How many grams in a dozen eggs. How much does a chicken egg weigh: without shell, boiled and raw, the average weight of one yolk and protein

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.

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 on the shell or on the container. Size affects grade, and grade affects price.

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:

1. Recipes usually indicate C3 grade.
2. The color of the yolk depends on the diet of the chicken. Unscrupulous manufacturers add dyes to the feed to increase saturation.
3. 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.
4. 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.

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

The mass of cooked chicken eggs (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 mass is important in the poultry industry. This indicator is fundamental in determining the variety.

Why retailers don't sell eggs by weight:

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

All this increases the cost of the finished product.

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

• dietary- no more than 7 days have passed from the date of demolition, they are marked with the letter "D";
• canteens- more than 8 days have passed since the demolition, they are marked with the letter "C".

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

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

without shell

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

Weight of white and yolk

It is impossible to name the exact weight of protein and yolk. A lot depends on the product category.

A chicken egg is a valuable product that should be included in the menu of everyone who cares about its health and appearance. It contains all the nutrients necessary for a person, including protein, as well as vitamins and minerals. For those who often cook dishes using them or follow a proper nutrition system, it is very important to know how much a chicken egg weighs.

general information

Each of us, when buying a dozen of these delicious components of any diet menu, paid attention to the fact that each of them has different letters and numbers on the shell. It can be C, O, accompanied by a certain numbering. This alphanumeric combination is called marking. Its simplest type will contain at least two characters - for example, C1. There are also more complex variations of stamps, which indicate the manufacturer and other information. In order to easily and independently, without weights, determine the weight of a chicken egg, you should understand the markings and learn to understand it.

The first character indicated in the label will indicate the type of dietary product, then its category is already indicated - it can have an alphabetic or numeric designation. In this case, the scope and expiration date depend on the first part of the stamp. In accordance with this, two types of eggs are distinguished:

• D - dietary, which have a shelf life of not more than a week (7 days) from the moment the eggs are sorted at the poultry farm. If for a measured period of time they were not realized, then they become canteens;
• C - canteens that can be stored for up to 25 days.

In general, the dining room is no worse in quality than the dietary one. It's just that the second one will be fresher and will be on the store counter for a shorter period. Such components of the diet menu can be consumed both boiled, fried, and raw, used as a valuable ingredient in the confectionery business, they are suitable for feeding small children.

The mass of the egg, depending on whether it is table or dietary, depends slightly, but it is still worth remembering that during storage of the product for a long time moisture loss occurs due to the process of evaporation through the shell. That is why even eggs of the same category and the same size, but just laid by the hen, will be heavier than those that have been lying on the shelf in the supermarket for some time.

Minimum, average and maximum weight depending on the category

Also, the marking necessarily includes the designation of the category, of which there are only 5. Thanks to these “signs”, it will be possible to determine just what the size and average weight will be. These are 1 - the first, 2 - the second, 3 - the third, B - the highest and O - selective categories. Knowing how much one testicle of a certain type weighs, you can roughly determine its weight.

Thus, it turns out that the average weight is about 50-60 g. Due to the double norm of the yolk content, two-yolk ones weigh, as a rule, from 80 g.

In recipes, the smallest eggs of the 3rd category are always taken as the basis, the mass of which is about 40 g.

By the way, this method of marking is used only in Russia, and it is these values ​​​​of indicators that will be relevant in our country. Abroad, the marking will be completely different, and the average weight standards there are somewhat different from the usual ones. For example, in Europe, the letter designations will be like this - S, M, L, XL - and resemble clothing sizes. And the average weight indicators there vary from 53 to 73 g.

Weight without shell

Each egg has three components - a yolk, white and shell. The share of the last component is equal to 10-11.5% of the total weight. Knowing this, it is easy to calculate how much one egg, peeled from the shell, weighs. And it is important to calculate this indicator for those who eat strictly according to a certain program, and love to cook gourmet dishes according to exact recipes.

The mass of the shell does not depend on its color - it can have any color, and this will rather indicate the breed of the bird than weight.

At the same time, the shell should not be considered an absolutely useless part. It is perfect for use on the farm - it goes as a feed additive for chickens, it can be used to make an excellent fertilizer for flowers. And even children's crafts using crushed shell can decorate the house.

Raw and cooked

Eggs can be eaten in a variety of ways. At the same time, the boiled product is very popular, it is often included in the diet for every day of any person, and can also be used to prepare all kinds of dishes. And for those who strictly monitor their diet, it is especially important to calculate how much a boiled chicken egg weighs to make a menu.

Since the contents of the shell have nowhere to go during the cooking process, and no moisture loss is observed, it is safe to say that the boiled product will weigh as much as the raw one. In both cases, the shell is not taken into account. But after frying, its mass will decrease slightly.

Weight of yolk and white

Sometimes you need to know how much protein is contained in a chicken egg by mass, as well as how much yolk is in it. These indicators can be calculated by knowing the percentage of all components of the product. So, the protein contains about 55-58.5%, and the yolk - 30-35%. Examples can be found in the table.

Knowing how many grams of protein is in one chicken egg is especially important for those who take care of their health, adhere to the basics of proper nutrition, and take care of their figure. It is recommended for such people to eat only this part at all, separating the yolk from it.

Interestingly, it is the egg, despite its invaluable usefulness, that is considered a source of cholesterol. And most of this substance is concentrated in the yolk. Therefore, it is important to use chicken eggs with caution. And knowing the weight of the product that chicken gives will help control the amount of cholesterol.

Chicken eggs are a universal product that is indispensable in the kitchen of any housewife. Of these, you can easily and quickly prepare breakfast, they are boiled, fried, made from them snacks, salads, added to pastries. It's hard to imagine a kitchen without them. But if any complex dish is being prepared, with a large set of ingredients, where you need to know the mass of products used, then it would be useful to know how much a chicken egg weighs. So it will be much easier to figure out how much you need to add in the end of the product.

Finding out the mass of one chicken egg is not so difficult. To do this, first of all, when buying a product, you need to pay attention to the packaging. Usually it uses a special marking, which determines the category of the product and, accordingly, the mass. So, the following categories are distinguished:

1. The third category - by weight they reach about 40 grams and are considered the smallest. They are usually labeled C3.
2. The second category is slightly larger and their weight is approximately 45 to 55 grams. Marking is C2.
3. The weight range from 55 to 65 grams is the first category and is marked C1.
4. There is also a selective category, the weight of which can vary from 65 to 75 grams - referred to as C0;
5. Well, the largest category is the highest (B). Standardly weighs from 75 to 80 grams.

Interesting! Since the contents of the shell have nowhere to go during the cooking process, and no moisture loss is observed, it is safe to say how much the boiled egg weighs, the product will weigh the same as in the raw one. In both cases, the shell is not taken into account. Here's a fried egg. the mass will decrease slightly.

without shell

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:

• the shell weighs - 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.

Interesting fact! No matter how the egg is boiled into a soft bag in a steep one, it weighs as much as a raw egg.

Weight of white and yolk

A whole egg weighs 50 g. The yolk makes up 1/3 of the egg and weighs 17 g. The white makes up the remaining 2/3 of the egg and weighs approx. 33 g. And accordingly, 21 whole eggs \u003d 1 kg 36 proteins \u003d 1 kg 53 yolks \u003d 1 kg.

Important! It's talking about an average, standard egg (usually sold by the dozen in supermarkets). If you prefer to buy eggs at the market, then XXL eggs are often found there - they weigh more!

The average size, or rather weight, of a raw yolk is 25 grams, for the largest egg.

As scientific experiments show, the minimum mass of the yolk starts from 18 grams. At its highest potential, it can reach up to 27 grams, of course, this is for super-large eggs, which many consumers are afraid of, because I think that the chickens that carry them are stuffed with something.

A typical average chicken egg weighs only 60 grams, the weight of the yolk is 32-35% in the egg and this is about 21 grams for a raw yolk. The weight of the boiled yolk is similar, about 20 grams. We take the weight of one chicken egg as 100%, the weight of the shell is 12%, the weight of the protein is 56% and 32% is the weight of the yolk.

Accordingly, the larger the egg in size, the larger the yolk. In this case, there are double yolks.
