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.

Divulgation d'une matière à mouler à base d'une composition de thé vert, obtenue par moulage d'une composition de thé vert comprenant de 35 à 80 % en poids de thé vert granulaire ou en poudre (composant A), de 10 à 60 % en poids de maltose (composant B) et de 1 à 20 % en poids de tréhalose (composant C)), et d'un procédé pour produire une matière moulée à base d'une composition de thé vert comprenant l'étape de moulage de la composition de thé vert susmentionnée. Cette composition de thé vert et la matière à mouler à base de celle-ci ne subissent ni oxydation ni discoloration. Elles peuvent donc conserver leur couleur verte pendant une longue période. De plus, elles contiennent des catéchines à des concentrations assez élevées pour exhiber les effets pharmacologiques de celles-ci.
