Gelatin is extracted from collagen and is a high molecular weight protein composed of 18
amino acids. Bovine hide , bones and fish scales are normally used for the production of the gelatin.
Gelatin can absorb 5-10 times of water and if heated,
it enters a sol state. Upon cooling, it enters a gel state.
Because of its special properties, gelatin is used in making pharmaceutical capsules, jelly,
industrial adhesives. Also gelatin is widely used in other applications.
