摘要:

采用同时蒸馏萃取法(SDE)和顶空固相微萃取法(HS-SPME)提取豆豉样品中挥发性成分,经气相色谱-质谱联用仪分析后共检测到96种挥发性化合物,其中烃类最多有40种,其次是酯类13种和醛类11种,另外醇类、酸类、酮类、酚类和杂环类分别有9、7、6、7、3种。SDE法和HS-SPME法分别鉴定出60种和43种风味组分,比较两种提取挥发性成分的方法可知,SDE法具有较高的萃取量,适合对高沸点、低挥发性的物质的分离;HS-SPME具有快速简便、不使用溶剂和样品检测非破坏性等优点,适合易挥发性化合物的检出。只有将两种方法结合起来,才能得到对产品的挥发性物质的综合评价。

Abstract:

Simultaneous distillation (SDE) and extraction method and head-space solid phase micro-extraction method (HS-SPME) were employed for sampling in GS-MS analysis of volatile components in commercial Douchi, respectively. Totally 96 compounds were identified, including 40 hydrocarbons, 13 esters and 11 aldehydes, 9 alcohols, 7 acids, 6 ketones, 7 phenols and 3 other heterocycles. There were more components extracted with SDE than those with HS-SPME, and SDE method provided better results in detecting high boiling-point and low volatile compounds, while SPME method was more rapid, simple, and nondestructive. A comprehensive evaluation on volatile components in Douchi products could be obtained by the combination of both methods.
