When we eat shrimp, do we need to remove the shrimp head and tail?

Can you eat shrimp heads? Some people say that shrimp heads are rich in calcium, wrap them in flour and fry them, which is crispy and delicious and calcium-replenishing. Some people say that shrimp heads are rich in heavy metals, and eating too much of them is definitely not good for your health and must be thrown away!

However, there is also controversy over the happy matter of eating shrimp, and the common one is "Can you eat shrimp head?" Let's take a look at this this time. I just looked at the others, and I found that all of them are creators in the field of food, so I, as a creator in the field of agriculture, agriculture and agriculture, will start fromBiology of prawnsLet's talk about itWhat's in the shrimp head

The organs are indeed in the head, the liver, ovaries and stomach are all there, and the food that is not digested well will indeed exist in the head of the shrimp, and the shrimp head does have feces, which may accumulate a large amount of heavy metal substances, so it must be cleaned before eating.

<> for the general public, when it comes to shrimp heads, there are several that need to be popularized. For example, there has always been a folk saying that "shrimp heads are rich in heavy metals", "shrimp heads turn black because of excessive heavy metals" and so on. There are thousands of types of shrimp, some large and some small, there are seawater shrimp, freshwater shrimp, crayfish, Jiwei shrimp, river shrimp, green shrimp and so on, so about whether the shrimp head can be eaten, how can it be generalized, but also depends on how to eat!

When some people eat shrimp, they always feel that eating shrimp and removing the shrimp head is purely superfluous, and even seems very wasteful. Indeed, a shrimp is so small in total, and if you remove some of the shrimp heads, there are almost very few that can be eaten.

"Shrimp head" is the cephalothorax of shrimp, and the division between the head and thorax of shrimp is not obvious, which is collectively called cephalothorax. The cephalothorax has a structure called the pericardial sinus, which includes the stomach, liver, heart, a pair of sperm nests, ovaries, and excretory organ antennal glands (because it is green, so it is also called the green gland). A few cents a pound of **, buy home stewed radish shreds, tofu, make shrimp head sauce, etc., are very delicious.

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 heavy metal content was higher in tilapia and vannamei shrimp.

There is a positive correlation between growth in the body and its weight.

Sex; 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.

Especially in the small river ditch, the head of the crayfish is even more inedible. Not to mention the pollution of small river ditches, many of which are about to become stinky ditches.
