We can through the following three ways to conduct the first identification.
1. Industrial gelatin products generally poor quality, more impurities, viscosity and toughness is relatively small, so particularly fragile, if found in the products found in these, basically can be judged to be added industrial gelatin.
2. Industrial gelatin products, generally have a bright color. Because the consumption of gelatin is transparent, white, very clean, and industrial gelatin impurities. If you use the industrial gelatin, manufacturers will add more flavor, coloring agent, coloring agent to cover up impurities, so the more bright colors may be made of industrial gelatin.
3. Industrial gelatin to do things, because it is to reduce costs, often when the quality, materials, technology, the environment is poor, so the product is not refined
