Abstract:
This study reviewed the progress of three chromatographic techniques (liquid chromatography, gas chromatography, comprehensive two-dimensional chromatography) and their applications in coffee quality control. The importance and application prospect of chromatographic fingerprint technology were further revealed by describing the origin, distribution, main components and flavor characteristics of coffee, as well as the construction method of chromatographic fingerprinting. As a physicochemical separation and analysis method, chromatography overcame the shortcomings of traditional spectroscopy and mass spectrometrythat required complex sample processing and separation before analysis. As one of the most important analytical methods and one of the most widely used methods, chromatographic separation technology had the characteristics of high separation efficiency, fast analysis speed and high detection sensitivity, making it an indispensable position in the coffee quality control. . In practical applications, chromatography was often combined with chemometrics to achieve the quality control of coffee productsl.
