摘要: 通过顶空固相微萃取结合气相色谱-质谱联用技术对燕麦与藜麦黄酒进行挥发性成分分析,共鉴定出挥发性成分86种,其中藜麦黄酒57种,燕麦黄酒55种,有26种是两种黄酒共有的。藜麦黄酒的挥发性物质组成为芳香族(64.09%,15种)、醇类(29.36%,7种)、酯类(4.37%,13种)、其他类(2.18%,22种)。燕麦黄酒的挥发性成分组成为(芳香族43.77%,14种)、醇类(27.39%,6种)、酯类(22.66%,15种)、其他类(6.18%,22种)。两种黄酒的含量较高的组分均为苯乙醇与异戊醇,同时在挥发性成分中均检测到具有抗氧化能力的物质,可以推测两种黄酒可能有抗氧化活性。Abstract: The volatile characteristics of Chinese oat wine and Chinese quinoa wine were investigated using headspace solid phase micro-extraction and gas chromatography-mass spectrometry. A total of 86 volatile components were identified with 26 kinds existing simultaneously in both. And there were 57 and 55 volatile components in Chinese oat wine and Chinese quinoa wine respectively. The volatile composition of Chinese quinoa wine was 15 kinds of volatile compounds(64.09%),7 kinds of alcohols(29.36%),13 kinds of esters(4.37%) and 22 kinds of other compounds(2.18%) while the Chinese oat wine was composed of 14 kinds of volatile compounds(43.77%),6 kinds of alcohols(27.39%),15 kinds of esters(22.66%) and 22 kinds of others(6.18%). The volatile compounds in high content were phenylethyl alcohol and 3-methyl-1-butanol. Some compounds such as BHA and BHT were also detected in both two wines and which suggested that Chinese oat wine and Chinese quinoa wine might have strong anti-oxidant activity.
