摘  要:
[目的]确定都匀毛尖冲泡的最佳工艺条件,以指导其科学的饮用和发挥最佳预防保健作用。[方法]选取液固比、冲泡温度、冲泡时间和冲泡次数为考察因素,以都匀毛尖中茶多糖的得率为评价指标,采用正交试验对其冲泡工艺进行优选。[结果]影响都匀毛尖茶多糖提取的因数顺序为:液固比>冲泡温度>冲泡时间。最优冲泡工艺参数为液固比80∶1 ml/g,冲泡温度90℃,冲泡时间10min,冲泡2次。[结论]研究得出的都匀毛尖冲泡的最优工艺经验证为科学的、合理的。

摘  要:
[Objective] To confirm the optimal brewing process of Duyun Maojian,and guide its scientific drinking and make full advantage of its health care functions.[Method] Water-tea ratio,brewing temperature,brewing minutes and brewing times are chosen as the assessment index.Orthogonal design was used for the optimization of extraction process with the polysaccharides yield as the evaluation criteria.[Result] The influential order of each factor on the polysaccharides extraction from Duyun Maojian was as the following: water-tea ratio>brewing temperature>brewing time.The results show that the best brew parameters are 80∶1 ml/g of water-tea ratio and 90 ℃ of brewing temperature for 10 min and for twice.[Conclusion]The best brewing parameters of Duyun Maojian tea are proved to be scientific and reasonable.
