香草兰豆荚发酵过程中挥发性成分的变化

Changes of Volatile Compounds in Vanilla Beans during Curing Process

  • 摘要: 为研究香草兰发酵过程中挥发性成分的累积过程,采用了混合溶剂(乙醚/正戊烷=1:1,v/v)提取结合GC-MS的方法进行定性定量分析,并以DB-5及DB-Wax两种毛细管柱为分离柱分别进行了实验。结果表明:以DB-5毛细管柱为分离柱时,检测出45种挥发性物质,鲜豆荚、杀青豆荚、发汗豆荚、干燥豆荚及陈化豆荚分别检测出19、17、25、33、37种挥发性成分;以DB-Wax毛细管柱为分离柱时,检测出53种物质,五种豆荚中分别检测出20、21、27、38、46种挥发性成分。两种方法共分离检测出69种物质。挥发性成分主要在干燥及陈化阶段产生并累积,其中含量逐渐增加且在陈化豆荚中含量较高的有乙酸、愈创木酚、香兰醇、十六酸等物质,反式-2-癸烯醛、硬脂酸甲酯、山嵛醇等物质仅出现在发酵前期,己二酸二(2-乙基己)酯、2-乙基己基乙酸酯的含量在发酵过程中逐渐降低。成熟豆荚的香气是由多种前体物的代谢产物混合而形成。

     

    Abstract: In order to analyze the accumulation of volatile components in vanilla beans during the curing process,volatile compounds in vanilla beans were extracted using organic solvents and quantitated by gas chromatography-mass spectrometry(GC-MS)with DB-5 and DB-Wax capillary column. The results indicated that 45 volatiles were detected with DB-5 for separation,and 19,17,25,33,37 components were identified in fresh vanilla bean(FVB),blanched vanilla beans(BVB),sweated vanilla beans(SVB),dried vanilla beans(DVB)and cured vanilla bean(CVB),respectively. Using DB-Wax for separation 20,21,27,38,46 volatile components were detected of vanilla beans at different curing stages. A total of 69 volatile compounds were detected in vanilla beans. Among them,acetic acid,guaiacol,vanillyl alcohol,n-hexadecanoic acids were with high content and increased during curing.(E)-2-decenal,octadecanoic acid methyl ester,behenic alcohol only appeared in earlier stages. Hexanedioic acid bis(2-ethylhexyl)ester and octyl acetate decreased during curing. The aroma of cured vanilla beans was formed by the mixing of metabolites of various precursors.
