Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
114 words
A process for preparing soluble coffee powder of improved stability on storage comprising: a. removing a portion of the aromatics from an aqueous coffee extract by subjecting said extract to evaporation for a time sufficient to remove from about 2 to about 20% by weight of said extract; b. drying the remaining extract from (a); c. condensing and collecting said removed aromatic portion; d. mixing said collected aromatic portion in solution with a water-soluble carbohydrate fixative selected from the group consisting of dextrins, corn syrup solids, dextrose, lactose and gums and drying the resulting solution; and e. mixing the dried product of (b) with at least a portion of the dried product of (d).
Claim 2
Dependent Claim
