Are the slippery eggs not ripe?

Slippery eggs, Guangdong people's practice is slippery, and the eggs are fried until they are basically solidified and moist, smooth and tender and golden.

Introduction to eggs:

The complete eggshell is oval, with a big end and a small end, accounting for about 1 1% to1.5% of the whole egg volume. Eggshell can be divided into upper shell membrane, lower shell skin and air chamber.

The main component of eggshell is calcium carbonate, which accounts for 9 1% to 95% of the whole eggshell. Its calcium-containing components are the same as those of pearls, oysters, beef bones and dried fish, and it is a good source of calcium. Shell membrane: an opaque and unstructured membrane outside the eggshell; The function is to prevent the water of eggs from evaporating.

In addition, the eggshell also contains about 5% magnesium carbonate, and 2% calcium phosphate and colloid. Subshell skin: the membrane in the eggshell, which has two layers; Air can pass through this film freely.

Air chamber: the gap between the lower epidermis of the second shell; If the gas in the egg is lost, the air chamber will continue to increase. After the eggshell is soaked in vinegar or some acidic solution for a period of time, it will disappear and become a shell-free egg, leaving only a film.
