[Study on identification and traceability of tea material cultivar by combined analysis of multi-partial least squares models based on near infrared spectroscopy].

Abstract

The present study attempted to achieve the identification and traceability of tea material cultivar through combination of multi-partial least squares models and Euclidean distance, etc. The results indicate that with the samples manufactured with tea fresh leaves of cultivar Longjing 43, Qunti, Yingshuang and Wuniuzao as the analysis objects, 4 models were… (More)
