This invention relates to an improved process for the separation and isolation of coffee aroma constituents from roasted coffee, combining the aroma constituents with an edible substance and subsequently incorporating the aromatized substance in a food product. The process involves improving the condensation of vapors generated from the distillation of coffee oil by condensing the distilled aroma constituents onto a sleeve cooled by and snugly surrounding a container filled with coolant. The sleeve is removed and the aroma constituents condensed thereon are then preferably combined with an edible substance by manipulating the condensed constituents quickly and efficiently thus minimizing aroma loss and degradation caused by undesirable prolonged contact with air.

A condenser which comprises: a heat-conductive sleeve removably and snugly surrounding a heat-conductive container, the container having a coolant therein, and a condensing chamber enclosing said heat-conductive sleeve, said condensing chamber having ports for the passage of a gas stream within the space between the sleeve and the condensing chamber, and said condensing chamber having a removable cover which seals an opening through which the sleeve is passed when removed from the container. An apparatus for the separation and recovery of gas stream constituents comprising: a distillation chamber wherein a coffee oil is subject to distillation at sub-atmospheric pressures and mild temperatures to obtain a gas stream of aroma constituents therefrom; and the condenser of claim 1, the aroma constituents being condensed onto the outer surface of the heat-conductive sleeve of the condenser.
