Abstract

Nanostructured biopolymer packaging represents an innovative approach to food packaging, offering enhanced responsiveness for real-time monitoring of food quality. By incorporating nanoscale materials such as nanoparticles, nanoclays, and nanofibers into biopolymer matrices, these smart packaging systems can detect changes in environmental factors such as humidity, temperature, and gas composition. The incorporation of nanostructures enhances the sensitivity, durability, and functionality of the packaging, allowing it to provide timely information about the freshness, spoilage, or contamination of the food product. This paper explores the potential of nanostructured biopolymers in creating adaptive packaging systems for the food industry, emphasizing their ability to respond to external stimuli and provide valuable insights into the status of the packaged food. Challenges related to scalability, cost, and the environmental impact of these nanomaterials are also discussed, alongside future directions for improving the performance and sustainability of nanostructured biopolymer packaging.
