Sažetak

In order to identify the volatile compounds in Polish Carpathian goat meat, baked leg muscle samples from two groups aged 12 and 9 months were subjected to a headspace solid phase microextraction gas chromatography/mass spectrometry (HS–SPME–GC/MS). The multivariate statistics was done, which included the Fisher's ratio method for variables pre-selection, and principal component analysis together with linear discriminant analysis. 93 volatile compounds were found, out of which 49 were confirmed on two columns: non-polar ZB-5MSi and polar ZB-Wax, whereas 5 were verified by using of authentic standards. HS-SPME-GC/MS analysis together with chemometrics occurs to be the effective tool for the discrimination of the meat from the Carpathian goats aged 12 and 9 months. The first two principal components accounted for 88.8% of the total variance. These values for the first three principal components were 94.6% and the classification accuracy values for both groups were 100%.
