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.
Claims67
A composition, comprising:
- (A) an encapsulate encapsulated in:
- (B) a glassy matrix comprising
- (a) 25 to 80 wt. % of a maltodextrin having 5 to 15 D.E.;
- (b) 2 to 45 wt. % of a food polymer;
- and
- (c) 10 to 30 wt. % of a mono- or disaccharide or corn syrup solids having 24 to 42 D.E.,
- wherein said food polymer is selected from the group consisting of methyl cellulose, hydroxypropyl methyl cellulose, high methoxypectin, gum arabic, locust bean gum, guar gum, gum ghatti, gum tragacanth, gum karaya, xanthan, pregelatinized starches, and gelatin.
