茶叶产地溯源与鉴别检测技术研究进展

Progress in Analytical Methods for the Detection of Geographical Origin and Authenticity of Tea(Camellia sinensis)

茶叶是我国重要的特色农产品,地域特色和品质特征明显,溯源与鉴别检测技术对保证其产地和品质真实性具有重要意义。本文系统介绍了国内外茶叶产地溯源和种类鉴别中稳定同位素、多矿物元素、近红外光谱和化学指纹图谱等检测技术的研究进展,分析茶叶产地溯源与鉴别检测技术面临的关键问题,提出茶叶产地溯源和鉴别的研究重点,对我国茶叶原产地保护具有积极的借鉴作用。

Tea （Camellia sinensis） is one of the important agricultural products with obvious regional characteristics. Analytical methods are very important for the protection of geographical origin and authenticity of tea. The developments of analytical methods including stable isotope determination, muhi-elements determination, near infrared reflectance spectroscopy, chemical fingerprint and others were reviewed. Major problems on tea origin and authenticity detection were discussed in this study, and some suggestions were also proposed which would be useful for the protection of geographical origin of tea in China.
