Eggs are one of the important sources of human food because they contain many vitamins and a high percentage of calcium, which plays a key role in the intensification of bone tissue and strengthens its cohesion. Commercial centers and supermarkets in large quantities, and many of them are outside the refrigerators, although when we buy eggs we put them in the refrigerator immediately, so what is the secret behind this?
According to a research study, the reason for the presence of eggs in commercial places and supermarkets outside refrigerators or coolers is that they have a thin membrane that isolates the whites of the shell and can damage this membrane if exposed to sudden changes in temperature, according to the Helsingin Sanomat newspaper. Emirati.
If eggs are kept in large refrigerators and delivered to stores using trucks and there they are kept in refrigerators, they will be exposed to temperature changes during the transportation and preservation process, which will change the egg membrane and thus make its consumption dangerous.
Because water may condense on the surface of the egg, which facilitates the formation of microorganisms that may penetrate the egg through the pores of the shell, and the white membrane prevents what is known as “salmonella” on the shell, which is produced by chicken droppings, from entering the egg.
The best way to preserve eggs depends on the prevailing time period. In the summer, it is preferable to put them in the refrigerator, because eggs may spoil quickly at a time when it needs low temperatures, but when the weather is cool or moderate, it can be kept outside the refrigerator, depending on the method You like it using eggs.
The egg shell is characterized by being porous, so if the eggs are left outside the refrigerator, the air will enter the egg white faster than if you leave it in the refrigerator. It is usually found on egg cartons.
The entry of air into the eggs will affect the texture of the white, meaning that the white color will not be the same degree of brightness and the yolk will not be as concentrated as it appears in the eggs that you put in the refrigerator.
