Abstract:
1. A delivery system having a preselected desired release profile of at least one active component, suitable for incorporation into an edible composition, comprising a mixture of at least one active component, at least one tensile strength modifying agent, and at least one encapsulating material; wherein the at least one encapsulating material forms a matrix with the at least one active component, whereby the at least one encapsulating material completely encapsulates the at least one active component; wherein the presence of the at least one tensile strength modifying agent modifies the tensile strength of the delivery system; wherein the at least one active component in an amount of about 5 wt % to about 55 wt % by weight of the delivery system and the at least one encapsulating material is present in an amount of about 45 wt % to about 95 wt % by weight of the delivery system and wherein the weight ratio of the at least one active component to the at least one encapsulating material is of from 1:99 to 70:30; wherein the at least one tensile strength modifying agent is selected from the group consisting of hydrogenated vegetable oils, talc, dicalcium phosphate, calcium carbonate, and combinations thereof and is present in an amount from about 1% to about 40% by weight based on the weight of the delivery system, with the proviso that when the tensile strength modifying agent is one or more hydrogenated vegetable oils it is present in an amount of 1% to 5% by weight based on the total weight of the delivery system; wherein the at least one encapsulating material is selected from the group consisting of polyvinyl acetate, crosslinked polyvinyl pyrrolidone, polylactic acid, polyhydroxyalkanoates, and combinations thereof; wherein the delivery system has a desired release profile of the at least one active component provided by the combination of (1) adding a preselected amount of the at least one tensile strength modifying agent in the range of 1% to 40% by weight based on the total weight of the delivery system and (2) employing an encapsulating material having a preselected hydrophobicity having a water-retention value of up to 50% as measured by ASTM D570-98 thereby obtaining an overall tensile strength of the delivery system that corresponds to the preselected desired release profile of the at least one active component; and wherein the delivery system has a tensile strength of at least 10,000 psi and average particle size of about 125 microns to about 900 microns.
