Anthocyanin-sensitized gelatin-ZnO nanocomposite based film for meat quality assessment.

Meat is considered a highly perishable food, and the interest in developing tools to monitor meat quality products has increased these years. A novel gelatin-ZnO-anthocyanin ternary nanocomposite film is proposed as a sensitive layer to meat quality monitoring in the present work. The incorporation of anthocyanin (ATH) on gelatin-ZnO (G-ZnO) film induced a sensitivity improvement of films towards ammonia vapor according to impedance measurements.
