Abstract
A method for producing an aroma composition from roasted coffee beans, including grinding roasted coffee beans to give a crude ground powder of roasted coffee beans that contains a fine powder and thin flakes, removing the fine powder and thin flakes from a gas that contains aroma compounds emitted from the roasted coffee beans in grinding the roasted coffee beans and the fine powder and thin flakes, introducing the gas from which the fine powder and thin flakes have been removed into an adsorbent to thereby make the aroma compounds adsorbed by the adsorbent, and collecting the aroma compounds from the adsorbent to prepare an aroma composition containing the aroma compounds. The adsorbent is held in an adsorbent holder in an aroma compound adsorbing device, and the adsorbent holder has a mesh lid at both ends thereof in the gas flowing direction therethrough.
