The present disclosure provides an aerosol source member and an aerosol delivery device that includes an aerosol source member. The aerosol source member includes a segmented substrate portion that includes a first substrate segment and a second substrate segment. The first substrate segment includes a first aerosol former, the second substrate segment includes a second aerosol former different from the first aerosol former, and the second substrate segment is positioned between the first substrate segment and a downstream end of the aerosol source member. The first substrate segment and the second substrate segment are configured such that when heated by a heat source, the first substrate segment is heated to a first temperature and the second substrate segment is heated to a second temperature that is less than the first temperature.

Aerosol delivery device including a segregated substrate

A smokeless tobacco pastille configured for insertion into the mouth of a user is provided. The smokeless tobacco pastille can include (i) a tobacco material present in an amount of less than about 40 dry weight percent, based on the total dry weight of the pastille; (ii) at least one natural gum binder present in an amount of at least about 25 dry weight percent; and (iii) a plurality of sugar alcohols present in a total amount of at least about 40 dry weight percent, the predominant component of the plurality of sugar alcohols being isomalt or erythritol, wherein the shape of the smokeless tobacco pastille is moldable in the oral cavity.

Smokeless tobacco pastille

A method for preparing an aerosol precursor composition is provided, which includes the steps of providing a first aqueous solution comprising one or more organic acids in water; subjecting the first aqueous solution to hydrolysis to give a hydrolyzed aqueous solution with a higher organic acid monomer content on a dry weight basis than in the first aqueous solution; and combining the hydrolyzed aqueous solution with one or more aerosol formers to give an aerosol precursor composition. Typically, the aerosol precursor composition further contains nicotine. The disclosed method can lead to enhanced control over the composition and characteristics of the produced aerosol precursor composition.

Method for hydrolysis of lactic acid for aerosol delivery device

A smokeless tobacco product configured for insertion into the mouth of a user of the product is provided, the smokeless tobacco product including a dissolvable or meltable base composition admixed with a tobacco material and a botanical material, wherein the botanical material is present in an amount of at least about 0.1% of the total dry weight of the smokeless tobacco product. The botanical material and the smokeless tobacco product can be characterized based on antioxidant content using the ORAC index or the FRAP index. An exemplary product has an ORAC index value of at least about 20 (&#x3bc;mol TE)/g or a FRAP index value of at least about 50 (&#x3bc;mol/Fe)/g.

Smokeless tobacco composition incorporating a botanical material

A method of modifying the content of certain chemical compounds in tobacco materials is provided, the method including treatment of a tobacco plant or portion thereof with at least one enzyme. For example, the method may modify the content of tobacco smoke toxicant precursors in tobacco materials, which can result in a modification in toxicant production when the tobacco material is exposed to elevated temperatures. The type of tobacco plant or portion thereof treated according to the invention can be, for example, a tobacco seed, a tobacco seedling, an immature live plant, a mature live plant, a harvested plant, or a plant derivative. Smoking articles and other tobacco products including such enzyme-treated tobacco materials are also provided.

Method for treating tobacco plants with enzymes

Provided are smoking products and methods of preparing smoking products that include tobacco and a deflavored rosemary or a heat-treated rosemary. The deflavored and/or heat-treated rosemary may have been previously heated at a temperature and a time sufficient to reduce or remove flavorant components compared to the use of untreated rosemary. The heated rosemary may include one or more pentacyclic triterpenoid acids such as betulinic, betul-18-enoic, oleanolic, and ursolic acids.

Rosemary in a tobacco blend

The present invention discloses genetically modified tobacco plants, and tobacco products derived from such plants, comprising a decrease in at least one amino acid such that upon heating and/or burning, the tobacco plant or a portion thereof generates reduced levels of a compound derived from the at least one amino acid as compared to an unmodified parent tobacco plant or a portion thereof. In an embodiment, the tobacco generates reduced levels of acrylamide and/or acrylonitrile upon heating and/or burning of the tobacco as compared to an unmodified parent tobacco line. These plants are useful for improving tobacco products.

Tobacco having reduced amounts of amino acids and methods for producing such lines

A method of modifying the content of certain bacteria in uncured tobacco material is provided, the method including contacting an uncured tobacco material with a treatment solution, wherein the treatment solution is selected from the group consisting of: (i) a solution comprising salt, sugar, or a combination thereof; (ii) a solution comprising one or more enzymes; and (iii) a solution comprising one or more probiotics, wherein said contacting provides a treated tobacco material having a reduced total bacterial content following harvest. In certain embodiments, the treated tobacco material is subsequently cured, and can optionally be fermented. Smoking articles and smokeless tobacco products including such treated tobacco materials are also provided.
