商家认为吃鱼除了选鱼有讲究，吃鱼也有讲究，鱼身上有不少地方易被忽视，这五个宝贝千万别扔！

　　Businessmen believe that there are not only exquisite fish selection, but also exquisite fish eating. There are many places on the fish that are easy to be ignored. Don't throw these five treasures away! uuuuuuuuuu

　　吃鱼前，必不可少的是刮鳞、开膛等步骤。这个过程看似简单，却藏着不少学问，有些人可能扔掉了鱼身上的很多宝贝。

　　Before eating fish, scaling, opening and other steps are indispensable. This process seems simple, but there is a lot of knowledge hidden. Some people may throw away a lot of treasures from fish.

　　鱼鳞

　　Scale

　　鱼鳞是鱼的外骨骼，富含胶原蛋白、钙、磷、卵磷脂等营养物质，同时还含有甲壳素这种膳食纤维。

　　Fish scale is the exoskeleton of fish, rich in collagen, calcium, phosphorus, lecithin and other nutrients, but also contains the dietary fiber of chitin.

　　因为胶原蛋白会在70℃~90℃的温度下转化为可溶性的明胶，常见的吃法是将其制成鱼鳞冻。

　　Collagen can be converted into soluble gelatin at 70 ~90 ~C. The common way to eat it is to make fish scale jelly.

　　具体方法是：将鱼鳞刮下，洗净。下入放满水的锅中，加点醋，使水温保 持在70℃~90℃的将沸未沸状态，小火慢炖。等鱼鳞慢慢融化，汤汁黏稠之后，关火，将其晾凉，置于冰箱冷藏成冻。食用时，将鱼鳞冻拌入调料即可。 鱼骨

　　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

　　鱼骨也就是我们常说的鱼刺，富含钙等微量元素，经过软化处理后，其营养成分会更容易被人体吸收。

　　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.

　　非常小的带骨小鱼要使劲嚼碎，进入胃里后，胃酸会将其鱼骨部分软化，促进钙、磷等营养物质的溶出。大鱼骨要吸它的骨髓，也就是鱼脊柱中的白线。

　　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.

　　此外，鱼骨还可 以加醋熬汤，小火焖煮(2~4小时)。需要注意的是，用白水煮汤，鱼刺很难变软，多加点食醋焖炖，可利用醋酸的作用促进鱼刺软化。

　　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.

　　鱼鳔

　　Air bladder

　　古代有“海洋人参”之称，与燕窝、鱼翅齐名。鱼鳔含有生物大分子胶原蛋白质，有改善组织营养状况，促进生长发育，延缓皮肤衰老的效能，是理想的高蛋白低脂肪食品。海水鱼的鱼鳔壁较厚，通常制成干品，称为鱼肚。

　　In ancient times, it was called "Sea Ginseng", which is as famous as bird's nest and shark's fin. Fish bladder contains bio-macromolecule collagen protein, which can improve the nutritional status of tissues, promote growth and development, and delay skin aging. 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.

　　鱼肚制成的菜肴口感滑润、细腻，有浓厚感。鱼 鳔里含有丰富的胶原蛋白和欧米伽3不饱和脂肪酸，可能对血脂控制有益。常见的做法是：将鱼鳔用清水洗净，和鱼一起清炖或红烧。
 

　　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.

　　鱼肝

　　Fish liver

　　鱼肝是鱼身体里储存多种营养素的地方，比如，维生素A、维生素D和铁等微量营养素，但其中的胆固醇和嘌呤含量也很高，不适合痛风患者。

　　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.

　　鱼肝和鱼胆相连，在清洗鱼肝时，别把鱼胆弄破。肝脏有的功能，特别容易集聚毒素。食用前，应确定鱼没有受到环境污染。

　　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.

　　鱼肠

　　Fish intestine

　　鱼肠含脂肪低，蛋白质含量不逊色于鱼肉。不过体积大的鱼的鱼肠才有食用价值，食用前要把里面的脏东西去净。

　　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.

　　因为鱼类所吃的食物都要经过鱼肠消化，所以它是鱼的身体里受污染程度比较重的器官。如果对鱼的养殖环境不够放心，就不建议吃

　　Because the food eaten by fish is digested through the intestine, it is a heavily contaminated organ in the body of fish. If you are not reassured about the aquaculture environment, you are not advised to eat it.
