Abstract
A process is described for the production of a packaged green tea beverage containing non-polymer catechins at a concentration of 0.05 to 0.5 wt. %. According to the process, an aluminosilicate which has an iron release rate of not greater than 0.8 mg/kg to a catechin-containing solution is brought into contact with a green tea mixture of a green tea extract and a concentrate of green tea extract.
