| 摘 要： | 通过顶空固相微萃取结合气相色谱质谱联用技术分析油红梨果实后熟不同时期挥发性组分。后熟0d、5d及10d时分别检测出11、26和33种挥发性成分，主要为酯类、醛类、醇类及萜类物质。各种挥发性物质在不同的后熟时期种类及绝对含量均为升高的趋势，尤其是酯类组分的增加；35种挥发性组分中共检测出7种特征香气组分，分别为己醛、E-...

| Abstract: | The volatile components of Youhongli(Pyrus ussuriensis Maxim.) in different ripening stages were extracted by headspace solid phase micro-extraction and analyzed by gas chromatography-mass spectrometer.Eleven,twenty-six and thirty-three components mainly including aldehydes,esters,alcohols and terpenes were identified at different ripening stages.The number and concentration of different volatile profiles,especially esters increased with the development of ripening.Seven characteristic impact compounds including hexanal,E-2-hexenal,ethyl butanoate,ethyl 2-methylbutanoate,ethyl hexanoate,hexyl acetate and ethyl heptanoate were identified amongst these 35 volatiles.Ethyl 2-methylbutanoate,ethyl hexanoate and hexyl acetate had the highest aromatic values.Based on the volatiles,electronic nose could clearly discriminate different ripening stages of Youhongli pear. |
