随着茶叶产量的不断提升，茶叶产品质量安全问题日益受到关注，目前普遍使用的传统的化学检测和感官审评方法，无法实现在茶叶生产及流通过程中对茶叶品质进行实时监控。近红外光谱分析作为一种新兴技术，具有样品无损耗、结果客观以及快速简便等优点，能满足茶叶产品实时检测的需求。本文在概述近红外光谱分析技术的基础上，对国内外近红外光谱分析技术在茶叶品质分析、等级确定、种类识别和产地溯源和真伪鉴别等方面的研究进展进行了综述。分析了近红外光谱分析技术在推广应用中存在的问题，指出近红外作为一种二级分析方法，其模型适用范围具有局限性，同时对其灵敏度以及成本作出客观评价；对今后的发展及研究方向进行了展望，以期近红外光谱分析技术能够更好地应用于茶叶领域。

With the promotion of tea production, the quality and safety problems of tea have caught more and more attention. The traditional chemical method test and sensory evaluation cannot achieve in the process of tea production and circulation to monitor tea quality in real time. As a new technology, the near-infrared spectroscopy (NIRS) analysis can fulfill the demand of real-time detection, due to its characteristics such as non-destruction, objective result, rapid response, and high efficiency,etc. In the present paper, basic knowledge of NIRS and its analysis process were briefly introduced. The recent advance on the application of NIRS in tea quality analysis, grading, species identification and geographical origin traceability was reviewed. It indicated that the near infrared, as a secondary analysis method, there were restrictions and limitations with the model scope of application, and an objective evaluation of the sensitivity and the cost had been made. Finally, the existing problems of NIRS were pointed out and the prospect of NIRS technique was discussed, which was purposed to apply NIRS in the field of tea more effectually.
