Conteúdo: | In order to reduce uncertainty in the results, we developed a method based on digital image processing to quantify coffee substitutes in roasted powders. The samples are filtered with cloroform, dried and homogeneized. The next step is a visual analysis of the samples by na electronic lupe. For those samples contaminated with coffee substitutes, we generated multispectral images through the use of a CCD camera connected to the lupe. The camera also transfered the images to a personal computer. The percents by weigh occupied by different coffee substitutes were obtained by the supervised classification using the software SpringCafe. The advantage of this non-destructive technique is the capability to analyze a high amount of samples and the lack of subjectivity.
