目的 探究新鲜度指示标签在冷鲜肉包装领域的研究现状及应用进展，为新鲜度指示包装的应用提供理论基础。方法 介绍新鲜度指示标签的定义和功能，并根据生鲜肉类腐败过程中产生的不同特征反应物进行分类，阐述不同类型指示标签的工作原理。探究新鲜度指示智能标签在国内外的研究现状及应用，并分析制约智能指示标签发展的因素。结论 新鲜度指示标签在一定程度上代表着智能标签的发展程度，是食品包装未来发展的研究热点和方向之一；由于成本高、制作工艺复杂等因素的影响，国内还没有达到商业化程度，还需从技术角度继续深入研究，以开发出低成本、高精度的新鲜度指示标签，进而推动智能标签的商业化应用。

The paper aims to explore the research status and application progress of freshness indicator labels in chilled meat packaging, and to provide a theoretical basis for application of freshness indicator packaging. The definition and function of the freshness indicator label are introduced. The fresh meat is classified based on the different characteristic reactants generated during corruption. The working principle of different types of indicator labels is explained. The research status and application of the freshness indicator smart label at home and abroad are explored; and the factors restricting the development of the intelligent indicator label are analyzed. The freshness indicator label represents the development degree of smart label to a certain extent. It is one of the research hotspots and areas for future development of food packaging. However, due to high cost and complex manufacturing process, its domestic level has not yet reached commercial height. It is necessary to further research and develop low-cost, high-precision fresh indicator labels from a technical perspective to promote the commercialization of smart labels.
