中文摘要：为研究辛香型香辛料的香气活性成分,推进其加工和应用标准化进程,本实验利用溶剂辅助风味蒸发法分离提取香辛料的挥发性香气成分,结合气相色谱-质谱/嗅闻技术对20种辛香型香辛料的香气活性成分进行定性定量分析.基于嗅闻分析,在香辛料样品中共嗅闻到203种香气活性化合物(香气稀释因子≥9),主要由醇类、含硫类化合物、烯烃类、酯类、酮类、醛类、酚类、酸类组成,不同种类香辛料的香气活性成分含量存在差异.进一步进行主成分分析,所有样品可以很好地划分为3组.大蒜、大葱、小葱、洋葱的香气活性成分以含硫类化合物为主,其余香辛料的香气活性成分以烯烃类、醇类、酚类、酮类为主.含硫类香气活性成分在大蒜中检出含量最高,为3 484 777.68 μg/kg,在大蒜中检出多种具有葱属植物风味特征的二硫醚、三硫醚等含硫类化合物;烯烃类香气活性成分在姜中检出含量最高,为72 847 224.14 μg/kg,检出姜的主要香气成分α-姜烯、β-倍半水芹烯等:醇类香气活性成分和酮类香气活性成分在野薄荷中检出含量较高,分别为284 886.09μg/kg和196 167.66 μg/kg,检出野薄荷的特征香气成分薄荷醇、香芹酮;醛类香气活性成分在木姜子中检出含量较高,为469 242.68 μg/kg,检出木姜子的主要香气成分柠檬醛、香茅醛等.本研究解析了辛香型香料的关键香气成分,为其精深加工提供一定的理论依据.

外文标题：Characterization of the Aroma-Active Compounds in 20 Pungent Spices by Solvent-Assisted Flavor Evaporation Combined with Gas Chromatography-Mass Spectrometry/Olfactometry

外文摘要：In order to study the aroma-active components of pungent spices and to promote the standardization of their processing and application,this work used solvent-assisted flavor evaporation(SAFE)combined with gas chromatography-mass spectrometry/olfactometry(GC-MS/O)to qualitatively and quantitatively analyze the aroma-active components of 20 pungent spices.Using olfactory analysis,a total of 203 aroma-active compounds with flavor dilution(FD)values＞9 were identified mainly consisting of alcohols,sulfur compounds,olefins,esters,ketones,aldehydes,phenols and acids,and the concentrations of aroma-active compounds varied between different spices.Principal component analysis(PCA)showed that all samples could be well classified into three groups.The aroma-active compounds of garlic,Welsh onion,chive and onion were dominated by sulfur compounds,while the aroma-active components of the other pungent spices were dominated by olefins,alcohols,phenols and ketones.Aroma-active sulfur-containing compounds were detected in garlic at the highest level of 3 484 777.68 μg/kg,including disulphide and trisulphide,contributing to the characteristic flavor of Allium plants.The highest content of aroma-active olefinic compounds of 72 847 224.14 μg/kg was detected in ginger,and the major aroma-active components of ginger were α-gingerene and β-sesquiterpene.Alcohols and ketones were detected in wild mint at high levels of 284 886.09 and 196 167.66 μg/kg,respectively,and the characteristic aroma components of wild mint were menthol and carvone.Aroma-active aldehydes were detected in litsea at high levels of 469 242.68 μg/kg.The major aroma-active components detected in litsea were citral and citronellal.This study provides a theoretical basis for the deep processing of pungent spices.
