Abstract

Stimuli-responsive biopolymers represent a transformative class of materials that can adapt to environmental changes, offering enhanced functionality for food packaging applications. These biopolymers undergo reversible physical or chemical changes in response to external stimuli such as temperature, pH, moisture, or light, allowing for dynamic adjustments to protect food products and extend shelf life. By incorporating such adaptive properties, stimuli-responsive biopolymers offer improved food preservation, better interaction with food products, and a significant reduction in environmental impact. This paper explores the development and applications of stimuliresponsive biopolymers in sustainable food packaging, emphasizing their role in maintaining food quality, reducing food waste, and replacing conventional plastic packaging with more eco-friendly alternatives. Key advancements in the integration of stimuli-responsive biopolymers into smart packaging systems are discussed, alongside the challenges and future potential for widespread adoption.
