Sometimes chicken eggs lie in the refrigerator, and the hostess can no longer remember how long she has been keeping them. In order to protect your family from poisoning with stale eggs, it is worth checking the suitability of each of them before using.
Instructions
Step 1
Take an egg in your hand and shake it lightly. If it is fresh, then you will not feel much shaking inside the shell. If the egg is stale, then its internal content will actively move.
Step 2
Use water to determine the quality of chicken eggs. Put cool water in a saucepan or deep bowl and dip the eggs into it. Fresh eggs will remain at the bottom in a horizontal position, those that lie in the refrigerator for a week will lie in the water at an angle, and stale eggs will float to the surface vertically. This method is based on the fact that the longer the egg lies, the more air is collected in it. Accordingly, it is the air that has accumulated inside that pulls stale chicken eggs to the surface.
Step 3
The freshness of an egg can also be determined externally. The tone of fresh chicken eggs is even, the shell is clean and slightly shiny. Obscured eggs are dull, whites turn grayish or acquire a yellow tint.
Step 4
Eggs can also be checked when purchased in a store. To do this, you should use the ovoscope - a special device for checking the quality by means of their transmission. Fresh egg whites are completely translucent, with the yolk in the center. Eggs that have lain for a week or two will also show through, but you will notice small dark areas on the squirrel. Spoiled eggs do not show through at all.
Step 5
A quality check can be done by breaking an egg on a plate. When doing this, pay attention to the protein. In fresh chicken eggs, it is lush, has a rounded shape, fits tightly around the yolk, has two layers - a dense jelly and a liquid outer layer. Old eggs lose the duality of their protein, breaking it, you get the yolk and liquid protein mass on the plate around.
