A coffee aroma such as a coffee aroma frost is contacted with a volatile organic carrier liquid at a processing temperature at which the carrier is in the liquid state and at which any moisture present is in the form of ice, to effect fixation of the aroma into the carrier liquid. The carrier liquid has a freezing point below the processing temperature, a boiling point above the processing temperature, a vapor pressure of at least 0.01 mm Hg at 25 C and atmospheric pressure, and a water solubility of not more than 10 % by weight. |
