摘要：

A method that differentiates among different coffees is described. Characterization is by applying principal component analysis (PCA) to the chromatographic results, obtained either by static headspace capillary GC (S-HSGC) of the roasted ground coffee or by HPLC-UV analysis of Mocha coffee extracts, or to a combination of the results of both. The possibilities of this method are illustrated by some examples concerning the differentiation of coffee samples of different origins or submitted to different roasting treatments or in mixtures of different composition.
