Abstract:

To explore the flavor substances of different highland barley varieties, the volatile components of 8 highland barley varieties were analyzed and identified by gas chromatography-mass spectrometry (GC-MS). The results showed that a total of 40 compounds were detected in the flavor substances of the 8 highland barley varieties, including 10 aldehydes, 8 alcohols, 2 esters, 5 ketones, 3 acids, 4 aromatics, 4 hydrocarbons, 1 furans, 1 phenol and 2 other types. Aldehydes had the highest relative content in different highland barley varieties of 12.98%-58.09%, followed by acids of 3.99%-33.90%, alcohols of 6.88%-16.36% and ketones of 4.47%-12.78%. The classification analysis showed that the 8 highland barley varieties could be divided into two categories. ‘Goumang purple highland barley', ‘Longzi black highland barley', ‘1127', ‘Shanqing 9' and ‘Zangqing 320' had higher similarity and were classified as the same category, while ‘Zangqing 2000', ‘Zangqing 25' and ‘Xila 22' had higher similarity and were classified as the same category. When the Euclidian distance was 25, the two categories could be classified as the same one.

Key words: highland barley varieties, flavor substances, gas chromatography-mass spectrometry (GC-MS), principal component analysis (PCA), cluster analysis
