How to distinguish raw eggs from cooked eggs?

You can beat eggs on a flat surface. If the egg is raw, the rotation speed is slow, and the cooked egg is fast.

Because the yolk of the boiled egg is twisted together when it is twisted, it turns smoothly. On the contrary, when a raw egg is twisted, only the shell is stressed, while protein and yolk are hardly stressed. According to Newton's first law (law of inertia), protein and yolk are almost motionless because of inertia. As a result, the rotation of the eggshell was slowed down by protein.

Eggs, also called chicken eggs and eggs, are laid by hens. There is a hard shell outside, and there are air chambers, egg whites and yolk inside. Eggs can be divided into three parts: shell, protein and yolk. Eggs contain a lot of vitamins and minerals and protein with high biological value, which is one of the foods commonly eaten by human beings.

There are many ways to eat eggs, such as boiling, steaming, frying and frying. As far as the absorption and digestibility of egg nutrition are concerned, boiled eggs and steamed eggs are 100%, tender eggs are 98%, scrambled eggs are 97%, poached eggs are 92.5%, old eggs are 8 1. 1%, and raw eggs are 30%~50%. From this point of view, boiled eggs and steamed eggs should be the best way to eat.

But pay attention to chew slowly, otherwise it will affect absorption and digestion. But for children, steamed egg soup and egg drop soup are the most suitable, because these two methods can release protein, which can be easily digested and absorbed by children.
