Production of natural shark fins: Shark fins are taken from the fins of sharks, and after the sharks are "caught and returned to the shore", the shark meat must be processed as soon as possible, otherwise, the high content of urea will make some of the shark meat smelly. Shark fins are processed in a more tedious way by first removing the meat attached to the base of the fins and then going through eight procedures such as washing, heating, desanding, boning, picking the fins, removing the limbs, bleaching, drying, etc. The shark fins can be cooked into dishes. Shark fins can be cooked into dishes, sent into the mouth, but also after many complicated processes: first one or two days or even longer time soak hair to make it become soft and puffy, and then put into the water to heat, respectively, pot hair, gelatin, rolling simmering deodorization. Formal cooking, but also add a variety of ingredients, broth flavor, and then either steak or soup system. Such a cumbersome processing procedures, for the producer's skills is a test. Artificial Shark's Fin: Many fake shark's fins are made from low-cost winter powder or fish skin, gelatin, and some are bleached with industrial hydrogen peroxide, which is not only not nourishing to the body, but is also easy to negatively affect the body. Therefore, people can follow the five steps of "looking, smelling, tasting, tearing, and pulling" to distinguish the fake shark's fins before purchasing or consuming them. Identifying real or fake shark's fin is often a favorite discussion among gourmets. Some people have been eating shark's fin for many years without realizing that what they are eating is synthetic "fake shark's fin. The color of real shark's fin is natural and rich in layers; while the color of bad quality shark's fin is transparent, white, without layers, and looks like the texture of plastic. 2. Smell: Shark's fins bleached with medicated water or hydrogen peroxide will have a slight medicated odor. 3. Taste: Natural water-foamed shark's fins taste delicate, silky, soft with Q. Drug-foamed shark's fins are very hard to bite, hollow inside, and tastes like plastic. 4. Tear: Pure water-foamed shark's fins are silky and clear, while drug-foamed shark's fins are thicker, and you can't tear them off with chopsticks. 5. 5. Pull: The shark's fins foamed with natural water are more elastic, and after cooking, they will be as elastic as rubber bands; while the shark's fins foamed with drugs will be broken as soon as they are pulled due to the destruction of the organization. When it comes to the production method of fake shark's fins, Wang Jiazhuang said that in addition to identifying the real shark's fins, the foaming process of the shark's fins is also very important. If the natural water foaming, it will be swollen to 2 to 2.5 times the weight of the foaming before the foaming, and if the medicated water foaming, the shark's fins can be swollen to the original 3 to 6 times the weight of the foaming, and the two are compared to each other, and of course, the medicated foaming of the shark's fins can save a lot of money and the speed of the foaming process is faster than the natural water foaming. Foaming of shark's fin is the process of cooking. The foaming of shark's fin is a very important part of the cooking process, which not only affects the taste of the dish, but also has an impact on the health of the customers. Like Taipei Top Shark's Fin Restaurant or Xing Shark's Fin Restaurant where I am currently working, we insist on using the natural way of foaming to preserve the flavor and gelatin of the shark's fins.
