The traditional sensory evaluation and wet chemical detection of tea quality have limitations including strong subjectivity,timeconsuming and laborious determination. As a new type of analytical technique,near infrared spectroscopy has the advantages of fast,nondestructive,and objective results,and has been widely used in tea. Based on introducing the principle of nearinfrared spectroscopy technology,this article mainly reviewed the use of near infrared spectroscopy in analyzing the quality of tea fresh leaves,detecting component,identifying tea grade and tea species,tracing tea geography and analyzing tea products deeply processed. The problems in using nearinfrared spectroscopy technology in tea are analyzed. Some targeted countermeasures were proposed. It is expected that near infrared spectroscopy technology can provide solid scientific and technological support for the development of tea industry.
