    1. Put the eggs in a basin full of water, if the eggs sink in the water, they are fresh eggs, and the eggs that float up are bad. This is because fresh eggs have a larger specific gravity than water, so they will sink when placed in water. When the egg is broken, the protein inside will produce gases such as ammonia and hydrogen sulfide, and if there is gas in the eggshell, the specific gravity of the egg will be smaller than that of water, so it will float when placed in water.

    2. You can take a bowl and beat an egg to see if the egg white and yolk are scattered, which means that it is broken. If it's not bad, it's the whole egg yolk and egg white.

    Identify the quality of eggs.

    The main methods are:

    1) Appearance method. The egg shell has a layer of hoarfrost powder, which is not very smooth when rubbed by hand, and the appearance is complete is fresh eggs, and the shell is smooth and dark, incomplete, and cracked is not fresh eggs.

    2) Hand crank. When buying eggs, pinch the eggs with your thumb, index finger and middle finger and shake them, the ones that have no sound are fresh eggs, and the ones that make a sound when they shake by hand are bad eggs. The louder the sound, the worse it is.

    3) Irradiation method. Gently hold the egg with your hand, observe the light, the good egg protein is clear, translucent, there is a small empty room at one end, the bad egg is gray and dark, and the empty room is larger. Some eggs have stains, which are a sign of old or spoilage.

    4) Floatation method.

    Judging whether the egg is bad or not, you can observe through the light, shake to listen to the sound or check the eggshell, the good egg will be translucent through the light, the outline of the egg yolk inside will be clearer, there will be no sound when you shake it in the ear, and the eggshell is generally complete. Bad eggs, on the other hand, are not transparent to light, the inside is relatively blurry, and there will be a sound of water when shaken in the ear.

    1. Transparent observation

    nbsp;When you look at the egg against the light, the good egg will be translucent, and it will be slightly red, and the outline of the yolk inside can be seen clearly. Whereas, bad eggs are not transparent to light and look blurry inside.

    2. Shake and listen

    nbsp;When the egg is placed next to the ear and shaken gently, if the egg is good, the air chamber and yolk of the egg will be intact and there will be no sound when shaken.

    After opening the egg, you will find that the yolk is scattered, the egg yolk is mixed together, or there is a musty smell, and the smell starts before the rot, so you can no longer eat it. This is the most direct way to judge whether eggs have spoiled.

    Eating spoiled eggs can cause great harm, especially for the elderly, children, pregnant women and other people with poor systems. Therefore, it is important to learn to distinguish whether eggs have gone bad, especially in hot summers, when eggs are more likely to spoil than in other seasons.

    If the yolk is nearly spherical and slightly raised, and the egg whites or whites are just gathered around it, the egg is fresh. If the yolk is a little deflated and the egg white is transparent, but still clumped, the egg may be a little stale, but it is still edible.

    Eggs go bad

    If the yolk is flat and the egg white is very thin and almost watery, the egg is spoiled. Place the eggs in a basin of cold water at a water level about twice the height of the eggs. If the eggs lie flat on the bottom, they are fresh.

    Fresh eggs will sink to the bottom of the bowl, and the repentant locust may be on the side against the bottom of the bowl. However, if it is tilted or upright in the water, it means that it has been stored for a longer time. Eggs that are a little stale will sink to the bottom of the bowl after about a week, but there will be a slight up-and-down fluctuation.

    The longer the egg is placed, the more moisture and carbon dioxide are lost in the egg, and the larger the air chamber in the eggshell. When the air chamber becomes larger, it is easier for the egg to float on the water, and it will make a shaking sound when it is shaken. Put the egg between your fingers and shake it in your ear, and the fresh egg will not make a sound.

    Rotten eggs have the sound of slag, and the big ones have the sound of hollowing. Cracked eggs have a crackling sound, and those with the sound of water are eggs that have been left for too long.
