Eggs are a popular food, due to its availability and ease of preparation. We buy them in the store by the piece, not by weight, in cooking recipes also indicate the right amount (except for rare recipes with a complex composition), therefore people rarely take an interest in the mass of this product. Meanwhile, this is an important indicator on which the category depends, and therefore the price of the goods.
How much does a chicken egg weigh
Such goods in stores are not sold by weight, because:
- Due to the high probability that they are infected with salmonella, this would have to open a department in which other products would not be sold, and the seller could not work in parallel in the neighboring department. This would lead to a significant increase in store expenses.
- Due to the fragility of a large number of manipulations with the product would increase its battle and the cost of the store.
However, the weight of this product is important for:
- Cooks - in some recipes the taste and quality of dishes depends on it.

Weight dependence on egg category
Chicken eggs are such varieties:
- Dietary - This is the most recent product that was demolished not more than 1 week ago, it is marked with the letter D in red.
- Dining rooms - a week later, the dietary product changes its grade to a table one, the marking should now contain the letter C in blue. Store them up to 3 months in the refrigerator and up to 25 days without it.
Important! When eggs are stored, the liquid evaporates, so they gradually become easier. The same product, going from the variety "Dietetic" to the variety "Dining" will have a lot less.
Depending on their weight, they are divided into the following categories:
- Higher - marked "B" next to the letters D or C.
- Selective - marked "O".
- The first - with the marking "1".
- The second - with the marking "2".
- The third - with the marking "3".

There are only 4 categories in the European Union:
- Very Large - marked "XL".
- Large - labeled L ".

- The highest category - from 75 g in shell, from 66 g without shell.
- Selective - from 65 g in the shell, from 56 g without it.
- The first - from 55 g in the shell, from 47 g without it.
- The second - from 45 g in the shell, from 38 g without it.

Raw eggs are a unique source of the most valuable set of useful components. Consider in more detail the benefits and harms of raw chicken and quail eggs.
How much does a shell weigh in one egg?

- Highest category - from 9 g.
- Choice - 7-9 g.
- The first - 6-8 g.
- The second - 5-7 g.
- Third - 4-5 g.
The color of the shell does not affect the taste, variety or category of the product, it depends on the breed of chicken.
Did you know? In the US, breeds of chickens were bred, which are carried by eggs with green, blue and yellow shells, while their composition remains the same.
If pieces of manure and feathers are stuck to the shell, this indicates non-compliance with the rules of hygiene on the farm. It is better not to buy this product, and if contamination is noticed at home, then thoroughly wash the purchase with running cold water before use.

The orange color of the yolk is important only for household products; on farms for this color chemicals are added to the feed.
