  • Edible films rich in phenolic compounds were developed from citrus wastes.

  • Films with potential antioxidant activity were obtained without external extracts.

  • Residues of the orange peel process kept a considerable level of antioxidants.

  • Pectin films from citrus peel might help to protect foods against oxidation.
