Pharmaceutical gelatin is a high-grade gelatin product made from animal skins, bones and tendons. It is fat-free, rich in protein, and easily absorbed by the human body after complex physicochemical treatment. It is physically characterized by high viscosity, high freezing power, and easy to freeze. The quality and variety of gelatin directly affects the method and quality of the tablets that are made with the involvement of gelatin. Standard gelatin has higher adhesive and binding properties, resulting in harder and more adhesive coated or compressed tablets, as well as longer disintegration time.
