摘要: 采用顶空固相微萃取法(SPME)结合气相色谱质谱联用技术(GC-MS),对干桂花窨制陈化龙井过程中的挥发物质进行检测。结果表明,高温蒸制可以改善茶叶的陈味,提高茶坯的含水量,利于花茶窨制,而常温吸湿干燥下的花茶品质好于低温烘干的花茶。

关键词: 陈茶, 桂花, 挥发性成分

Abstract: SPME and GC-MS was used to detect the volatile matter in the process of dry sweet-scented osmanthus scenting, to study the influence of pretreatment of high temperature steamed tea billet on the scenting effect and the effect of low temperature baking and moisture absorption drying on the flavor improvement of tea was explored by sensory evaluation. Through the high temperature steaming can improve the tea flavor, and improving the water content of tea billet is conducive to tea scenting system. The quality of scented tea of moisture absorption at normal temperature was better than that of low temperature drying.

Key words: aging green tea, osmanthus, volatile aroma
