Consumers' sensory perception of the adulteration was evaluated by a triangular test of the coffee beverages. Samples containing above 0.5% of coffee husks from pure coffees were discriminated by principal component analysis of the infrared spectra. A partial least-squares regression estimated the husk content in samples and presented a root-mean-square error for prediction of 2.0%. The triangular test indicated that were than 10% of coffee husks are required to cause alterations in consumer perception about adulterated beverages.por--BrasilQuímica Nova-CoffeeAdulterationChemometricsEspectroscopia no infravermelho médio e análise sensorial aplicada à detecção de adulteração de café torrado por adição de cascas de caféMid-infrared spectroscopy and sensory analysis applied to detection of adulteration in roasted coffee by addition of coffee husksinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleTavares, Katiany MansurPereira, Rosemary Gualberto Fonseca AlvarengaNunes, Cleiton AntônioPinheiro, Ana Carla MarquesRodarte, Mírian PereiraGuerreiro, Mário Césarinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFJFinstname:Universidade Federal de Juiz de Fora (UFJF)instacron:UFJFTHUMBNAILEspectroscopia no infravermelho médio e análise sensorial.pdf.jpgEspectroscopia no infravermelho médio e análise sensorial.pdf.jpgGenerated Thumbnailimage/jpeg1610https://repositorio.ufjf.br/jspui/bitstream/ufjf/8215/4/Espectroscopia%20no%20infravermelho%20m%c3%a9dio%20e%20an%c3%a1lise%20sensorial.pdf.jpg4c0da20d5c726628df7fe9e4d4af1789MD54ORIGINALEspectroscopia no infravermelho médio e análise sensorial.pdfEspectroscopia no infravermelho médio e análise sensorial.pdfapplication/pdf652921https://repositorio.ufjf.br/jspui/bitstream/ufjf/8215/1/Espectroscopia%20no%20infravermelho%20m%c3%a9dio%20e%20an%c3%a1lise%20sensorial.pdfdc917dc2929420ce6407ab4cc1daae99MD51LICENSElicense.txtlicense.txttext/plain;
