Abstract (English):
Possibilities of granulometric analysis of composition of the grain and spectral analysis of the flat contour of coffee grains to determine the presence of spoiled grains, the grain size or impurities and classification of shape of grain contours have been analyzed and compared. The results of granulometric analysis and spectral analysis of the shape of contours have been presented for ten samples of coffee. The possibility of an objective grains quality control has been demonstrated. The fast convergence of a result as an advantage of spectral analysis has been shown.
