摘要
采用固相微萃取法(SPME)对苦荞茶和苦荞糊中的挥发性香气成分进行提取,并经气相色谱-质谱联用(GC-MS)技术定性分析。从苦荞茶和苦荞糊中分别检测出30种和41种挥发性香气成分,相同成分有15种,其中含量较高的是烃类、醛类和杂环类,三者在苦荞茶和苦荞糊中含量分别为24.56%、35.04%、18.42%和46.97%、21.22%、7.22%。研究表明,顶空固相微萃取具有快速简便、不使用溶剂和样品检测非破坏性等优点,结合气-质联用技术可以很好的分析苦荞产品中挥发性物质,并说明不同加工工艺制得的苦荞产品其挥发性物质存在一定差异。
The volatile aroma components in tartary buckwheat tea and tartary buckwheat paste were extracted by solid phase microextraction（SPME）technique and determined by GC-MS. Thirty volatile compounds were isolated and identified from tartary buckwheat tea, and forty-one compounds from tartary buckwheat paste, in which fifteen compounds were common to both. The contents of hydrocarbons, aldehydes and heterocyclic compounds were 24.56%, 35.04%, 18.42% in tartary buckwheat tea and 46.97%, 21.22%, 7.22% in tartary buckwheat paste, respectively. The study showed that SPME method provided a good result combing with GC-MS in detecting volatile compounds of tartary buckwheat products with advantages of rapid,simple, and non-destructive, and there were some differences in volatile substances of buckwheat products with different processing technology.
