An egg that sinks at the bottom of a glass of cold water is cool, while what swims is old.
Experts warn, however, that the test reveals only the age of the egg, and security is determined by the smell, appearance and deadline.
When an egg box has been in the refrigerator for a very long time or do not know that when bought, many people use the old trick – place the egg in a glass of water and see if it sinks or floats. The test really shows something, but less than usual.
Why an old egg swims?
According to the US Department of Agriculture ( U ndo SDA has no air room. It forms at the widest point as the egg cools. In time, moisture and carbon dioxide evaporate through small harbors into the shell, more air enters, and the room grows. The bigger the egg, the easier it swims.
That is why an egg that sinks into a glass of cold water and lies next to the bottom is fresh. If you stay up at the end, it’s older, and if it swims on the surface, its air room has grown significantly.
A swimming egg is not necessarily rotten
U n The SDA claims that a swimming egg is of lower quality, but it can be fully safe to eat. They recommend that such an egg be divided into a special vessel and checked.
A rotten egg smells unpleasant, both alive and cooked. A pink or pearl white egg is also a sign of decay. A vague white egg, on the other hand, means that the egg is very fresh, while a bright white egg means it is getting old.
United Kingdom Food Standards Agency ( The FSA does not recommend the water test at all. Narriman Looch, who runs the food-transmitted disease department at the FSA, told the consumer group in the United Kingdom, that the test shows the age of the egg, not its security. She says she cannot find out what bacteria have developed inside.
Even the smell alone isn’t enough, does Which warn?: An old egg that smells normal can still contain dangerous bacteria.
Save and Save Time
The eggs have a better expiration date before no more than 28 days of their deployment, according to the Scottish Food Standards Scotland Food Agency. According to the FSA, the eggs are still safe for several days after that date, but only if both white and yellow are well cooked.
Eggs with split or slippery shell must be thrown away because bacteria can enter. The USDA recommends keeping the eggs in the original box in the coldest part of the refrigerator, not at the door. They should not be washed before storage because water can absorb bacteria through the harbors. Eggs from the refrigerator should not stay at an environment temperature for more than two hours.
However, older eggs have an advantage. As the egg grows old, the egg’s white becomes more juicy and clings less closely to the membrane under the shell, so that old boiled eggs are more easily developed, according to the USDA.
