The specific method is to scrape the scales off and wash them. Put it into a pot full of water, add vinegar, keep the water temperature at 70 ~90 ~C and simmer slowly over low heat. After the fish scales melt slowly and the soup is thick, turn off the fire and cool it, then freeze it in the refrigerator. When eating, fish scales are frozen and mixed with seasonings. Fishbone
Fish bones are also known as fish bones, which are rich in calcium and other trace elements. After softening, their nutritional components are more easily absorbed by the human body.
Very small bony fish should be chewed hard. After entering the stomach, gastric acid will soften part of their bones and promote the dissolution of calcium, phosphorus and other nutrients. The big fish bone sucks its bone marrow, the white line in the fish spine.
In addition, fish bones can also be boiled with vinegar and boiled in small heat (2-4 hours). It should be noted that it is difficult to soften the fish spine when boiling the soup in white water. Stew it with more vinegar. Acetic acid can be used to promote the softening of the fish spine.

It is an ideal high-protein and low-fat food. The swim bladder wall of marine fish is thicker, and it is usually made into dried products, called fish belly.
The dishes made from fish belly are smooth, delicate and have a strong sense of taste. Fish bladder is rich in collagen and omega-3 unsaturated fatty acids, which may be beneficial to lipid control. Common practice is to wash the swim bladder with clean water and stew or braise with the fish.
Fish liver is the place where fish store many kinds of nutrients, such as vitamin A, vitamin D and iron, but the content of cholesterol and purine is also high, which is not suitable for gout patients.
Fish liver is connected with fish gall. Don't break the fish gall when cleaning the fish liver. Liver has the function of detoxification, especially easy to accumulate toxins. Before eating, it should be determined that fish are not polluted by the environment.
Fish sausage has low fat content and no less protein content than fish. However, the sausage of large fish has edible value. Before eating, the dirty things inside should be removed.
