CATDOLL : CATDOLL: How nutritious is hairtail?

Hairtail is a fish that we are familiar with, and almost every household can cook it. Whether it is braised, fried, sweet and sour or steamed, it is very suitable for cooking hairtail, which is fresh, fragrant, tender and delicious.

However, there is a big misunderstanding about hairtail that many people don’t know, and that is its "fish scales".

This layer of scales is closely related to the nutritional value of hairtail fish, and can even be said to be the most valuable part of the hairtail fish. If you don't understand it and handle the hairtail fish carelessly, the nutritional value of the hairtail fish will be lost by more than half! What a pity!

There is a layer of silver substance on the surface of hairtail. Many people may think that this is fish scales, but in fact this layer of substance is called "silver fat".

The nutritional value of silver fat is very high, and it is the most valuable part of the hairtail fish.

The most precious nutrient in silver fat is called 6-thioguanine, which is a pure natural anti-cancer substance that can assist in the prevention and treatment of serious diseases such as leukemia and gastric cancer. 6-thioguanine can be found in many current anti-cancer drugs.

In addition, silver fat is rich in lecithin, which can reduce cell mortality and delay brain aging. It is Youshu Mingxiu’s natural "brain gold".

Silver fat has such high nutritional value that when we clean hairtail, we must be careful to protect it and not wash it off, otherwise it would be a waste.

Therefore, when washing hairtail, you must remember to wash it with cold water. Because silver fat is very afraid of heat, if you wash hairtail with hot water, the silver fat will melt.

However, if the hairtail fish is not fresh, the silver fat on the surface will turn yellow and produce an odor. In this case, you need to wash the hairtail fish with hot water to clean all the silver fat on the surface.

In addition to silver fat, the meat of hairtail also has high nutritional value, mainly reflected in unsaturated fatty acids, selenium, magnesium, iodine and other trace elements.

Selenium is a trace element with antioxidant properties and has a protective effect on the liver. Taking a certain amount of selenium every day can help prevent liver cancer.

Magnesium is a "good friend" of the cardiovascular system. Adequate intake of magnesium has a relatively good preventive effect on cardiovascular and cerebrovascular diseases such as hypertension, myocardial infarction, and atherosclerosis.

In addition to maintaining the normal function of the thyroid gland, iodine can also promote the body's metabolism.

In general, the nutritional value of hairtail is relatively high, especially the silver fat on its surface. Therefore, when we clean hairtail, we must pay attention to retaining the silver fat, which is the most beneficial to health.

The protein content of hairtail is close to that of pork, and it also contains minerals such as calcium, phosphorus, iron, iodine, etc. Hairtail can improve blood deficiency and weak spleen and stomach.

The magnesium in hairtail has a good effect on the cardiovascular system. Unsaturated fat can lower cholesterol levels. The oil in hairtail contains anti-cancer ingredients.

Fresh hairtail is silvery white and shiny. If the surface has lost its luster or turned yellow, it means it is no longer fresh. Hairtail has a high fat content and is best cooked in cold water.

Cleaning hairtail is usually done with cold water, such as rice water, to reduce the fishy smell. It is recommended not to use hot water when cooking, also to reduce the fishy smell.

Hairtail fish is tender and has no small bones, making it very easy to eat. There are many suitable cooking methods, and it can also be made into canned food, pickled fish, etc.

Here's a dish to share with you: yuba stewed fish soup

Hairtail, known as one of China's four major seafoods along with large yellow croaker, small yellow croaker and squid, is a fish that often appears on our tables and can be said to be one of the most common and delicious marine fish.

So how nutritious is this delicious dish?

Let’s take a look with Brother Chao below!

Compared with freshwater fish, hairtail can indeed be regarded as a kind of fish containing high-quality protein and polyunsaturated fatty acids. However, as a seafood, compared with other marine fish, its nutritional value is not outstanding overall.

【Brief introduction of hairtail】

Hairtail, also known as toothfish, ribbonfish, etc., belongs to the class of bony fish, order of Perciformes, family of ribbonfish. It is named for its laterally flattened, ribbon-like body and long, whip-like tail. Hairtail meat is tender, fat, and delicious. Apart from a large bone in the middle, it has almost no small thorns, making it very convenient to eat and is very popular among people. [1]

【Nutrition of Hairtail】

To determine the nutritional value of hairtail, we first need to look at the basic nutrients it contains.

As a seafood, the protein content of hairtail is not much different from that of other fish. Compared with poultry protein, its protein is delicate and tender, more conducive to human digestion and absorption, and helpful for the development and growth of children and adolescents. There are 14 kinds of free amino acids in hairtail muscle, with a total score of 9.88 g/kg, mainly lysine, histidine and alanine, with mass fractions of 1.02, 0.35 and 0.28 g/kg respectively. In addition, according to the determination, there are 23 kinds of fatty acid composition in hairtail, and different from the fatty acid composition of poultry, hairtail fatty acids are mostly unsaturated fatty acids mainly composed of DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid), accounting for 60.57% of the total fatty acid mass, which is very helpful for lowering blood lipids and cholesterol, and has a certain effect on preventing dyslipidemia and cardiovascular diseases.

In addition, DHA and EPA are two main polyunsaturated fatty acids in the fatty acid composition of hairtail. Polyunsaturated fatty acids are essential fatty acids for the human body. The human body cannot synthesize them on its own but they are indispensable and must be obtained through food intake. And according to a large number of studies, DHA has a certain positive effect on human brain development and vision development. [2]

However, we cannot easily determine the nutritional value of hairtail based on these alone. Let's take a look at a table to have a more intuitive understanding of the nutrition of hairtail.

[Comparison between hairtail and other meats]

Based on the above information and tables, we can further determine:

Compared with freshwater fish, hairtail can indeed be regarded as a kind of fish containing high-quality protein and polyunsaturated fatty acids. However, as a seafood, compared with other marine fish, its nutritional value is not outstanding overall.

【Summarize】

Hairtail is a common seafood in daily life. Although delicious, its nutritional value is not outstanding among marine fish.

Hairtail is one of the four major economic fish species in my country, accounting for about 75% of the total marine fish products. It is also known as hairtail, green hairtail, scaled knife fish, sea knife fish, and tooth hairtail. It is a warm-water pelagic fish distributed in the Yellow Sea, Bohai Sea and South my country Sea.

Hairtail fish is tender, thick and has few bones. It is rich in nutrition. It is not only rich in protein and contains all 8 essential amino acids, but also extremely rich in essential fatty acids and vitamins A and D. Hairtail fish contains 7.4 grams of fat per 100 grams, which is higher than the content of ordinary fish, but it contains more unsaturated fatty acids and has a longer carbon chain of fatty acids, so it has the effect of lowering cholesterol. The protein contained in hairtail fish meat is comparable to that of pork, beef and mutton, with a content of 18.1 grams per 100 grams, which is higher than that of ordinary fish, especially 5 times more than that of large yellow croaker. It also contains essential trace elements such as calcium, phosphorus, iron, iodine and various vitamins, which are easier to digest and absorb than other meats. It can be called an ideal tonic for the elderly, children, pregnant women and parturients.

Traditional Chinese medicine believes that hairtail is sweet, warm in nature, and can nourish the five internal organs. The classical medical book "Compendium of Materia Medica" states that hairtail is "sweet and warm, nourishes the five internal organs, and kills insects", and "Food Taboos" says that it "harmony the stomach and stimulates appetite"; the famous Qing Dynasty nutrition book "Sui Xi Ju Diet" believes that hairtail has the effects of "warming the stomach, nourishing the body, and moisturizing the skin". It can be used as a tonic food therapy for those who have been ill for a long time, have insufficient qi and blood, eat less and become thin, have dry skin, and are short of breath and weak. There is a folk prescription for treating hepatitis: steam fresh hairtail and eat the upper layer of oil, unlimited, and it can improve symptoms.

It is worth mentioning that the silvery-white layer covering the hairtail is a layer of oil, which contains a variety of unsaturated fatty acids. Animal experiments have shown that the silvery-white oil of hairtail can significantly reduce the cholesterol in the blood of rats. Researchers also unexpectedly found in the experiment that the fur of rats fed with silvery-white hairtail oil grew particularly well. Someone fed this fish oil to a child with dull and yellow hair, and after a month, the child's hair turned completely black. In recent years, scientists have also discovered that the silvery-white oil layer of hairtail contains a cancer-killing ingredient 6-thioguanine, which can effectively treat acute leukemia and other cancers. It is not advisable to eat too much hairtail at one time, especially those with skin diseases such as scabies, eczema or skin allergies should be more cautious.

When eating hairtail, there is no need to scrape off the silvery white "fish scales". Common methods are steaming, braising and frying. Here is a recipe for a famous dish called "Dry Fried Hairtail": Cut the cleaned hairtail into 5 cm segments, add seasoning, scallion segments and ginger slices to marinate. Mix egg liquid and flour into a porridge-like paste, then add the fish segments and mix well, put them in a frying pan or pan and fry until both sides are golden brown and cooked through. When frying fish, heat the pan first, then cool the pan with cold oil, then add the raw materials, arrange them piece by piece, and fry them over medium heat. Eggs and flour are the protective layer of the raw materials. When they are heated, they can quickly condense into shape, so that the fish does not stick to the pan and maintain the integrity of the fish. The shell of the finished dish is slightly crispy, the method is simple, and it tastes delicious.

Or like this: take out the fried hairtail, leave a proper amount of oil in the pan, heat it up, add chopped green onion, ginger and garlic and stir-fry until fragrant, add the hairtail, then add the sauce made of soy sauce, vinegar, sugar, salt, MSG, cooking wine and water (the ratio of raw materials to sauce is 10:2), stir-fry quickly on high heat, let the sauce wrap the raw materials, and remove from the pan when the sauce is eaten. This method is more suitable for loss of appetite and cancer patients with poor taste.

Hairtail fish is very nutritious and suitable for children of all ages. Be careful to pick out the bones
