Eating stale eggs is fraught with unpleasant consequences for the body, sometimes leading to hospitalization. That is why it is worth knowing about simple ways to test eggs for freshness. There are several of them, all of them are quite simple.
Water test
This test requires a deep bowl, water, and one egg. To find out if it is fresh or not, you need to fill a bowl with water, carefully lower an egg into it. The fresh one will immediately sink to the bottom and lie on its side. This is because the air cells in the egg are extremely small.
An egg that is not the first freshness will begin to float or "stand" on the bottom of the bowl in an upright position. The wider side of the egg will be closer to the surface, the narrower - to the bottom.
Eggs that are completely floating in the water and not touching the bottom of the bowl can be discarded immediately as they are more likely to be spoiled.
Yolk type check
In this case, you need a flat plate. The egg needs to be broken and looked at. The yolk of a fresh egg is usually round and compact in appearance. It is located in the middle of the egg, rather high. The surrounding protein should be thick enough and close to the yolk.
A less fresh egg is characterized by a spilled flat yolk and a thin liquid white that spills over the entire plate.
Light test
You can also evaluate the freshness of an egg in the light and in appearance. So, in the light of a lamp or the sun, a fresh egg will shine through, a spoiled one will turn out to be darkened. A fresh egg has a shiny shell, a stale one is dull.
Sound check method
You can determine how fresh the egg is by the sound. To do this, it is worth shaking him a little and listening. Fresh inside will not have any echoes and hesitations. For stale ones, the contents will dangle and beat against the walls. Without a doubt, such an egg can be thrown away immediately.
Marking
The markings on the eggs will also indicate the freshness of the product. Diet eggs laid no later than seven days ago must have a date. The eggs of the canteens, those laid seven to twenty-five days ago, have no marking date and the existing markings are in blue.
Shelf life of eggs
Eggs are perishable foodstuffs. That is why it should be kept in the refrigerator. It is not recommended to wash the eggs before sending them for storage, as the biologically active protective layer of the shell will be disturbed.
You can store fresh eggs for 3 to 4 weeks. The shelf life of fresh egg whites is 2-4 days, egg yolks in casings are also from 2 to 4 days. Hard-boiled eggs with a whole scallop are stored for a week. If the eggs have been cooked using spices, the shelf life is 2-3 days. Other egg dishes should be stored for no more than 4 days.
