Development of pectin films with pomegranate juice and citric acid

•The effects of pomegranate juice and citric acid on pectin films were studied.•Pomegranate juice acted as plasticizer, improving elongation.•Citric acid improved tensile strength, modulus, and water vapor permeability.•Citric acid reduced film solubility, possibly due to a crosslinking effect.•The red color was decreased by citric acid, suggesting anthocyanin destabilization.
