Abstract
Carbohydrate-based glassy matrices which are stable in the glassy state at ambient temperatures may be prepared by the use of aqueous plasticizers with melt extrusion. Such glassy matrices are useful for the encapsulation of encapsulates, in particular, flavoring agents.
Claims13
An encapsulation composition, comprising:
- (A) an encapsulate encapsulated in:
- (B) a glassy matrix consisting essentially of:
- (a) 60 to 90 wt. % of a modified starch;
- (b) 10 to 40 wt. % of a mono- or disaccharide;
- (c) 0 to 2.5 wt. % of a food emulsifier;
- and
- (d) a plasticizer,
- wherein said composition is prepared by a process comprising:
- (i) mixing 60 to 90 wt. % of a modified starch, 10 to 40 wt. % of a mono- or disaccharide, and 0 to 2.5 wt. % of a food emulsifier, with a liquid plasticizer and an encapsulate in an extruder to obtain a melted matrix;
- and
- (ii) extruding said melted matrix.
