摘要
[目的]分析六堡茶的主要理化指标成分,并与其他茶类比较,探索六堡茶的品质特征和地方特色。[方法]对地理标志产品六堡茶中的水分、总灰分、茶梗、水浸出物(干态)等理化成分进行分析,并与工夫红茶、大叶种绿茶、茯砖茶、普洱茶(熟茶)国标中的技术要求限量等进行比较。[结果]采集茶样中的总灰分与工夫红茶、大叶种绿茶的最高限量值接近,比六堡茶国标中的最高限量值低31.4%,水浸出物含量平均水平比国标中绿茶最低限量值要求高18.4%,比红茶(大叶)和其他类别的紧压茶(花砖茶)最低限量值要求高出33.0%、93.7%,结合水分与茶梗的特点,得出特殊的地理环境和生产工艺形成了六堡茶独特的滋味和风味。[结论]应通过地理标志保护制度发挥地理标志产品六堡茶的特色特点,促进产业的发展。
[Objective]The main physical indexes of Liupao tea ingredients were analyzed,and compared with other teas,Liupao tea quality characteristics and local characteristics were explored. [Method]The content of water,total ash,water extracts,tea stalk( dry) and other chemical components in the geographical indication products Liupao tea were analyzed,And with time,Congou black tea,Dayezhong green tea,Fuzhuan Tea,Pu'er Tea( tea) requirements in the national standard of technology limited. [Result]The total ash content in tea samples was close to the maximum ash content in Congou black tea and Dayezhong green tea. The maximum limit value was 31. 4% lower than the national standard of Liupao tea,the average level of water leach content was 18. 4% higher than that of green tea in the national standard. The lowest limit value was 93. 7%,33. 0% higher than Black Tea( Daye) and other categories of tea( flower tea),According to the characteristics of water and tea stalk,formed a unique flavor and taste of tea that the special geographical environment and production process. [Conclusion]It should play the characteristics of geographical indication products of Liupao tea by geographical indications protection system,promote the development of the industry.
