Abstract:

Green tea materials were milled using a high-density variable frequency speed miller at various rotational speeds ranging from 40 to 80 r/min in order to study the effect of high-density stone milling on the physico-chemical properties and sensory quality of green tea. The results showed that powdered green tea obtained at 60 r/min had a bright light green color, a pure aroma and a neutral taste, was uniform in particle size and scored the highest overall sensory score.

Key words: tea, stone miller, milling, powder, sensory evaluation
