Protein-Based Films and Coatings: An Innovative Approach

Abstract

Protein-based films and coatings are highly biodegradable and represent sustainable alternatives to petroleum-based materials. These materials possess commendable barrier properties, effectively safeguarding against oxygen, moisture, and aroma compounds, rendering them well-suited for various food packaging applications. Beyond their role in food packaging, coatings and films have significant applications in the biomedical and pharmaceutical domains. Their inherent biocompatibility and controlled release properties make them valuable for applications such as drug-delivery systems, wound dressings, and tissue-engineering scaffolds. Moreover, the adaptability of these films to exhibit stimuli-responsive behavior opens avenues for on-demand drug release and sensing capabilities. Despite these promising attributes, challenges persist in terms of the mechanical strength, water resistance, and scalability of the processing of protein-based films and coatings. Ongoing research endeavors are dedicated to refining protein extraction methods, incorporating reinforcing agents, and implementing strategies to optimize the overall performance of these materials. Such efforts aim to overcome existing limitations and unlock the full potential of protein-based films and coatings in diverse applications, contributing to the advancement of sustainable and versatile biomaterials.
