Effects of hydrogen peroxide and Fenton's reagent on the properties of film from cuttlefish (Sepia pharaonis) skin gelatin

► H2O2 and Fenton's reagent induced cross-linking of gelatin. ► H2O2 and Fenton's reagent improved the mechanical properties of the gelatin film. ► H2O2 (0.02 M) or Fenton's reagent (0.02 M H2O2 + 0.002 M FeSO4) was optimal.
