Process for obtaining tobacco leaves with a standardized nicotine content and/or improved combustibility

摘要

Process for the preparation of tobacco leaves with a standardized nicotine content and/or improved combustibility, for use in the manufacture of smoking products such as cigarettes, cigars and shags. The method includes drying and curing of tobacco leaves (Nicotiana tabacum), extraction of the dried leaves with a mixture of organic solvent and water, re-drying of the extracted leaves to a controlled moisture value, and finally, elimination of the ribs. The leaves thus obtained are suitably mixed with excipients and flavourings, and shredded to make cigarettes, cigars, etc . . .
