Abstract: Abstract The present invention is drawn to methods for reducing tobacco-specific nitrosamine (TSNA) content in cured tobacco by increasing the levels of antioxidants in the tobacco prior to harvesting. Methods to be used in the present invention include root pruning of the tobacco plant prior to harvesting; severing the xylem tissue of the tobacco plant prior to harvesting; and administering antioxidants and/or chemicals which increase antioxidants to the tobacco plant after harvesting.

Abstract: Methods for increasing the concentration of antioxidants during senescence and curing of tobacco leaves include application of a chemical solution. The methods include spraying the solution onto the tobacco plant prior to harvest and/or applying the chemical solution to the soil surrounding roots of growing tobacco plants. The application of the chemical solution preferably occurs between topping and harvest, and is optimized to stimulate the production of antioxidants and interfere with the formation of TSNAs during curing. The tobacco can be burley tobacco subjected to air curing.

Abstract: Delivery of additives in a smoking article (200) is provided through thermally degradable, robust immobilized additive inserts (100). Additives can be immobilized in an elongated device (110) or an insert, wherein the elongated device (110) or the insert is sufficiently robust to allow the elongated device (110) or the insert to be manually or machine inserted into a smoking article (200) while maintaining the structure of the elongated device (110) or the insert. By providing additives in the form of thermally degradable immobilized additive inserts (100), migration and/or loss of the additives in a smoking article (200) prior to smoking can be reduced.

Abstract: A tobacco rod having reduced levels of at least one phenolic compound precursor selected from the group consisting of gentisic acid, 3,4-dihydroxybenzoic acid, chlorogenic acid, rutin, scopoletin, quinic acid, a quinic acid derivative, caffeic acid, inositol and lignin. The concentration in mainstream smoke of phenolic compounds such as phenol, hydroquinones (e.g., hydroquinone, methyl hydroquinone and 2, 3-dimethyl hydroquinone), catechols (e.g., p-coumaryl quinic acid, feruloyl quinic acid and syringoyl quinic acid) and cresols (e.g., o-cresol, m-cresol and p-cresol) can be reduced by reducing the concentration in uncured (e.g., green) or cured tobacco of the phenolic compound precursors. The concentration of phenolic compound, precursors in tobacco can be reduced by forming an extract of tobacco solubles, removing phenolic compound precursors from the extract by treating the extract with polyvinylpolypyrrolidone or polyvinylimidazole in the absence of an enzyme to form a treated extract; and restoring the treated extract to the tobacco.
