Abstract

The use of pectins and/or polymers to prevent nicotine oxidation in tobacco containing products is disclosed. These polymers may be naturally occurring anionic polymers or synthetic polymers. These pectins and/or polymers prevent nicotine from oxidizing into cotinine, nicotine-cis-N-oxide, nicotine-trans-N-oxide, and/or nicotine-1,1-di-N-oxide. Molluscicides, algaecides, pesticides, and stabilized nicotine compositions comprising nicotine and pectin, anionic polymers, or combinations thereof are disclosed.

Claims (39)

1. A pouched product comprising:

reconstituted tobacco; and

a mixture including,

nicotine in an amount ranging from 1 weight percent to 30 weight percent, and

a stabilizing composition in an amount ranging from 70 weight percent to 90 weight percent, the stabilizing composition including,

pectin, a carboxylated polymer, a sulfated polymer, a phosphorylated polymer, or any combination thereof.

2. The pouched product of claim 1 , further comprising:

a tobacco extract, the tobacco extract including, the nicotine.

3. The pouched product of claim 1 , wherein the nicotine and the stabilizing composition are in the form of a complex.

4. The pouched product of claim 1 , wherein the stabilizing composition includes the pectin.

5. The pouched product of claim 4 , wherein the pectin is electrostatically attracted to the nicotine.

6. The pouched product of claim 4 , wherein the pectin includes tobacco pectin.

7. The pouched product of claim 6 , wherein the tobacco pectin is configured to prolong release of the nicotine from the pouched product during exposure to saliva.

8. The pouched product of claim 6 , wherein the tobacco pectin includes unwashed tobacco pectin.

9. The pouched product of claim 6 , wherein the tobacco pectin includes dialyzed tobacco pectin.

10. The pouched product of claim 4 , wherein the pectin includes apple-derived pectin, citrus-derived pectin, sugar beet-derived pectin, sunflower-derived pectin, mango-derived pectin, or any combination thereof.

11. The pouched product of claim 1 , wherein

the stabilizing composition includes the carboxylated polymer, and

the carboxylated polymer includes carboxymethylcellulose, alginate, alginic acid, or any combination thereof.

12. The pouched product of claim 1 , wherein

the stabilizing composition includes the sulfated polymer, and

the sulfated polymer includes carrageenan, fucoidan, heparan sulfate, heparin, or any combination thereof.

13. The pouched product of claim 1 , wherein

the stabilizing composition includes the phosphorylated polymer, and

the phosphorylated polymer includes deoxyribonucleic acid (DNA), ribonucleic acid (RNA), or both DNA and RNA.

14. The pouched product of claim 1 , wherein the stabilizing composition is configured to reduce oxidation of the nicotine into cotinine, nicotine-cis-N-oxide, nicotine-trans-N-oxide, nicotine-1,1-di-N-oxide, or any combination thereof.

15. A pouched product comprising:

a wrapper; and

a releasable composition on the wrapper, the releasable composition including,

nicotine in an amount ranging from 1 weight percent to 30 weight percent of the releasable composition, and

a stabilizing composition in an amount ranging from 70 weight percent to 99 weight percent of the releasable composition, the releasable composition including,

pectin, a carboxylated carbohydrate polymer, a sulfated polymer, a phosphorylated polymer, or any combination thereof.

16. The pouched product of claim 15 , wherein the stabilizing composition includes the pectin.

17. The pouched product of claim 15 , wherein the pectin includes tobacco pectin.

18. The pouched product of claim 15 , wherein the pectin includes unwashed tobacco pectin, dialyzed tobacco pectin, or both unwashed tobacco pectin and dialyzed tobacco pectin.

19. A pouched product comprising:

nicotine in an amount ranging from 1 weight percent to 30 weight percent, and

a stabilizing composition in an amount ranging from 70 weight percent to 90 weight percent, the stabilizing composition including,

a sulfated polymer including deoxyribonucleic acid (DNA), ribonucleic acid (RNA), or both DNA and RNA.
