Abstract
A green tea composition comprising 100 parts by weight of green tea leaf, and 0.01 to 30 parts by weight of trehalose; a process for producing a green tea composition, comprising the steps of heat-treating fresh tea leaf, drying the heat-treated leaf, and crushing the dried leaf, wherein the fresh leaf is brought into contact with trehalose before or after or simultaneously with the heat treatment of the fresh leaf; a molding matter of a green tea composition, obtained by molding a green tea composition comprising 35 to 80% by weight of granulated or powdered green tea (component (A)), 10 to 60% by weight of maltose (component (B)), and 1 to 20% by weight of trehalose (component (C)); and a process for producing a molding matter of a green tea composition, comprising the step of molding the above green tea composition. The green tea composition and the molding matter thereof undergo neither oxidation nor discoloration, so that they can preserve their green colors for a long period of time. In addition, they contain catechins at concentrations high enough to show the pharmacological effects of catechins.
