Abstract
A method and a system for recovering aroma compounds from a coffee extract is provided. The coffee extract and a steam flow is provided to a two-fluid nozzle, to generate a spray of coffee extract in steam, which spray is separated to provide an aroma rich gas and stripped coffee extract.
Claims20
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.

A system for recovering aroma compounds from a coffee extract, the system comprising:
- a gas-liquid separator having a liquid outlet and a gas outlet;
- and
- a two-fluid nozzle configured for generating a spray into the gas-liquid separator;
- wherein the two-fluid nozzle comprises a first channel and a second channel, the first and second channel being in fluid communication at a mixing zone of the two-fluid nozzle, and the first channel is connected to a supply of coffee extract and the second channel is connected to a supply of steam.

A method for producing a soluble coffee product from coffee beans, the method comprising:
- providing a coffee extract;
- 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;
- obtaining the aroma rich gas as recovered aroma or further processing the aroma rich gas;
- concentrating the stripped coffee extract by evaporation of water, thereby providing a concentrated coffee extract;
- adding the recovered aroma to the concentrated coffee extract;
- and
- spray drying or freeze drying the concentrated coffee extract to obtain the soluble coffee product.
