In the food culture of Chinese, there are always some strange foods, which attract special attention because of their appearance or taste.
And there is a creature, a food that has always been regarded as delicious and nutritious, and people only know its deliciousness, but they don't know that there are many mysterious characteristics and some little-known secrets on its body.
For example, a creature like this will degenerate after reproduction, and its blood is poisonous, but it is still praised by the Chinese as the best river fresh, but these characteristics are little known.
I can't help but think deeply, why such a river fresh with many shortcomings can be called the best river fresh by people, and can be sold at such a high price?
What is the principle of degeneration of this organism after reproduction, and is the poison contained in its blood harmful to the human body?
«——【Common Eel·】——»
In fact, this kind of river fresh is the eel, also known as the yellow eel, which belongs to the freshwater fish. The eel is an animal with a very long history, and in China, it is widely distributed in the southern region. In the "Compendium of Materia Medica", the eel is a creature.
The "Compendium of Materia Medica" says that eel has a variety of effects such as blood nourishment, qi replenishment, and anti-inflammatory. In the mainland, since ancient times, there has been a saying that the small summer yellow eel race ginseng.
Back in ancient times. The Chinese made eel into food, eel is not just a simple food, it is more like a medicinal meal, the body of the eel is eel-shaped, the surface is smooth, the body surface is rich in smooth mucus, the head is round, the mouth is pointed. The eyes are small and look like a small snake.
In the eyes of us ordinary people, the eel is one of the most common animals, it often appears on our table, but few people know that the eel is actually a demutable animal.
Some people can't help but wonder how the eel degenerates after breeding, and why does this happen?
Eel reproduction occurs after reproduction, which is a biological sexual reversal phenomenon, when the eel develops to the first sexual maturity of the eel, its sex is female, at this stage, the ovaries of the eel will develop first, and the development of the sperm nest is inhibited.
When the female eel finishes laying eggs, her ovaries begin to shrink and the sperm nest begins to develop, in which the eel becomes in a hermaphroditic state.
Over time, the eel will eventually become male, so the eel's life is actually a state of going from female to hermaphroditic to male.
The main reason why eels have such characteristics is that this process of sexual reversal is an adaptation strategy of eels during the reproductive cycle.
This reversal of sex ensures that the eel retains its reproductive ability for a period of time after the female has reproduced, and the sex transition of the eel is not changed at birth.
Gender transition is influenced by a variety of factors, including water temperature, sound, light, etc., which can be key factors in the sex transition of yellow eels.
If there is a lack of males in the population, some females may even convert to males early. This is to maintain the reproductive capacity of the race.
It is important to note that the sex transition of the eel does not only occur after breeding, but can occur multiple times during the short life cycle of the eel, which means that a yellow eel may undergo multiple sex transitions during its lifetime.
In the body of the yellow eel, in addition to the fact that changing gender is a cold knowledge, people do not know that the blood of the yellow eel is still poisonous.
When it comes to poison, many people may be shocked, because after all, yellow eel is a very common ingredient in our daily life, and it is toxic in his blood, so why do we eat it for so long?
Yellow eel has been a common folk ingredient since ancient times, but I haven't heard of anyone who has problems eating yellow eel, so what is the toxicity in his blood?
«——【Eel is toxic in blood?·】——»
In fact, the blood of eels does contain a certain amount of toxicity, but this toxicity mainly exists in the remaining blood when eaten raw.
The toxic components contained are mainly serum toxins, which are not heat-resistant and can be destroyed by heating, so this is why we have been eating yellow eels for so long.
In the private sector, there are sometimes reports of poisoning caused by eating raw eels, and some people wonder what happens to the human body if eel is eaten raw.
If you eat eel raw, it may cause irritation to the mouth and digestive tract, and in severe cases, it may cause damage to the human nervous system, and even worse, numbness of the limbs and respiratory and circulatory system failure may occur.
However, when eel blood is cooked, its toxins are destroyed, so it is generally safe to consume cooked eel blood.
During the cooking process, the toxins can be destroyed by high temperatures, and the body's gastric juice can also break down these toxins, and the cooked eels can be absorbed and utilized by the human body normally.
Although it is a toxic ingredient, it still has a high nutritional value when cooked, and it is rich in DNA and lecithin, which are the main components that make up the cell membranes of various organs and tissues in the human body. It can be said that eating eel is very good for the human body.
In this way, it is not unreasonable for eels to be called the best river fresh, and now the market price of eels is rising, and now the farmed eels have been able to sell at a high price of 35 yuan a catty.
«——【·eel's market position·】——»
in different regions. The market price of eel has also fluctuated, and saying that eel is now 35 yuan a pound is actually underestimating its market position.
In some places, eels are even sold at a high price of 90 yuan a catty, and even claim that their eels are high-end products, and eels are also designated as high-end products.
In addition, the price of wild or organic eel will be higher, the price of farmed eel has been quite close to the people, and the price of eel is also affected by various factors such as season, supply and demand, quality, etc., in the eel breeding season, the price of eel will decrease.
The eel market has also shown continuous growth in recent years. As people's living conditions gradually improve, the demand for taste is also getting higher and higher, and many consumers are now paying more attention to deliciousness and recognition of nutritional value.
In this case, the demand for eel gradually increases. Because eel is a high-protein, low-fat, and nutritious ingredient, it is widely popular.
«——【·Conclusion·】——»
The unique taste and variety of cooking methods of eel also attract many diners, and eel also occupies an important place in traditional Chinese cuisine, it can not only be used as an ingredient, it can also be used as a medicinal material, and many consumers also use eel as a representative of urban health and deliciousness.
Now the price and status of eel in the market are quite high, and its delicious and nutritional value has also been recognized by many consumers, and the market for eel still has a lot of room for development.
