采用气相色谱质谱-联用分析法分别对2009年至2013年五个年份的川藏高原霞多丽冰酒进行了香气成分分析。结果表明，五个年份冰酒中所含的主要香气成分为酯类，醇类和酸类物质等。在2009年至2013年的冰酒中分别检测到26种、22种、53种、23种和38种香气成分。2009年冰酒中酯类10种（75.44%），醇类6种（11.16%），酸类3种（7.36%）和萜烯类3种（2.30%）；2010年酯类9种（74.47%），醇类5种（14.67%），酸类3种（6.75%）和萜烯类2种（1.94%）；2011年酯类16种（62.77%），醇类10种（16.49%），酸类4种（8.6%）和萜烯类3种（2.49%）；2012年酯类9种（78.8%），醇类3种（8.92%），酸类3种（9.16%）和萜烯类3种（1.62％）；2013年酯类14种（66.13%），醇类4种（10.83%），酸类4种（13.05%）和萜烯类4种（4.65%）。

GC-MS analysis of aroma compounds of Chardonnay icewine at different years in Sichuan-Tibet plateau

The aroma components of Chardonnay ice wine at the years of 2009 to 2013 were analyzed by the methods of solid-phase micro-extraction and gas chromatography mass spectrometry. The results showed that the substances of esters, alcohols, acids and terpene were the main aroma components of Chardonnay icewine at five years. The aroma components kinds in Chardonnay icewine at the years of 2009 to 2013 were 26, 22, 53, 23, and 38, respectively. In the icewine of 2009, there were 10 kinds of esters (75.44%), 6 kinds of alcohols (11.16%), 3 kinds of acids (7.36%) and 3 kinds of terpene(2.30%) were detected. In the icewine of 2010, 9 kinds of esters(74.47%), 5 kinds of alcohols(14.67%), 3 kinds of acids (6.75%) and 2 kinds of terpene (1.94%) were detected. In the icewine of 2011, 16 kinds of esters (62.77%), 10 kinds of alcohols (16.49%), 4 kinds of acids (8.6%) and 3 kinds of terpene(2.49%) were detected. Furthermore, in the icewine of 2012, 9 kinds of esters(78.8%), 3 kinds of alcohols (8.92%), 3 kinds of acids(9.16%) and 3 kinds of terpene(1.62%) were detected. In the icewine of 2013, 14 kinds of esters(66.13%), 4 kinds of alcohols (10.83%), 4 kinds of acids (13.05%) and 4 kinds of terpene (4.65%) were detected.
