Comparison of the properties of multi-composite fish gelatin films with that of mammalian gelatin films

► Grouper gelatin films had higher Mechanical and barrier properties than redsnapper films. ► Incorporation of MMT and chitosan improved the Tensile strength and Young's modulus of the films. ► Water solubilities were lower in the films incorporated with chitosan. ► The water vapour transmission rates of fish gelatin films were reduced by the addition of MMT. ► SEM micrographs showed smoother surface in gelatin-MMT films.
