摘 要
食品包装设计在保障食品品质和延长货架期方面具有重要作用，但其具体作用机制尚需深入探讨。本研究以现代食品包装技术为背景，旨在揭示包装设计对食品品质保持的内在机制及其影响因素。通过结合实验分析与理论建模，选取典型食品类别进行对比研究，重点考察包装材料特性、结构设计及功能性涂层对食品物理、化学及微生物变化的影响。结果表明，优化的包装设计能够显著降低氧气渗透率、水分迁移以及光照对食品成分的破坏，从而有效延缓食品品质劣变。此外，创新性地引入智能包装监测系统，可实时反馈食品状态，进一步提升包装的主动保护能力。本研究不仅为食品包装设计提供了科学依据，还提出了基于多维度协同优化的设计策略，对推动食品包装技术进步和产业升级具有重要意义。

Abstract
Food packaging design plays a crucial role in ensuring food quality and extending shelf life, yet the underlying mechanisms require further exploration. This study, set against the backdrop of modern food packaging technologies, aims to uncover the intrinsic mechanisms by which packaging design preserves food quality and identifies influencing factors. By integrating experimental analysis with theoretical modeling, typical food categories were selected for comparative research, focusing on the effects of packaging material properties, structural design, and functional coatings on the physical, chemical, and microbial changes of food. The results indicate that optimized packaging design can significantly reduce oxygen permeability, moisture migration, and light-induced degradation of food components, effectively slowing down the deterioration of food quality. Furthermore, the innovative incorporation of smart packaging monitoring systems enables real-time feedback on food conditions, enhancing the proactive protective capabilities of packaging. This study not only provides a scientific basis for food packaging design but also proposes a multidimensional collaborative optimization strategy, which holds significant implications for advancing food packaging technology and promoting industrial upgrading.
