摘要:

利用顶空固相微萃取和气相色谱- 质谱联用分析技术,对春、秋两个季节栽培的3 个薹菜品种进行风味物质成分分析。共检测鉴定出了腈类、酯类、醛类、酮类、醇类等11 类化合物。其中(E)-2- 丁烯酸二乙酯、1-丁烯基-4- 异硫氰酸酯、2,4- 已二烯-1- 醇、3- 己烯-1- 醇、(E,E)-2,4- 己二烯醛、2- 己烯醛、3- 戊烯腈、苯丙腈和2- 苯乙基异硫氰酸是薹菜的主要风味物质。不同品种和不同的栽培季节薹菜的风味物质构成不同。

Abstract:

Headspace-solid phase microextraction (SPME) coupled to gas chromatography-mass spectrometry (GC-MS) was employed to analyze the volatile components in three Tai-tsai cultivars including Jingyan Taicai , Nanjing Xiaoye Taicai and Huaye Taicai grown in Spring or Autumn. Totally 11 kinds of volatile compounds such as alcohols, aldehydes, nitriles, ketones, esters, etc were identified. The predominant flavor compounds in Tai-tsai were (E)-2- butenedioic acid diethyl ester, 1-butene, 4-isothiocyanato-, 2,4-hexadien-1-ol, 3-hexen-1-ol, 2,4-hexadienal,(E,E)-, 2-hexenal, 3-pentenenitrile, benzenepropanenitrile and benzene, (2-isothiocyanatoethyl)-. Cultivar and growing season both may make a great contribution to the difference in volatile composition of Tai-tsai.

Key words: Tai-tsai, volatile components, GC-MS
