Casein-based film enriched with lignin as a biodegradable substrate for enzyme immobilization.

ABSTRACT: In the last decades, the negative impact of petroleum derived materials on the environment is more and more evident; beyond the unavoidable reduction in the use of classical plastic, another promising approach is the development of alternative materials prepared starting from natural, biodegradable, and more sustainable biomolecules, particularly undervalued or discarded ones. Caseins are the most abundant proteins in milk, with important nutritional value but also interesting film-forming properties. Lignin is a polyphenolic polymer found in wood and derived from a by-product of the cellulose extraction processes; it is well known for its antibacterial, antioxidant, and UV-protecting properties. In the present work, casein was isolated from UHT skimmed bovine milk through acidification an
