化学计量学在茶叶产地溯源中的应用研究进展OA

As an interdisciplinary subject integrating chemistry,mathematics and statistics,chemometrics can realize rapid identification and precise traceability of tea origin by multivariate analysis and modeling of detection data of characteristic components in tea,and has become the core technical support in the field of tea geographical origin traceability.This paper reviewed the research progress of chemometrics in tea origin traceability,with an emphasis on the ideas and applications of traditional chemometric methods and modern machine learning methods in con-structing origin discrimination models.The existing problems in current applications were analyzed,including in-sufficient model generalization ability,limited traceability accuracy in small areas,lack of unified standards and comprehensive databases.Finally,the future development directions to improve the traceability accuracy and practi-cality were prospected.This study provided scientific and reliable technical references for tea origin traceability and the protection of geographical indication products.
