Abstract
A delivery system for one or more sweeteners offers enhanced up front sweetness intensity in combination with prolonged sweetness duration, and improved protection and stability of the active. The delivery system comprises a first high intensity sweetener encapsulated in a first core coating, and a second outer hydrophilic coating containing up to the solubility limit of the second coating of a second sweetener. The resulting delivery system may be incorporated into a variety of comestible products including chewing gums and other confections, baked goods, oral pharmaceuticals and oral hygiene preparations.
Claims32
A sweetener delivery system capable of providing greater up front sweetness while modulating sweetener release and providing greater protection for the sweetener, said sweetener delivery system comprising:
- A. at least one first solid natural or artificial high intensity sweetener selected from the group consisting of amino acid-based sweeteners, chloro derivatives of sucrose, dihydroflavinol, hydroxyguaiacol esters, L-aminodicarboxylic acid gem-diamines, L-aminodicarboxylic acid aminoalkenoic acid ester amides, dipeptide sweeteners, glycyrrhizin, saccharin and its salts, acesulfame salts, cyclamates, steviosides, talin, dihydrochalcone compounds and mixtures thereof;
- B. a first inner coating selected from hydrophobic and hydrophilic coating materials, said inner coating and said first sweetener mixed and prepared to form a core with said first sweetener present in an amount of from about 1% to about 50% by weight of said core;
- and
- C. a second outer coating of a hydrophilic polymer containing a second sweetener, said second outer coating prepared from a solution of the hydrophilic polymer and said second sweetener, with said second sweetener being present in the polymer solution in an amount ranging from about 10% to about 25% by weight of said solution, the outer coating present in an amount of from about 5% to about 50% by weight of said inner coating.
A sweetener delivery system capable of providing greater up front sweetness while modulating sweetener release and providing greater protection for the sweetener, said sweetener delivery system comprising:
- A. at least one first solid natural or artificial high intensity sweetener selected from the group consisting of amino acid-based sweeteners, chloro derivatives of sucrose, dihydroflavinol, hydroxyguaiacol esters, L-aminodicarboxylic acid gem-diamines, L-aminocarboxylic acid aminoalkenoic acid ester amides, dipeptide sweeteners, glycyrrhizin, saccharin and its salts, acesulfame salts, cyclamates, steviosides, talin, dihydrochalcone compounds and mixtures thereof;
- B. an emulsifier selected from the group consisting of lecithin, stearates, ester derivatives of stearates, palmitates, ester derivatives of palmitates, oleates, ester derivatives of oleates, glycerides, ester derivatives of glycerides, sucrose polyesters, polyglycerolesters, and animal waxes, vegetable waxes, synthetic waxes, petroleum wax and mixtures thereof;
- C. a first inner coating of polyvinyl acetate present in amounts of about 20% to about 93% by weight of the total composition and having a molecular weight of about 2,000 to about 14,000;
- and
- D. a second outer coating of a hydrophilic polymer containing a second sweetener, the outer coating prepared from a solution of the hydrophilic polymer and the second sweetener, with the second sweetener being present in the polymer solution in an amount ranging from about 20% to about 25% by weight of said solution, the outer coating present in an amount of from about 5% to about 50% by weight of the inner coating.
A chewing gum composition capable of releasing increased amounts of sweetness evenly over a longer release time comprising a gum base and a sweetener delivery system capable of modulating sweetener release and providing greater protection for the sweetener, said sweetener delivery system comprising:
- A. at least one solid natural or artificial high intensity sweetener selected from the group consisting of amino acid-based sweeteners, chloro derivatives of sucrose, dihydroflavinol, hydroxyguaiacol esters, L-aminodicarboxylic acid gem-diamines, L-aminodicarboxylic acid aminoalkenoic acid ester amides, dipeptide sweeteners, glycyrrhizin, saccharin and its salts, acesulfame salts, cyclamates, steviosides, talin, dihydrochalcone compounds and mixtures thereof;
- B. a first inner core prepared from a coating selected from the group consisting of hydrophobic and hydrophilic coating materials, the sweetener and the core prepared with the sweetener present in an amount of from about 1% to about 50% by weight of said core;
- and
- C. a second outer coating of a hydrophilic polymer containing a second sweetener, the coating prepared from a solution of the hydrophilic polymer and the second sweetener, with the second sweetener being present in the polymer solution in an amount ranging from about 10% to about 25% by weight of said solution, the outer coating present in an amount of from about 5% to about 50% by weight of the first coating.
A chewing gum composition capable of releasing increased amounts of sweetness evenly over a longer release time comprising a gum base and a sweetener delivery system capable of modulating sweetener release and providing greater protection for the sweetener, said sweetener delivery system comprising:
