Synthesis and characterization of pH-responsive intelligent packaging film based on polyvinyl alcohol/ chitosan/ cellulose containing curcumin

A pH-responsive intelligent packaging system based on polyvinyl alcohol (PVA), chitosan, and cellulose with the addition of curcumin as bioactive agents was synthesized and characterized for packaging chicken. The results of the characterization tests showed that the addition of curcumin significantly altered the morphology, mechanical, and barrier properties of the composite films. According to the results, only the films containing curcumin exhibited antibacterial activity. These findings indicate that the prepared films can serve as reliable indicators for tracking the freshness and safety of packaged chicken.
