摘  要:
以不同采收期的南果梨为材料,用顶空固相微萃取(headspace-solid phase microextraction,HS-SPME)结合气质联用(gas chromatogaphy-mass spectrometry,GC-MS)技术对完熟果实的香气进行研究。结果表明,不同采收期果实的香气组成和含量均有一定差异,尤以特征香气的差别较大。早采果实的特征香气主要有丁酸乙酯、2-甲基-丁酸乙酯、己酸乙酯、乙酸己酯、己醛和癸醛,而晚采果实比早采收果实多了乙酸丁酯和2-己烯醛两种特征香气。晚采果实表现出较浓的果香味,而早采果实中除果香味外,还有一定的青香味。

摘  要:
The aroma composition of fully ripe Nanguo pear fruits harvested at different times were determined by headspacesolid phase microextraction gas chromatogaphy-mass spectrometry(HS-SPME-GC-MS).The results showed that the composition and contents of aromatic compounds in fruits harvested at different times were different,especially for characteristic aroma.Early harvested fruits had characteristic aroma components including ethyl butyrate,2-methyl ethyl butyrate,ethyl hexanoate,hexyl acetate,hexanal and decanal;in contrast,late harvested fruits had butyl acetate and 2-hexenal as additional characteristic aroma components.Moreover,late harvested fruits had strong fruity aroma,however,early harvested fruits had fruity aroma coupled with little grassy aroma.
