Enzyme extraction process for tea

机译:茶酶提取工艺

摘要

An improved process for the preparation of acid stable instant tea. Enzymatic extraction of black tea leaf using an enzyme cocktail adjusted to a critical pH is employed. Black tea is extracted with water containing tannase and one or more cell wall digesting enzymes, such as cellulase, pectinase, hemicellulase or VISCOZYME at a selected pH. 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.
