N1 - Claims(WO14001050A1): [EN] CLAIMS 1. A composition in the form of a particle comprising a hydrophobic polymer, wherein the polymer comprises one or more prolamins, selected from the group consisting of zein, gliadin, hordein, secalin, and avenin; and one or more compounds selected from the group of the curcuminoids; and a water-soluble blue colourant; and wherein the particles have a volume weighted mean diameter of between 10 and 1000 nanometer. 2. A composition according to claim 1, wherein the hydrophobic polymer comprises zein. 3. A composition according to claim 1 or 2, wherein the curcuminoid comprises curcumin. 4. A composition according to any of claims 1 to 3, wherein the water-soluble colourant comprises indigocarmine. 5. A composition according to any of claims 1 to 4, wherein the particles have a volume weighted mean diameter ranging from 20 to 800 nanometer, preferably from 80 to 300 nanometer. 6. A composition according to any of claims 1 to 5, wherein the particles comprise one or more compounds selected from the group of the curcuminoids at a concentration ranging from 0.5 to 25 percent by weight of the composition, preferably ranging from 1 to 20 percent by weight. 7. A composition according to any of claims 1 to 6, wherein the particles comprise a water-soluble blue colourant at a concentration ranging from 0.5 to 25 percent by weight of the composition, preferably ranging from 1 to 20 percent by weight. 8. A food product comprising a composition according to any of claims 1 to 7. 9. A method for preparation of a composition according to any of claims 1 to 7, comprising the steps: a) dissolving a hydrophobic polymer, wherein the polymer comprises one or more prolamins, selected from the group consisting of zein, gliadin, hordein, secalin, and avenin; and one or more compounds selected from the group of the curcuminoids; and a water-soluble blue colourant; in a mixture of water and organic solvent, wherein the solvent is miscible with water; and at a pH of maximally 7; preferably maximally 5; preferably ranging from 2 to 4; b) adding the mixture from step a) to water under stirring; c) optionally separating particles precipitated in step b) from the remaining liquid; d) optionally drying the particles to remove water and solvent. 10. A method according to claim 9, wherein the mixture of water and organic solvent comprises ethanol, preferably at a volumetric ratio of ethanol to water ranging from 60:40 (v/v) to 90:10 (v/v). 1 1. 11.A method according to claim 9 or 10, wherein the temperature in step a) ranges from 0 to 60 <sup><</sup>€, preferably 10 to 60<sup><</sup>€. 12. A method according to any of claims 9 to 1 1, wherein in step a) the hydrophobic polymer comprises zein. 13. A method according to any of claims 9 to 12, wherein in step a) the curcuminoid comprises curcumin. 14. A method according to any of claims 9 to 13, wherein in step a) the water-soluble colourant comprises indigocarmine. 15. Use of a composition according to any of claims 1 to 7 or prepared according to any of claims 9 to 14 as a green colourant for aqueous products, preferably aqueous food products.
