摘要
根据不同原料、不同含水量和水浸出物含量的茶坯的一系列研究结果 ,论述了茉莉花茶湿窨机制 :高含水量茶坯中的水和水浸出物是化学吸附的载体 ;水浸出物直接影响茶坯对香气物质吸附的选择性 ;茶坯水分是增强化学吸附 ,提高吸香能力和保香效果的基础 ,并参与窨制过程的良性循环 .花茶窨制中化学吸附与物理吸附并存 ,两种作用无明显界限 ,但可能有强弱之分 .
According to a series of reseaches on various raw materials,moisture contents and water extract in tea leaves,the mechanism of wet scenting shows that water in tea leaves with high moisture contents and water extract are the carrier of chemical absorption; water extract directly affects the selection of aromatic material absorption by tea leaves; moisture in tea leaves is the base of strengthening chemical absorption,enchancing both the ability of absorbing aroma and the effects of keeping aroma; it also works in the benign circle of scenting process. In the process,there exists both chemical absorption and physical absorption simultaneously.Although there is no clear dividing line between the two types of absorptions, there is a difference of intensity between them. It was proved by experiments that there is chemical reaction in the process of wet scenting.
