摘要: 采用顶空固相微萃取法对费约果果实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32种香气成分,相对总量为90.29%。主要香气成分为酯类(50.64%)、醛类(26.04%)、醇类(5.84%)、烯类(3.85%)、酮类(3.14%),酚类(0.77%)。其中相对含量最高的是苯甲酸甲酯(36.56%),其次是顺-3-己烯醛(17.44%)、已醛(5.07%)、丁酸乙酯(4.21%)、乙醇(3.60%)、反-2-己烯醛(3.53%)、苯甲酸乙酯(1.50%)、3-辛酮(1.44%)、芳樟醇(1.40%)、丁酸顺式-3-己烯酯(1.30%)、乙酸乙酯(1.21%)、石竹烯(1.04%)。

Abstract: Aroma components were extracted from feijoa by solid phase microextraction. The aromatic compounds were analyzed by GC-MS and identified by library search for mass spectrum. There are 32 compounds identified and the percent of total peak area is 90.29%. The major constituents are esters 50.64%,aldehydes 26.04%,alcohols 5.84%,hydrocarbons 3.85%,ketones 3.14% and phenol 0.77%. Methyl benzoate is of the highest content 36.56%,followed by(Z)-3-hexenal 17.44%,hexanal 5.07%,ethyl butanoate 4.21%,ethanol 3.60%,(E)-2-hexenal 3.53%,ethyl benzoate 1.50%,3-octanone 1.44%,linalool 1.40%,(Z)-3-hexenyl butanoate 1.30%,ethyl acetate 1.21%,and caryophyllene 1.04%.
