Fourier Transform Infrared Spectroscopic Analysis of Liupu Tea with Different Aging Times
摘要
Abstract
Liupu tea power with different ageing times and aqueous extracts were analyzed by Fourier transform infrared spectroscopy (FTIR) and their spectral characteristics were also compared. Results showed that each tea sample had its own unique infrared spectrum due to various aging times. Meanwhile, an obvious difference between the infrared spectra of Liupu tea power and its extracts was observed. Liupu tea samples with different aging times could be distinguished from each other according to peak number, wave number, peak shape and relative intensity in their infrared spectra and secondary derivative spectra. Therefore, FTIR proved a rapid, simple, and direct method for the identification of Liupu tea with various aging times.关键词
