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.
