Abstract

Abstract: It is necessary to develop identification technologies for tea varieties and geographic origins due to increased adulteration in tea products. In this paper, we review the applications of high performance liquid chromatography fingerprint, near infrared spectroscopy, multi-spectral image texture technology, fluorescence spectroscopy and trace element analysis for the identification of tea varieties and origins. Meanwhile, their future development trends are also proposed.

Key words: tea, variety, origin, identification technology
