摘要/Abstract

摘要： 萎凋是红茶、乌龙茶等发酵茶加工的重要工序之一,对茶叶感官品质影响明显。萎凋过程中,随着水分的不断散失,鲜叶的呼吸作用持续进行,内质成分发生剧烈变化,促使萎凋叶物理特性发生改变,为后续工序和品质形成提供特定的物质和叶形基础。文章对萎凋过程中鲜叶的物理特性和生化成分变化规律,以及目前萎凋工艺关键参数的调控技术等进行了系统综述。可精准调控环境温度、湿度、光照、通气状况等参数的设施萎凋技术是今后萎凋技术发展的重要方向。

Abstract: The withering is an important process of fermented tea, such as black tea and oolong tea, significantly affected the sensory quality of tea. With water constantly lost in the withering process, the respiration of fresh leaf is carrying on continuously, the endoplasmic components are also dramatically changed and the physical characteristics of withering leaves are also prompted to change. All of these provided specific substances and leaves basis for the follow-up processes and the quality of finished tea. This paper illustrates the dynamic variation of the physical properties and biochemical components in the withering process, and conducted a systemic review on the regulation and control technology on the key parameters of current withering. The facility withering technology, which can accurately control these parameters including environment conditions, such as temperature, humidity, light conditions and aeration conditions, will become the important direction of withering development in the future.

Key words: withering, physical characteristics, biochemical composition, parameters regulation
