Abstract

The purpose of this study was to analyze the volatile flavor components in yak meat from different producing areas in Qinghai province, and to find out the compounds of key volatile flavor components in yak meat using principal component analysis method. The volatile flavor components in the longissimus dorsi, biceps flexor cruris and intercostal muscles of yak from three male and three female yaks were selected from 5 different producing areas in Qinghai province were analysis identified by head-space solid-phase microextraction and gas chromatography-mass spectrometry (HS-SPME-GC-MS) technique. The results showed that 34 volatile flavor components were identified from three parts of muscle of yaks, including aldehydes, ketones, alcohols, acids, alkanes, nitrogen-containing heterocyclic compounds and sulfur-containing compounds. Eight compounds like hexadecanal, octadecanal, nonanal, benzaldehyde, octanol, 2,3-pentanedione, 3-hydroxyl-2-butanone and caproic acid were found to be key volatile flavor components in yak meat by principal component analysis (PCA). The results of PCA for producing area show that 30 samples can be divided into three categories according to the producing area and grassland type.
