There are many ways to make crayfish, which are delicious and nutritious. Eating them in moderation can supplement the nutrients needed by the human body and is good for the body. Many people will cook crayfish at home. When you cook crayfish, you usually clean them first, and most of them have to go to the head and gills to remove the shrimp line, or you can cook them together, but it is better to eat only the shrimp tail when eating, which is healthier.

First, can crayfish be cooked whole? Yes, but try not to eat shrimp heads when eating. It is recommended to eat only shrimp tails.

First of all, we must ensure that everything has two sides. Lobster head is of course good, clean, hygienic and time-saving. The disadvantage is that there is no shrimp yellow. You know, shrimp yellow is the soul of crayfish. The lobster has no head, the shrimp stays yellow, and the soul is still there. But what sticks to the shrimp yellow is other unknown objects. This kind of food will be dirty and is not recommended.

Generally speaking, crayfish eaten in restaurants will not be beheaded. The main reasons are as follows: First, it is very troublesome to remove crayfish. In order to save manpower, the crayfish in the restaurant don't go to the head; Second, the price of crayfish in many restaurants is based on Jin, and crayfish without head can increase weight and profit; Third, many people go to restaurants to eat crayfish and enjoy chatting while peeling their shells. If the head of crayfish is removed, it is unnecessary.

Second, how to eat crayfish 1, open the back shrimp line to eat meat and eat lobster, you must first remove the intestines of the shrimp. There are a lot of dirty things in it, which can't be eaten and also affects the taste. How do we move them? Open the shrimp back and tear a small hole in the shrimp meat along the yellow color, and you can see the long shrimp line. Before eating meat, we pick it out with toothpicks.

2, shrimp tongs meat is easy to eat We all know that there is meat in shrimp tongs, but it is difficult, so many people give up. Actually, it's not difficult to open it. Just grab the big pliers and twist them gently to split them in half. At this time, a large piece of meat will be exposed. Just pour it out and eat it. It's delicious and fun!

3. When eating crayfish heads, many friends throw their heads away directly. Although the content of heavy metals in the head is high, there are also edible parts. For example, shrimp yellow can't be missed. It is not only delicious, but also nutritious. When we eat, we just need to find out its location and take it down directly, and the rest may be gone.

Iii. Precautions for eating crayfish 1. Thoroughly clean the abdomen and pliers of crayfish. The structure is very complicated, and it is easy to shelter evil people from evil.

Therefore, the crayfish bought home should be put into the water for 2~4 hours to make it spit out impurities such as sediment; Then brush the shrimp body, abdomen and claw roots repeatedly to remove the dirt in the cheeks.

At the same time, the catgut containing a lot of sediment and bacteria should be removed, and then washed with clear water for 2-3 times.

The method of removing shrimp line: put the tail nail in the middle of crayfish tail and twist it left and right until it breaks, then gently pull the twisted tail nail and slowly pull out the shrimp line.

2. The living environment of cooked crayfish makes it carry a lot of parasites and pathogens.

Only after a certain period of high-temperature cooking can the parasites and pathogens in crayfish be killed.

Therefore, the most important thing to eat crayfish is to cook it thoroughly, that is, the temperature reaches 100℃ C and continue cooking for more than 20 minutes.

3. Don't eat shrimp heads. From the health point of view, eating crayfish head is not recommended.

Generally speaking, heavy metals in water enter crayfish through gill breathing or feeding channels and accumulate in different tissues.

The accumulation of heavy metals is the lowest in shrimp meat, and the highest in shells and digestive organs.

Because the liver, gills and other tissues are located in the head of shrimp, generally speaking, the head of crayfish is easy to accumulate heavy metals, which is also the hiding place of microbial parasites. So shrimp heads are not recommended.

4. Don't let the protein content of crayfish be too high overnight. Corruption in protein is also very harmful to human health. So, don't eat the rest of the crayfish, and don't eat too many crayfish.
