摘  要:
用GC/MS法分析了黄旦品种乌龙茶的香气组分,并对不同湿度做青环境条件下生产的乌龙茶香气组分进行比较分析表明:黄旦乌龙茶主要香气成分为橙花叔醇、α-法呢烯、芳樟醇及其氧化物、香叶醇、苯乙醛、吲哚、顺-茉莉内酯、β-紫罗酮+顺-茉莉酮、乙酸苄酯等;在相同温度(23℃),不同湿度做青环境生产的黄旦乌龙茶香气主要特征成分含量和精油总量各不相同,且香气品质以做青环境相对湿度75%为好,香气高且持久。说明做青环境是影响乌龙茶香气的重要因素之一。

摘  要:
Aromatic constituents of Huangdan Oolong tea were analysed with GC and MS and were compared in different green\|making humid conditions.The major aromatic constituents of Huangdan Oolong tea were nerolidol, α\|farnesene, linalool and its oxide, geraniol, pheny lacetal dehyde, indole, cis\|jasmine lactone β\|ionone + cis\|jasmone, benzyl acetate and so on.At the same temperature,the content of aromatic constituents were different, the aromatic quality in the 75% humid condition was better,which was more fragrant and kept longer.It proved that the green\|making humid condition was one of the major factors to effected aroma of Oolong tea.
