Do you need to remove the head of a lobster when eating it?

Eating shrimp heads is equivalent to eating shrimp excrement, semi-digested shrimp food, and more importantly, shrimp heads will enrich heavy metals in the environment.

The heavy metal content varied according to the size and location of the sample, and the trend was that the heavy metal content of the large sample was relatively high, and the increase of heavy metal content in tilapia and vannamei shrimp was positively correlated with their body weight. The content of heavy metals in the viscera of tilapia was significantly higher than that in muscle tissue, and the shrimp head was the main part of the heavy metal enrichment of shrimp.

But there is indeed a very delicious ingredient in the shrimp head, that is, the shrimp eggs, commonly known as "yellow".

When the female shrimp reaches maturity, the head and neck will contain shrimp yellow, so the shrimp with shrimp yellow must be the female shrimp, but without the shrimp yellow, it is not necessarily a male shrimp, and the female shrimp is not mature and the shrimp yellow cannot be seen. Crab roe is common to most people but little knows shrimp roe, and the female shrimp contains shrimp roe on the head and neck of the shrimp before conceiving eggs, commonly known as "red head".

If you want to eat shrimp yellow, you don't want to eat anything else, you have to take your time when you eat, in fact, to remove the factors of heavy metals, the harm of its excrement to the human body is very weak.

In some places, there is a habit of eating shrimp head sauce, and after checking the method, it is true that the whole shrimp head will be used.

The "shrimp head" we often say is the cephalothorax of the shrimp, and the demarcation between the head and the thorax of the shrimp is not obvious, which is collectively called the cephalothorax. The cephalothorax has structures called pericardiac sinuses, including the stomach, liver, heart, excretory organs, antennal glands (also called green glands because they are green), and bladder and excretory holes.

Eat crayfish at home, and after buying it, you should first rinse it with clean water, and it is best to stock it in water for a day or two. Before cooking, remove the head. Then use a brush to scrub the shells. In addition, crayfish must be cooked, generally boiled over high heat for 30 minutes, and it is best not to eat more than 10 at a time.

When dining in a restaurant, if you see crayfish that are particularly bright but have fewer shrimp claws, it is more likely to use "washed shrimp powder", so you should be cautious about eating them. Before eating crayfish, you should also look at the body of the crayfish, such as the tail curled, indicating that it is alive before entering the pot. If the tail is very straight, it means that it has died before entering the pot, and the germs in the dead crayfish are easy to exceed the standard, so it is best not to eat it.

The head of the crayfish is not to be eaten.

The circulatory and respiratory and reproductive systems of shrimp are concentrated in the cephalothorax, and the abdomen can be said to be just an organ of locomotion. There are not only many formed eggs in the shrimp head, but also many other crayfish garbage toxins, the head of the lobster is very easy to absorb heavy metals and toxins, because of these reasons, eating the head of the crayfish may cause allergies and acute gastroenteritis, and the head and neck of the lobster are at risk of causing lung flukes.

In addition to the shrimp yellow in the shrimp head can not be eaten, there is a line in the body of the shrimp that cannot be eaten, the black line on the back of the shrimp's abdomen is its intestines, and the inside is of course shrimp poop, which should be removed before cooking. In addition to these, can not eat drunk shrimp, shrimp sashimi and other food, some parasites can shrimp as an intermediate host, take liver fluke as an example, its larvae "cysts" parasitize in the muscles of shrimp, people eat shrimp containing cysts may be infected with liver flukes. People think that they can kill the parasites in the food during high-temperature cooking, but scientific studies have shown that some parasites cannot be killed during the cooking process.

The head of the crayfish cannot be eaten, but the head of the large lobster that lives in the sea can be eaten when it is cleaned. Because the water quality of crayfish is poor, the head is the place where toxins are absorbed and processed the most, and it is also the most likely to accumulate pathogenic bacteria and parasites, so they cannot be eaten. The lobster lives in the sea or in artificially cultivated water with better water quality, and the food and head are polluted.

The head of the crayfish cannot be eaten.

The head of the crayfish we usually eat is basically not eaten, and there are 5 reasons for the following:

1. The water quality environment for crayfish to survive is not good.

Whether it is artificially farmed crayfish or wild crayfish, most of them live in some environments where the water quality is not very good, in addition to silt, there may be heavy metals and other pollution, and this kind of lobster is also easy to become a host for parasites such as schistosomiasis and liver flukes. The head of the crayfish is the place where the most toxins are absorbed and processed, and it is also the part where pathogenic bacteria and parasites are most likely to accumulate, so it cannot be eaten.

2. There is dirty excrement on the head of the crayfish.

In addition, the body structure of crayfish is also one of the reasons why we do not eat the head, the body of the crayfish has almost no other organs except for one intestine, and all the organs are concentrated on the head. These include the stomach, liver, heart, a pair of seminal nests and ovaries, excretory organs, antennal glands, and bladder and excretory orifices. In other words, if we eat shrimp heads, we will also eat shrimp excrement, semi-digested shrimp food, shrimp urine and other dirt.

3. The head of the crayfish is difficult to clean.

The head of the crayfish is not good due to the poor growth environment, the inside will be dirty, and it is difficult to brush the inside of the crayfish after feeding it with water for 24 hours in a timely manner, and the head of the crayfish is the dirtiest part of its body, because the place that cannot be washed is still not eaten.

4. There is no meat on the head of the crayfish.

The key thing to eat is shrimp meat, and the crayfish itself is small, and the meat of the whole body is concentrated in the shrimp body, and even if the shrimp head can be eaten, it is also a slag taste, basically no meat, and it is not worth the effort to clean and make food. However, because the shrimp head part is also high in amino acids, and amino acids are good ingredients for freshness after cooking, it is recommended that the shrimp head can be made together when cooking, but the shrimp head should be discarded when eating.

5. Eating the head of a crayfish may cause physical discomfort.

First, crayfish have gills on their heads, which will exchange with water from the outside world, which may be contaminated with a lot of bacteria and other substances, and eating them is easy to cause gastrointestinal discomfort; Second, there may be parasites or parasite eggs in the crayfish head, and parasite infections are likely to occur if not handled properly; The third is that there is a liver in the head of the crayfish, and the liver may contain more heavy metal ions, if you accidentally eat too much, it will lead to the accumulation of more heavy metal ions in the human body, which is not good for your health.

My advice is still not to eat, we don't eat the head of the crayfish every time, we all say that the head of the crayfish has parasites in it, but for the sake of safety, it is better not to eat it.

The head of the crayfish should not be eaten, because the head of the shrimp contains more heavy metals, which is harmful to the body if eaten.

Hello, it is better not to eat the head of the crayfish, there is no meat in the head of the lobster, and the digestive system of the shrimp is in the head, and the harmful substances are concentrated in the head, and eating it is harmful to the body.

It's best not to eat it. Because there are many harmful components in the shrimp head, general pollutants will accumulate on the head.

The black hair of the shrimp may be due to a problem with the feed, or tyrosinase produces some melanin, which has nothing to do with heavy metals.

Although shrimp heads do not necessarily contain heavy metals, it is important to note that they are the places where toxins are absorbed and processed the most, and therefore the most likely to accumulate pathogenic bacteria and parasites. It is recommended that when you eat crayfish, it is best not to eat the head and shrimp yellow part.

The gills of crayfish are on the head, and most of the internal organs are also in the head, so it is not recommended to eat the head, but most people will keep the head for the sake of shrimp yellow, so they will be processed in advance when eating and take out the stomach.

When eating a lobster, you will always find some black particles in its head, which are usually excrement and parasites in the body of Boston lobsters, and cannot be eaten.

Usually no matter what kind of lobster you are eating, you must try to eat only the meat of its tail, because the head of the lobster is its internal organs, and it is easy to accumulate some harmful things to the human body, and it is not good for the body to eat. Lobster is an animal that lives in the sea at very low temperatures, and its meat is very delicate and delicious, and has many cavity benefits for the human body.

The shrimp line of the lobster has to be drawn out at a loss:

The correct way is to remove the shrimp line, because the dirtiest part of the crayfish is in the head and shrimp line, so when eating crayfish, you should go to the shrimp line! Crayfish have scavenging and stain-resistant habits, and their heads and carapaces are most likely to absorb heavy metals, bacteria and parasite eggs. Although removing the shrimp line will affect the taste of the shrimp meat to a certain extent and may make the shrimp meat loose, it is recommended that you remove the shrimp line for the sake of hygiene and safety.

Need. The head of the crayfish is not edible, and the head of the crayfish is the place where the toxins are absorbed and processed, and the toxins are the most. In addition, the head is also the part that is most prone to the accumulation of pathogenic bacteria and parasites, and eating it is not good for the body. <

Crayfish need to be decapitated. The head of the crayfish should not be destroyed for consumption, and the head of the crayfish is the place where the toxins are absorbed and processed, and the toxins are the most abundant here. In addition, the head is also the brightest part where pathogenic bacteria and parasites accumulate, and eating it is not good for the body.

We all know that crayfish is a bit troublesome to eat, especially in the early stage of cleaning and cooking. Not all parts of the crayfish can be eaten, so remove these inedible parts before making them, such as the internal organs and shrimp threads inside the head. So when the crayfish is washed, the head is removed or when eaten?

Let's take a closer look!

Generally, after cleaning, cut off one-third of the head of the mountain bush to remove the stomach pouch and internal organs inside.

Generally speaking, the crayfish bought back should be soaked in water for two or three hours, add some spring cherry salt and white vinegar to the water, so as to remove the silt and dirt in the body, and then scrub several times, and then cut off one-third of the head with scissors, pick out some internal organs and dirty things, and then pick out the shrimp line by hand, and finally rinse it with water. The cleaned and processed crayfish can be cooked, and the head cannot be removed. When eating, you can break the shrimp tail and shrimp head, and eat the meat of the shrimp tail and the yellow inside of the shrimp head.

Eat lobster, lobster head will also have a lot of lobster yellow, will eat it is very simple, will not eat and afraid of eating bad things, after all, the suitable growth environment of lobster is sewage.

The stomach of the lobster grows at the front of the inside of the head and is a sac-shaped, slightly black, but it is actually easy to identify. When enjoying lobster, it's good to pay a little attention, and there is no need to give up the delicious lobster yellow for a small thing. Personally, I think that no matter how delicious the meat on the tail is, it is not as good as yellow.

The head of the lobster is high in heavy metals, especially lead, which is harmful to the human body if eaten, so it is best not to eat it.
