PROCESS FOR DECAFFEINATING TEA AND RESULTING TEA PRODUCT ABSTRACT OF THE DISCLOSURE An aqueous extract of tea, containing native tea tannins and caffeine, is cooled to provide an aqueous solubles phase containing cold-water soluble components of the extract, including a minor portion of the caffeine, and an insolubles phase containing tea tannins complexed with a major portion of the caffeine. The aqueous solubles phase is separated from the insolubles phase, and the latter is subjected to decaffeination to provide decaffeinated tannins which may then be recombined with the aqueous solubles phase. The resulting treated extract from which the major portion of the caffeine has been removed can be dried or, if desired, subjected to further decaffeination and thereafter dried to provide a cold-water-soluble decaffein- ated tea. Further features of the invention are set forth in the following description.
