Abstract

Disclosed is a novel instant coffee comprising aromatized soluble particles and a method of aromatizing soluble coffee particles. The soluble coffee particles are mixed with roast whole beans, and the mixture is held for at least two days. The result is aromatized soluble coffee particles, as evidenced by the presence of relatively high amounts of 2-methylpyrazine in instant coffee comprising said particles. The instant coffee has a favorable content in aroma components, yet with a low oil content.

First claim

The invention claimed is:

1. A process for the preparation of aromatized soluble coffee particles, the process comprising
providing soluble coffee particles,
mixing the soluble coffee particles with roast whole coffee beans,
holding the mixture for at least two days, and
separating the beans from the soluble coffee particles.

2. A process according to claim 1 , wherein the soluble coffee particles are provided by
making a liquid coffee extract, and
drying the coffee extract so as obtain soluble coffee particles.

3. A process according to claim 2 , wherein the drying is freeze-drying.

4. A process according to claim 1 , wherein the weight ratio of coffee beans to soluble coffee particles is 5:1.

5. A process according to claim 1 , wherein the weight ratio of coffee beans to soluble coffee particles is 3:1 to 1:3.

6. A process according to claim 1 , wherein the holding time is three days to two weeks.

7. A process according to claim 1 , wherein coffee aroma comprising 2-methylpyrazine is transferred to the soluble coffee particles.

8. A process according to claim 1 , wherein the roast whole coffee beans are of a dark roast.

9. The process according to claim 2 , wherein the soluble coffee particles are provided by
making a liquid coffee extract and
drying the coffee extract after concentrating the extract so as to obtain soluble coffee particles.

10. A process according to claim 1 , wherein the weight ratio of coffee beans to soluble coffee particles ranges from 4:1 to 1:4.

11. A process according to claim 1 , wherein the weight ratio of coffee beans to soluble coffee particles ranges from 2:1 to 1:2.

12. A process according to claim 1 , wherein the holding time is four to ten days.
