How to identify the freshness of eggs?

How to identify the freshness of eggs, the simplest and most accurate way is to put the eggs into a basin of water, completely sink to the bottom of the basin, is very fresh, can not completely sink to the bottom of the basin, and the bottom of the basin has a certain distance, indicating that it is not fresh enough, if the whole egg floats on the water, it can be said that the egg has finished broken.

Hope it helps.

First, from the appearance.

Eggs feel good when you put them in your hand. Fresh eggs have a rough feel, with a raised surface and a layer of white frost, which is a protective film of itself; Stale eggs feel smooth to the touch in the hand, and will be shiny to the light, such eggs are very stale eggs; There are some black dots on the surface of the egg, and if they come out of the shell, the egg is rotten and cannot be eaten.

2. Test freshness.

Place the egg in the water and see if it floats. The egg has a small air chamber, and over time, air will slowly enter the egg through the small holes in the shell. The more air that enters the egg, the larger the air chamber in the egg and the easier it is for the egg to float.

If the egg sinks horizontally to the bottom of the bowl, then the egg is at its freshest.

If the egg stands up, but one end is still in contact with the bottom of the bowl, then the egg is past its freshest time, but it is still ready to eat.

If the egg floats, then it is not fresh anymore. But that doesn't mean it's spoiled or inedible. You still need to knock it open and tell if it has gone bad by looking at or smelling it.

3. Sound. Hold the egg to your ear and shake it to see if there is any sound. As eggs age and become wet, the carbon dioxide in the eggs will seep out of the shell, the yolk and egg whites will slowly shrink and dry out, and the air cells will become larger and larger.

5] The larger the air chamber, the larger the space for movement inside the egg, so when the egg is shaken, the louder the sound inside is.

Fresh eggs should not make any noise, and if they do, they will not be very loud. When you shake an egg, you make a loud noise, which only means that the egg is not fresh, but it does not mean that it is not edible.

First look at the surface of the egg shell to see if there is anything unusual, then touch the egg, then smell the egg, and finally shake the egg gently. The surface of the fresh eggs is not unusual, but it is very rough to the touch, and it smells of eggs, and there is no sound when shaken. First of all, we must see if there is anything wrong with the surface of the eggshell, those eggshells have blood on them or the color of the eggshells is dark and light, or there are colored spots on the eggshells, such eggs must not be chosen, it must be that the chickens themselves have problems, so the eggs look good!

When choosing eggs, be sure to pay attention to the tactile sensation of the eggs. This is very important, and it is also an important way to distinguish between fresh eggs and old eggs, fresh eggs are very rough to the touch and have a strong texture, while old eggs will be very smooth, not as textured as fresh eggs. Although the egg has a shell on the outside, the egg shell is still breathable, and the fresh egg can smell a unique egg fishy smell, if it smells sour or other peculiar smells, it is said that the egg is broken, and such an egg can not be wanted.

Take the egg in your hand and shake it gently so that the egg touches each other, and listen to its sound; Or shake your hands and listen to their sounds. The sound of good quality fresh eggs hitting each other is crisp, and the eggs shake silently. Inferior fresh eggs make a mute sound (cracked eggs) when they collide with the eggs, and the contents feel fluid when the hand shakes.

First: Look. To select fresh eggs, we need to look at the surface of the eggshell that is shiny and complete, and there is a layer of hoarfrost on the eggshell.

Precautions for refrigerating eggs

What to do with refrigerated eggs

If it is a product with packaging produced by a regular manufacturer, it generally does not need to be cleaned, and it can be directly put into the refrigerator for refrigeration.

If it is a loose egg, you need to check whether there is anything unclean such as feces on it; In order to prevent moisture when refrigerating, it is best to take paper packaging, if it is not packaged, it can also be covered with a layer of paper on the eggs to absorb moisture;

If there is obvious dirt, it can be stored separately in a paper package, or it can be washed, but after cleaning, it needs to be coated with a layer of cooking oil and then refrigerated;

1. Observe the eggs. Fresh eggs have small granular bumps on the skin and are slightly pale in color. Stale eggs will have smooth shells or black spots on the skin.

2. Bump eggs. Putting two or more eggs in your hand and colliding with each other can make a crisp sound, indicating that the eggs are relatively fresh. If it makes a dull sound, it means that it is an aged egg or a spoiled egg.

In the daily diet, eggs are often eaten, cakes need to be beaten with eggs, fitness needs to use eggs to increase muscle, and when cooking on weekdays, eggs have more tricks. But have you ever thought about it, the bulk eggs that you usually buy at home can't see the production date at all, so how to judge whether the eggs are fresh or not?

1. From the outside: the egg feels good in the hand. Fresh eggs have a rough feel and will have a bulge and a layer of hoarfrost on the surface, which is a protective film.

If the egg is not fresh, it will feel smooth and shiny to the touch. If there are some black spots on the surface of the egg, and it is peeking through the shell, the egg is rotten and inedible.

2. Test the freshness: Put the egg in the water and see if it can float. The egg has a small air chamber in it, and over time, air enters the egg through the small holes in the shell.

The more air that enters the egg, the larger the air chamber in the egg and the easier it is for the egg to float. If the egg sinks horizontally to the bottom of the bowl, the egg is at its freshest. If the egg stands upright, but one end is still touching the bottom of the bowl, the egg has passed its freshest time but is still ready to eat.

If the egg floats, it is no longer fresh. But that doesn't mean it's spoiled or inedible. You still need to tap it to see if it has gone bad, by looking or smelling.

3. Sound: Put the egg to your ear and shake it to see if there is any sound. As eggs age and become damp, carbon dioxide in eggs will seep out of the shell, yolks and proteins will slowly shrink and dry out, and the air chambers will become larger and larger.

The larger the air chamber, the more space there is to move inside the egg, so when the egg is shaken, the louder the sound inside becomes. Fresh eggs should not make any noise, and even if they are, they will not be loud. A loud noise when shaking an egg simply means that the egg is not fresh and not inedible.
