Method for making a cold water soluble tea extract

摘要

A method for making a cold water soluble black tea extract. The method involves extracting tea solids from black tea leaves using an extraction liquid to provide a whole tea extract, oxidizing the whole tea extract under superatmospheric pressure and at a temperature above 60° C. to provide a cold water soluble liquor, cooling the cold water soluble liquor to precipitate any residual cold water insoluble material, and separating the residual cold water insoluble material from the cold water soluble liquor to give the cold water soluble black tea extract. A method for making a cold water soluble black tea powder is also described.
