The invention claimed is: 1. A flavor or fragrance containing a cyclodextrin particle comprising said cyclodextrin particle and a flavor or fragrance, wherein said cyclodextrin particle has 0.04% or less surface oil, wherein said cyclodextrin particle has a particle size in a range of 50 to 1000
The invention claimed is: 1. A flavor or fragrance containing a cyclodextrin particle comprising said cyclodextrin particle and a flavor or fragrance, wherein said cyclodextrin particle has 0.04% or less surface oil, wherein said cyclodextrin particle has a particle size in a range of 50 to 1000 μm, wherein said cyclodextrin particle comprises cellulose ether, wherein said cyclodextrin particle is obtained by a single stage fluidized bed process from a spray mixture, and wherein a gas introduction temperature is from 80 to 180�� C. and a gas outlet temperature is from 40 to 95�� C. 2. The flavor or fragrance containing said cyclodextrin particle according to claim 1, wherein said cellulose ether is selected from the group consisting of methylcellulose, ethylcellulose, ethylhydroxyethyl-cellulose, propyl-cellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, carboxymethylhydroxyethyl-cellulose, carboxy-methylcellulose enthalten, and mixtures thereof. 3. The flavor or fragrance containing said cyclodextrin particle according to claim 1, wherein said cellulose ether further comprises carboxymethylcellulose. 4. The flavor or fragrance containing said cyclodextrin particle according to claim 1, wherein said cyclodextrin particle has a particle size in the range from 100 to 300 μm. 5. The flavor or fragrance containing said cyclodextrin particle according to claim 1, wherein said fluidized bed process is a fluidized bed spray granulation process. 6. The flavor or fragrance containing said cyclodextrin particle according to claim 1, wherein said cyclodextrin particle is selected from the group consisting of alpha cyclodextrin, beta cyclodextrin, gamma cyclodextrin, and mixtures thereof. 7. The flavor or fragrance containing said cyclodextrin particle according to claim 6, wherein said cyclodextrin particle is beta cyclodextrin. 8. The flavor or fragrance containing said cyclodextrin particle according to claim 1, wherein an amount of said flavor or said fragrance in said cyclodextrin particle is from 0.01 to 30 wt. %. 9. A product comprising a flavor or fragrance containing said cyclodextrin particle according to claim 1, wherein said product comprises consumables, pharmaceutical products, and everyday articles. 10. A process for producing the cyclodextrin particle according to claim 1, said method comprising: spraying an aqueous spray mixture in a single stage fluidized bed device, wherein said aqueous spray mixture comprises at least one cyclodextrin, at least one flavor or fragrance, and at least one cellulose ether. 11. The process according to claim 10, wherein a fluidized bed device is a fluidized bed spray granulation apparatus. 12. The process according to claim 10, wherein said aqueous spray is sprayed continuously. 13.
