摘要/Abstract

摘要：

通过测定并比较由8个品种(茂绿、翠峰、龙井43、迎霜、福鼎大白茶、鸠坑种、白叶1号、薮北种)茶树春季和秋季鲜叶制成的超微绿茶粉的粒径参数、色差数值和内含成分,联合感官审评结果,以期筛选出适制超微绿茶粉的茶树品种和采制季节。结果表明,由龙井43春茶制成的超微绿茶粉粒径最小,由翠峰春茶制成的超微绿茶粉颗粒最均匀;由翠峰春茶和福鼎大白茶春茶制成的超微绿茶粉色泽最纯净艳丽;由福鼎大白茶春茶和龙井43春茶制成的超微绿茶粉氨基酸含量最高,而茶多酚和水浸出物含量较低;由薮北种春茶、迎霜秋茶和福鼎大白茶秋茶制成的超微绿茶粉审评总得分最高。综合分析后认为,龙井43、翠峰、福鼎大白茶和薮北种茶树的春茶适制超微绿茶粉,迎霜和福鼎大白茶的秋茶可用于制作饮用型超微绿茶粉。

Abstract:

In the present study, the particle size parameters, chromatic aberration and component contents of ultramicro green tea powder made from fresh spring and autumn leaves of eight tea cultivars (Maolv, Cuifeng, Longjing No. 43, Yingshuang, Fudingdabaicha, Jiukengzhong, Baiye No. 1, Soubeizhong) were determined and compared. Sensory evaluation was also used to select the suitable tea cultivars and harvest season. It was shown that the particle size of ultramicro green tea powder made from Longjing No. 43 spring tea was the smallest, and the particle size of ultramicro green tea powder made from Cuifeng spring tea was the most uniform. The ultramicro green tea powder made from Cuifeng spring tea and Fudingdabaicha spring tea had the most pure and gorgeous color. The amino acids content of ultramicro green tea powder made from Fudingdabaicha spring tea and Longjing No. 43 spring tea was the highest, while their tea polyphenols and water extract contents were relatively low. The sensory evaluation result showed that, the ultramicro green tea powder made from Soubeizhong spring tea, Yingshuang autumn tea and Fudingdabaicha autumn tea got the highest total score. All in all, the spring tea of Longjing No. 43, Cuifeng, Fudingdabaicha and Soubeizhong were suitable for the production of ultramicro green tea powder, while the autumn tea of Yingshuang and Fudingdabaicha could be used to produce ultramicro green tea powder for drinking.

Key words: tea cultivar, plucking season, ultramicro green tea powder, sensory evaluation
