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%)。
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%.
