Feathers, hair, wool and other materials which are composed substantially of keratin may be solubilized in alkaline solutions containing low concentrations of hydrogen peroxide. Solubilization is virtually complete at ambient temperatures and normal atmospheric pressures, yielding peptide products in excess of 75 % by weight of the keratin source. The peptides or amino acid mixtures obtained by hydrolysis of the peptides are rich in cysteine derivatives and are suitable for use as animal feed supplements. The solubilization process itself may be used therapeutically in human and veterinary medicine. |
