摘要/Abstract

摘要： 为揭示黑茶发花过程中冠突散囊菌对茶叶中游离氟含量的影响,分别用出发菌株和诱变菌株对毛尖绿茶与黑毛茶进行纯种散茶“发花”,测定不“发花”茶叶、“发花”后去掉“金花”的茶叶、“金花”颗粒及液态发酵前后茶汤中的游离氟含量。结果显示：冠突散囊菌出发菌株与诱变菌株均使黑毛茶的游离氟含量升高,分别较不“发花”的对照茶样提高7.94%和10.47%,但均对毛尖绿茶的无影响;“金花”颗粒含一定量的游离态氟;冠突散囊菌能少量吸收茶汤中的氟,且吸收量与茶汤中游离氟的原始含量无相关性;冠突散囊菌对茶叶中游离氟含量的影响因茶叶的含氟水平不同而异,对氟无富集作用。

Abstract: For the purpose of revealing the influence of Eurotium Cristatum on content of free-state fluorine in tea , Eurotium Cristatum original strains and a mutant strain were used as pure strains during the fungus growing process of maojian tea(green tea) and raw dark green tea. Then the content of free-state fluorine in tea before and after the fungus growing process and in “Golden Flower” pellets were determined respectively. Also, the concentration of free-state fluorine in tea infusion before and after liquid fermentation with Eurotium Cristatum strain was determined. The results showed that both Eurotium Cristatum original strains and the mutant strain could increase the content of free-state fluorine in raw dark green tea by 7.94% and 10.47% respectively as compared with the tea that not inoculated the Fungi. But there was no influence on the content of free-state fluorine in maojian tea. “Golden Flower” pellets contained some free-state fluorine. Eurotium Cristatum strain could absorb a small amounts of free-state fluorine in tea infusion, but there was no dependency between absorptive amount and original concentration of free-state fluorine. Influence of Eurotium Cristatum strains on the content of free-state fluorine in tea was differed with the original level of fluorine in different tea, also, Eurotium Cristatum strains couldn’t concentrate the fluorine from environment.

Key words: Eurotium Cristatum, mutant strain, fu-brick tea, fluorine, free-state fluorine
