ABSTRACT:
A process for recovering volatile aroma components from aroma-bearing vegetable materials such as roast and ground coffee. A carrier gas is passed through the vegetable material to strip aromas therefrom, and the resulting aroma-laden gas is contacted with a cryogenic liquid such as liquid nitrogen to condense the aromas from the gas. The carrier gas has a boiling point equal to or lower than that of the cryogenic liquid. Because the efficacy of the condensation step is substantially independent of the gas flow rate, the optimum gas flow rate for effective stripping may be used without loss of aromas at the condensation step.
