Abstract. The biosynthesis of Titanium nanoparticles (TiNPs) using Phyllanthus niruri extract presents an eco-friendly and sustainable approach to nanomaterial production. In this study, TiNPs were successfully synthesized and incorporated into a starch-polyvinyl alcohol (PVA) matrix to develop smart and active food packaging films. The P. niruri extract acted as a reducing and stabilizing agent, enabling the formation of biocompatible TiNPs with enhanced antimicrobial and antioxidant properties. TiNPs was characterised by UV-Vis spectrophotometer, zeta potential, FTIR, XRD and SEM. TiO2 had good resistance against food borne pathogens such as Escherichia coli, Staphylococus aureus, Shigella, Pseuomonas aeruginosa etc. The nanomaterial incorporated film can extend the shelf life of food materials. The integration of TiNPs into starch-PVA films improved their mechanical strength, thermal stability, and barrier properties while endowing the films with active functionalities, such as microbial inhibition and real-time freshness indicators. These hybrid films provide an innovative solution for extending shelf life, ensuring food safety, and reducing environmental impact. This study highlights the potential of plant-based nanotechnology in advancing sustainable food packaging systems.
