The gelatin is extracted from collagen, the main structural protein of connective tissues and bones. After the treatment of the raw material, the collagen is converted into gelatin through the extraction, in hot water, of tissues rich in collagen. The physical properties of the gelatin vary according to the molecular composition , depending on the type of the raw material used and the manufacturing process. The technical gelatin is commercially classified by its jelly strength and viscosity but there are other physical, chemical and bacteriological features that prove its quality.
