Why do people only eat fish wings but seldom eat shark meat? Can you tell us something about it?

Why do people only eat fish wings and seldom eat shark meat? Is it really hard to swallow? Shark's fin is a kind of seafood with rich nutritional value, which often appears on people's table with abalone. And as long as shark fin is mentioned, the word wealth will appear in most people's minds. In ancient times, before the appearance of steel ships, people could only fish with traditional nets. Fishermen drive rickety boats out to sea to fish, and sharks are fierce and aggressive. Under normal circumstances, it is difficult for fishermen to catch them. Therefore, as the old saying goes, things are scarce, and the extremely rare shark fin has become a symbol of a rich family. But there is a problem here. Since sharks are rare, why did the ancients only eat that small piece of shark fin on him?

The dominant shark in the ocean, the shark is considered to be one of the fiercest animals in the ocean. There are about 380 species of sharks in the world, 30 of which are particularly fierce and will take the initiative to attack humans. Some tyrannical sharks can even do harm. They have lived on the earth for about 400 million years, and their appearance has not changed much so far, but shark meat really turns people off. How bad is it? Don't look at the skin of a shark. But it also has scales. Shark scales are small and dense. Non-professionals may take a long time to completely scrape their scales. Of course, some friends may say that it is better to cook the fish scales thoroughly after cooking for a long time. However, if you don't scrape the scales carefully, shark meat tastes like sand and is very ugly.

The most terrible thing about shark meat is not that it is difficult to handle, but that it smells bad. We also know that sea water is salty, and its salt content is high. In order to survive in the sea, sharks are slightly different from animals on land. Many people on the Internet say that sharks urinate through their skin, so shark meat tastes coquettish. This statement is not objective enough, because sharks have a fat cavity, through which they usually urinate and defecate. However, it is worth mentioning that the acid shark does not urinate through the skin, but it still has a lot of urea in its body. After urea metabolism, it will produce unpleasant ammonia gas, so shark meat always has a toilet smell that is difficult to remove.

Shark meat contains trimethylamine oxide, which can poison people if it is not handled properly, so people usually don't eat shark meat. Finally, the original intention of many people to eat shark's fin is to supplement the body's nutrition, but scientific research has proved that shark's fin is only a part of shark cartilage, and it does contain some protein, but these protein are all incomplete protein, so it is difficult for the human body to absorb them. So if you want to supplement protein, you might as well eat more eggs and drink more bottles of milk. Shark fin is not as magical as everyone thinks. I guess it was not easy to catch sharks in ancient times, but the shark meat was so rotten that fishermen didn't want to give up this big product, so they cut off their shark fins and sold them to rich people. In this way, shark fin has been on fire for thousands of years. Until now, it is still a rare tonic in consumers' minds.
