摘要
【目的】为研发出品质优良、质量稳定的桂林毛尖茶产品,促进桂林毛尖茶标准化生产及品牌建设。【方法】采用不同的加工工艺研制桂林毛尖茶,通过专业审评分析该加工工艺的特点及品质。【结果】不同摊青时间茶叶品质不同,得分最高为摊青4h,其次是摊青6h,摊青少于4h、高于6h时。滚筒杀青温度为220℃时,外形、香气、滋味最好;温度为200℃时,香气以清香为主;温度为240℃时,香气已带火工味。蒸气杀青温度为180℃~200℃时,茶叶品质最好,当蒸汽温度低于160℃时,茶叶易出现青气甚至杀不熟而造成红边红梗。烘干工艺若采用先低后高的温度设置,则初烘90±5℃、足干110±5℃处理品质最优;若采用先高后低的温度设置,则初烘110±5℃、足干80±5℃处理品质最优,采用先低后高的处理桂林毛尖茶叶干茶色泽更绿润,香气中嫩栗香发展更为显著。【结论】桂林毛尖茶生产的较佳技术路线为:鲜叶→摊青(4h^6h)→杀青(滚筒温度为:200~220℃;蒸汽杀青温度为:180~200℃)→揉捻(传统)→毛火(90±5℃)→足火(110±5℃)。
[ Objective ]In order to develop good and stable quality of Guilin Maojian tea products,promote the standardization production and brand construction of Guilin Maojian tea. [ Method ]Through the different processing technology development of Guilin Maojian tea, analysis the characteristics of the processing technology of green tea, [ Conclusion ]This study results show that, the better technical processing of Guilin Maojian tea is as follows: the fresh leaves 〉 booth filming for the green (4 - 6 h) - 〉 (roller temperature: 200 - 220 ℃; the filming for the steam temperature is: 180 - 200 ℃) and rolling (traditional) - (90 + 5 ℃) first drying - drying (110 + 5℃), which achieve good quality according to the comprehensive process.
