The development of excellent biocomposite edible films are produce from nontoxic, biocompatible, biodegradable and low coast biopolymers as have a versatile biological activities and provided plenty of opportunities for further development of functional biomaterials in various field. The biopolymers chitosan and alginate used in this study. They are abundantly available natural polysaccharides it can be used in various applications. In this present study, the curcumin (Cu) loaded chitosan (Ch) and alginate (Al) impregnated with silver nanoparticles (AgNPs) films are prepared by solvent casting method. The prepared composite films were characterized by UV visible spectroscopy (UV), Fourier transform infrared spectroscopy (FTIR), and Transmission electron microscopy (TEM). The morphological, mechanical and optical properties of the composite films are identified by using conventional methods. The obtained results, showed that the increase of chitosan content in the composite result in the decrease of water absorption capacity. The results have shown, the Cu-Ch-Al-AgNPs composite films shows high level of antibacterial property when compared to the control Al-AgNP films. This study suggests that Cu-Ch-Al-AgNP film may be potential candidate as a packaging material for food packaging application.
