A method of preparing partially hydrolyzed soluble elastin from fibrous protein containing material comprised of insoluble elastin and collagen comprising:
- treating the fibrous protein containing material with an aqueous solution of a member selected from the group consisting of an alkali earth metal hydroxide and mixtures thereof in the presence of an agent which prevents overswelling of the fibrous protein, said treatment removing substantially all of the hair and fat from the fibrous protein;
- hydrolyzing the polypeptide chains of the collagen to form oligopeptides;
- separating the oligopeptides formed of the collagen from the insoluble elastin;
- treating the insoluble elastin with ammonium persulfate;
- partially hydrolyzing the treated elastin;
- and
- recovering substantially pure partially hydrolyzed soluble elastin.
