Smokable rods of cigarettes are manufactured using wrapping materials that incorporate at least one fibrous material (e.g., flax fibers, hardwood pulp fibers and/or softwood pulp fibers) at least one filler material (e.g., calcium carbonate in particulate form). The wrapping materials possess multi-layer coatings. The wrapping materials possess coatings in the form of series of spaced apart bands, each band possessing a series of layers. At least one of the coating layers can have a filler material dispersed or suspended within a film-forming material of that layer.

Wrapping materials for smoking articles

A smoking article is provided having improved flavor and aroma when smoked and contains one or more smokable materials having free amino acids contained therein. The smoking article comprises a selectively enriched content of at least one amino acid selected from the group consisting of serine, threonine and analogs thereof, and is substantially free of exogenous non-sugar Maillard-functional carbonyl compounds.

Smoking article having increased amino acid content

A flavorful and aromatic composition is provided by forming a mixture of a first component in the form of at least one non-sulfur containing amino acid, non-sulfur containing amino acid analog and/or degradation product thereof and a second component in the form of at least one sugar, sugar analog and/or degradation product thereof. The first component and second component are in a molar ratio of from about 1:1 to about 60:1. The mixture is then subjected to heat treatment in a pressure controlled environment under conditions sufficient to form the flavorful and aromatic composition, e.g., a pressure of about 10 psig to about 1000 psig and a temperature of at least 100.degree. C. The composition is useful as casing and top dressing components for tobacco laminae and cut filler, as well as for other smokable materials.

Method for producing a flavorful and aromatic composition for use in

A flavorful and aromatic compound for use in a smoking article is provided by subjecting an amino acid having a hydroxy group to heat treatment at a pressure of about 10 psig to about 1000 psig and at a temperature of at least about 100.degree. C. to provide a reaction material including flavorful and aromatic composition, and collecting the flavorful and aromatic composition for use in altering the aroma of mainstream smoke upon burning of a smoking compound during use.

Method of providing flavorful and aromatic compounds

A process is provided for treating tobacco material for use in a smoking article comprising the step of applying a flavorful and aromatic casing and top dressing composition comprising a weak ammonium salt and a sugar or sugar derivative to a tobacco material. The present also provides a smoking article including tobacco material wherein the tobacco material is in intimate contact with a casing and top casing composition comprising a weak ammonium salt and a sugar or sugar derivative.

Tobacco treatment process

A smoking article includes a short, combustible, carbonaceous fuel element in a heat exchange relationship with a substrate carrying glycerin, tobacco extract, and a portion of an essential oil gland bearing plant. For example, fragments of cinnamon bark, lovage root, chamomile flowers or cardamon physically separate from the fuel element provide for a controlled release of a flavor profile during use of the smoking article. Heat provided by the burning fuel element acts to release essential oils from the glands to provide a complex flavor and aroma profile. The smoking article is capable of providing the user with many of the pleasures of smoking by heating but not necessarily burning tobacco.

Smoking article

Cigarettes have a smokable filler blend comprising 60 to 75 percent tobacco cut filler and 25 to 40 percent of a second smokable cut filler consisting essentially of 50 to 70 percent calcium carbonate, 15 to 45 percent pyrolyzed cotton linters, and 7 to 12 percent polysaccharide binder. The blend is contained in a paper wrapper having a permeability from about 40 to about 75 CORESTA units. Cigarettes normally include a filter element and are air diluted to an air dilution level of from 40 to 65 percent. The smokable blend preferably is blended with a tobacco essence, and the nicotine content of the blend is greater than 2 percent. Cigarettes exhibit resistances to draw between 80 and 150 mm water pressure drop at 17.5 cc/sec. air flow. Cigarettes exhibit FTC 'tar' to nicotine ratios less than 9.
