中文摘要: 为探索文冠果叶茶与花茶加工风味变化差异,利用气相色谱-离子迁移(gas chromatography-ion mobility spectrometry,GC-IMS)法对文冠果鲜叶、叶茶、花茶中挥发性成分进行测定。结果表明,共检测出酮类、醛类、醇类、酯类、萜烯类等83种挥发性成分,鉴定出41种。文冠果鲜叶中酯类含量最高,叶茶中酮类含量最高,花茶中醛类含量最高。加工处理对各种茶的挥发性物质成分影响较大且表现不一,鲜叶加工后各类挥发性成分减少为原体积的55.48%~61.05%,其中酮类相对稳定、酯类减少最多;叶茶中正丁醇、(E)-β-罗勒烯等23种物质含量降至鲜叶含量的20%以下,而2-乙酰基呋喃、2,3-丁二醇、3-(甲基硫代)丙醛等含量提升。叶茶与花茶相比,叶茶中丁酮、乙酸叶醇酯、2,3-丁二醇及壬醛含量更高,花茶中过氧化乙酰丙酮、(2E,4E)-2,4-辛二烯醛等10种物质含量更高。
