【摘要】 采用顶空固相微萃取对塔罗科血橙汁的香气成分进行提取,用气相色谱-质谱对香气化合物进行分析,结合谱库检索技术和保留指数对化合物进行鉴定,应用峰面积归一化法测定各成分的相对含量,共鉴定出39种香气成分,相对总量为87.23%。主要香气成分为烃类(55.13%),酯类(13.67%)、醇类(13.17%)、醛类(4.59%),还有2种酮类(0.67%)。其中相对含量最高的是柠檬烯(50.40%),其次是丁酸乙酯(7.67%)、乙醇(5.38%)、3-羟基己酸乙酯(3.92%)、己醛(3.73%)、芳樟醇(3.32%)、β-月桂烯(1.87%)、α-松油醇(1.50%)、巴伦西亚桔烯(1.50%)、己酸乙酯(1.07%)。更多还原

【Abstract】 The aroma components from Tarocco blood orange juice were extracted by solid phase microextraction. The aromatic compounds were analyzed by GC-MS and identified by mass spectra and retention indices. There were 39 compounds identifiedand the percent of the total peak areas was 87.23%. The major constituents are: hydrocarbons 55.13%, esters 13.67%, alcohols 13.17%, aldehydes 4.59% and ketones 0.67%. Limonene is of the highest content 50.40%, followed by ethyl butanoate 7.67%, ethanol 5.38%, ethyl 3-hydroxyhexanoate 3.92%, hexanal 3.73%, linalool 3.32%, β-myrcene 1.87%,α-Terpineol 1.50%, valencene 1.50%, and ethyl hexanoate 1.50%.更多还原
