A cold water soluble tea product and its process is provided. The process comprises the steps of extracting tea material with water to give a tea extract, deleafing the tea extract, concentrating the deleafed tea extract, cooling the extract, decreaming the concentrated tea extract to provide a cream fraction and a decreamed fraction, solubilising the cream fraction in water at a temperature of from 40 to 100° C. and then subjecting the solubilised cream fraction to an ultrafiltration step so as to produce a permeate and a retentate and recovering the permeate. |
