Biodegradable film based on lemon peel powder containing xanthan gum and TiO2–Ag nanoparticles: Investigation of physicochemical and antibacterial properties

The aim of this study was to prepare a biodegradable film of sour lemon peel waste. The film of lemon peel powder (LPP) was modified with xanthan gum (XG) and TiO2–Ag nanoparticles (LPP/XG/TiO2–Ag). For this purpose, a central composite design was used to investigate the effect of xanthan gum and Ti...
