It is customary to sell valuable food products to the population individually, and not depending on weight. Immediately after the eggs are laid by the chickens, they are immediately sorted and divided into weight categories. The product is then labeled, packaged, and then sold to the public. You can find out how much one chicken egg weighs by the letters of the marking that is applied to the shell or packaging.
How much does it weigh
Categories and grades are determined depending on the freshness and size of the product.Based on freshness, they are divided into dietary and table. Table varieties are more often sold in stores.
If the marking contains the letter “D”, then these eggs are no more than three days old – this is a dietary variety. The storage period should not exceed 7 days - after this the spoilage process begins, which can lead to poisoning. This category is marked with the letter “C”.
Without shell
How much a standard testicle weighs without a shell is primarily of interest to women who watch their figure and adhere to a proper diet. Manufacturers do not need this information, since it does not affect the cost of the product.
The shell weighs not so little - 10 percent of the total weight. To find out the weight without shell, you need to look at the average on the label and subtract 10 percent from it.
Weight of shell, white and yolk
Protein takes up most of the animal product. The grams of yolk and white vary depending on the category and variety. You can determine the average weight of the white if you subtract 35 percent from the total weight without the shell - that’s how much the yolk weighs. Accordingly, the protein weighs 65 percent of the entire testicle without the membrane.
Raw and cooked
Many people are interested in whether the mass of an egg changes if it is hard-boiled. During the cooking process, they do not have the ability to absorb water, nor give up liquid or boil down. Therefore, the mass of the product remains unchanged, regardless - 1 piece. the product is cooked, or a dozen.
A slight decrease in mass occurs only during frying. At this time, the product loses its protective shell; when the shell is broken and frying begins, a natural loss of liquid occurs - approximately 10-15 percent of the total mass. Only in this case the weight becomes a little less.
How to find out the weight of an egg by marking
Each testicle undergoes careful selection and subsequent marking. First, the grade of one of the letters is indicated - “D” or “C”. If dietary varieties are not sold within a week, the label will be changed to the letter “C”. Next to the letter they put a number that indicates the category, and therefore the average mass - “from 0”, “from 1”, “from 2”.
The most common category is considered to be “from 1”. But the product is also chosen based on its intended purpose. So, in some culinary recipes the category “with 3” is often indicated, with a weight of 40 grams. The weight of a selected egg exceeds 70 grams, but it is also more expensive.
Does weight depend on the breed of laying hen?
There are meat and egg breeds of chickens. Naturally, egg-bearing breeds lay significantly larger eggs. Representatives of the egg breed, in turn, are divided into several varieties, which differ in weight.
Many small eggs have great nutritional value. For example, Pavlovskaya chickens lay small eggs - about 50 grams, they are classified in the second category. The size and weight of the product may also depend on the age of the hen. Young birds have smaller testicles, while adult hens lay larger ones. Also, the size of the product can be affected by housing conditions, climate and feeding of the bird, as well as even the time of year.
Egg weight in grams by category
The variety depends on the weight of the product. When determining a category, there are standard standards that manufacturers must adhere to.
Approximate weight depending on category and grade:
- “with 3” – weight from 35 to 45 grams;
- “from 2” – from 45 to 55 grams;
- “from 1” – from 55 to 65 grams;
- “from 0” (weight of a selected egg) – from 65 to 75 grams;
- "Higher category" – from 75 grams and above.
Why are eggs sold not by weight, but by piece?
Basically, food products are sold in stores by first weighing them per kilogram. So why are eggs sold individually or by the dozen? There are several reasons for this:
- They have a weak and fragile shell, so they must be stored separately from each other. Therefore, manufacturers make durable packaging where the eggs are isolated from each other. If a fragile product is weighed on scales, it will simply break frequently, and retail outlets will suffer serious losses.
- The product should not be kept open on the counter. There may be pathogens of salmonellosis on the shell, which can easily spread to neighboring goods; after sale, people may experience poisoning.
- During long-term storage, some of the moisture still evaporates through the shell. Well, if sales are carried out by weight, then with large volumes of products sellers will suffer financial losses.
Poultry eggs are a necessary product on every person’s table. Cooking is rarely complete without them. Using the labeling data, you can find out the approximate weight and how fresh the eggs are.
When purchasing, you should always be interested in the expiration date of the product. Otherwise, you can get seriously poisoned.
