2、固相微萃取法对桂葡3号葡萄浆果的挥发性成分进行富集,利用气相色谱一质谱联用(GC.MS)对其挥发性成分进行定性定量分析,并应用香气活性值(OAV)法对其活性香气成分和特征香气成分进行鉴定分析。【结果】从桂葡3号葡萄浆果中共鉴定出39种挥发性成分,包括醇、酯、醛、酮、萜烯类等成分,挥发性成分总含量为32mg/kg,其中含量较高的成分有4.羟基.2.丁酮、丁酸乙酯、己醛、2一丁烯酸乙酯、己酸乙酯和丙酸乙酯;39种挥发性成分中共鉴定出17种活性香气成分,其中特征香气成分有丁酸乙酯、2一丁烯酸乙酯、异丁酸乙酯、己酸乙酯、己醛、4.羟基-2一丁酮
3、和戊酸乙酯,构成以果香、脂香、青香和玫瑰香为主体香韵的香型特征。【结论】桂葡3号葡萄特征香气成分含量丰富、种类较多、香气清新,适宜酿造新鲜消费型干白或甜白型葡萄酒。关键词:桂葡3号葡萄;挥发性成分;特征香气成分;GC—MS;OAV法中图分类号:TS261.2文献标志码:A文章编号:2095—1191(2015)05—0871-05AnalysisofcharacteristicaromacomponentsinGuipuNo.3grapepulpZHANGJinl,QINXiao—yuan2,YANGYing1,XIETai-lil,G
