A preparation process of a purified green tea extract including mixing a green tea extract treated with an enzyme having a tannase activity in a mixed solution containing an organic solvent and water at a mass ratio exceeding 90/10 and not greater than 97/3, and separating a precipitate thus formed.
The process is for producing a purified green tea extract, from a green tea extract, containing non-polymer catechins in high concentration, which can improve the taste by reducing bitterness/astringency and miscellaneous tastes caused by dietary fibers of green tea, provide a reduced protein content, and make it easy to drink.
