What is it about?
The results of the study demonstrate the viability of hydrolytic processes to obtain soluble keratin useful for biodegradable film formation for food application, that are harmless and more effective than solubilization by reduction of the disulphide bonds.

Why is it important?
Mil lions tonnes of keratinous wastes are generated annually globally. Due to a large variety of microflora present on the feathers, including pathogens, they should be treated quickly. We have demonstrated that the replacement of reduction reactions in keratin extraction by alkaline hydrolysis makes it more industrially viable and eliminates corrosive substances used which are a threat to the environment.
Perspectives
We plan to use soluble keratin obtained for the biodegradable film formation for food application.
