Chitosan/gelatin based intelligent pH-sensing indicator film was fabricated by incorporating zinc oxide nanoparticles and black peanut seed coat anthocyanins, and was used to monitor the freshness of shrimp at 4 °C. A distinctive color change of the film was consistent with the rising trend of TVB-N...
