Abstract
A process for the reduction of the nicotine content of tobacco by microbial treatment is disclosed. Tobacco is subjected, under controlled conditions, to the action of a microorganism effective to degrade nicotine through a biochemical reaction in which, inter alia, 3-succinoylpyridine is formed. Prior to subjecting the tobacco to the action of the microorganism, the tobacco is steamed to increase its moisture content. Tobaccos with lowered nicotine content but no mass loss result from this process following short treatment periods. Also, tobacco treated in accordance with this process, when incorporated into a tobacco smoking product, produces a mild smoke, having a reduced nicotine content. However, there is no loss of desirable flavor, taste and smoking properties.
