The invention relates to a moisture and oxygen stable composition comprising inert core particles and a partial or complete coating thereon of at least one active compound encapsulated in a carbohydrate matrix, which matrix is characterized by: 5 to 95 wt. % high molecular weight film forming carbohydratre; 5 to 30 wt. % mono, di and trisaccharides; and 0 to 30 wt. % maltodextrin, based on the total weight of the carbohydrate matrix. The active compound to be encapsulated in the carbohydrate matrix can be selected from the group consisting of flavorants, fragrances, pharmaceuticals and wash-active components.

The invention claimed is: 1. A moisture and oxygen stable composition comprising inert core particles partially or completely coated with at least one active compound encapsulated in carbohydrate matrix, which matrix is characterized by 45 to 70 wt. % high molecular weight film forming carbohydrate
The invention claimed is: 1. A moisture and oxygen stable composition comprising inert core particles partially or completely coated with at least one active compound encapsulated in carbohydrate matrix, which matrix is characterized by 45 to 70 wt. % high molecular weight film forming carbohydrate; 5 to 30 wt. % mono, di and trisaccharides; and 10 to 30 wt. % maltodextrin based on the total weight of the carbohydrate matrix. 2. The composition according to claim 1, characterized in that the film forming carbohydrate is present in an amount of 50-60 wt. % based on the total weight of the carbohydrate matrix. 3. The composition according to claim 1, characterised in that the film forming carbohydrate is selected from the group consisting of gum arabic, gum acacia, lipophilically modified searches and mixtures thereof. 4. The composition according to claim 1 or 3, characterised in that the mono, di and trisaccharides are present in an amount of 15-25 wt. % based on the total weight of the carbohydrate matrix. 5. The composition according to claim 1, characterised in that at least 50 wt. % of the mono, di and trisaccharide material is a disaccharide. 6. The composition according to claim 5, characterised in that the disaccharide is sucrose. 7. The composition according to claim 1, characterised in that the maltodextrin has a dextrose equivalent (DE) in the range of 1 to 25. 8. The composition according to claim 1, characterised in that the active component encapsulated in the carbohydrate matrix is selected from the group consisting of flavourants, fragrances, pharmaceuticals and wash-active components. 9. The composition according to claim 1, characterised in that the encapsulated active compound is at least one flavourant selected from the group consisting of essential oils, like bergamot oil, citrus oil, bakery flavourants and savoury flavourants. 10. The composition according to claim 1, characterised in that the encapsulated active compound is present in an amount of 1-40 wt. % based on the total weight of the active compound containing carbohydrate matrix. 11. The composition according to claim 1, characterised in that the core particles are selected from the group consisting of tea fannings, tea dust, tobacco particles, sugar crystals, salt crystals, plant seeds, fibres, spray-dried particles and cellulose cells. 12. The composition according to claim 1, characterised in that the core particles have a size in the range of 0.1-3 mm. 13. The composition according to claim 1, characterised in that the weigh ratio of the core particles and the coating is from 5:1 to 1:5. 14. A process for producing a moisture and oxygen stable composition comprising the steps of (a) forming an aqueous carbohydrate solution containing a carbohydrate mixture consisting of 45 to 70 wt. % high molecular weight film forming carbohydrate(s), 5 to 30 wt. % mono, di and trisaccharide(s), and 10 to 30 wt. % maltodextrin(s), wherein the wt. % is based on the total weight of the carbohydrate matrix; (b) incorporating at least one active compound into the solution of step (a); and (c) introducing the aqueous solution of step (b) into a fluid bed comprising inert core particles and using an inlet air temperature of 40-120째 C., preferably 60-100째 C., to obtain a stable core product coated with the active compound encapsulated in a carbohydrate matrix. 15. The process according to claim 14, characterised in that the active compound is selected from the group consisting of flavourants, fragrances, pharmaceuticals and wash-active components. 16. The process according to claim 14 or 15, characterized in that the core particles are selected from the group consisting of tea fannings, tobacco particles, sugar crystals, salt crystals plant seeds, fibres, spray-dried particles and cellulose cells. 17. Products comprising the composition prepared by the process according to claim 5. 18. The composition according to claim 1, wherein the maltodextrin has a dextrose equivalent (DE) in the range of 10 to 20. 19. The composition according to claim 1, characterized in that the composition is oxygen and moisture stable for a period of time corresponding to an ambient shelf life of about 1 year at 20% and relative humidity of 30%.
