摘要: 采用同时蒸馏萃取(SDE)技术,联合GC-MS鉴定方法分析了9个安化千两茶中的挥发性成分,结合感官审评初步探讨了这些成分的香气品质特点。感官审评结果表明,千两茶香气以松木香、陈香为主要特点,部分千两茶香气略带粽叶香或粗老气、烟气、陈气味,个别千两茶略带酸味。GC-MS分析结果表明,香气物质相对含量最多的为醇类(9个样品平均相对含量为21.97%);其次为酮类(20.11%)、醛类(18.69%)、杂氧化合物(18.39%)、脂肪酸类(12.71%)、烷烃类(1.70%)、含量最少的是杂环类(1.21%)。可见对千两茶香气起主要作用的是醇类、酮类、醛类和杂氧化合物。

Abstract: Simultaneous distillation extraction (SDE) technique combined with gas chromatography-mass spectrometry (GC-MS) identification method were applied to analyze the volatile components in nine kinds of An-hua Qian-liang tea, in which, the aroma characteristic of the components were discussed by sensory evaluation method. Results of sensory evaluation indicated that the main features of An-hua Qian-liang tea are fragrance of pine wood and stale flavour. Some An-hua Qian-liang teas possess a slight fragrance of reed leaves and aroma of coarse stems as well as the stale flavour and smoke. A few An-hua Qian-liang tea possesses a little sour taste. Results of GC-MS analysis indicated that alcohols, ketones, aldehydes, heterocyclic oxygen compounds play a major role on An-hua Qian-liang tea aroma. The alcohol content is the largest (21.97%), followed by aldehydes (20.11%), ketones (18.69%), heterocyclic oxygen compounds (18.39%), fatty acids (12.71%), lipids (1.70%) and heterocyclic (1.21%) compounds.
