Abstract
A process for the preparation of acid stable instant tea. Enzymatic extraction of black tea leaf with water containing tannase and one or more cell wall digesting enzymes, such as cellulase, pectinase, hemicellulase or VISCOZYME is employed. The resulting tea extract can then be pasteurized, polished, and made into a finished beverage or concentrated and dried in the usual manner. As a result, natural tea products are obtained which have improved acid stability, good color and good clarity.
