Abstract
Soluble coffee of improved stability during storage is prepared by removing a portion of the aromatics from an aqueous coffee extract, drying the remaining extract, fixing the removed aromatics by mixing them in solution with a fixative and drying the resultant solution, and adding at least a portion of the fixed aromatics to the dried remaining extract. The soluble coffee powder so prepared is characterized by its lack of off-flavors normally developed during storage.
Claims8
