Abstract
Gelatin is extracted from collagen-containing substances by liquefaction with hydrogen peroxide as the sole lyotropic agent. Collagen-bearing tissue is liquefied through agitation with hydrogen peroxide at about 45.degree.-60.degree. C. for from about 4 to about 24 hours at concentrations such that the weight of peroxide is from about 1/3 to 3 times the weight of collagen protein within the system. The thus formed colloidal solution gels upon cooling, and gelatin degradation is minimized by removing peroxide from the solution before the gelatin is dried.
