Abstract
With the increasing global attention on food safety and sustainable development, traditional food preservation technologies are struggling to meet modern demands. This study aims to explore food preservation techniques based on novel packaging materials to extend shelf life and reduce resource waste. By synthesizing and characterizing multifunctional composite materials with antibacterial, antioxidant, and gas barrier properties, and applying them in simulated food systems, the preservation effects under various environmental conditions were systematically evaluated. The material formulation was optimized using response surface methodology, and its practical application potential was validated through sensory evaluation, microbial analysis, and physicochemical indicator assessment. Results indicate that the developed novel packaging materials can significantly inhibit microbial growth, delay food oxidation processes, while maintaining excellent mechanical properties and eco-friendly characteristics. The innovation of this study lies in the integration of nanotechnology with natural active components, achieving an efficient, safe, and biodegradable solution for food preservation, providing significant reference for the advancement of green packaging technology.
