| 摘 要： | 采用顶空固相微萃取取法(HS-SPME),用气相色谱-质谱联用(GC-MS)技术分析了3个杨桃品种成熟果实的香气成分。结果表明,杨桃果实中的香气成分主要是乙酸-反-2-己烯酯、4,6,8-大柱三烯、β-紫罗兰酮、丁酸-反-2-己烯酯。此外还含有一些少量的1-壬醇、己酸-2-己烯酯、丙酸-反-2-己烯酯、丁酸-反-3-己烯酯、戊酸-反-2-己烯酯、茶螺烷、香叶基丙酮、苯甲酸甲酯、苯甲酸乙酯和乙酸辛酯等。不同品种的杨桃果实中的所含的香气成分及含量不同,B17杨桃含乙酸-反-2-己烯酯、丁酸-反-2-己烯酯、丁酸-反-3-己烯酯等青香型酯类最低而含β-紫罗兰酮、1-壬醇、乙酸辛酯苯甲酸甲酯、苯甲酸乙酯、茶螺烷等花香型、果香型及木香型成分最高,因而其香气品质要优于B10和新加坡红肉种。

| Abstract: | Aromatic constituents of 3 mature starfruit (Averrhoa carambola L.) cultivars, B17, B10 and Singapore Red, were analyzed using HS-SPME-GC-MS method.The main compounds were 2-hexen-1-ol acetate(z), 4,6,8-megastigmatrienes, β--Ionone and butanioc acid 2-hexenyl ester(E). In addition,there were also some special aromatic substances such as 1-nonanol, hexanoic acid 2-hexenyl ester, propanoic acid 2-hexenyl ester, butanioc acid 3-hexenyl ester(E)trans-2-hexenyl valerate, theaspirane, gerenylacetone, methyl benzoate and ethyl benzoate. Among 3 cultivars, B17 occupied the least green odor contents of aromatic constituents, such as 2-hexen-1-ol acetate(z) , butanoic acid 3-hexenyl ester (E) and butanoic acid 3-hexenyl ester(E), but had the most fruity, flowery and woody odors such as β-Ionone, 1-nonanol, Acetic acid octyl ester, Methyl benzoate, Ethyl benzoate and theaspirane, which showed that B17 was superior to the 2 other cultivars in aroma quality. |
