Abstract

The results of this study demonstrated the success of synthesis of zinc oxide nanoparticles (ZnO NPs) green and eco-friendly , using Leaf extract of Citrullus colocynthis and glycerol as reducing and stabilizing agents. The different characterization techniques , including FTIR, UV–Vis, XRD, SEM, and EDX, confirmed the successful formation of the nanoparticles, as well as their high purity and crystallinity. In addition , the biological assays revealed that the synthesized nanoparticles exhibited antifungal activity against both Penicillium ,chrysogenum and Aspergillus niger, two of the most important fungi responsible for food spoilage. These results that biosynthesized zinc oxide nanoparticles can serve as an effective and environmentally safe alternative to conventional chemical fungicides, contributing to the reduction of fungal deterioration in food products and improving their preservation and storage conditions
