摘要
[目的]了解河源火蒜与普通蒜的香气成分差异。[方法]采用静态顶空进样－气相色谱－质谱联用法（ SHS－GC－MS）对河源独头火蒜和独头蒜的挥发性物质及含量进行分析。[结果]该试验条件下，共检出独头蒜挥发性风味成分主要有23种，12种为含硫化合物，其中主要成分是二烯丙基三硫醚（25．11％）、二烯丙基二硫醚（19．78％）、3，4－二甲基－1，2－二硫环戊烯酮（18．65％）、二氧化硫（5．20％）、3－乙烯基－1，2－二硫环戊烯（2．61％）、烯丙基甲基硫醚（2．31％）、2－乙烯基－1，3－二噻烷（2．07％）、2－恶唑烷硫酮（2.00％）、甲硫基乙腈（1．78％）、硫氰酸乙酯（1．28％），共占总含量81．73％；共检出独头火蒜主要挥发性风味成分也为23种，14种为含硫化合物，其中主要成分是二烯丙基三硫醚（38．03％）、二烯丙基二硫醚（22．63％）、3－乙烯基－1，2－二硫环戊烯（7．95％）、3，4－二甲基－1，2－二硫环戊烯酮（7．55％）、二氧化硫（4．08％）、甲硫基乙腈（4．04％）、二烯丙基硫醚（2．99％）、异硫氰甲酸甲酯（2．08％）、硫氰酸乙酯（1．49％）、烯丙基甲基硫醚（1．41％）、硫化丙烯（1．25％）、2－乙烯基－1，3－二噻烷（1．15％），共占总含量95．59％。[结论]河源独头火蒜的挥发性物质的数量和含量比普通独头蒜都高。
Abstract
Objective]To understand the difference of aroma components of Heyuan toasted garlic and clove garlic.[Methods] Static head-space -gas chromatography -mass spectrometry (SHS-GC-MS) analysis method was applied.[Results] Under the experimental conditions, 23 kinds of volatile components were detected in single clove garlic , 12 kinds were sulfur-containing compounds in which the main ingredients were Diallyl trisulfide (25.11%), diallyl disulfide (19.78%), 3,4-dimethyldithiol-2-one (18.65%), sulfur dioxide (5.20%), 3-ethenyl-1,2-dihydrodithiine (2.61%), allyl methyl sulfide (2.31%), 2-vinyl-1,3-dithiane (2.07%), 2-oxazolidine-thione (2.00%), methylthio acetonitrile (1.78%), and ethyl thiocyanate (1.28%) accounting for 81.73% of the total content.In addition, 23 species were detected in single toasted garlic, 14 kinds were sulfur-containing compounds in which main ingredients were diallyl sulfide (38.03%), diallyl disulfide (22.63%), cyclopenten-3-vinyl-1,2-dithiol (7.95%), 3,4-dimethyl-1,2-disulfide cyclopentenone (7.55%), sulfur dioxide (4.08%), methylthio acetonitrile (4.04%), diallyl sulfide (2.99%), methyl isothiocyanate (2.08%), ethyl thiocyanate (1.49%), allyl methyl sul-fide (1.41%), propylene sulfide (1.25%), and 2-vinyl-1,3-dithiane (1.15%), accounting for 95.59%of the total content.[Conclusion] The number and content of flavor substances in Heyuan clove garlic are higher than ordinary single garlic .
