A trick to identify fresh crayfish

How to tell whether the crayfish eaten in the restaurant is alive or dead? It can be judged by the shape of the cooked crayfish: if the tail of the lobster is found to be straight, then these lobsters are dead shrimps, so don't eat them. If it is curved and curly, it means that it is live shrimp and can be eaten. Crayfish should not be fried quickly. If the cooking time is not enough, the parasites in crayfish can not be guaranteed to be completely killed, which is not conducive to health. In addition, crayfish heads are easy to accumulate heavy metals and bacteria, so it is best not to eat them.

Pinch your stomach to distinguish the glue-injected shrimp

According to experts, after the death of aquatic products such as shrimp, the abdominal cavity and body parts will become soft. If your stomach is particularly bloated and difficult to pinch, you must be careful to be "injected". When cooking, you can cut along the abdominal cavity to observe whether there are transparent colloidal substances flowing out of the shrimp, especially the head connection part. In addition, if you find that aquatic products have peculiar smell in cooking, the gum is not easy to dissolve, and harmful industrial gelatin may be added, so don't eat it.

If it is smaller, you can eat it with a shell. The calcium content in shrimp shells is high, but it is not easy to be absorbed by the human body and can only play a role in supplementing calcium.

The northern lights are blackheads.

Experts said that this may be a sign that the head of the cooked shrimp is black or even falling off, but the wild Beijing shrimp is not like this. The "blackhead" of Beijing shrimp is normal.

When people salvage Arctic caribou shrimp, they use a big trawl to pull the shrimp from the bottom of the sea at one time. Sudden changes in atmospheric pressure may cause stomach rupture. The belly of the Arctic shell grows on the head. With its transparent shell, the black or brown plankton or algae eaten by shrimp will spread, and the head looks black. In addition, mature shrimps are sometimes found in the ovaries of female Beijing fish during spawning, and dark green appears faintly on the head. These may be the reasons for the "blackheads" of Beijing fish. Eating this "black-headed" shrimp will not cause harm to the human body. If it is visually unacceptable, remove the shrimp head.

But for river shrimps such as green shrimps, if they have become blackheads, it is best not to buy them or eat them.

In short, although it is not easy to eat safely, don't forget to practice a pair of eyes to distinguish rumors ~
