    摘要： A method of modifying the content of certain chemical compounds in tobacco materials is provided, the method including treatment of a tobacco plant component with at least one probiotic. For example, the method may modify the asparagine content in tobacco materials, which can result in a modification in acrylamide production when the tobacco material is exposed to elevated temperatures. The type of tobacco plant component treated according to the invention can be a tobacco seed, a tobacco seedling, an immature live plant, a mature live plant, a harvested plant, or a portion thereof. Examples of probiotics include probiotic species of the genera bifidobacterium, lactobacillus, enterococcus, proionobacterium, bacillus, saccharomyces, streptococcus, and mixtures thereof. Smoking articles and other tobacco products including such probiotic-treated tobacco materials are also provided.

    摘要： Methods of forming cellulosic sugars from the stalk or roots of a plant of the Nicotiana species are provided herein, the methods including i) receiving a tobacco material including at least one of a stalk material and a root material of a harvested plant of the Nicotiana species; ii) delignifying the tobacco material to form a tobacco-derived pulp; and iii) hydrolyzing the tobacco-derived pulp to form a hydrolyzed tobacco product including residual solids and a liquid including at least one tobacco-derived cellulosic sugar. A cellulosic sugar derived from hydrolyzed tobacco material including at least one of a tobacco stalk material and a tobacco root material of a harvested plant of the Nicotiana species is also provided herein. Tobacco products incorporating the cellulosic sugars derived from hydrolyzed tobacco material or products derived from the cellulosic sugar are also provided.

    摘要： This invention provides a method for removing undesirable constituents from tobacco which includes extracting tobacco material in an aqueous or organic solvent and filtering the product of the extraction using a horizontal belt filter. The extract and insoluble tobacco residue may be further treated enzymically, chemically or otherwise to remove a complement of undesirable constituents. The extract and insoluble tobacco residue are recombined to form a regenerated tobacco material that is less harmful when combusted than the original material.

    摘要： L'invention se rapporte à un procédé permettant de réduire la teneur en protéine du tabac, et qui consiste à extraire le tabac à l'aide d'un agent tensioactif et, éventuellement, d'une enzyme protéolytique. Le tabac peut d'abord être extrait au moyen d'un solvant aqueux afin de produire un extrait aqueux, avant d'être traité par l'intermédiaire de l'agent tensioactif. L'invention se rapporte également à un procédé permettant d'enlever des polypeptides à partir d'un extrait aqueux de tabac, et qui consiste à traiter l'extrait au moyen d'un agent adsorbant insoluble choisi dans le groupe composé d'hydroxyapatite et d'un minerai d'argile à foulon tel que la bentonite. Le traitement d'un extrait aqueux au moyen de la bentonite permet d'obtenir un extrait à teneur réduite en pigment et en polypeptide.

    摘要： The use of unexpanded tobacco is not as cost effective as expanded tobacco. This disclosure relates to a process for the treatment of tobacco materials so as to enhance puffing. More particularly, the disclosure relates to a process that comprises contacting tobacco with an aqueous enzyme solution exhibiting cellulase activity, incubating the tobacco-enzyme mixture, and thereafter expanding the tobacco material. Tobacco materials treated in this manner exhibit an enhanced capability for expansion, thereby resulting in a significant increase in filling capacity when compared to untreated expanded tobacco.
