How to tell if raw eggs are bad

Put an egg in a basin filled with water. If the egg floats, it means the egg is bad. This is because the protein in the egg will produce gases such as ammonia and hydrogen sulfide. When there is gas in the eggshell, the specific gravity of the egg is smaller than that of water, so it will float in water.

Eggs, also known as chicken eggs, are eggs laid by hens. Eggs are composed of eggshell, shell membrane, albumen, embryonic disc, yolk ligament, cuticle, yolk membrane, and eggshell.

Every 100 grams of eggs contains 12.58 grams of protein, mainly ovalbumin and ovomucoid, which contain 8 essential amino acids for the human body and are very similar to the composition of human protein. The human body's absorption rate of egg protein can be as high as 98%.

Every 100 grams of eggs contains 11 to 15 grams of fat, which is mainly concentrated in the yolk and is easily digested and absorbed by the human body. The yolk is rich in lecithin, sterols, lutein, as well as calcium, phosphorus, iron, vitamin A, vitamin D and B vitamins.

4 ways to preserve eggs in summer

In summer, eggs can be preserved by refrigeration, salt application, oil application and bran filling. The temperature in summer is relatively high, so it is necessary to find a suitable method to preserve them. Although the methods used are different, they can effectively extend the shelf life of eggs in summer.

Refrigerating eggs in the refrigerator is the most convenient and common method, which effectively preserves eggs through low temperature.

If you don’t have a refrigerator, you can also try applying a layer of cooking oil or salt on the egg shell. This can also effectively prevent bacterial invasion and effectively extend the shelf life of the eggs.

You can also put the eggs inside the bran, then wrap it up and store it in a cool and ventilated place. This is also a very effective method.

Egg structure

Eggs are generally oval in shape and are composed of eggshell, eggshell membrane, air chamber, egg white, yolk membrane, yolk, ligament, and germinal disc. The main component of the eggshell is calcium carbonate. The yolk membrane is located between the yolk and the egg white and plays a protective role. The yolk is generally located in the center of the egg white and suspended at the two poles by the ligament.

Eggs are high in protein and have extremely high nutritional value. Eating one a day is very helpful to human health.

The air chamber of an egg is usually at the big end of the egg. It is recommended that you place the eggs with the air chamber end on top.
