摘      要：Plastic-based food packaging cannot prevent food deterioration due to microbial infestation and has a short shelf life, resulting in food being unfit for consumption after a period of time. Nanotechnology s use in nearly every industry has gotten a lot of attention in the previous few decades. The green technique for nanoparticle production is a long-term solution that has fewer negative effects and is as efficient as chemical approaches. The goal of this research is to create titanium dioxide nanoparticles utilizing a green synthesis technique including aloe vera plant extract. Since the green method of nanoparticle synthesis has some advantages over chemical and physical methods, it would be a sustainable approach to use the plant-based nanocomposite films to combat the problem of food spoilage. To produce nanocomposite films, the manufactured nanoparticles were mixed with starch. Nanocomposite films were then subjected to antimicrobial susceptibility testing against Pseudomonas aeruginosa and Escherichia coli. As titanium holds antimicrobial potential through generation of reactive oxygen species when UV irradiated, it was evident from the results that green synthesized titanium dioxide-starch nanocomposites are equally efficient to be used as an alternative to food packaging materials. © 2022, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
