ABSTRACT:
Coffee aromas are transferred to an oil by introducing a condensation product of a frost of carbon dioxide charged with coffee aromas and water into a heat-regulated enclosure having a lower portion for containing an oil bath and an upper portion for containing a layer of the frost introduced therein and for venting sublimed carbon dioxide. To carry out the process, the oil bath is regulated at a temperature above the freezing point of the oil, and the temperature in the enclosure above the oil bath is regulated so that during introduction of the frost into the enclosure, a layer of frost is formed and maintained above the bath, carbon dioxide of the frost is sublimated and water of the frost is melted. Sublimated carbon dioxide is vented from the enclosure, an aroma- and water-laden oil bath is removed from the enclosure and oil is added to the bath to replace oil removed from the enclosure, while introducing frost into the enclosure and regulating the temperatures. The bath removed is separated into aroma-laden oil and aroma-laden water components, and the aroma-laden water component may be contacted with an oil to obtain an aromatic oil.
