ABSTRACT:
A process for producing a tea extract which forms little or no haze when stored at refrigeration temperatures. The process comprises incubating a mixture of oxidase, tannase and tea extract, and then separating insoluble solids from the tea extract. The tea extract is preferably a concentrate which is subsequently diluted to provide a ready-to-drink beverage. Haze which develops on cold storage of the extract or of tea beverages prepared from the extract is significantly reduced.
