Description and Uses

Gelatin does not occur in nature as such, but is derived by hydrolysis of collagen, the chief protein component in connective tissues of the animal body. The major sources of collagen are cattle hides, pig skins and bones. The resulting gelatin is of two types commonly designated A and B, depending upon which of two processes are used to convert the collagen into gelatin. Type A gelatin is derived primarily from pig skin by acid processing; it has an isoelectric point between pH 7 and pH 9. Type B is from cattle hides and bones by alkaline or lime processing and has an isoelectric point between pH 4.7 and pH 5.1.

gelatin is used as a natural sealant against moisture loss and as a formulation thickener. The films produced by gelatin are tacky when moist and hard, and brittle when dry. It is obtained by the partial hydrolysis of mature collagen derived from the skin, connective tissue, and bones of animals. It does not have the waterbinding ability of soluble collagen.
