Boiled prawns, garlic lobster, spicy crayfish...... The names make your mouth water, but the controversy caused by shrimp has not stopped from the moment it is served on the table.
After all, it is fresh, and the safety of shrimp is the most concerned by everyone. There is a question that has been repeatedly mentioned, that is, what is the black line on the back of the shrimp, and can it be eaten at all?
What exactly is a shrimp line?
There are many types of shrimp, and according to the different sources of production, they are generally divided into two types: marine shrimp and freshwater shrimp. No matter what kind of shrimp it is, the long black line on the back of the shrimp is what we call the shrimp line.
In fact, the shrimp line is the digestive tract of the shrimp, which is used to metabolize the waste products in the shrimp's own body. This shrimp line runs from the head to the tail of the shrimp, the head is connected to the "stomach" of the shrimp, and the tail is connected to the place where the shrimp excretes.
So in more layman's terms, the shrimp line is the food that the shrimp has not digested and the stool that has not been excreted after digestion. The shrimp line itself has no health risks, but when you see this description, everyone will still have some psychological reactions.
If we don't remove the black line of the shrimp before cooking, after the shrimp is cooked, the black line will be more obvious, in fact, the excrement of the shrimp is not completely discharged, so many people refuse to eat the shrimp as soon as they see this shrimp line.
After understanding what the essence of the shrimp line is, I believe that many people will not eat the shrimp that has not been picked by the shrimp line, but in fact, in many coastal areas, those old fishermen who eat the sea by the sea eat shrimp at home, and they do not pick the shrimp line, and their shrimp taste is still very delicious.
In those coastal areas, freshly caught seafood, or fresh prawns sold in the market, many of them are eaten without removing the shrimp line.
The master must know how to eat shrimp better than most, why did they choose this way?
In fact, shrimp do not have any excrement in their bodies. In addition, this kind of shrimp has not been removed from the shrimp line, destroying the overall structure of the shrimp, after cooking, it will appear firmer and the taste will be more fresh and delicious.
All in all, knowing the composition of the shrimp line, how to eat it, and whether you want to eat it depends on your Xi.
It is worth mentioning that the other end of the shrimp line is connected to the "stomach" of the shrimp, which is also the part of the shrimp head. There is also something black in the shrimp head, but this black thing is the melanin produced by the enzymatic reaction caused by eating, and it is not the excrement of the shrimp, so it is edible after cooking, but it will affect the taste to some extent.
Some shrimp also have a black line on the abdomen, which is shrimp tendon, which is also edible, and the shrimp tendon can prove that the shrimp in front of you is lively and active.
It is worth noting that although these parts of the shrimp are harmless, they should still be cooked.
As long as it is aquatic products, whether they are farms or fished by themselves, there may be parasites and other bacteria in them, and they can only be eliminated by cooking at high temperatures, so if you eat shrimp, it is best to cook them for safety.
Therefore, whether the shrimp line on the shrimp head and abdomen is removed or not depends entirely on personal Xi, if you like to eat, you can eat it if you don't like it, and the shrimp line on the back tests the cleanliness and psychological tolerance of the taster.
In order to eat shrimp safely, there are other things you need to know
When some people eat shrimp, they are afraid that there are heavy metals in shrimp, but in fact, this worry is unnecessary.
Because whether there are heavy metals in shrimp is related to the food that shrimp eats and the water they drink. In general, after food and water enter the internal organs of shrimp, they will be metabolized through the internal organs, and the remaining things that are not metabolized are left in the shell of the shrimp.
Shrimp, a crustacean, has a biological characteristic, that is, molting, every time the shell is molted, the heavy metals will remain in the previous shell, and the heavy metal content in the new body will be greatly reduced. Before the shrimp are put on the market, the shell will be changed every 15 to 20 days, so when we buy the shrimp meat and then put it on the table, there is basically no metal quantity, so there is no need to worry about heavy metals.
After how to eat shrimp has a direction, everyone raises questions again. Some people say that shrimp and fruit can be poisoned when eaten together, is this true?
Actually, no. For the average person, the amount of lobster we eat and the amount of fruit we eat do not reach the point of poisoning. If you want to be poisoned when you eat shrimp and fruits, you have to eat hundreds of catties of shrimp and fruits at a time to reach the level of poisoning.
However, although we will not be poisoned, shrimp should not be eaten with fruits containing tannin, such as grapes, pomegranates, hawthorns, persimmons, etc., because after tannic acid and calcium acid meet, they will react to form calcium tanninate, which will then stimulate the stomach and intestines, and the human body is prone to vomiting, dizziness, nausea, abdominal pain, diarrhea and other uncomfortable symptoms, and it will also reduce the nutritional value of the protein present in shrimp meat.
Not only shrimp, but also other seafood should be avoided with these fruits, and even if they are eaten, they should be eaten at least 2 hours apart.
How to choose what makes a good shrimp?
Finally, there is the problem of choosing shrimp, now the transportation is convenient, and the types of shrimp in the market are rich and diverse, which is dazzling. Shrimp are generally divided into river shrimp and sea shrimp, so which one is better?
In fact, there is no difference between river shrimp and sea shrimp in terms of nutritional value, only the difference in taste. If you like to eat meat that is large and rich, and it is firm, then choose sea shrimp, but if you prefer to eat loose meat, the meat is more elastic, then you can choose river shrimp.
It's just that if we go to a shopping mall or a vegetable market to buy, try to buy fresh shrimp instead of frozen shrimp. Although the price of frozen shrimp is cheaper, frozen shrimp are frozen after they are caught, and the nutrients are certainly not as high as those of fresh shrimp.
And the market merchants are mixed, because the frozen matter can not be thawed temporarily, some unscrupulous merchants will even put the dead shrimp in transit in the frozen shrimp, if the dead shrimp and those originally fresh shrimp stay together for a long time, it will also infect the germs on the dead shrimp to these live shrimp.
Buying frozen shrimp is a test of experience, and it is easy to buy frozen shrimp of low quality. Therefore, everyone should compare shrimp according to their personal circumstances, and they can't be greedy for small profits and suffer big losses.
In short, the shrimp line is very disgusting for the structure of the shrimp, but if you can break through the psychological barrier and really eat it, there will be no health threat, and the shrimp is still delicious shrimp.
