Abstract

The present invention relates to a method of producing an aromatized food or beverage product, wherein an aroma fraction is obtained from a plant extract, said aroma fraction is being contacted with an oil to remove undesired aroma compounds, and the aroma fraction from which undesired compounds have been removed are combined with a food or beverage composition to produce an aromatized food or beverage product.

First claim

The invention claimed is:

1. A method of producing an aromatised food or beverage product, the method comprising:
a) collecting an aroma fraction from a plant material selected from the group consisting of (i) roast and ground coffee and (ii) a coffee extract, in the form of a gas comprising water vapor;
b) contacting the aroma fraction with an oil to remove at least one undesired aroma compound selected from the group consisting of furans, pyrroles, thiols, and mixtures thereof from the aroma fraction;
c) separating the oil from the aroma fraction;
d) condensing the aroma fraction to produce an aqueous aroma containing liquid; and
e) combining the aqueous aroma containing liquid from which the at least one undesired aroma compound selected from the group consisting of furans, pyrroles, thiols, and mixtures thereof have been removed, with a food or beverage composition to form the aromatised food or beverage product.

2. The method of claim 1 further comprising drying the aromatised food or beverage product to produce a dried aromatized food or beverage product.

3. The method of claim 1 , wherein the aroma fraction in the form of a gas is collected by stripping aroma from the plant material with steam.

4. The method of claim 1 , wherein the at least one undesired aroma compound removed from the aroma fraction by the contacting of the aroma fraction with the oil comprises furans, pyrroles, and thiols.

5. The method of claim 1 , wherein step b) and step c) are performed in a gas-liquid absorption column.

6. The method of claim 1 , wherein the plant material comprises coffee extract.

7. The method of claim 6 wherein the plant material is roast and ground coffee beans.

8. The method of claim 7 , wherein the food or beverage composition comprises a coffee extract, and the aromatised food or beverage product is an aromatized coffee extract.

9. The method of claim 8 , wherein the aroma fraction is collected from roast and ground coffee beans comprising at least 5% by weight of robusta coffee beans.

10. The method of claim 8 , wherein the coffee extract in step d) has been concentrated to a solids content of at least 10% before being combined with the aqueous aroma containing liquid from which the at least one undesired aroma compound selected from the group consisting of furans, pyrroles, thiols, and mixtures thereof has been removed.

11. The method of claim 8 , wherein the coffee extract in step e) has been produced from roasted coffee beans comprising at least 5% by weight of robusta coffee beans.

12. The method of claim 1 , wherein the food or beverage composition comprises a creamer composition, and the aromatised food or beverage product is an aromatized creamer composition.

13. The method of claim 1 , wherein step d) is performed by cooling and/or compression of the aroma fraction to produce the aqueous aroma containing liquid.

14. The method of claim 1 , wherein gas from the aroma fraction remaining after step d) is subjected to one or more further condensation steps to produce one or more further aroma fractions.

15. The method of claim 14 wherein at least one of the one or more further aroma fractions is combined with the aqueous aroma containing liquid, from which the at least one undesired aroma compound selected from the group consisting of furans, pyrroles, thiols, and mixtures thereof has been removed, and the food or beverage composition in step e).

16. The method of claim 1 , wherein in step e) the aqueous aroma containing liquid, from which the at least one undesired aroma compound selected from the group consisting of furans, pyrroles, thiols, and mixtures thereof has been removed, is oil-free when combined with the food or beverage composition.

17. The method of claim 1 , wherein the oil in step b) is MCT oil or coffee oil.

18. The method of claim 1 , wherein the aqueous aroma containing liquid, from which the at least one undesired aroma compound selected from the group consisting of furans, pyrroles, thiols, and mixtures thereof has been removed, and the food or beverage composition in step e) are further combined with a second aroma containing liquid produced by a method comprising:
i) collecting an aroma fraction from a plant material in the form of a gas comprising water vapor; and
ii) condensing the aroma fraction to produce an aqueous aroma containing liquid.

19. A method of producing an aromatised food or beverage product, the method comprising:
a) collecting an aroma fraction from a plant material selected from the group consisting of roast and ground coffee and a coffee extract, in the form of a gas comprising water vapor;
b) condensing the aroma fraction to produce an aqueous aroma containing liquid;
c) contacting the aqueous aroma containing liquid with an oil to remove at least one undesired aroma compound selected from the group consisting of furans, pyrroles, thiols, and mixtures thereof from the aroma fraction;
d) separating the oil from the aqueous aroma containing liquid; and
e) combining the aqueous aroma containing liquid from which the at least one undesired aroma compound selected from the group consisting of furans, pyrroles, thiols, and mixtures thereof has been removed, with a food or beverage composition to form the aromatised food or beverage product.

20. The method of claim 19 , wherein a porous hydrophobic membrane is used to contact the aqueous aroma containing liquid and the oil in step b) and for the separating of the oil from the aroma fraction in step c).
