How to distinguish real donkey-hide gelatin from fake donkey-hide gelatin? What's the difference between them? Great gods, help!

On June 6th, 2065438+00, CCTV revealed that some small enterprises made fake and shoddy Ejiao by passing off cowhide, horse skin and other scraps as donkey skins. The harmful substances such as heavy metals in this fake donkey-hide gelatin exceed the national pharmacopoeia standard by more than ten times. If you take this product, it will not only have no nourishing effect of Ejiao, but also cause great harm to human health. How to identify the authenticity of Ejiao has become a problem that consumers pay close attention to. According to the expert's opinion, summarize five tricks to identify the authenticity of Ejiao, so that the fake Ejiao has nowhere to hide. The first trick: to recognize the brand Li Shizhen's Compendium of Materia Medica records: "Ejiao is a classic top grade, and Hongjing said,' Ejiao was named after it came 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 state-controlled listed companies. Ejiao, like other drugs, is a special commodity, including registered trademarks, manufacturers, sites, approval numbers, functional indications, etc. It must be marked on the package. At present, "Dong 'e Ejiao" is the most popular and has the best quality. The second trick: look at the packaging of genuine Ejiao. The outer packaging is professionally designed, with clear patterns and logo lines and exquisite printing. The name "Ejiao" has obvious concave-convex feeling. Fake Ejiao generally has rough outer packaging printing, and typos, missing words and typos often appear on registered trademarks. If you really put Ejiao together, it will be clear at a glance. The third measure: check the authenticity of genuine Ejiao. The package is torn at one time, along the zigzag line on the left side of the front. You can see a set of 16 security numbers. According to the instructions, you can know the authenticity by making a phone call, writing a short message or searching online. Some packaging boxes are affixed with round anti-counterfeiting labels, and the silver-gray coating in the middle of the labels can be scraped off, and the labels can be dialed by phone or SMS. Fake Ejiao packaging is generally not a one-time tear package. Although there are anti-counterfeiting signs, almost all anti-counterfeiting phones can't get through or prompt for input errors. The fourth measure: look at the product. The real Ejiao is a regular rectangle with uniform size and thickness, smooth and bright surface and uniform color. The product name is printed on the front, and the font is correct and clear, which is deep 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 the rubber block is slapped hard on a hard object, it will break into several pieces with bright cross section and no oil holes or air holes; Fake Ejiao is generally black or obviously yellow in color, with irregular rubber blocks, different sizes and thicknesses, rough and dull surface, and the product name on the front is printed with paint and pigment, with bright red characters, blurred and skewed handwriting and cracked characters; 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 grayish black and not bright, with oil holes and air holes. The fifth measure: smell the genuine rubber block and open the package. Breathe on the surface of rubber block. The nose smells a faint scent of Ejiao. After the pieces of donkey-hide gelatin are crushed, the nose smells the unique fragrance of donkey-hide gelatin. The fake donkey-hide gelatin has no obvious fragrance, but has fishy smell or strange smell.
