Abstract:
Antimicrobial packaging is increasingly being used to inhibit the growth of pathogenic microorganisms in food products without the use of preservatives. Zinc oxide (ZnO) nanoparticles, which possess antibacterial properties and are safe for humans, can be used as an active component. This makes it possible to incorporate such nanoparticles into food packaging. This study aims to produce ZnO nanoparticles with plant extract using a «green» synthesis method and to study their antibacterial and fungicidal activity. The authors obtained zinc oxide nanoparticles by biosynthesis using an extract of common tansy Tanacetum vulgare L. The synthesis parameters that achieved the highest quantitative yield of the target substance were determined: ZnSO4 salt concentration of 25%, incubation temperature of 50 °C, reaction medium pH of 5.8–5.9. Nanoparticles were isolated from the reaction mixture by calcination at 400 °C for 120 min. The physicochemical characteristics of the obtained nanoparticles were studied using UV and IR spectroscopy, scanning electron spectroscopy, energy-dispersive spectroscopy, and dynamic light scattering. The average particle size was (340.2 ± 9.2) nm. A thermogravimetric study confirmed the successful removal of organic impurities. Antimicrobial testing demonstrated high activity of the nanoparticles against the gram-positive bacteria Bacillus subtilis and Staphylococcus citreus, as well as strong fungicidal activity against the yeast Candida tropicalis. Prolonged antimicrobial activity was observed only for ZnO nanoparticles, increasing their potential as a component of biodegradable food packaging for extending the shelf life of products. The developed method for the biosynthesis of zinc oxide nanoparticles using tansy ensures the environmentally friendly production of an active material for antimicrobial packaging, which is relevant for the food industry and environmental protection.
