Conteúdo:	This study assessed the potential application of Fourier-Transformed Infrared spectroscopy using AttenuatedTotal Reflectance (FTIR-ATR) coupled with multivariate approaches to characterize and detect adulterations inbutter cheeses (BC) with soybean oil (SO). In general, as the adulterations were performed, there is a decrease inband intensities related to proteins, while for most bands related to lipid, the substitution of butter oil (BO) bySO led to increases in their intensities up to 70% of fraud. The band near 3007 cm−1was evinced only inadulterated cheeses. Principal component analysis differentiated the samples validating the spectral observa-tions. A partial least squares model allowed the prediction of the percentage of SO added into the samples withlow residuals. FTIR-ATR spectroscopy associated with chemometrics showed good performance in the detection of butter cheeses?adulterations.
