How to distinguish the quality of Ejiao?

How does Ejiao distinguish between good and bad?

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.

How to tell the quality of Ejiao?

Judge the quality of Ejiao, 1. Smell it, it has a faint fragrance. 2. Look at the color, it's black and shiny. 3. Hardness, good Ejiao is hard and brittle at room temperature, and poor Ejiao is soft at room temperature. This is what I heard from my friend at the drugstore. I am interested in Chinese medicine, but I have no chance to go to Chinese medicine school. It is a pity.

Is there a difference between genuine Ejiao and inferior Ejiao?

One: How to distinguish the quality of Ejiao (a piece)

Look:

Authentic Ejiao is an amber or brown-black rectangular flat block with smooth appearance, neat corners and shiny surface. When viewed through light, the edge of Ejiao block is translucent.

2. Broken:

Ejiao is a rubber block made of donkey skin, which is brittle and can be broken with a light pat. Small pieces of Ejiao will dissolve in hot water within half an hour. Gelatin dissolved in hot water will form jelly once it is refrigerated.

3. 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 it has fishy smell or strange smell.

4. Taste:

The donkey-hide gelatin block is contained in the mouth, which will give off a gum fragrance when it is slightly sweet, while the fake donkey-hide gelatin tastes salty and has obvious fishy smell.

Do you know why inferior Ejiao stinks? Because it is made of the rotten skins of purchased dead pigs and cows, and the black-hearted workshop is made of the leftovers of leather shoes, it not only stinks, but also the rotten skins are more harmful to the body.

How to distinguish the quality of Ejiao?

First look at the packaging. The outer packaging of genuine Ejiao is printed clearly and beautifully, and the name and logo are concave and convex, with anti-counterfeiting signs on the outside. The outer packaging of fake donkey-hide gelatin is rough in printing, the font strokes are vague and rough, there is no anti-counterfeiting mark, typos and missing words often appear, and the production batch number is often wrong. The second is to check the products. First of all, it depends on the nature of the rubber block. Authentic Ejiao is a regular rectangle, uniform in size and thickness, square and flat, smooth and bright in surface, uniform in color and brown, "color like amber, black as paint". Fake goods are generally black, with irregular rubber blocks with peculiar smell, rough and dull surface, different sizes and weights of rubber blocks, and oil and gas holes. Secondly, it depends on the product name on the rubber block. Authentic Ejiao rubber blocks are printed with medical iron oxide red, and the handwriting is correct and clear, showing dark red, while counterfeit products are generally printed with paint and other things, and the handwriting is blurred, the font is skewed, there is no indentation, and it is easy to fade or erase. Third, look at the light transmission. Authentic Ejiao is translucent amber or brown under light perspective, while counterfeit Ejiao is dark or opaque under light perspective. Fourth, look at the texture. Authentic gum Arabic is hard and brittle. If you break it by hand, it will break without bending. If you pat the rubber block on a hard object in your hand, it will break into several pieces, with a bright cross section and no oil holes, air holes and obvious knife marks. The fake glue is hard but not brittle, elastic and not easy to break, and it is not easy to break when flapping. The cross section is gray-black, dull and easy to stick. The third is to smell. Gently rubbing on the rubber block, the genuine Ejiao has obvious fragrance, and the fake has bad smell. Mashed genuine colla corii asini, put it into a cup, add appropriate amount of boiling water, immediately cover the cup, let it stand for 1 ~ 2 minutes, and gently open it. The glue solution is clear, with no visible granular foreign bodies, a faint smell of soybean oil and colla corii asini, sweet and salty, fragrant and no peculiar smell. Fakes are not easy to dissolve, and some have insoluble flocs. After melting, the glue solution is turbid, and there are often granular foreign bodies visible to the naked eye, and the aqueous solution has a pungent fishy smell.

Now fake donkey-hide gelatin and poisonous donkey-hide gelatin not only have no effect, but also do great harm to the body. Such reports are endless! Let's talk about how to distinguish real Ejiao.

Hard and brittle, easy to break, with neat section, a little fishy smell and soybean oil taste, slightly sweet;

As for auxiliary materials, various dried fruits (raisins and blueberries) and traditional nourishing ingredients (Lycium barbarum, longan, rose and ginseng) can be added according to taste and efficacy requirements.

Ejiao cake is not only unique in production method, but also very particular in material selection. The first is Ejiao, just like Maotai. Only the ancient well water of authentic origin can make the best donkey-hide gelatin. But there are hundreds of large and small manufacturers in Dong 'e Town and Dong 'e County. Therefore, consumers should pay attention to identify whether it is a regular manufacturer. Secondly, it is necessary to recognize the OTC quasi-font mark of traditional Chinese medicine, and suggest consumers to go to regular pharmacies or large supermarkets to avoid being deceived by fake and shoddy products. Finally, it can be identified intuitively from the appearance of the donkey-hide gelatin block. Regular donkey-hide gelatin blocks are rectangular, dark brown, smooth in surface, without oil and gas holes, shiny, hard and brittle, bright in section, brown in fragments and translucent to light. If the donkey-hide gelatin block is found to have oil holes, dull color and uneven surface, then consumers must be vigilant.
