METHOD FOR IDENTIFYING PRODUCING AREA OF RIZHAO GREEN TEA

原文（中国語）

A method for identifying a producing area of Rizhao green tea is provided to identify Rizhao green tea in a trace amount accurately, conveniently, and rapidly, providing a new theoretical method and scientific basis for tracing the producing area of the Rizhao green tea. The method includes the following steps: S1, collection and preprocessing of tea leaf samples; S2, thermogravimetric analysis-Fourier transform infrared spectroscopy (TGA-FTIR) coupled testing; S3, infrared spectrogram analysis; S4, thermogravimetric-differential thermogravimetric spectrogram analysis; S5, estimation of kinetic parameters of the Rizhao green tea; S6, calculation of the pyrolysis parameters of the Rizhao green tea; and S7, establishment of an Ea prediction model for Rizhao green tea. A prediction model is established for the activation energy Ea of a Rizhao green tea leaf sample Y1, and an input to the prediction model is merely three characteristic parameters. The problem of model complexity is fundamentally solved.
