초록

A stable water-soluble Desorbate instant tea having a flavor, aroma, appearance and chemical composition 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 a...
