Abstract

Magnetic nanoparticles (MNPs) have emerged as essential agents in food preservation, tackling significant issues related to shelf life extension, quality maintenance, and safety assurance. This thorough analysis consolidates current developments in MNP-based nano-packaging and nano-freezing technologies, emphasizing their processes, effectiveness, and commercial feasibility. Metallic nanoparticles augment packaging efficacy via antibacterial properties, oxygen absorption, and real-time freshness assessment, while transforming freezing techniques by inhibiting ice crystal development and maintaining cellular integrity. Notwithstanding their potential applications, regulatory uncertainties, toxicity issues, and scalability challenges necessitate collaborative multidisciplinary approaches. We rigorously survey the technological, environmental, and safety aspects of MNP deployment in the food sector and suggest research priorities for sustainable implementation.

摘要

磁性纳米颗粒（MNPs）已成为食品保鲜中的重要媒介，可解决与延长保质期、保持品质和确保安全相关的重大问题。本全面分析整合了基于MNPs的纳米包装和纳米冷冻技术的当前进展，重点介绍了它们的工艺、有效性和商业可行性。金属纳米颗粒通过抗菌性能、氧气吸收和实时新鲜度评估提高包装功效，同时通过抑制冰晶形成和维持细胞完整性来变革冷冻技术。尽管它们有潜在应用，但监管不确定性、毒性问题和可扩展性挑战需要跨学科的合作方法。我们严格审视了MNPs在食品领域应用的技术、环境和安全方面，并提出了可持续实施的研究重点。
