Document Type and Number:
WIPO Patent Application WO/2018/110585
Kind Code:
A1
Abstract:
Provided is a method for producing a fragrance composition from roasted coffee beans, the method comprising: a step which includes a step for grinding roasted coffee beans to obtain a coarse roasted coffee bean material including fines and flakes, and in which the fines and flakes are removed from a gas that contains the fines and flakes as well as an aroma compound that is produced when the roasted coffee beans are ground; an adsorption step in which the gas from which the fines and flakes have been removed is passed through an adsorbent to cause the aroma compound to be adsorbed to the adsorbent; and a collection step in which the aroma compound is collected from the adsorbent to prepare a fragrance composition containing the aroma compound, the adsorbent being accommodated in an adsorbent accommodation section in an aroma compound adsorption device, and the adsorbent accommodation section having a mesh lid at both ends in the direction of passage of the gas. This method for producing a fragrance composition from roasted coffee beans can be implemented with a common grinding device, without burdens such as major capital investment or burdens on devices, and makes it possible to experience the aroma produced when roasted coffee beans are ground.
