3个地区赤霞珠干红葡萄酒香气成分研究

Aroma Components in ‘Cabernet Sauvignon’ Wines from Three Areas Different Production Areas

以3个不同地区(四川西昌、陕西杨陵和陕西蓝田)2002年的赤霞珠干红葡萄酒为材料,利用GC/M S技术对其香气成分进行了研究。结果表明:从3种赤霞珠干红葡萄酒中共检出54种香气成分,其中酮类3种,醇类11种,酯类18种。杨陵酒样检出17种成分,蓝田酒样22种,西昌酒样31种。醇类是3种酒所有香气成分中相对含量最高的一类物质(蓝田酒95.48%,杨陵酒65.99%,西昌酒42.73%),其次是酯类(西昌酒37.00%,杨陵酒33.87%,蓝田酒4.22%)。蓝田酒和杨陵酒苯乙醇含量最高,分别达56.46%和46.31%,西昌酒1-戊醇含量最高(29.13%);丁二酸乙酯是杨陵酒(18.1%)和蓝田酒(2.96%)含量最高的酯类,而西昌酒苯二甲酸二异辛酯含量(18.94%)最高。此外,3种酒均检测出萜烯、呋喃、烷烃等类化合物,但含量较少(杨陵酒1.15%,蓝田酒0.28%,西昌酒9.09%)。3种酒香气成分既表现出品种的一致性,在种类组成和相对含量等方面亦表现出较大差异。

The aroma components from dry red wines of Cabernet Sauvignon produced in 2002 from three areas,Xichang of Sichuan Province,Yangling of Shaanxi Province,and Lantian of Shaanxi Province were analyzed by GC/MS.54 aroma components were detected from 3 wines totaaly,including 3 ketones,11 alcohols,and 18 esters,17 aroma components were detected from the wine from Yanling,22 from Lantian,and 31 from Xichang.Alcohols were the main components in three wines,accounting for 95.48% in the wine from Lantian,65.99% from Yangling,and 42.73% from Xichang.The next were esters,accountion for 37.00% in the wine from Xichang,33.87% from Yangling,and 4.22% from Lantian.Wines from Lantian and Yangling had the highest contents of phenylethanol,accounting for 56.46% and 46.31% respectively.Whereas,wine from Xichang had the highest content of 1-pentanol.Among the esters,wines from Yangling and Lantian had the highest contents of ethyl succinate,18.1% and 2.96% respectively.Whereas wine from Xichang had the highest content of diisooctyl phthalate(18.94%).In addition,other components with low contents were also found from the three wines,such as terpenes,furfurans,and alkanes.
