二次渥堆对安化黑毛茶品质形成的影响研究

Study on the second pile- fermentation on quality formation of Anhua dark green tea

  • 摘要: 通过设置茶胚的含水量、渥堆时间和空气湿度这三个渥堆工艺条件,在实验室条件下进行二次渥堆正交实验,探讨二次渥堆对黑毛茶品质形成的影响和机理,确定二次渥堆的最佳工艺条件。理化分析表明在二次渥堆中,茶多酚、儿茶素、氨基酸、咖啡碱、可溶性糖、水浸出物的含量均呈减少趋势,黄酮的含量变化不明显;结合感官审评结果确定在茶胚含水量10%的基础上,含水量应为35%,渥堆时间30 h,空气湿度85%的二次渥堆工艺条件最好。 

     

    Abstract: To study the effect of second pile- fermentation on quality formation of Anhua dark green tea and make sure the best processing conditions,the research simulated an orthogonal test of the second pile- fermentation under the laboratory conditions by setting up the processing conditions about water contents,pile- fermentation time,air humidity.The physical and chemical analysis showed that in the process of the second pile- fermentation,the contents of tea polyphenols,catechins,amino acids,caffeine,water- soluble sugar and water extract all were decreased while the flavones was changed not significant.Combining with sensory evaluations,the results showed that with 35% water contents,30 hours pile—fermentation time,85% air humidity was the best condition for second pile- fermentation.
