How to identify genuine and fake Ejiao
Ejiao is a rubber stick made of donkey skin through more than 50 processes, such as decoction and concentration. It has the effects of nourishing blood and yin, moistening dryness and stopping bleeding, and is also called "three treasures of Chinese medicine" with ginseng and velvet antler. In recent years, Ejiao has been widely recognized for its functions of nourishing and beautifying, anti-sub-health and improving immunity. Ejiao is popular all over the country. There are many colla corii asini and fishballs in the market. So how to identify true and false Ejiao?

1. Look at the package.

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.

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 beat the rubber block hard on a hard object, it will break into several pieces, with a bright cross section, brown and 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.

Identify brands

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, with registered trademarks such as "Dong 'e Ejiao", manufacturer, site, approval number, function indication and so on. It must be marked on the package. At present, "Dong 'e Ejiao" is the most popular and has the best quality.

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.

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.
