摘要: 采用顶空气相离子迁移谱(gas chromatography-ion mobility spectroscopy,GC-IMS)技术对新疆环塔里木盆地3 个红枣主产区、河南新郑和山西临县31 个不同产地枣果特征风味成分进行分析。通过构建枣果GC-IMS风味指纹图谱,对比明显,可以直观看出不同产地枣果挥发性有机物的差异。新疆各产地灰枣和骏枣与其原产地枣果挥发性风味物质差异明显。与骏枣相比,灰枣中对香气贡献最大的挥发性有机物主要有1-辛烯-3-醇(D)、2-甲基丙酸、3-辛酮(D)、丁酸、羟基丙酮等物质;而骏枣中对香气贡献最大的挥发性有机物主要有丙醛、2-丙酮、3-甲基丁醛、辛醛(M)、壬醛(M)等物质。

Abstract: Gas chromatography-ion mobility spectrometry (GC-IMS) was used to analyze the characteristics and flavor components of 31 jujube samples from three major production areas around the Tarim Basin in Xinjiang autonomous region, Xinzheng in Henan province and Linxian in Shanxi province. GC-IMS flavor fingerprints were constructed to visually identify the differences in the volatile organic jujubes from different geographical origins. The volatile flavor compounds of Huizao and Junzao jujubes from the regions in Xinjiang were significantly different from those of the jujubes from their native habitats. 1-Octene-3-ol (D), 2-methylpropionic acid, 3-octanone (D), butyric acid, and hydroxyacetone contributed the most to the aroma of Huizao jujube. The volatile organic compounds that contributed the most to the aroma of Junzao jujube were propanal, acetone, 3-methyl butyral, octanal (M), and nonanal (M).

Key words: jujube; gas chromatography-ion mobility spectrometry; volatile organic compounds; fingerprints
