Summary: Intelligent colorimetric indicator films were prepared to monitor the freshness/spoilage of milk and fish by incorporating purple tomato anthocyanin (PTA) into chitosan (CS) matrix. The color change of the films was correlated with PTA content and pH values, showing potential application in monitoring food freshness/spoilage.

Summary: The massive use of petroleum-based plastics in food packaging has led to serious environmental issues, prompting the need to develop biodegradable polymer packaging. Chitosan, a natural polysaccharide with non-toxic, antimicrobial, and antifungal properties, is considered a promising material for food packaging. Recent studies have evaluated the potential of active and/or intelligent chitosan-based films in improving food preservation and monitoring. The addition of active compounds has been shown to enhance the mechanical, barrier and functional properties of chitosan films, with potential applications in antimicrobial and antioxidant activities.

Summary: Modified resazurin incorporating gelatin films were prepared to monitor the quality of packed shrimp in real time. The films showed uniform dispersion of the dye with minimal irregularities, and the addition of the dye improved the films' load-bearing ability and tensile strength without affecting transparency and water vapor permeability. The release rate of the dye depended on the food simulant, and the films exhibited noticeable color changes in shrimp packaging tests that corresponded well with TVB-N levels and pH changes.

Summary: The development of intelligent indicator film is a new trend in food packaging. It has been found that the addition of anthocyanin improves the hydrophobicity and oxidation resistance of the film, causing its color to change with pH. This intelligent indicator film can be used to detect the pH changes in salmon and determine its freshness.
