What is the raw material of Ejiao?

Question 1: What is the raw material of Ejiao? Dong 'e County, Shandong Province has a long history of boiling Ejiao. By the end of the Qing Dynasty, the glue boiling industry developed rapidly and the glue making technology gradually matured. During the slack season, almost every household in Dong 'e County ignites and cooks glue. They set up a shed and workshop, sat in a big pot and boiled glue with Sang Mu. From raw material processing to boiling, cutting, drying and gluing, more than 50 processes are all completed by hand. There are many mysteries about the influence of raw materials from different seasons and producing areas on the finished rubber, how to make a fire when peeling and boiling rubber at different times, how to grasp the temperature of adding water and the heat of rubber.

Many people know that this kind of donkey-hide gelatin is made of donkey-hide gelatin as the main raw material. Collagen is the main component of Ejiao, which is the most abundant and widely distributed in protein. The unique hydroxylysine of this functional protein is the necessary material basis of human bones and connective tissues. However, the raw material originally used to cook Ejiao is not Ejiao. According to the records of famous doctors in Wei, Jin, Southern and Northern Dynasties, it was made of boiled cowhide, which was regarded as. Why did donkey skin replace cowhide later?

After the Tang and Song Dynasties, wars with cowhide as the main military material frequently occurred, so there was a saying at that time that cowhide was officially banned, that is, civilians were not allowed to fight with cowhide. Some saddle boots and armor are made of cowhide, so cowhide is not allowed. After a slow transition, it was found that donkey skin was better than donkey skin for more than two thousand years. This historical practice has proved that donkey skin is indeed the best, and it is also recorded in ancient books that donkey skin glue is better than other glue.

Generally speaking, you can boil Ejiao as long as you have donkey skin, but why is Ejiao recorded in ancient books the most famous in East Asia? This is not only because the fur produced in the surrounding areas of Dong 'e is black and bright, but also because of its large size and high glue yield. It is not entirely because the local people in East Afghanistan have a tradition of refining Ejiao since ancient times and have mastered the technology of cooking Ejiao. One thing is lacking in many places, which is another main reason why Ejiao is most famous from Dong 'e, and that is DD water. What's the difference between the local water in East Afghanistan and the water in other places? Regarding the water in Dong 'e, Li Daoyuan's Notes on Water Classics recorded that "Dong 'e has a well as big as a wheel, and at the age of twenty, he often boiled glue to pay tribute to Tianfu". It is considered that Dong 'e groundwater is the subsurface flow of Jihe River in Jiyuan County, Henan Province, and the water is filtered through underground rocks and gravel layers.

The groundwater in Dong 'e is different from others, and its relative density is 1.0038 1.0038, which can be said to be much heavier than other waters. If you think that pure water is 1 and other water is 1.0 1, then the water in Dong 'e is more than three kilograms heavier than other water.

Let's do an experiment. The water in this cup comes from the underground water 300 meters underground in Dong 'e, but if we put a coin on the water, it can float, but on the water filled with pure water, no matter how carefully the staff places it, it can't float. Why can coins float in the local groundwater in Dong 'e?

Why this kind of water is heavy is mainly because it contains a lot of mineral elements and trace elements, which makes this kind of water relatively dense. What good is this water for cooking gelatin? It is beneficial to the separation of impurities in the boiling process, because the boiling process is the separation process of collagen and non-collagen We have also done experiments in this field. Boiling gelatin with pure water is a complete mess.

In fact, as early as Li Shizhen's Compendium of Materia Medica, the benefits of boiling Ejiao with Dong 'e water were elaborated in detail. "Its water is clear and heavy, and its sex tends to decline, so it can cure the turbid phlegm of the upper flush." In the past, people only thought that Ejiao produced in Dong 'e was more effective than that produced in other places according to clinical practice, but it was difficult to explain why. Today, after scientific detection of local groundwater, we have the answer.

Question 2: What material is Ejiao made of? It is also called jar-covering glue and donkey skin glue. It is a rubber block made of donkey skin. The preparation method is as follows: firstly, the donkey skin is scraped clean, cut into small pieces, boiled in water for 3 days and nights, and when the juice is thick, the donkey skin pieces are taken out and boiled in water. Identification method of Ejiao: Ejiao is also called donkey skin glue. A rubber block made of the unhairing skin of a horse and donkey. Ejiao is a special medicine. Fried donkey-hide gelatin with clam powder can improve the efficacy of clearing away heat, moistening lung, resolving phlegm and resolving hard mass. Fried Colla Corii Asini with Pollen Typhae can enhance the effect of enriching blood. Drug identification: Ejiao is a neat square block, generally about 3 cm long, 3 cm wide and 0.5~0.7 cm thick. The surface is brownish black or brownish red, smooth and shiny, with weak breath and slightly sweet taste. Transparent to light, hard and fragile, with the same color as the surface. After summer, it is best to be dry, brown, bright, transparent, tasteless and not soft. Experience identification: ① transparent to light, pure and free of impurities, such as amber dark brown or brown. (2) It is true that it is hard and fragile, and the section has a brown glass-like luster. (3) The smell is weak, the taste is slightly sweet, and there is no fishy smell to the genuine product.

Question 3: Who knows what raw materials Dong 'e Ejiao is made of? Colla Corii Asini, Ginseng and Velvet Antler are also called "Three Treasures of Traditional Chinese Medicine", which is a kind of precious traditional Chinese medicine. Also known as donkey hide glue and adhesive. The effect of enriching blood and strengthening the body is obvious, and it is known as the "holy medicine" for enriching blood. It has been a treasure of Gongyuan since the Northern Wei Dynasty or earlier. 1 place of origin and place of origin 1. 1 place of origin is a rubber block made of donkey skin by unhairing and boiling. A long time ago, our ancestors discovered that the juice of hides cooked for a long time could be concentrated into a sticky substance, which was used to stick things, and it was difficult to break after drying, so they found this substance "glue". People can strengthen their physical strength after eating chewing gum, which has become a medicine for treating some diseases. The medicinal use of Ejiao was first seen in the ancient medical book "Fifty-two Diseases" unearthed from Mawangdui Han Tomb. Shennong's Classic of Materia Medica listed it as the top grade, which has been discussed in all previous dynasties. Ming's Compendium of Materia Medica described in detail: "Ejiao is a holy medicine for treating hematemesis, epistaxis, bloody stranguria, hematuria, diarrhea due to intestinal wind, bloody pain and dryness in women, irregular menstruation, childlessness, leucorrhea, prenatal and postpartum diseases." Before the Tang Dynasty, the raw material of Ejiao was mainly cowhide, and pigs, donkeys and horses all used cowhide. In the Song Dynasty, it changed from cowhide to donkey skin. Compendium of Materia Medica calls Ejiao "Ejiao" and Niu Pijiao "Gelatin", which are clearly divided into two drugs. Donkey skin is used as "Ejiao" in China Pharmacopoeia. 1.2 Origin "Ejiao" in Shennong's Classic of Materia Medica in the Western Han Dynasty was produced in Dongping County and boiled with cowhide, which was listed as the top grade in Dong 'e. Liang Shi Tao Hongjing said, "Ejiao got its name from Dong 'e, indicating that Ejiao originated in Dong 'e. About Dong 'e County, it has been more than two thousand years since Qin Dynasty. In the long river of history, Dong 'e Town in Pingyin County and Acheng Town in yanggu county were once the residences of Dong 'e County due to the needs of war, flood and administrative management. Dong 'e County is now established in 1948. Legend has it that langxi River, Twelve Mountains, Liulijing and Ajing related to Ejiao are all distributed in this area. Therefore, from a historical point of view, the origin of Ejiao should be this area. Dong 'e Ejiao Group, the largest Ejiao producer in China, and Dong 'e Town Ejiao Co., Ltd., a Shandong Fujiao Group, are also located here. At present, there are more than 50 Ejiao factories in China, which are produced in Shandong, Hebei, Henan, Beijing, Jilin, Hunan, Anhui, Heilongjiang, Gansu, Inner Mongolia, Liaoning and other provinces, among which Shandong has the largest output, accounting for more than 80% of the total output. Shandong Ejiao is famous for its authentic, exquisite materials and exquisite craftsmanship, and it is also closely related to the local water quality. According to legend, this glue is made by an ancient method. Every spring, select pure black and healthy donkeys, feed them to the grass in Twelve Mountains and drink the water from langxi. Slaughter skins in winter, boil them in a silver pot with well water and langxi river water, stir them with a golden spatula, and add medicinal juices such as Ginseng Radix, Radix Astragali, Radix Angelicae Sinensis, Rhizoma Chuanxiong and Radix Glycyrrhizae. Sang Mu simmered for three days and nights, then condensed and cut into pieces and dried in the shade. According to the investigation, the local water for processing Ejiao contains a certain amount of inorganic ions, which is beneficial to the hydrolysis and impurity removal of protein during the processing. There are too many inorganic ions and high water content, which easily lead to excessive ash content of Ejiao, while the specific gravity is too small to remove impurities. 1980, the production water of colla corii asini in Shandong, Beijing, Tianjin, Shanghai, Zhejiang and other places was tested. It was found that the production water ratio of colla corii asini in Shandong was 1.0028 ~ 1.0065438, and that in other producing areas was 1 ~ 65438. 2. Functions and components of Ejiao 2. 1 Functions of Ejiao is sweet and flat, and enters the lung, liver and kidney meridians, and has the functions of nourishing yin and enriching blood, moistening dryness and stopping bleeding, and preventing miscarriage. Can be used for treating blood deficiency and sallow, dizziness and palpitation, muscle weakness, restlessness, deficiency of internal wind, lung dryness and cough, hemoptysis and hematemesis, hematuria and hematochezia, metrorrhagia, irregular menstruation of women, and missed pregnancy. 2.2 Ingredients of Ejiao 2.2. 1 The basic ingredient of Ejiao is the degradation of procollagen contained in donkey skin. Lu Zixian and others used SDS- polyacrylamide gel electrophoresis to determine the molecular weight of Ejiao from 80,000 to 200,000. After the donkey-hide gelatin was hydrolyzed, more than 18 kinds of amino acids were determined, of which 8 kinds were essential for human body. 2.2.2 Determination of Trace Elements Atomic absorption spectrometry and emission spectrometry show that Ejiao contains 27 kinds of trace elements, 9 of which are essential elements for human body, with high contents of iron, copper, magnesium, zinc and strontium. 2.2.3 Other ingredients Recently, donkey-hide gelatin contains dermatan sulfate. This ingredient is mainly used to treat cardiovascular diseases. At present, some manufacturers have produced this medicine. Pharmacological Effects of Colla Corii Asini 3. 1 Nourishing blood and enriching blood Colla Corii Asini has obvious effects of nourishing blood and enriching blood ...

Question 4: What are the main raw materials of Dong 'e Ejiao? The main raw materials of Dong 'e Ejiao are donkey skin, yellow wine, soybean oil and rock sugar. Its main components are collagen, collagen that can be absorbed by the human body, and some vitamins that the human body cannot produce!

Question 5: What is the raw material of Ejiao? Does anyone know about donkey skin?

Question 6: What is the material of Ejiao? Ejiao is made of donkey skin as the main raw material and boiled with refined water (the glue without refined water is called donkey skin glue, donkey glue). Ejiao originated in Gudong County, Shandong Province, and used ancient well water (ancient well water is in Acheng Town, yanggu county, Shandong Province). The best is amber, transparent and tasteless.
