Publication number: 20210345658Abstract: 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.Type: ApplicationFiled: July 23, 2021Publication date: November 11, 2021Inventors: Jerry Wayne Marshall, Serban C.

Patent number: 7293564Abstract: A method for chemically modifying a tobacco material during a curing process involves treating the tobacco material in a curing enclosure at a temperature and for a time sufficient to produce cured tobacco. The method also involves contacting the tobacco material with a chemical reagent before and/or during the time period that the tobacco material is cured so that the chemical reagent can interact with the tobacco material, thus resulting in further change in the chemical nature of the cured tobacco material. An exemplary chemical reagent is an ammonia source, which can be applied to a tobacco material in a variety of ways, including by spraying an aqueous ammonia source onto the tobacco or by introducing gaseous ammonia into the curing enclosure during the curing process.Type: GrantFiled: June 11, 2003Date of Patent: November 13, 2007Assignee: R.
