What color is the yolk of a black egg?
Slightly darker than ordinary egg yolk, orange yellow.
Compared with eggs, black-bone eggs have the characteristics of low fat and cholesterol, with large yolk and thick egg white. Has the effects of enhancing immunity, improving anoxia resistance and resisting aging. Scientific research has proved that selenium, a trace element in food, is known as the king of anti-cancer. Regular consumption of selenium-enriched foods can enhance human immunity and delay aging. Black eggs, fried in vegetable oil, are golden in color, rich in yolk, fresh and delicious, and the nutritious yolk is white and clear, with a long fragrance.
How to distinguish true and false black eggs
Although the main components of real black-bone eggs and fake black-bone eggs are calcium carbonate, the eggshell of fake black-bone eggs still contains a small amount of gypsum, so it is slightly Huang Liang than the eggshell of real eggs, but it is not obvious, and it can only be seen by careful observation. The identification method is as follows:
1. Touch the shell of a fake black-bone egg, and it will feel rougher than a real black-bone egg.
2. Smell it carefully with your nose. Real black-bone eggs will have a faint fragrance. The main components of fake black bone eggs are resin, starch, coagulant, pigment and other chemicals. There is no smell. Egg yolk and egg white are very light.
3, tap gently, the sound of the real black egg is crisp, and the sound of the fake black egg is boring.
4. Soon after the fake black-bone egg was opened, the yolk and egg white melted together and the pot was scattered. This is because egg yolk and egg white are made of homogeneous raw materials.
5. When frying fake egg, you will find that the yolk will naturally disperse without stirring. This is because the film wrapped with artificial egg yolk is cracked by heat. Generally speaking, frying black eggs can give full play to the fragrance of black eggs more than boiling or soup, so if you want to know whether black eggs are true or false, you'd better fry one.
6. After the fake black egg is cooked, it is chewed in your mouth, which is a bit like rubber. Not only does it have no egg smell, but it also has the same color as petals.
