The volatile flavor compounds of roasted lamb in Shihezi, Xinjiang were determined by solid phase microextraction(SPME) coupled with gas chromatography-mass spectrometry analysis(GC-MS). Various SPME fibers were screened for their ability to extract the key volatile compounds. The optimal SPME fiber was selected as 75 μmCAR/PDMS based on sensitivity and key common compounds with projections greater than 0.80 in the loading matrix of principle component analysis(PCA). The correlation of different fibers(75 μ...
