ABSTRACT:
This invention is designed to obtain desirable flavor and aroma volatiles during processing of an aqueous coffee extract obtained from roasted and ground coffee. The overall process of preparing soluble coffee by spray drying a concentrated aqueous extract is improved by employing a stripper to remove up to 20% of the extract prior to concentration and to recover non-condensible and condensible aromas in cold water using an absorber having 4-48 plates and a 0.1/1 to 30/1 L/V ratio prior to reintroducing the absorbed aromas into the concentrated coffee extract and spray drying it to give an aromatized dry soluble coffee.
