Method of controlling release of N-substituted derivatives of aspartame in chewing gum and gum produced thereby
The present invention includes a method for producing a chewing gum with a modified release sweetener selected from the group of N-substituted derivatives of aspartame, particularly neotame, as well as the chewing gum so produced. The modified release neotame or other N-substituted derivative of aspartame sweetener is obtained by physically modifying the sweetener properties by coating and drying. Neotame or another N-substituted derivative of aspartame sweetener is coated by encapsulation, partially coated by agglomeration, entrapped by absorption or extrusion, or treated by multiple steps of encapsulation, agglomeration, absorption, or extrusion. The coated sweetener is then co-dried and particle sized to produce a release-modified high-intensity sweetener. When incorporated into the chewing gum, these particles are adapted to enhance the shelf stability of the sweetener and/or produce a modified release when the gum is chewed.
1. A method of producing a chewing gum product containing a N-substituted derivative of aspartame wherein the N-substituted derivative of aspartame is applied as a part of a rolling compound applied on the chewing gum product.
2. The method of claim 1 wherein an additional high-potency sweetener selected from the group consisting of aspartame, alitarne, salts of acesulfarne, cyclamate and its salts, saccharin and its salts, sucralose, thaumatin, monellin, dihydrochalcone, glycyrrhizin, stevioside and combinations thereof is mixed with the N-substituted derivative of aspartame before it is applied in the rolling compound.
3. The method of claim 1 wherein the N-substituted derivative of aspartame is selected from the group consisting of:
a) N-[N-(3,3-dimethylbutyl)-L-α-aspartyl]-L-phenylalanine 1-methyl ester;
b) N-[N-[3-(4-hydroxy-3-menthoxyphenyl)propyl]-L-α-aspartyl]-L-phenylalanine 1-methyl ester; and
c) N-[N-(3-phenylpropyl)-L-α-aspartyl]-L-phenylalanine 1-methyl ester.
4. The method of claim 1 wherein the N-substituted derivative of aspartame comprises N-[N-(3,3-dimethylbutyl)-L-α-aspartyl]-L-phenylalanine 1-methyl ester.
5. The method of claim 1 wherein the N-substituted derivative of aspartame is incorporated in the rolling compound applied to the product such that it releases from the product more quickly when chewed than if the N-substituted derivative of aspartame were mixed into the chewing gum in an untreated fashion.
6. A method of producing a chewing gum product containing a N-substituted derivative of aspartame wherein the N-substituted derivative of aspartame is applied as a part of a coating on a chewing gum pellet, the coating being formed by a panning procedure.
7. The method of claim 6 wherein an additional high-potency sweetener selected from the group consisting of aspartame, alitame, salts of acesulfame, cyclamate and its salts, saccharin and its salts, sucralose, thaumatin, monellin, dihydrochalcone, glycyrrhizin, stevioside, and combinations thereof is mixed with the N-substituted derivative of aspartame in the coating.
8. The method of claim 6 wherein the N-substituted derivative of aspartame is selected from the group consisting of:
a) N-[N-(3,3-dimethylbutyl)-L-ct-aspartyl]-L-phenylalanine 1-methyl ester;
b) N-[N-[3-(4-hydroxy-3-menthoxyphenyl)propyl]-L-ct-aspartyl]-L-phenylalanine 1-methyl ester; and
c). N-[N-(3-phenylpropyl)-L-cc-aspartyl]-L-phenylalanine 1-methyl ester.
9. The method of claim 6 wherein the N-substituted derivative of aspartame comprises N-[N-(3,3-dimethylbutyl)-L-α-aspartyl]-L-phenylalanine 1-methyl ester.
10. The method of claim 6 wherein the N-substituted derivative of aspartame is incorporated in the panned coating on the product such that it releases from the product more quickly when chewed than if the N-substituted derivative of aspartame were mixed into the chewing gum in an untreated fashion.
11. A coated chewing gum product comprising:
a) a chewing gum pellet;
b) a coating on the pellet formed by a panning procedure and comprising an N-substituted derivative of aspartame.
12. The coated chewing gum product of claim 11 wherein the N-substituted derivative of aspartame comprises N-[N-(3,3-d methylbutyl)-L-α-aspartyl]-L-phenylalanine 1-methyl ester.
13. A chewing gum product comprising:
a) a chewing composition formed into a chewing gum piece; and
b) a rolling compound on the piece comprising an N-substituted derivative of aspartame.
14. The chewing gum product of claim 13 wherein the N-substituted derivative of aspartame comprises
N-[N-(3,3-dimethylbutyl)-L-α-aspartyl]-L-phenylalanine 1-methyl ester.
