  • Publication number: 20110100382
    Abstract: Oral tobacco products having a gel-coating and methods for making are provided. The method includes (a) molding a portion of tobacco material to form a pre-portioned piece of tobacco material, the tobacco material comprising moist smokeless tobacco; (b) contacting the pre-portioned piece of tobacco material with a gel-coating solution to form a gel-coating comprising at least one polymer on an outer surface of the pre-portioned piece of tobacco material to form a gel-coated oral tobacco product, said gel-coating comprising an inner surface disposed around the pre-portioned piece of tobacco material and an outer surface; and (c) forming one or more of perforations, uncoated areas and holes in the gel-coating of the oral tobacco product to form a gel-coated oral tobacco product.

  • Publication number: 20110083681
    Abstract: A process for preparing coated particles of a plant material includes: (a) combining plant material particles and a protein in a liquid medium, wherein the protein adsorbs onto at least a portion of a surface of the particles to form a first layer; and (b) mixing a polysaccharide including a pectin with the liquid medium, so that the polysaccharide adsorbs onto at least a portion of a surface of the first layer to form a second layer. In addition, a palatable product comprising at least one coated particle prepared by this process is described.

  • Publication number: 20110083686
    Abstract: Provided are a method and apparatus for making a cigarette filter assembly for potentially reducing particle breakthrough. The method includes forming a lofty porous network of charge retaining polymer fibers by mechanical, chemical or thermal bonding of the fibers, wrapping the lofty porous network in a cylindrical or tubular shape with optional mediating filter fibers in a filter paper to form a filter plug while maintaining the lofty structure. The charge retaining fibers can be charged to attract and hold particles from such sources as particulate matter from sorbents (preventing break-through), and smoke constituents while having a suitable pressure drop. The apparatus handles the lofty media with minimal crushing, for example, by spacing apart delivery rolls equipped with protrusions to punch, push, and/or pull the lofty media ahead for high speed operation.

  • Publication number: 20110083682
    Abstract: A process of manufacturing a reconstituted tobacco material is provided which includes: preparing a heated mixture of water and sugar; providing a liquid flavorant such as menthol; mixing tobacco particles, water and a gum binder with the mixture of water and sugar and with the flavorant to form a reconstituted tobacco mixture; and forming the reconstituted tobacco mixture, such as by casting or extruding the reconstituted tobacco mixture, into a reconstituted tobacco material. Exemplary menthol reconstituted tobacco products provided herein enable high levels of menthol to be retained in a tobacco product.

  • Publication number: 20100006112
    Abstract: Provided is a cigarette filter and method of making the filter. The filter includes an adsorbent dispersed within the filter and a downstream plug of randomly-oriented fibers. The randomly-oriented fibers mechanically capture adsorbent particles entrained in tobacco smoke. One or more plugs of axially-oriented fibers may also be located upstream and/or downstream of the adsorbent, and are included in an amount sufficient to adjust the length of the filter.

  • Publication number: 20080314400
    Abstract: Provided is a cigarette filter and method for potentially reducing particle breakthrough. The filter includes an adsorbent including adsorbent particles dispersed within the filter and a plug of electrostatically charged fibers. Preferably, the adsorbent is activated carbon. In a preferred embodiment, the electrostatically charged fiber material is located downstream of the activated carbon. Preferably, the electrostatically charged fiber material has permanent electrostatic charges that electrostatically capture the carbon particles to reduce carbon particle breakthrough. In an embodiment, the electrostatically charged fiber material is randomly-oriented so as to mechanically capture particles entrained in mainstream smoke.

  • Publication number: 20080295854
    Abstract: Wrapper for cigarette manufacture includes transversely extending band regions applied by a printing technique, such as gravure printing. The band regions comprise starch, an anti-wrinkling agent such as 1,2 propylene glycol or glycerin, and optionally calcium carbonate. Any suitable printing technique can be used to apply the aqueous solution to the banded regions. The pattern of banded regions may be bands, stripes, two-dimensional arrays, undulated regions, and the like along and/or around the tobacco rod. The pattern can be applied in one or more layers. The pattern may be configured so that when a smoking article is placed on a substrate, at least two longitudinal locations along the length of the tobacco rod have film-forming compound located only on sides of the smoking article not in contact with the substrate.
