- ... This work presents the development of methods for classification of clonal varieties of coffee using chemometrics coupled to Raman spectroscopy and direct sample analysis. Spectra were collected directly from each bean in triplicate, and the homogeneity of the sample’s surface was studied. The spectral range between 1200 and 1800 cm−1 is related to organic groups that are relevant for the discrimi ...
