Abstract
Eleven metals Zn, P, Mn, Fe, Mg, Ca, Na, K, Cu, Sr and Pa, chosen as c hemical descriptors, have been analysed by inductively coupled plasma atomic emission spectrometry. The metal content was studied in 41 samp les of green coffee belonging to the varieties arabica and robusta. Pa ttern recognition techniques such as principal component analysis and cluster analysis were applied in order to characterize the green coffe e varieties. (C) 1998 Elsevier Science B.V.
