Abstract
Abstract The present inventive compositions concern a stable delivery system capable of effecting a controlled release of core material comprising: (A) at least one natural or artificial core material selected from the group consisting of amino acid based sweeteners, dipeptide sweeteners, glycyrrhizin, saccharin and its salts, acesulfame salts, cyclamates, steviosides, talin, dihyrochalcone compounds, drugs, medicaments, flavoring agents and mixtures thereof; and (B) a hydrophobic matrix consisting essentially of (i) lecithin; and (ii) 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) fatty acids having an iodine value of about 1 to about 10, (b) natural waxes, (c) synthetic waxes and (d) mixtures thereof; and (iii) at least one glyceride.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
171 words
A stable solid sweetener delivery system in particulate form capable of effecting a controlled release of the sweetener comprising: (A) at least one solid natural or artificial high intensity sweetener present in amounts effective to impart sweetness, said sweetener selected from the group consisting of amino acid based sweeteners, dipeptide sweeteners, glycyrrhizin, saccharin and its salts, acesulfame salts, cyclamates, steviosides, talin, dihyrochalcone compounds and mixtures thereof; and (B) a hydrophobic matrix consisting essentially of (i) lecithin present in sufficient amounts to aid in surface wetting of the sweetener with the hydrophobic matrix; and (ii) an edible material present in amounts sufficient to provide a fully protective barrier for said sweetener having a melting point in the range of about 25° C. to about 100° C. selected from the group consisting of (a) fatty acids having an iodine value of about 1 to about 10, (b) natural waxes, (c) synthetic waxes and (d) mixtures thereof; and (iii) at least one glyceride present in sufficient amounts to impart flexibility to the hydrophobic matrix.
