In order to analyze and compare the quality of ultra- green tea powder separately processed by the mill and grinding machine, first-grade grinding tea, Yuhang steam sheet, and drying green tea sheet as raw materials were chose, which were processed into ultra-green tea powder by ball milling and grinding. It conducted sensory evaluation, analysis on chlorophyll, particle size and the color of these samples to determine the quality of tea powder. Results showed that the ultra-green tea powder processed by ball mill machine was better than that of grinding machine in terms of particle size, color, aroma, and taste. It kept its flavor characteristics of raw materials.Therefore, the ball milling process was more suitable for processing ultra-green tea powder.
