How to distinguish industrial gelatin from edible gelatin?
1. Industrial gelatin products generally have high impurities, low viscosity and toughness, poor quality and fragility. In this way, we can determine whether industrial gelatin has been added.
2. Edible gelatin is transparent, white and relatively clean, while industrial gelatin products are generally brightly colored. Because of too many impurities, some additives will be used to hide the impurities, so the bright color may imply the addition of industrial gelatin.
3. Generally, industrial gelatin is used to reduce costs. In many ways, including quality, materials, technology and environment, it can be relatively inferior and make a less refined product.
Gelatin test items and standards
The gelatin test items include:
- Qb/t 1995-2005 Industrial gelatin
