(2) Smell: Artificial eggs have a strong smell of chemicals, while real eggs have a fishy smell after opening, regardless of eggshell and yolk.
(3) Look at the pores: Observe whether there are pores in the eggshell under strong light, and some are generally real eggs. Fake eggs are extremely smooth and have absolutely no pores. 、
(4) Hand shaking: Real eggs are particularly strong, fresh eggs will not feel shaking inside, and artificial eggs will make a noise. This is because of artificial eggs. The added chemical components will not collide, and once shaken, water will overflow from the coagulant.
(5) Look at the egg yolk: Soon after the artificial egg is opened, the egg yolk will fuse together, because the egg yolk is not wrapped by a film and is made of the same chemical. Moreover, when frying eggs, the yolk will automatically spread out and cannot form a round yolk.
According to the data, the shell of artificial egg can not be distinguished from the real one. The main ingredient is calcium carbonate, but artificial eggs contain some gypsum. The most intuitive way is to see if there is a layer of white film around the yolk. Many real eggs will have a layer of white floc, which is the material of the embryo inside the egg. And fake eggs can't make this layer of material anyway.
The main components of artificial eggs are resin, starch, coagulant, lemon pigment and so on. Many underground factories use additives indiscriminately, so eating these eggs is definitely harmful to your health.
You should be careful when you meet very cheap eggs. Generally, the foreign eggs on the market are only a kilo of 4.5 yuan, while the artificial eggs cost 50 cents each, with a minimum of 20 cents. One person can cook 1000 eggs a day in a "dirty" workshop.
