Which parts of the fish body are processed into isinglass?

We all know that fish glue is a tonic, just like donkey-hide gelatin and royal jelly. It not only beautifies the skin, but is also rich in collagen. Poor skin, pigmentation, frequent acne, and inflammation on the skin surface can all be nourished and repaired with donkey-hide gelatin. There is a layer of fat on the belly of the fish, which is fish glue. The fish glue is cleaned after glass processing and becomes transparent and gelatinous. The finished product fish glue tastes similar to bird's nest, is very viscous, and has high nutritional value.

① Gelatin

Fish glue that looks like gold

Made from the skin and scales left over from fish fillet production without the viscera, blood, meat, etc. The raw materials are washed, soaked in lime water, acidified to remove calcium phosphate in fish scales, rinsed, neutralized, gelled, filtered, frozen, sliced ​​and dried. Gelatin has high purity, high transparency and viscosity, and strong freezing power. It is mainly used to manufacture culture media, plates, photographic films, etc., and can also be used in the food industry.

② Rough rubber

The crude gelatinous materials such as heads, tails, bones, etc. mixed with blood, meat, and internal organs are cleaned, heated with steam in a pressure cooker, and then separated by filter pressing or high-speed centrifugation to remove impurities and fish oil. After that, they are evaporated and concentrated to a concentration of 50%, and preservatives and spices are added. It does not freeze at room temperature and is easy to use. It is an adhesive for wood, leather, etc., and is also a powder adhesive in the manufacture of matches and grinding wheels.

③ Fish bladder glue

After the fish maw is washed with water to remove mucus and blood, the inner and outer membranes are peeled off. The larger and thicker ones are dried separately into sheets of glue; the smaller and thinner ones are stacked together and rolled into a round or strip shape, which is called round glue or strip glue after drying. It is slightly yellow, translucent, strong and has a slight fishy smell. It is used as a clarifier for beverages such as beer and a thickener for juices and jams. In addition, high-quality yellow croaker fillet glue, also known as fish maw, is a traditional marine delicacy. Yellow lip fish maw is a precious tonic. Isinglass is used as a clarifier for alcoholic beverages and has long been used to clarify beer, increase its freshness, and correspondingly improve its freezing stability. It also has a certain effect on shortening the ripening cycle.

effect

From the perspective of traditional Chinese medicine, fish maw has a very nourishing and therapeutic effect. [1] It is made from dried fish maws. It is usually made from giant sturgeons and large yellow croakers. Because the fish maws are processed according to the different types of fish, the hardness of the fish maws also varies. Fish maws can be divided into three types: wide maw, fish maw and fried maw. The price ranges from a few hundred yuan per catty [2] to several thousand yuan. Fish maw has been one of the "Eight Delicacies of the Sea" since ancient times. After nutritional analysis, the mystery of the "treasure" of fish maw has been solved, just like the "Da Vinci Code".

Because fish maw contains a large amount of collagen protein and is easy to absorb and utilize, it is very popular among people. The fish maws available on the market now are mostly from croaker and large fish maws from the deep sea, commonly known as "reckless maws", which are all made from fish that are extremely rich in gelatin. These fish maws are extremely rich in protein, vitamins, minerals and other essential elements for the human body.

Fish maw can enhance the digestion and absorption function of the gastrointestinal tract, improve appetite, and help prevent and treat symptoms such as loss of appetite, indigestion, and constipation; it can enhance the toughness and elasticity of muscle tissue, enhance physical strength, and eliminate fatigue; it can strengthen brain nerve function, promote growth and development, improve thinking and intelligence, and maintain normal glandular secretion; it can prevent and treat slow reaction, maldevelopment in children, insufficient milk secretion in postpartum women, forgetfulness and insomnia in the elderly, etc. Since fish maw contains a large amount of glue, it has the effects of promoting blood circulation, replenishing blood, stopping bleeding, keeping out cold and removing dampness, so it can improve immunity. It is more suitable as a tonic for people with weak constitution, true yin deficiency, and mental overwork.

In addition, fish maw is the best choice for women to supplement collagen. 70% of the protein in human skin is collagen. The network structure it forms supports the skin, making it look smooth, plump, soft and elastic. As we age, the rate of collagen loss in skin tissue gradually exceeds the rate of production, so the skin loses elasticity, becomes thinner and aged, and becomes sagging, wrinkled, and dry. Therefore, timely supplementation of collagen can restore the skin's youthful vitality.

Specific method of isinglass soaking

1. Generally, fish maw is soaked in hot water.

2. Put the fish maw in boiling water for about 20 minutes, turn off the heat and bake until the water is warm. Take it out and soak it in cold water. Change the water every day (avoid getting it contaminated with fat or oil).

3. Fish maw is made of very heavy gelatin and easily sticks to the bottom of the pot. When boiling, it is advisable to use a bamboo mat as the bottom to prevent it from burning.

4. When cooking, add ginger, onion, oil, salt and liquor to a wok, add water and wait for the water to boil. Put the fish maw into the boiling water and boil for about 15 minutes to remove the fishy smell.

5. The fish maw will gradually dissolve if it is cooked for a long time.

6. To make the fish maw delicious, first boil the soup, then add the fish maw and cook for about 20 minutes.

Note: Generally, isinglass does not need to be soaked. You can put it directly into the ceramic soup pot and cook together! This saves the soaking time. Generally, the whole pot is placed in a hot water bath, and the stewed isinglass does not stick to the pot at all. It can also be stewed with chicken, and the soup will be more delicious!
