Resumo
This paper describes an approach
for the colour-based classification of RGB (red-green-blue) images, acquired using a common scanner, of commercial carbonated
soft drinks. Mean histograms of image colour channels were evaluated for the PCA classification of 29 brands of Guaraná, Cola, and
orange flavors. Loadings for principal component axes resulted in different patterns for sample grouping on score plots according to
RGB histograms. pH, sorbic acid and sucrose measurements were also correlated to the analyzed brands through PCA score plots
of the digitalized images.
