1. A method for recovery of aroma compounds from a coffee extract, the method comprising:
providing the coffee extract to a two-fluid nozzle;
providing a steam flow to the two-fluid nozzle;
contacting the coffee extract and the steam flow in a mixing zone of the two-fluid nozzle, thereby atomizing the coffee extract to provide a spray;
separating the spray, thereby providing a stripped coffee extract and an aroma rich gas; and
obtaining the aroma rich gas as recovered aroma or further processing the aroma rich gas.
