Abstract

The invention discloses a method for rapidly determining PienTzeHuang quality by using near-infrared spectroscopy. The method comprises the steps that: (1) representative PienTzeHuang samples are collected as a training set; (2) quality indicators of the PienTzeHuang samples in the training set are determined through a high-performance liquid chromatography method; (3) near-infrared spectral data of the PienTzeHuang samples in the training set is determined; the near-infrared spectral data is pretreated; and spectral data obtained after pretreatment is adopted as variables; (4) the spectral data obtained after pretreatment is associated with the quality indicators, such that a correction model is established; and the correction model is verified; and (5) qualities of PienTzeHuang to be tested are determined by using the verified correction model. With the method, whether a sample to be tested is suspicious can be rapidly determined. The method is suitable for rapid screening of counterfeit and inferior fake goods. Also, the method can be used for evaluating quality differences and stability of each batch of PienTzeHuang. The method has the advantages of short detection time, high speed, accurate determination, and capability of online detection. With the method, manpower and material resources can be greatly saved, and substantial economic and social benefits are provided.

Description
