  • Publication number: 20160095350
    Abstract: A process for preparing a filter plug for a smoking article, such as a cigarette, includes: (a) freeze-drying a solution of a biopolymer to form a structure; and (b) cutting the structure to a predetermined dimension, to thereby prepare a filter plug for a smoking article. Another process for preparing a filter plug for a smoking article, such as a cigarette, includes: (a) extruding a mixture of a foaming agent and a biopolymer comprising a protein to form a structure; and (b) cutting the structure to a predetermined dimension, to thereby form a filter plug for a smoking article.

  • Publication number: 20150359258
    Abstract: Disclosed is a smoking article containing a rod containing a smokable composition, an optional wrapper for the rod, and at least one polymer or oligomer comprising monomer units of a polycarboxylic acid ester disposed on or in the rod, the wrapper, or both. The polycarboxylic acid ester contains an acid moiety having at least two carboxylic groups, and at least two alcohol moieties independently selected from those corresponding to a cycloalkyl alcohol or an aryl alcohol. The cycloalkyl alcohol or aryl alcohol is a flavorant, or chemesthetic agent, or both. In addition, a method for the controlled release of these flavorant or chemesthetic agents is described, which comprises pyrolyzing at least one polymer or oligomer.

  • Publication number: 20150305398
    Abstract: A pre-portioned moist product comprises a portion of plant material and a coating. Preferably, the plant material comprises tobacco. The coating includes a soluble, non-cross-linkable component and an cross-linkable component which becomes substantially water-insoluble upon crosslinking. The soluble component of the coating dissolves upon placement in the mouth, while the insoluble component disintegrates and/or loses structural integrity once the soluble component has dissolved to release and disperse the plant material in the user's mouth.
