Abstract
Tea extract is stabilized for use in vending machines and for storage and transport in frozen or chilled condition by the incorporation therein of a carragheenan.
Claims5
Process for stabilization of tea extract for preventing sedimentation of "creaming" substances on chilling and/or during storage at cold temperatures, the extract being stabilized without substantial viscosity increase so that it is capable of being used in automatic dispensing machines without impairing the accuracy of dosing, the process avoiding removal of creaming substances, or changing the natural pH of the extract, the process consisting essentially of:
- a. extracting a tea extract from tea with hot water;
- and
- b. mixing the tea extract at a temperature of at least about 60.degree. C for at least about 11/2 minutes with an effective stabilizing amount of carragheenan for preventing creaming on cooling of either the extract or a diluted tea drink made therefrom and also effective to provide an extract that is stable without substantial increase in viscosity.
