It is commonplace that when buying eggs, the product is in the supermarket shelves, but when they come home, they are stored automatically inside the refrigerator. Many believe that there may be contradictory activities, as there is a scientific explanation.
SAIA Food and Water Safety Adviser Luis Riera explained that "a cuticle, that is, a thin layer that wraps under the egg shell, can explode with a sudden change in temperature". Sulfur can be a great risk to your health, because the layer is the one that protects you balls salmonella, which may contain it in its shell.
"If we go out and put the eggs in and out of the refrigerator, then the natural protection could be lost," he said. And he pointed out that cold and heat contraction or expansion would outweigh the cut, so the ideal thing is not to cool balls before they reach our refrigerators.
Riera said that "the egg, although it is intact, is quite sterile. No matter, you keep it cold or hot, as long as it has not lasted more than 28 days, which is about to expire."
Because there are people who usually wash the eggs before they are stored, Riera pointed out that it is a mistake because water pressure can break the nail tape. "Before you use them, they can be washed, but just before consumption, because salmonella does not have time to reach."
What's the reason why balls On the inside of the refrigerator, the expert pointed out that "the air lasts longer and the egg is concentrated when it is cooked or baked". In other words, the refrigerator allows the egg to be stored in thicker and more concentrated yolk. However, if you want to hit the egg, "no matter whether it is fresh or less".
Riera, on the other hand, pointed out that there is a trick to know if the egg is fresh or not. It consists of "putting it in a glass of water, and if it is absorbed, it means it has been a while, it has little air and is fresh." Otherwise, if it floats, it means that it is an old egg because a lot of air has come to it.
Nasty surprise: he prepared a fried egg and found … "umbilical"!
