What's the difference between a real egg and a fake egg?
Fake egg has no nutrition, and it is easy to get dementia if he eats too much. I decided to learn some methods to identify fake eggs first, and then eat fake eggs and eat them as "dementia". I checked the relevant information, and used this weekend to "investigate" the vegetable market, simulated the relevant process, and found out a little bit of "experience" in identifying fake egg. Here, I want to talk about it. 1, from eggshell. Real eggs are raw chickens. In the process of making, some liquid may be attached to the egg more or less, which may be blood, other white things, or even a little chicken manure ... These signs can initially indicate that the egg comes from chicken PP, not real eggs; Fake egg is man-made, generally there will be no chicken manure on it. Very clean. They are all about the same size. In addition, although the main components of real eggs and fake eggs are calcium carbonate, the shell of fake eggs contains a small amount of gypsum, so it is brighter than the shell of real eggs, but it is not obvious. Only by careful observation can it be seen. 2. From the taste of raw eggs. Real eggs smell like fish. The main components of fake egg are resins, starch, coagulants, pigments and other chemicals, but there is no fishy smell. Egg yolk and egg white are very light. If it is an unsanitary vegetable market (such as Bitang market, Pu Jun market, etc.). ), you can look at a broken egg on the spot and put it in front of your nose to smell it to see if it smells fishy. If it doesn't smell, look for flies (flies are not uncommon in vegetable markets). If the fly is busy elsewhere but doesn't bite the cracked egg, it is probably a fake egg. At the scene, you may not be able to break the close smell of eggs, so it is not too late to buy them and break the close smell. If there is no smell, it may be a fake egg. 3. See through the color and shape of eggs. The main components of fake egg are resins, starches, coagulants, pigments and other chemicals. Egg yolk consists of pigment and resin. Egg white is not sticky, and yolk is light in color. It will be mixed with egg white soon after being broken, and it smells tasteless, and it will disperse after being cooked. Such eggs, 80% are fake egg. 4. Judging from the taste after frying. The chemical composition of fake egg determines that boiled eggs have no flavor of real eggs. I like to eat scrambled eggs with chopped green onion. Generally speaking, scrambled eggs can give full play to the fragrance of eggs more than boiled eggs or soup, so if you want to know whether the eggs are true or false, you'd better fry one. 5. From the structure of eggs. Real eggs are egg cells, eggshells are cell walls, egg whites are cytoplasm, and yolk is nucleus. There is a thin film between eggshell and egg white, which is called cell membrane. Usually, one end of a real egg has a small air chamber (between the cell wall and the cell membrane) to store the air for breathing. Fake eggs don't have this air chamber, or even a cell membrane. You can peel a boiled egg to identify it.
