grams, then its weight without shell will be 5 less. The average weight of an egg white is 27 grams, and the yolk is about 18. During cooking, the weight does not change significantly, as does the ratio between yolk and white.

You can see the imported product in the store. As an approximate analogue, you can use the following correspondences between Russian and European markings:

• S (Small) correspond to Russian C3 and C2;
• M - C1;
• L - O;
• XL - B.

If you use this product to prepare basic dishes (omelet, scrambled eggs), then the weight of one chicken egg will not matter much.

In most baking recipes, the ratio between dry weight and dry weight is important. liquid ingredients and the added volume of yolks and whites. Most of them also use large eggs(that is, the first category).

Volume characteristics of one large egg:

• 3 tablespoons ( 45 ml);
• 1 egg white= 2 tablespoons ( 30 ml);
• 1 egg yolk= 1 tablespoon ( 15 ml).

Reason for weight difference

As chickens grow older, they begin to lay larger and larger eggs. Weight: 1 pc. Chicken eggs are influenced by the breed of laying hen, seasonality, feed composition, lighting conditions and a number of other factors. Agricultural producers use these methods to produce larger specimens.

Among those on sale, the smallest eggs are quail eggs, weighing only 10-12 grams, and the largest - ostrich ( about 1.5 kilograms).

Eggs are often used as an independent product (boiled, scrambled), but they are also often components of many culinary dishes. Few people realize how much a chicken egg weighs.

Knowing the answer to this question is important because it often becomes necessary to observe the amount of certain ingredients in preparing dishes so as not to spoil them, and also to more accurately calculate the number of calories when cooking dietary nutrition. About weight different types eggs can be found just below. But first, a little about the egg itself.

Egg: nutritional value

Any egg consists of two parts located in the shell: the white and the yolk. The yolk itself contains proteins, fats and cholesterol. Protein contains 90% water, the remaining 10% proteins. Mass ratio of three components eggs (shell, white and yolk) is respectively about 12:56:32. It turns out that the protein mass is the largest. We will find out how much 1 chicken egg weighs in general later.

Egg is one of the most widely used food products among people. It should be noted that any bird eggs can be eaten by humans. They are edible even in certain reptiles, such as turtles.

Chemical properties of eggs

The composition of bird eggs differs depending on the breed, type, age, feeding conditions and maintenance.

One egg (chicken) contains the following percentages of certain elements: proteins - approximately 12.57; fat -12.02; carbohydrates - 0.67; minerals- 1.07 and water - 73.67. At the same time, the calorie content of 100 grams of egg mass is approximately 158 kilocalories.

The largest egg in the world was recorded in the Republic of Cuba. Its weight was 148 grams. And the weight of the tiniest egg laid by a chicken in Papua New Guinea was only 9.7 grams.

The weight of eggs, according to Russian legislation, is divided into groups. Because this question is also important in sales production of this product in markets and shops.

The weight depends on the established categories of eggs:

3rd category is assigned to eggs weighing from 35 to 44.9 g;
Eggs of category 2 have a mass of 45-54.9 g;
Category 1 - 55-64.9 g;
Select eggs (marked “O”) weigh from 65 to 74.9 g;
Highest category (marked “B”) - 75 g or more;

The average eggs collected on your own farm are approximately 40-65 grams.

What's the result? How much does a chicken egg weigh? Most often, the average weight of an egg is taken to be 60 grams. This weight represents the mass of a standard chicken egg.

How many eggs are in one kilogram?

A very interesting question. Knowing how much one chicken egg weighs, you can determine the number of testicles in 1 kilogram. It turns out that one kilogram can contain from 15 to 25 medium-sized eggs, depending on the categories. Accordingly, 10 chicken eggs weigh approximately 400-650 grams.

The above data applies to eggs with shells. You can consider the data without taking into account the weight of the shell.

How much does a chicken egg weigh without a shell?

Without the shell, a selected egg weighs 59-68 grams (36-41 grams of white, 23-26 grams of yolk).

All this data is needed when it becomes necessary to determine how much boiled food weighs. egg(purified). This is necessary in cases where complex recipes are calculated in grams, not in pieces. You just need to look at the weight without shell using the above data.

To easily determine the weight of eggs, you should buy the product according to the factory category labeling. Usually in cooking the third category is used, weighing on average 40 grams.

The raw weight of a chicken egg is important in determining the cost of the product. It depends on the breed of bird, the conditions of its keeping and feeding, the season, etc.

The weight of a cooked chicken egg (boiled, fried, etc.) depends on the type of processing.

Average weight of one chicken egg

According to statistics, the average chicken egg weighs 50–55 g.

Its size is influenced by a number of factors:

• age;
• breed;
• conditions of detention;
• quality and frequency of feeding, etc.

Testicular weight is important in poultry farming. This indicator is fundamental in determining the variety.

Why in retail trade Eggs are not sold by weight:

1. The egg loses weight over time as the liquid through the shell evaporates.
2. The fragility of the product implies the presence of a separate worker weighing the product.
3. Current sanitary standards require a separate room for product scales.

All this increases the cost of the finished product.

According to the degree of freshness, eggs are divided into:

• dietary– no more than 7 days have passed since the day of demolition, marked with the letter “D”;
• canteens– more than 8 days have passed since the demolition, are marked with the letter “C”.

Important! The table variety is stored at room temperature 25 days from the date of demolition, in the refrigerator - 90 days.

Eggs are usually sold in packs of 12, but the quantity may be smaller (6 or 10).

Without shell

The weight of the shell is 10% of the weight of the entire egg, therefore, by looking at the labeling in the store, you can use simple arithmetic calculations to determine the weight of the product without the shell.

Weight of white and yolk

It is impossible to name the exact weight of the white and yolk. Much depends on the product category.

The weight of chicken eggs clearly reflects the health of the laying hen, nutritional value the product itself. The weight of the product depends on the age of the chicken, its breed and health status. 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.

Useful weight

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

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 useful mass, but there were no scales at hand, it can be calculated.

For each separate category it is different:

• DM - 71.2 g;
• CO – 62.3 g;
• C1 – 53.4 g;
• C2 – 44.5 g;
• C3 – 35.6 g.

Weight of cooked product

At 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. Apply directly to the shell or container. Size affects the grade, and grade affects the price.

Category	Variety	Sign	Weight, g
Dining room	Higher	NE	75–80
	Selected	CO	65–75
	First	C1	55–65
	Second	C2	45–55
	Third	C3	35–45
Dietary	Higher	Far East	75–80
	Selected	BEFORE	65–75
	First	C1	55–65
	Second	C2	45–55
	Third	C3	35–45

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

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

Imported products

Designation foreign products differs from what is customary in the CIS countries. European weight standards have been shifted downward.

Table of designations for imported eggs.

The stamp contains the manufacturer's country code. Germany – 2, for Holland – 6.

This is indicated when marking:

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

If the eco-friendly icon is present, then the laying hen's diet did not contain genetically modified grains. She was kept on open pasture and fed chlorophyll-rich feed.

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

On a note

Some useful facts:

1. Recipes usually indicate the C3 grade.
2. The color of the yolk depends on the chicken's diet. Unscrupulous manufacturers add dyes to food to increase saturation.
3. The older and larger the chicken, the larger the product. There is also a dependence on the breed. A meat or ornamental breed will not live up to expectations.
4. The shell is impenetrable to bacteria and pathogenic microorganisms. It has a porous structure and allows air, moisture and ultra-violet rays. Its color does not affect nutritional value and a set of microelements.

Piece sales

One careless move and instead of a neat egg you get an unappetizing mixture. Therefore, the fewer manipulations are performed, the less losses the manufacturer will bear.

Selling in kilograms is not economically profitable, since the price will have to include defects 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 enter there;
• Dirt, droppings, stuck feathers do not indicate “organicity”, but non-compliance sanitary standards poultry farm workers;
• Storage: in a cool, damp place, away from foods with strong odors, raw meat, fish;
• The manufacturer may put the wrong stamp, so you need to open the opaque container.

Kira Stoletova

If you are going to raise chickens not only to please your own taste buds, but also for the sake of replenishing your wallet, you should find out how much a chicken egg weighs without the shell and with it, because the price of the product and the category to which it belongs are directly dependent on its size.

Meaning of marking

The egg must be marked before being sent to the store. The marking can be seen directly on the shell or on the packaging; it consists of 2 characters. The first indicates the freshness of the product, the second - the category and approximate weight.

1. C means "table", i.e. with a period of more than 7 days from the date of demolition.
2. D - “dietary”, or, in other words, the freshest product “just” from the chicken. After 7 days it becomes a “canteen”.

The category is designated by the numbers: 1, 2 and 3, or by the letters O and B. In the European equivalent, the signs will look like this: M (1), S (2, 3), L (O) and XL (B). O means “selected”, and B means the highest category. The average weight of each category is shown in the table:

If we talk about standard products, one glance at their labeling should tell about its characteristics. In regular stores, everyone has most likely seen (and sees) eggs marked c1 or c2 (that is, a table egg of category 1 or 2).

Weight without shell

Shells are rarely used in cooking, so it is quite natural that buyers are interested in the question, how much do the yolks and whites weigh without shells in one individual chicken egg? The average weight of the shell is 10% of the total weight of the raw egg.

The shells are not as useless as they seem (remember this the next time you throw them away). Shells are a source of calcium, beneficial for health and growth. poultry. Resourceful owners, instead of buying additives in pet stores, add crushed shells to their feathered pets' food. The shell is used in other areas of life, for example, it is used to make plant food and cosmetics.

How much does the yolk weigh and how much does the white weigh?

The weight of the white in one egg is 55% of the mass, and the yolk is 35%. As you can see, the bulk of the mass is protein, which in turn consists of 90% water. Water gradually evaporates during long-term storage, and consequently weight decreases. This is about the question of why the mass in a chicken egg bought in a store is less than it should be. Weight loss is inevitable, so don't consider it a scam. Let's look at how much the yolk and white weigh in the table:

How much does a chicken egg weigh?

Eggs for weight gain. My recipe.

The chickens began to lay large eggs.

Some interesting facts to note

1. The weight of the raw and hard-boiled product remains almost the same, if you exclude the weight of the shell.
2. Average weight is still average weight. It happens that chickens lay “unformatted” eggs. Sometimes paper newspapers and online publications begin to literally be full of reports that someone’s chicken has laid an egg weighing only 5 g (this is less than a quail!) and news about the appearance of an egg weighing 200 g or more. Non-format sizes in our table, of course, are not included, but poultry owners should be aware of such cases (and find in advance the addresses and telephone numbers of people who are involved in entering new records into the Guinness Book of Records).
3. By the way, now the proverb “a black hen lays a white egg” has become somewhat irrelevant. Now it can lay not a white, but a blue or greenish egg. The color of the shell depends on the breed, but mineral composition“multi-colored” products are the same as regular white ones.
4. Cholesterol - a myth or not a myth? Some diet advocates fear the cholesterol in yolks. It really is there, but it is not as much as the myths say. In other words, it can be eaten by those who are on diets, but, of course, in limited quantities. It is believed that you can afford an omelet with 1-3 yolks or the same amount of boiled products per day.

The benefits of eggs are undeniable, just read the list useful substances which they contain, so that you can be sure of this. So eat them and choose the best quality products, since now it’s clear how to decipher the incomprehensible signs on the shell. Now you know how much an egg weighs, the benefits and harms of this product.
