Abstract: A system for a tobacco curing barn is capable of collecting tobacco-derived moisture from tobacco while that tobacco is cured. The system incorporates a tobacco curing barn or other type of curing enclosure, such as bulk curing barn used for the flue-curing of tobacco. The curing barn is equipped with at least one reclamation element configured to condense and collect moisture released from tobacco cured within the barn. The reclamation element is disposed in proximity with the enclosure in a manner and location providing passage of moist air released from the tobacco across a surface of the reclamation element. The system also includes at least one storage container disposed in fluid communication with the reclamation element surface and configured to store moisture and moisture-borne material collected by the reclamation element. The resulting tobacco-derived components can be blended with other tobacco materials, such as is common practice during tobacco reordering.

Abstract: A process for producing flavorants made or derived from tobacco or, more generally, made or derived from any biomass derived from any one or more species of genus Nicotiana, or that otherwise incorporate tobacco, is provided. Provided are flavorants obtained or derived from plants or portions of plants from the Nicotiana species, such as from one or more flowers from one or more Nicotiana species, and products comprising one or more such flavorants.

Abstract: A filtered cigarette includes a smokable rod and a filter element. The smokable rod is secured to the filter element using tipping material. The tipping material includes at least one flavorant providing a sensory characteristic. The cigarette may include more than one layer of tipping material. An outer layer of tipping material can overlie at least a portion of an underlying inner layer of tipping material, and during use by the smoker, the outer layer can be removed from the cigarette. Thus, it is possible for a cigarette manufacturer to provide a cigarette that can be used as such by the smoker, or that can be adapted by the smoker to provide a different sensory experience (e.g., the visual, organoleptic, trigeminal, aromatic, and tactile characteristics of the cigarette can be altered by removal of the outer tipping material, and or by provision of a tipping material layer that is treated with a flavorant and/or provides a desirable diffusivity).

Abstract: Cigarette sidestream smoke can have the aroma thereof altered by placing the cigarette wrapping paper in intimate contact with a flavor precursor such as ethyl vanillin glucoside. The cigarettes exhibit good tobacco taste during use. The flavor precursor provides no substantial aroma to the cigarette prior to use thereof, and a characteristic aroma of the flavoring agent in the sidestream smoke during use thereof. Cigarettes can have a wrapping paper containing magnesium oxide and/or magnesium hydroxide, the paper having a net permeability of greater than 50 CORESTA units and an inherent permeability of less than 45 CORESTA units. The paper containing magnesium oxide and/or magnesium hydroxide is in intimate contact with a flavor precursor, and the filter of the cigarette includes a flavor carrier such as a flavored pellet.

Abstract: Cigarettes having low efficiency filters, rods of cut filler having a low packing density, and paper wraps having a high net permeabilities and low inherent permeabilities can yield good taste, low gas phase mainstream deliveries as well as low amounts of visible sidestream smoke. Typical cigarettes have relatively large amounts of volume expanded flue-cured tobacco materials as cut filler, paper wraps containing magnesium oxide and/or magnesium hydroxide, and relatively high levels of air dilution.

Abstract: In one aspect, the invention provides a simple, readily manufacturable, low tar cigarette with individual puff deliveries similar to those obtained from conventional cigarettes which have a higher total smoke delivery such as a full flavor cigarette. The low tar cigarette includes a tobacco rod segment having a length of 53 mm. or less abutting a filter segment having an overall length of at least 31 mm. wherein the filter segment includes a synthetic fiber filter plug and provides a smoke delivery reduction of at least 55% and wherein the cigarette has an average puff count of 6.5 or less. In another aspect, the invention provides nonconventional smoking articles which have an elongated nonsmokable mouthend portion, i.e.

Abstract: A cold trap for collecting components of an aerosol stream comprises an elongated vessel provided with an aerosol stream inlet and an aerosol stream outlet, a cooling jacket for subjecting a substantial portion of the walls of the vessel to temperatures below 0.degree. C. and a baffle assembly that includes a plurality of spaced baffle plates which cooperate to present a tortuous path to the flow of the aerosol stream as it moves through the vessel.
