【摘要】 以晚熟荔枝品种"糯米糍"及其加工产品半干型荔枝干的各阶段样品为试材,采用顶空固相微萃取(HS-SPME)结合气质联用(GC-MS)对其香气化合物进行分析、鉴定和定量。新鲜荔枝和干燥第一阶段、第二阶段和半干型荔枝干成品各检测到36、45、47、45种香气化合物,其中烯类物质相对含量最高,分别为65.77%、63.95%、78.59%、63.00%。分析比较半干型荔枝干加工各阶段的香气成分变化。更多还原

【Abstract】 Aromatic components of fresh "Nuomici" litchi and semi-dried litchi during each drying stage were investigated by headspace solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS). Totally 36, 45, 47 and 45 aromatic components were identified in fresh litchi, the first drying stage, the second drying stage and semi-dried litchi final products, respectively. The highest relative content of aromatic components was alkenes in four samples, which were 65.77%, 63.95%, 78.59%, and 63.00%, respectively.更多还原
