Moisture and oxygen stable composition and a process for obtaining said composition

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 40–120° C., preferably 60–100° C., to obtain a stable core product coated with the active compound encapsulated in a carbohydrate matrix.
