Artificial eggs are characterized by their powdery taste, and they can't smell the original fishy smell of eggs (of course, this is not edible after seasoning). Real eggs have a film in their eggshells, but artificial eggs don't.

Moreover, after artificial eggs are fried, there will be many bubbles on the surface of the eggs, while boiled eggs look no different, but people with keen taste will taste a little chemical.

From the appearance, there is basically no difference between the shell of an artificial egg and a real egg, so it is difficult to distinguish it without paying attention.

But even the freshest eggs are rarely so fresh that you can't see the air chamber at all, so you may eat artificial eggs.

As for the cost and price, artificial eggs are definitely dozens of times cheaper than real eggs, because there is no need to open up farms to raise chickens, feed them, care about and worry about natural disasters or other factors, so they cannot be more expensive than real eggs.
