摘要

Agar and banana (Gros Michel) powder composite film with silver nanoparticles were prepared using a solution casting method. Then, the ratio of agar and banana powder also the concentrations of silver nitrate solution have affected the properties of biocomposite film. These physical properties were characterized by UV-Vis spectrophotometer and colorimeter. The results indicated that biocomposite film with the mass ratio of agar to banana = 3:1 (A3B1_Ag50) was brown and had the maximum absorption of UV-Vis light at 432 nm. This biocomposite film exhibited strong antibacterial activity against both Escherichia coli and Staphylococcus aureus. Because of their microbial activity and physical properties, these biocomposite films have the potential to be used extending the shelf life of food packaging.
