【摘要】 采用顶空固相微萃取对血橙的香气成分进行提取,用两个不同极性的色谱柱(HP-5和DB-WAX)进行分离,利用气相色谱-质谱联用技术对香气成分进行分析。在DB-WAX柱上鉴定出32种组分,HP-5柱共鉴定出45种主要化合物,占总峰面积的71.96%,主要成分为:柠檬烯(56.6%)、乙醇(4.24%)、巴伦西亚桔烯(2.06%)、β-月桂烯(1.73%)、丁酸乙酯(0.92%)、反式-2-己烯醛(0.75%)。HP-5柱更适合血橙香气成分的分离。更多还原

【Abstract】 The aroma components of blood orange fruit were extracted by headspace solid phase microextraction and investigated by gas chromatography-mass spectrometry with two GC columns of different polarity(HP-5 and DB-WAX).32 compounds were identical with the compounds separated on DB-WAX column.45 major volatile compounds were identified on HP-5 column,which accounted for 71.96% of total peak areas.The main components are limonene(56.6%),ethanol(4.24%),valencene(2.06%),β-myrcene(1.73%),ethyl butanoate(0.92%),(E)2-hexenal(0.75%).The HP-5 column is more suitable for separation of aroma compounds in blood orange fruit.更多还原
