广西茶树品种“桂红3号”制作花香型工夫红茶试验初探

Preliminary study on the test of flowery type Gongfu black tea made by Guangxi tea tree variety "GuiHong No.3"

【目的】为顺应市场的变化,充分发挥“桂红3号”的优势与作用,开发独具广西特色的红茶产品,加快“桂红3号”应用推广步伐提供技术支撑。【方法】试验针对“桂红3号”的特征特性,采用不同萎凋工艺、不同发酵时间及不同干燥温度作对比试验,在每个环节对比试验后,选出较佳参数,再以这个参数进行下一步环节对比试验。每个环节均设3个重复,以确定各工艺环节较佳工艺参数。【结果】萎凋工艺以晒青40min处理的萎凋花香浓郁持久,汤色红艳透亮,滋味甜醇花香浓;在发酵环境温度为25℃,发酵叶湿度为80%条件下,发酵时间为4h时,花香浓郁;在干燥过程中,毛火90℃（5min）处理茶汤的花香明显;在干燥工艺中,毛火90℃（5min）处理茶汤的花香明显。【结论】“桂红3号”花香型工夫红茶的较佳加工工艺为：鲜叶采收→萎凋（晒青40min,空调设置温度25℃,相对湿度70-80%）→揉捻→解块→发酵（发酵环境温度为25℃,相对湿度为80%条件下发酵4.0h）→干燥（毛火90℃5min,足火100℃至足干）

[ Objective ]In order to comply with the changes in the market, give full play to the advantages and the role of ＂GuiHong No.3＂, developing the unique characteristics of Guangxi tea products, and provide tech- nical support for speeding up the pace of ＂GuiHong No.3＂ application and promotion. [ Method ]Conducted contrast contest, according to the characteristics of the ＂GuiHong No.3＂, adopting different wilting technology, fermentation time and drying temperature for contrast test, after the comparison experiments of each step, the better parameters are selected, then move to the next step by applying in this parameter. Each step set three repetition, to determine the better process parameters for the process; [ Result ]The test results show that, for the sun withering processes, after 40 min treatment, the fragrant rich lasting, the color of tea soup is brilliant red, taste sweet and concentration;under the conditions of fermentation, when temperature is 25℃, leaf humidity is 80% , the fermentation time is 4 h, the smell is rich of flower fragrant;In the process of drying, the treatment of first drying in 90 ℃ （5 rain）, the smell of tea soup is flower fragrant significantly;[ Conclusion ] The better treatment technology for Guangxi tea tree variety ＂GuiHong No.3＂ of flowery type Gongfu black tea is as follows： collect the fresh leaves, then withering harvested （40 rain sun withering, air conditioning setting temperature 25℃, relative humidity 70 - 80%） and rolling to deblocking, fermentation （ the fermentation temperature is 25℃, relative humidity 80% under the conditions, for fermentation 4.0 h） and dry （first drying in 90 ℃ for 5 min, sufficient fire 100℃ to foot dry）
