Encapsulation matrix
First Claim
1. A composite delivery system which comprises a mixture of spray congealed particles having a substantially hydrophobic exterior, the particles which comprise:
- (a) a core material selected from the group consisting of sweeteners, flavoring agents, and mixtures thereof; and
(b) a hydrophobic encapsulating matrix surrounding the core, wherein the matrix comprises;
(i) about 0.5% to about 20% fat soluble lecithin;
(ii) about 65% to about 90% of an edible material having a melting point in the range of about 25°
C. to about 100°
C. selected from the group consisting of (a) a fatty acid having an iodine value of about 1 to about 10;
(b) natural waxes;
(c) synthetic waxes; and
(d) mixtures thereof;
(iii) about 0.5% to about 20% of a glyceride; and
(iv) a silicone based anti-foaming agent in a concentration of about 0.001% to about 0.5%;
said composite delivery system having a melting point in the range of from about 20°
C. to about 90°

Abstract
The present inventive composition concerns a composite delivery system having a substantially hydrophobic exterior comprising:
(a) an agglomerated mixture of a core material selected from the group consisting of sweeteners, flavoring agents and mixtures thereof and a matrix wherein the matrix comprises:
(i) about 0.5% to about 20% fat soluble lecithin;
(ii) about 65% to about 90% of an edible material having a melting point in the range of about 25° C. to about 100° C. selected from the group consisting of (a) a fatty acid having an iodine value of about 1 to about 10; (b) natural waxes; (c) synthetic waxes; and (d) mixtures thereof,
(b) about 0.5% to about 20% of a glyceride; and
(c) a silicone based anti-foaming agent in a concentration of about 0.001% to about 0.5%; said composite having a melting point in the range of about 20° C. to about 90° C.

14. A method of preparing a composite sweetener delivery system, which comprises:
-
preparing a hydrophobic encapsulating matrix containing about 0.5% to about 20% fat soluble lecithin, about 65% to about 90% of an edible material having a melting point in the range of about 25°
C. to about 100°
C. selected from the group consisting of (a) a fatty acid having an iodine value of about 1 to about 10, (b) natural waxes, (c) synthetic waxes, and (d) mixtures thereof;mixing said matrix; melting said encapsulating matrix material at a temperature above about 60°
C.;adding an anti-foaming agent to said matrix and mixing until a homogeneous mixture is obtained; mixing a glyceride into said matrix, followed by adding a sweetening agent to the matrix to encapsulate the sweetening agent; and spray drying the resulting composition to form a composite sweetener delivery system comprising spray congealed particles having a substantially hydrophobic exterior, the particles which comprise a core of sweetening agent encapsulated in the hydrophobic matrix. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
