FIELD: food industry.
SUBSTANCE: tea product is suggested which is soluble in cold water and its production method. Method includes extraction of the material with water to produce tea extract and removal of tea leaves from the tea extract. The tea extract without tea leaves is then concentrated, the extract is cooled, tea cream is removed from the tea extract to produce tea cream fraction and decreamed tea fraction. After that the tea cream fraction is dissolved in water at 40-100°C foolwed by ultrafiltration causing formation of permeate and retentate and extraction of permeate.
EFFECT: tea product obtained is soluble in cold water, has good colour characteristics and the method suggested does not depend on adding any chemicals and provides acceptable yield of the product.
