不同成熟期金太阳杏果实香气成分分析

采用静态顶空(SHS)固相微萃取和气相色谱-质谱(GC-MS)联用技术,对商熟期及完熟期的金太阳杏果实香气组分进行了测定。结果表明,金太阳杏的香气共47种,主要成分为醇类、醛类、酮类、酯类和酸类,但在果实不同成熟期,香气组成及含量差异很大。金太阳商熟期检测出33种成分,占总峰面积的82.37%,主要香气物质为乙酸己酯、乙酸-4-己烯-1-醇酯、二羟乙酸、6-甲基-5-庚烯基-2-酮、2-己烯-1-醇(E)、1,2-邻苯二甲酸二乙酯、2-(1-甲基乙基)-环己烯、3-己烯-1-醇(Z)、3,7-二甲基-1,5,7-辛三烯-3-醇、2,6,6-三甲基-1-环己烯-1-酮。完熟期共检出香气成分18种,占总峰面积的71.84%,主要包括顺-3-己烯-1-醇酯、二羟乙酸、乙酸己酯、10-苯-4,8-(甲基亚氨基亚甲基)萘-9,11-二酮、1,2,4-三甲基苯、萘、2-苯并噻吩。

Analysis of Fragrance in Golden - sun Apricot at Different Ripe Stage

The aroma components of Golden-sun apricot were studied at commercial ripe and tree ripe stage by HS-SPME(headspace solid phase microextraction) and GC-MS.47 compounds were identified and the main components were alcohols,aldehydes,esters,ketones and acids.The diversity of aroma constituents and content at different ripe stages were great.33 compounds were identified at commercial ripe stage,accounting for 82.37% of the total peak area.The main components are Acetic acid,hexyl ester;4-Hexen-1-ol,acetate;Glyoxylic acid;6-Methyl-5-heptene-2-one;(E)-2-Hexen-1-ol;1,2-Benzenedicarboxylic acid,diethyl ester;2-(1-methylethyl)-Cyclohexanol;(Z)-3-Hexen-1-ol;3,7-dimethyl-1,5,7-Octadien-3-ol;2,6,6-trimethyl-1-Cyclohexene-1-carboxal dehyde.18 compounds were identified at tree ripe stage,being 71.84% of the total peak area.The main components are(Z)3-Hexen-1-ol acetate;Glyoxylic acid;Acetic acid,hexyl ester;10-phenyl-4,8-(Methaniminomethano) naphthalene-9,11-dione;1,2,4-trimethyl-Benzene;Naphthalene;2-Benzothiophene.
