After adding a large quantity of water to raw tea leaves that have not undergone wilt treatment, the tea leaves are crushed in a blender and then let stand, shaken, or agitated, thereby efficiently convening four types of catechins in the raw tea leaves to theaflavins. After adding water and crushing the raw tea leaves, letting the tea leaves stand allows theaflavins to be selectively obtained with high yield. Shaking the raw tea leaves which have had water added and been crushed allows four types of theaflavins to be obtained with high yield. The generated theaflavins can be easily collected using a method such as extraction by organic solvent. | 03-10-2011 |
