  • Optical, microstructural, functional and nanomechanical properties of Aloe vera gel, gellan gum and blend edible films.

  • Improvement of optical properties in blend (Aloe vera/ gellan gum) film.

  • Microscopy and image analysis allows characterizing and elucidating a crosslinked structure among the polysaccharides of the blend.

  • Water sorption capacity, water vapor permeability and nanomechanical properties were enhanced in the blend film.

  • Property-structure-functionality relationships of Aloe vera gel, gellan gum and blend edible films.
