Abstract: Tea is an economic crop with Chinese characteristics and a high value-added natural beverage. Rapid and accurate nutrition diagnosis and quality monitoring are inevitable requirements for ensuring the quality of tea products. The limitations of traditional tea quality assessment methods and recent emerging rapid detection techniques were revealed in this study. The characteristics of near-infrared spectroscopy (NIRS) technology and the evolution of keywords from the published studies on the application of the NIRS method in the field of tea were presented. The research progress on the rapid detection of key components of tea products, the quality control of tea products, the development of the digital fast NIRS analyzer, and the development of technical standards were reviewed in detail. The development directions of the NIRS technology in the field of tea analysis were proposed and discussed.

Key words: near-infrared spectroscopy technology, tea, quality control, equipment development, standardization
