Children especially like to eat shrimp, and I also buy them casually. Today I heard a friend who poured seafood say that shrimp cannot be bought casually. Otherwise, eating it will be useless and harmful. He said: The texture of the general shrimp is particularly clear, the color is blue-gray, and when it is boiled, it is normally curved. And some of the texture is light colored, which is the chemical potion bubble is gone, and boiled out, the head and tail of the shrimp are connected, generally called this shrimp is crystal shrimp, also called emerald shrimp. What must not be eaten is the shrimp soaked in the fire alkali! This shrimp is crystal clear, this shrimp eat too much, no one can stand it! So I decided to buy the whole shrimp to take home and dispose of it myself, and the shrimp head can also be boiled with shrimp oil!
