Abstract

The goal of this study was to examine the possibility of verifying the origin and authenticity of Polish cheese, Oscypek marked with protected designation of origin (PDO) label, based on its volatile profile. Oscypek and its false imitations Oscypek-like cheeses were analyzed using a solidphase microextraction-mass spectrometry method (SPMEMS), which involved volatiles extraction by SPME with subsequent volatiles characterization by MS without particular components separation by gas chromatography. Collected data were treated using principal component analysis (PCA), linear discriminant analysis (LDA), soft independent modeling of class analogy (SIMCA), and support vector machines (SVM). The results of this study demonstrated that SPME-MS method combined with chemometric tools can be successfully used as electronic nose and applied to detect mislabeling and adulteration of PDO Oscypek cheese
