First, look at the appearance, the genuine Ejiao is brown or brown-black, with a flat shape, a smooth and shiny surface and translucent edges; Fake Ejiao is usually dark, dull, uneven and even concave;
The second is to break it by hand. Authentic Ejiao is brittle and hard, does not bend when broken, is easy to break, and has no pores in the section; False donkey-hide gelatin is not brittle, easy to bend, not easy to break, sticky after breaking, and sometimes there are small holes in the section;
The third is the smell. Authentic Ejiao has a faint smell of soybean oil, which is fragrant and slightly sweet to the touch, while fake Ejiao has a strong fishy smell.
In addition, there is a little trick. After mashing Ejiao, put it into a cup and add some boiling water. Then cover it and leave it for a few minutes before opening it. The genuine liquid is clear, while the fake donkey-hide gelatin is turbid and even emulsion-like.
