IMPROVED LOW-TEMPERATURE STEAM DESORBATE PROCESS FOR IMPROVED INSTANT TEA Abstract A stable water-soluble Desorbate instant tea having a flavor, aroma, appearance and chemical composi- tion approximating that of fresh expertly brewed tea is made by a process comprising passing steam at reduced pressures through a columnar bed of ground tea leaves to pre-wet and pre-swell an upper portion of said leaves; and then passing water and wet steam at reduced pressures and low temperatures through said bed to desorb and extract from said tea leaves an aqueous tea extract while maintaining a weight ratio of said extract to dry tea leaves of from about 0.5:1 to about 3:1, and collecting said extract in a cold trap. Decreaming of the extract prepared by this process is not necessary to provide a water-soluble dry instant tea which, upon reconstitution in water, provides an iced beverage that tastes like an iced tea made from fresh, expertly brewed tea. The solu- bility and solution stability of the Desorbate tea of this invention are surprisingly improved by treat- ing the process water with a minor amount of a higher chain polyphosphate glass, a bisulfite, a sulfite and/or a suitable carrageenan.
