温控炭焙结合传统炭焙的优点,并结合现代温度控制技术,对于保持茶叶品质的稳定和高效利用能源具有重要作用。采用武夷岩茶为材料,在130℃、120℃和110℃温度下分别烘焙6h,分析不同炭焙温度对武夷岩茶水仙感官品质、主要理化成分的影响。结果表明:以温控炭焙130℃6h处理的茶样感官审评得分最高。氨基酸、茶多酚、咖啡碱含量呈下降趋势,水浸出物含量差异不显著。汤色RGB值CK处理最大,A3处理最小。
Combining with the advantages of traditional charcoal baked and modern temperature conl technolo- gy, the temperature control charcoal baked plays an important role in maintaining the stability of tea qua ity and im- proving the use of energy efficiently. Chosing Wuyi rock tea as the material, and baking for 6 hours at the tempera- tures of 130℃, 120℃ and ll0℃. Then Analyzing the effect on qualities and the main biochemical components of Wuyi Rock tea at different carbon baking temperatures. The result shows that: Baked with the temperatu re of 130℃ for 6 hours get the highest score by sensory evaluation ; and the content of the amino acids, tea polyphenpls and caf- feine is decreased when baking temperature is enhanced, and the difference in water extract content is unsignifi- cant. The RGB ( Red, Green, Blue) value of liquor color, CK maximum, A3minimum.
