Abstract

The aqueous extract having a high content of soluble materials is placed in contact with a water-immiscible liquid fat at a temperature of at least 65 DEG C for a period sufficient to transfer the caffeine from the aqueous extract towards the fat, and then the fat charged with caffeine is separated from the aqueous extract. After possible reincorporation of the volatile aromatic materials which were separated off before decaffeination, it is possible to dry the extract by spraying or by freeze-drying in order to obtain an instantly-dissolving powdered coffee or tea.
