FIELD: production of recovered tobacco material.
SUBSTANCE: method involves subjecting natural tobacco material to extraction process using solvent for producing of extracted solution containing components of natural tobacco material and extraction residue; subjecting resultant extracted solution to fractioning processing using ultra-filtration, reverse osmosis filtration or reverse-phase high performance liquid chromatography to obtain first fraction enriched with desired components and impoverished with undesired components, and second fraction enriched with undesired components and impoverished with desired components; obtaining recovered tobacco sheet from extraction residue; adding first fraction to recovered tobacco sheet, possibly in conjunction with reduced amounts of second fraction.
EFFECT: increased efficiency by providing adjustable reduction of cancer-inducing substances in smoke on smoking of tobacco articles, and reduced burning rate of tobacco articles.
