Abstract: Chaotic market situation was formed for identifying the quality of tea difficultly, which affected the modern development of tea industry.In recent years, more and more application to sensory evaluation, quality control and geographical origin determination of tea was studied by fingerprinting techniques, which provides effective technical support for the identification of the quality of tea. The methods of fingerprint technique were reviewed in this paper, including fingerprintings based on gas chromatography(GC), liquid chromatography(LC), capillary electrophoresis (CE), infrared (IR)and near-infrared (NIR)spectroscopy, nuclear magnetic resonance (NMR), etc. The problem of the fingerprint in tea applications were analyzed, and the development in tea was predicted in the paper, The article also gives a theoretical basis and reference for further studies of the fingerprint in tea.

Key words: tea, fingerprinting, gas chromatography, liquid chromatography, nuclear magnetic resonance, spectroscopy
