Ejiao is as yellow as amber and as light as dark. Real people have no skin odor, and they are neither wet nor soft in summer. Fire test: put a few samples into the crucible to burn, which will burst at first, then expand and melt, giving off white smoke with strong fragrance of sesame oil. After ashing, the residue is dark black, loose, flaky or massive, and does not stick to the crucible; Test water: Boil and dissolve, the solution is light brown-red, turbid, with white material precipitation and oil droplets on the liquid surface. Dissolve the glue in water, and the liquid is clear without turbidity; Clap your hands: Clap the table with your hands. If the fragment is brown, translucent and free of foreign objects, it is true. If it is soft but not broken, it is suspected to be counterfeit.

The first fake of Ejiao is Niu Pijiao, which is hard and not easy to break. There is a strong smell when burning, and there is no oil drop on the surface of the test water. The second is miscellaneous leather glue, which smells like soybean oil when burned, and the test water is dark gray-brown red with a small amount of oil spots on the liquid surface; Third, bone glue, the surface is opaque, dull, with small holes caused by bubbles, irregular wrinkles on the side, hard and not easy to break, and slightly smelly; The fourth kind is gelatin, which is smooth and bright, crisp, slightly gassy or smells like ink. After fire test, it becomes white flake powder and does not stick.

In addition, the donkey-hide gelatin solution does not agglutinate after standing for 4 hours, and the fake medicine solution condenses into paste.

In addition, the appearance of turtle glue and deer glue is similar to that of donkey-hide gelatin, which should also be identified: turtle glue, with a brown surface and a slightly green surface, has a yellow "oily head" on it, which is as clean as amber and is not easy to ignite; Deer glue, dark brown surface, translucent to light yellow, single-sided yellow-white porous thin layer, crisp and crisp, reddish brown cross section, glass luster.

Question 2: How to tell the truth of Ejiao cake? The quality of Ejiao cake can be felt by tasting. A good donkey-hide gelatin cake has a gelatinous taste, while a bad donkey-hide gelatin cake has a fishy smell and a poor taste. There is also the simplest way, that is, put the Ejiao cake in warm water and melt it without impurities. It won't melt for a long time, and now it's fake. After all, it's food. Be careful!

Question 3: How to tell the true and false Ejiao cakes? The first trick: recognize the brand.

Li Shizhen's Compendium of Materia Medica records: "Ejiao is the top grade of this classic, and Hongjing says,' Ejiao was named after it went out of East Asia'". It can be seen that Ejiao is the most authentic one produced in Dong 'e County, Shandong Province.

At present, there are many brands of Ejiao on the market. To buy Ejiao, you must choose products produced by big brands, large enterprises and listed companies. Ejiao, like other drugs, is a special commodity, and the registered trademark must be indicated on the package.

The second trick: look at the packaging.

Authentic Ejiao packaging has been professionally designed, with clear patterns and logo lines and exquisite printing, and the word "Ejiao" has obvious concave and convex feeling. Tear the package at one time and tear it along the fold line on the left side of the front of the package, and you can see a set of 16 digits of anti-counterfeiting numbers. According to the instructions, you can know the authenticity by calling, writing short messages or searching online, and entering numbers according to the prompts. Generally, the outer packaging of fake Ejiao is roughly printed, and there are often typos, missing words and registered trademarks. Some fake Ejiao also have anti-counterfeiting labels, but almost all anti-counterfeiting phones can't get through or prompt for input errors. True and false Ejiao put together, at a glance.

The third measure: look at the product.

Authentic Ejiao is a regular rectangle with uniform size and thickness, smooth and bright surface, uniform color, product name printed on the front, correct and clear font, and dark red; There are two regular parting ways on the back of the rubber block, which are hard and brittle and can be broken by hand with a little force; If you pat the rubber block on a hard object, it will break into several pieces, with bright cross section, brown translucent to light irradiation, and no oil holes and air holes; Fake Ejiao is generally black or obviously yellow in color, with irregular rubber blocks, rough and dull surface and different sizes and thicknesses. The front product name is printed with paint and pigment, and the text is mostly bright red, with blurred and skewed handwriting and cracks in the text. There is no dividing line on the back, and those with dividing lines are irregular. Most of them are hard but not brittle, some of them are elastic and not easy to break, and they are not easy to break when flapping. The cross section is gray-black, not bright, easy to soft bond, and there are oil holes and air holes.

The fourth measure: smell the smell

When the genuine rubber block is just opened, take a breath on the surface of the rubber block, and the nose smells like the faint fragrance of Ejiao. After crushing, the nose smells of Ejiao. The fake donkey-hide gelatin has no obvious fragrance, but has fishy smell or strange smell.

Step 5: Observe the solution.

After mashing the genuine rubber block, put it into a proper amount of transparent glass, add a proper amount of boiling water, stir and dissolve it, and let it stand for 1 ~ 2 minutes. There is no visible granular foreign body in the glue solution, which smells slightly unique and has no peculiar smell. False donkey-hide gelatin aqueous solution has obvious fishy smell or peculiar smell, and some of them will have insoluble flocs. After dissolution, obvious granular foreign bodies are common in the glue solution.

First, look at the appearance: the genuine product is a rectangular block, the color is as bright as amber, the surface is smooth with longitudinal coarse stripes, the surface is smooth and shiny, and the edges are translucent; Fakes have different shapes and specifications, dark black or blood red, dull, uneven surface and even concave holes.

The second is to break it by hand: genuine Ejiao is brittle and hard, it will not bend when breaking, and it is easy to break, and there is no air hole in the section; False donkey-hide gelatin is not brittle, easy to bend, not easy to break, sticky in cross section, and sometimes has small holes.

The third is the smell: authentic Ejiao smells like glue, while fake Ejiao smells like fishy smell. Or put a small piece of Ejiao in a hot water cup and cover it for two minutes, and the Ejiao in the cup will smell like glue, tasteless or fishy.

Question 4: It's difficult to tell whether the Ejiao cake is true or false. General glue paste includes donkey-hide gelatin, walnut, sesame, jujube, medlar and yellow wine, that's all. All of them are ground into powder, mixed into blocks, steamed in a pot, and then the finished product is paste.

In terms of color, the black color of the finished paste is heavier, indicating that Ejiao is sufficient. If it is yellow, it means that there is less donkey-hide gelatin. In the normal paste, there should be some walnut blocks that have not been pulverized, so it can be judged that the walnut material is used. In terms of taste, the taste of yellow rice wine is different from others, which can be distinguished by nose, but it is impossible to accurately distinguish whether it is a good yellow rice wine.

In short, the glue paste sold in the market now will not put enough Ejiao, otherwise the price per catty will be around 200. If there is an incomplete explanation, check it yourself.
