Title:
METHOD FOR PRODUCING POLYPHENOLS
Document Type and Number:
WIPO Patent Application WO/2017/169652
Kind Code:
A1
Abstract:
The method for producing polyphenols according to one embodiment of the present invention comprises a step for mixing used tea leaves with water to generate a liquid mixture. The liquid mixture is heated. From the heated liquid mixture, at 70°C or higher, a solid residue of tea leaves and an extraction liquid are separated. According to this configuration, the efficiency of polyphenol extraction can be enhanced by the step for separating the solid residue of tea leaves and the extraction liquid from the heated liquid mixture at 70°C or higher. Thus, the present invention makes it possible to extract sufficient amounts of polyphenols even when using used tea leaves that remain after tea extract has been extracted from tea leaves.
