Pectin/Xylitol Incorporated with Various Metal Oxide Based Nanocomposite Films for its Antibacterial and Antioxidant Activity

摘要

In this work, we have developed homogeneous, biogenic biopolymers blended different metal oxide nanoparticles by simple solution casting method. The antibacterial activity of bio blended nanocomposite films with various metal oxide nanoparticles such as silver, zinc and copper were carried out against pathogenic bacteria such as E. coli and 5. aureus was evaluated using the agar well diffusion method, which revealed that silver based blended nanocomposite films showed enhanced bactericidal activity which is further carried out for antioxidant activity using DPPH and ABTS scavenging assay. As a result of this interaction, the pectin and xylitol blended silver nanocomposite film matrix evidenced an IC50 of 50.59 with a strong antioxidant activity, which makes it suitable for future food wrapper and wound healing applications.
