A METHOD FOR THE REDUCTION OF TOBACCO SPECIFIC NITROSAMINES BY INCREASING ANTIOXIDANTS IN TOBACCO

摘要

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.
