Abstract
Nanotechnology, as a crucial branch of modern science and technology, has demonstrated extensive application prospects in the field of food preservation in recent years. This study aims to investigate the mechanisms of action of nanomaterials in food preservation and assess their safety, thereby providing scientific evidence and technical support for the food industry. By integrating literature analysis with experimental validation, this research systematically examined the inhibitory effects of various nanomaterials, such as silver nanoparticles and zinc oxide nanoparticles, on microbial activity and their protective roles in maintaining food quality. The findings indicate that nanomaterials can significantly extend the shelf life of food while effectively reducing the risk of spoilage and pathogenic microbial proliferation. Furthermore, this study developed a comprehensive safety evaluation system based on multiple indicators to quantify the potential risks associated with the practical application of nanomaterials. An innovative contribution of this work is the proposal of a dynamic monitoring technique for assessing the migration behavior of nanomaterials, which was combined with toxicological data to conduct an in-depth analysis of their long-term safety. The results suggest that, under conditions of appropriately controlled dosage and usage parameters, nanotechnology can be safely and efficiently applied to food preservation, offering new strategies to enhance food safety and prolong shelf life. This achievement not only enriches the theoretical fr amework of food science but also provides a foundation for the formulation of relevant regulatory standards.
