Chicken Eggs

Permissible storage period

The period of storage of goods is the first thing on which we usually focus our attention when buying. Chicken eggs are no exception. Depending on the time passed after the demolition of the chicken, they are divided into two types: diet and dining.

Dietary “D”

Dietary items include specimens, the shelf life of which does not exceed 7 days, not counting the day of the chicken’s demolition. In this case, they should not be at minus temperature. Moreover, this species should have a condensed protein, an equally colored yolk, and also the height of the space occupied by air, not more than 4 mm. The shell of such testicles must be clean, a small presence of dots or strips on it is allowed.

Canteen “C”

It is customary to include tableware for specimens that are kept at the temperature of a dwelling no more than 25 days from the day of their sorting, not counting the day of their demolition, or stored in refrigerated chambers no longer than 90 days. Such a product has a movable yolk, a small protein density and a height of the space occupied by air of more than 4 mm, which, as a rule, ranges from 5 to 7 mm.

Categories of chicken eggs and their weight

So, we know what kinds of chicken eggs are and what is the difference. Now let’s try to understand their categories. The key criterion by which eggs are ranked in one category or another is their weight, therefore, according to modern GOSTs, there are 5 main categories.

 

The highest category (B)

This category includes specimens weighing 75 g or more. They are usually designated by the letter “B”.

Selected egg (O)

The products of this category have a slightly smaller size and weight – from 65 to 74.9 g. It is indicated on the shell or packing with the big letter “O”.

The first category (D1 or C1)

1 category is designated on the shell by the number “1” and has a weight from 55 to 64.9 g.

The second category (D2 or C2)

To 2 categories belong those eggs that have a weight from 45 to 54.9 g. Such products are usually designated by the number “2”.

The third category (D3 or C3)

3 category last. The weight of the specimens ranges from 35 to 44.9 g and is designated by the figure “3”, respectively.
