Abstract: The aim of this study was to analyze the differences in the volatile flavor components of Kazakh dry-cured beef from two different feeding systems and three different muscle cuts. The volatile components were analyzed by an electron nose and solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS). The results of electronic nose analysis showed that there were significant differences in flavor components between the two feeding systems, but no difference was found between different muscle cuts. A total of 26 volatile compounds were detected by SPME-GC-MS, including 8 aldehydes, 7 alcohols, 6 aromatic benzene compounds, 3 aliphatic hydrocarbons, 1 ketone and 1 furan. The results of analysis of variance showed that the muscle cuts had a significant effect on the total amount of fat oxidation products (P < 0.05), while the feeding systems had a significant effect on the total amount of feed ingredients (P < 0.01).
