摘    要:采用顶空取样结合GC-MS 对蒜薹的挥发性风味成分进行了分析,结果表明,蒜薹中含有
23 种挥发性成分,其中含硫化合物15 种,相对含量为99.42%,主要成分为二烯丙基二硫醚(66.52%)、
1,3-二噻烷(15.44%)、二烯丙基三硫醚(7.15%)、二甲基二硫醚(1.24%)、二烯丙基硫醚(1.09%)和
2-烯丙基甲基三硫醚(2.66%)等6 种;与水蒸气蒸馏法相比,顶空取样检出的含硫化合物虽然种类少,
但相对含量高,且硫醚、多噻烷和硫代环己烯3 类主要成分都有检出。

关 键 词:蒜薹  挥发性风味成分  顶空取样  GC-MS  分析

Abstract:The volatile flavor components in garlic(Allium sativum L.) scape were analyzed by
using headspace sampling combined with GC-MS method.The results showed that garlic scape contains
23 kinds of volatile components,including 15 kinds of sulfur-containing compounds with 99.4% re lative
content.The 6 main components are diallyl disulfide( 66.52%),1,3-dithiane(15.44%),diallyl
sulfide(7.15%),dimethyl disulfide(1.24%),diallyl sulfide(1.09%) and 2-allyl methyl sulfide
(2.66%).Compared with steam distillation method,sulfur compounds detected by headspace sampling
method were fewer in kinds, but their contents were relatively higher,and the 3 main types ingredients
sulfide,multi-dithiane and thiocyclohexylene could be detected.
Keywords:Volatile flavor component  Headspace sampling  GC-MS analysis
