Abstract
Aromas, carbon dioxide and water obtained from roasted coffee are condensed into a frost. An oil is mixed with the frost and subjected to sublimate the carbon dioxide from the oil and frost mixture, and then the mixture is melted to obtain an oil phase and an aqueous phase. The oil phase is separated from the aqueous phase, and the aqueous phase is contacted with an oil to transfer aromas to the oil which then is incorporated into a soluble coffee powder.
