Step 1
It is quite difficult to determine the freshness of eggs by their appearance, but remember that fresh eggs have a shell that is always clean and shiny. Eggs that are not too fresh have a matte shell and have a grayish or yellowish tint. If the egg is shaken, then the fresh one will quietly "sit" in the shell, and the low-quality one will sort of dangle a little.
Step 2
The easiest and most affordable way to test is to place the egg in a container of water. A fresh egg will immediately sink to the bottom and assume a horizontal position. If the egg is weekly fresh, then it will slightly rise with the blunt side up. The thing is that over time, air accumulates inside the egg from the blunt side. It is he who pulls the egg up. If the egg has taken an upright position, then its age is 2-3 weeks. You can still eat it, but store it no longer. However, this test can be inaccurate if there is a small crack in the shell through which more air could enter the egg.
Step 3
In industrial conditions, the freshness of eggs is determined by translucence. In a fresh egg, the white is easily visible, and the yolk is almost invisible. If there are slight darkening, then the egg is not too fresh. But a spoiled egg does not show through at all.
Step 4
You can determine the freshness of an egg by breaking it. Take a close look at the yolk and white. In a freshly laid egg, the yolk has a dense spherical shape. Around the yolk 2 layers of protein - inside - more dense, outside - spreading. A week old egg still retains its yolk shape, but the white is already uniform and spreads. The egg, which is 2-3 weeks old, has a flattened yolk and spreading white. To avoid spoiling the dish with a low-quality egg, it is best to break each egg into a separate bowl before adding it to the dish.
Step 5
Fresh eggs are stored in the refrigerator for 3-4 weeks, but broken eggs should be used within 2 days. The frozen egg mass can be stored for up to 4 months.
