Abstract
Green and Oolong tea leaves are oxidized to alter the organoleptic and aesthetic characteristics of aqueous extracts obtained therefrom and to provide extracts which have minimal turbidity, particularly when cooled. The oxidation reaction is performed on leaves which contain moisture only in an amount such that the oxidation reaction occurs at localized sites on and within the tea leaf structure.
