Abstract
ABSTRACT Food preservation is an important issue in the food industry. Traditional packaging materials face limitations in extending food shelf life and reducing food waste. In recent years, antibacterial packaging doped with protein‐based polymers and natural antibacterial agents has become a subject of research due to their environmental friendliness and biodegradability. In this paper, various methods of doping protein polymers with natural antimicrobial agents and their effects on food packaging properties are reviewed. Through technologies such as solution casting, extrusion blow molding, electrospinning, calendering, and 3D/4D printing, natural antibacterial agents can be effectively and uniformly dispersed in protein‐based polymers, thereby improving their antibacterial properties a
