Abstract

A method and device for efficiently removing an unwanted component included in a beverage, which includes bringing the beverage into contact with a metal-supported zeolite.

First claim

The invention claimed is:

1. A method for removing an unwanted component included in a beverage, comprising:
(1) bringing the beverage into contact with a metal-supported zeolite; and
(2) bringing the beverage, which has been brought into contact with the metal-supported zeolite, into contact with a metal-trapping material, wherein
[i] the unwanted component is at least one selected from the group consisting of dimethyl disulfide (DMDS) and dimethyl trisulfide (DMTS);
the unwanted component is removed in both steps (1) and (2);
the beverage is alcoholic beverages;
[ii] a metal which constitutes the metal-supported zeolite is silver;
the amount of silver is 5 to 25 mass % based on a total amount of the metal-supported zeolite;
[iii] the metal-trapping material is a zeolite having Na+ as an ion-exchangeable cation;
flavor and aroma components are substantially left in the beverage; and
[iv] the flavor and aroma components include acetaldehyde; and
contact with the metal-supported zeolite and the metal-trapping material does not reduce the concentration of acetaldehyde.

2. The method according to claim 1 , wherein a zeolite which constitutes the metal-supported zeolite is a Y zeolite or a β zeolite.

3. The method according to claim 1 , wherein the zeolite as the metal-trapping material traps metal eluted from the metal-supported zeolite and removes the unwanted component included in the beverage.

4. The method according to claim 1 , wherein the flavor and aroma components further include at least one compound selected from the group consisting of:
ethyl lactate, furfural, β-phenethyl alcohol, i-amyl acetate, ethyl caproate, ethyl caprylate, β-phenethyl acetate, ethyl caprate, ethyl laurate, ethyl myristate, ethyl palmitoleate and ethyl linoleate.

5. The method according to claim 1 , wherein the alcoholic beverages are distilled alcoholic beverages.

6. The method according to claim 1 , wherein the alcoholic beverages is whisky.

7. The method according to claim 1 , wherein the zeolite as metal trapping material is Y-type zeolite having Na + as an ion exchangeable cation.

8. The method according to claim 1 , wherein the amount of the zeolite having Na + as an ion-exchangeable cation in step (2) is 0.3 to 3.0 in a volume ratio based on the metal-supported zeolite.

9. The method according to claim 1 , wherein the silver is eluted in the alcoholic beverage in step (1) and removed in step (2).

10. The method according to claim 1 , wherein the silver concentration after step (1) is 2.9 to 13 ppm.

11. The method according to claim 1 , wherein the silver concentration after step (2) is less than 0.01 ppm.
