Introducción
Bioplásticos a base de proteínas son una clase de materiales biobasados, a menudo biodegradables fabricados a partir de proteínas como soja, gluten de trigo, caseína, suero, gelatina, colágeno, queratina, ceína y albúmina, así como proteínas estructurales microbianas y recombinantes más nuevas. Son de interés porque combinan materias primas renovables con propiedades formadoras de películas y funcionales que pueden ser útiles en envases, recubrimientos, películas agrícolas, productos biomédicos y otras aplicaciones de carga baja a moderada.
A diferencia de los plásticos fósiles comerciales, los bioplásticos a base de proteínas se definen menos por una única química de polímero que por una estrategia de formulación: las proteínas se plastifican, mezclan, reticulan, hidrofobizan o modifican de otro modo para crear materiales utilizables con rendimiento mecánico y de barrera específico. Su desarrollo refleja un cambio más amplio en la industria de los plásticos hacia materiales que pueden obtenerse de coproductos agrícolas y biode ...
