Claims(US2009035440AA): [EN] 1. A composition comprising: polyphenol; and polymer comprising amine groups, wherein the polymer is not casein; wherein at least 0.1 percent polyphenol by weight of the composition is present as part of a complex with the polymer, and wherein the complex is in the form of particles. 2. A composition according to claim 1 wherein at least 90 percent by weight of the particles have a particle size of less than 5000 nm. 3. A composition according to claim 1 wherein the particles are dispersed in a supporting medium. 4. A composition according to claim 1 wherein the polyphenol is selected from flavones, flavonols, flavanones, 3-hydroxyflavanones, isoflavones, neoflavonoids, flavan-3-ols, anthocyanidins, resveratrol or a mixture thereof. 5. A composition according to claim 4 wherein the polyphenol is selected from catechins, theaflavins or a mixture thereof. 6. A composition according to claim 1 wherein the weight-average molecular weight of the polymer is at least 1 kDa. 7. A composition according to claim 1 wherein the polymer is at least one of: protein containing amino acids containing amine groups, a polypeptide containing amino acids containing amine groups, or a mixture thereof; DNA, RNA or a mixture thereof; poly(vinylpyridine), poly(vinylpirrolidone), polyaniline, polypyrrole, or a mixture thereof, and polysaccharide containing amine groups. 8. A composition according to claim 7 wherein the protein is selected from gliadin, zein, collagen, gelatine, elastin, saliva proteins, whey proteins, soy proteins, their hydrosylates, their derivatives, or a mixture thereof. 9. A composition according to claim 8 wherein the protein is whey protein. 10. A composition according to claim 1 which is a food composition. 11. A composition according to claim 10 wherein the composition is a beverage, preferably a tea-based beverage. 12. A composition according to claim 10 wherein the composition is chocolate. 13. A composition according to claim 12 wherein the composition is white chocolate. 14. A composition according to claim 1 wherein the composition comprises theobromine. 15. A unit dose of a composition according to claim 1 comprising at least 50 mg total polyphenol. 16. A unit dose according to claim 15 having a mass of less than 500 g. 17. Use of a polymer comprising amine groups for reducing or eliminating bitterness and/or astringency of polyphenol, wherein the polymer is not casein. 18. Use according to claim 17 wherein at least some of the polyphenol is present as a complex with the polymer. 19. Use according to claim 18 wherein the complex is in the form of particles. 20. A method of manufacturing a composition according to claim 1 wherein the complex is formed by contacting the polymer and polyphenol in the supporting medium. 21. A method of manufacturing a composition comprising a complex of polyphenol and polymer comprising amine groups, the process comprising the steps of: i) mixing the polyphenol and polymer thereby to form a complex; ii) recovering the complex; and then iii) combining the complex with a supporting medium. 22. A method according to claim 21 wherein the complex is recovered in step (ii) as particles and wherein step (iii) comprises dispersing the particles in the supporting medium. 23. A method according to claim 21 wherein the polymer is not casein.M1 - A23F3/00;A23F3/16;A23F3/20;A23F5/00;A23F5/16;A23G1/00;A23G1/30;A23G3/34;A23G3/44;A23J1/00;A23L1/30;A23L1/305;A23L2/38;A23L2/42;A23L2/48;A23L2/52;A23L3/3463;A23L3/3526;A61K45/00;A61K8/72;C08B37/00;C08F26/00;C08G73/00;C08G73/02;C08K5/13;C08L101/02;C08L89/00;
