Abstract
The present invention is a method of entrapping an additive within carbohydrate bodies. The additive is drawn into the internal structure as a fluid during transformation of the bodies from a substantially amorphous state to a crystalline state. The present invention is also a delivery system including a carbohydrate body having an internal free volume space defined by an at least partially crystalline structure at equilibrium conditions, and an additive loaded within the carbohydrate body.
