The weight of an egg without shell. The average weight of eggs

Buying eggs in grocery stores, people rarely look at their appearance. Usually this product is selected by size. Has anyone ever wondered what the weight of chicken eggs is and how it affects other indicators of this product?

Labeling Rules

An egg bought in a store, as a rule, has a special stamp that contains complete information about the purchased product. You only need to be able to read it correctly. Marking is usually done in two ways:

1) The stamp is applied separately to the shell of each egg.

2) If the product is sold in special closed containers, the information is indicated on the packaging. Usually this is a label that sticks in such a way that when opening the box you have to break it. This ensures that the packaging is not reused.

Most often, poultry farms try to label all their products without regard to the type of subsequent packaging. Thus, the company is trying to avoid possible misunderstandings and substitutions. Understanding the meaning of each symbol of the marking applied, any buyer can not only give a general description of the product, but also determine the weight of the eggs on the counter.

Buyer Information

The simplest marking stamp contains two characters. The first is the type of egg, and it is indicated by the letter of the Russian alphabet, and the second is its size, and it is indicated conditionally in numbers or letters. Now you need to understand how to determine the weight of all this symbolism. There are many eggs, and they are all different. You need to figure it out in order. The letter symbol in the stamp indicates the type of product. This is not just a conditional name. In accordance with it, the shelf life and scope of poultry products are established. Therefore, eggs are divided into the following types:

1. Dietary ("D"). They are usually stored for no more than 7 days. Moreover, the countdown does not come from the date of manufacture, but from the date of sorting. This must be considered when buying in a store.
2. Canteens ("C"). Their shelf life reaches 25 days.

From this we can conclude that the dietary egg differs from the table one not in some special qualities. It is just likely that it is fresher. This is an important indicator. It is even more important than the weight of chicken eggs or any other. Perhaps that is why diet eggs are used for baby food. They can safely be boiled softly or used in the confectionery industry, for example, for the preparation of creams.

Weight categories of eggs

In addition to species, eggs are also divided into categories. There are only five of them:

• first (1);
• second (2);
• third (3);
• selective (O);
• higher (B).

This indicator allows you to judge the size of the product. Therefore, knowing it, you can approximately determine the weight of 1 chicken egg. On average, it is about 50 grams. Data on the dependence of the type, category and weight of eggs can be summarized in a table.

Table of the dependence of the weight of chicken eggs on their type and category

Those who like to cook should know that when writing recipes, specialists usually conditionally use eggs of the third category with an estimated weight of 40 grams. When making a purchase in a store, you can check the correctness of the marking displayed using the control weights.

Egg parts

Any egg consists of three parts. The percentage of each of them in the product as a percentage is as follows:

• protein - 58.5%;
• yolk - 30% ;;
• shell - 11.5%.

These indicators are approximately the same for eggs of all types and categories. Based on their above values, you can easily calculate the weight of a chicken egg without shell. For example, if an C1 egg weighs 60 grams, then its shell, respectively, is 7 grams, the yolk is 20 grams, and the protein is 33 grams. Usually such an indicator is not necessary, but sometimes it is indicated in some measures tables. In addition, some confectionery enterprises use melange to produce their products. It is a mixture of yolks and proteins without eggshell. In this case, knowing the weight of a particular batch of eggs, you can calculate how much melange can be obtained from it. It is worth noting that the weight of the shell is absolutely independent of its color. Eggs can be white, beige, brown, and even olive. By this characteristic, it is rather possible to determine the breed of chicken that laid a particular egg.

Boiled product

Chicken eggs are usually eaten raw, boiled, and fried. Boiled products are more often used in the daily diet of any person. Boiled eggs are eaten just like that or used to prepare a wide variety of dishes: appetizers, salads and even soups. When compiling recipes, specialists usually use the number of eggs in pieces, but sometimes it is necessary to have an idea of ​​the ratio of the components of a complex dish in grams. This is where the need arises to know the weight of the boiled chicken egg. In this case, you should immediately refer to the above table. You just need to calculate the weight of the protein and the yolk without the outer shell. This will be the desired value. After all, the eggs are boiled in the shell, as in a confined space, so any material losses in this case are practically excluded.

Average value

Two different eggs of the same category and species may have different weights. This is provided by the current standard. But if we are talking about large batches, then the permissible deviations in grams are usually not taken into account. Only the average value is taken into account, that is, the average weight of the chicken egg. For example, a dietary egg of the second category should weigh from 45 to 55 grams. Therefore, the average weight of such eggs in a batch is considered equal to 50 grams. In practice, it turns out that way. There are both larger and smaller eggs. If you set a goal and weigh, for example, one hundred eggs of the same marking, and then divide the resulting value by the total number, then the result will be the weight of 1 egg, equal to the average value approved by GOST. To expand the range, some manufacturers give ordinary eggs additional properties: enrich them with selenium or iodine, achieve a bright yolk color. In any case, the average weight is determined based on the category and type of product manufactured.
