Abstract: A fuel element adapted for use in a smoking article is provided, the fuel element including a combustible carbonaceous material in an amount of at least 25% by dry weight, based on the weight of the fuel element, and a particulate ignition aid dispersed throughout the fuel element and selected from ceramic particles, cellulose particles, fullerenes, impregnated activated carbon particles, inorganic salts, and combinations thereof, wherein the average particle size of the ignition aid is less than about 1,000 microns. Also provided are elongate smoking articles having a lighting end and an opposed mouth end, and including the above-noted fuel element configured for ignition of the lighting end.

Abstract: Ribulose-1,5-bisphosphate oxygenase (RuBisCO) protein fibers and a method of producing them are disclosed herein. The method of producing one or more RuBisCO protein fibers including obtaining RuBisCO, for example from tobacco, combining the RuBisCO with one or more plasticizers, heating the combination of the RuBisCO and the one or more plasticizers up to about 140 degrees C., filtering the heated combination through an about 20 μm filter, and passing the filtered combination through an orifice to produce one or more RuBisCO protein fibers.

Abstract: A filter material adapted for use as a filter element of a smoking article is provided, the filter material being in the form of a fibrous tow that includes a plurality of filaments of a degradable polyester and a plasticizer composition applied thereto, the plasticizer composition and the degradable polyester having a Relative Energy Difference calculated using Hansen Solubility Parameters of less than about 1.3. Exemplary degradable polyesters include polyglycolic acid, polylactic acid, polyhydroxyalkanoates, polycaprolactone, polybutylene succinate adipate and copolymers or blends thereof. Exemplary plasticizer compositions include one or more of dimethylisosorbide, propylene carbonate, methylbenzyl alcohol, glycerol carbonate acetate, glycerol carbonate ethyl ether, and mixtures thereof, optionally in combination with triacetin. Filter elements and smoking articles, such as cigarettes, that contain the filter material are also provided.

Abstract: Ribulose-1,5-bisphosphate oxygenase (RuBisCO) protein films and a method of producing RuBisCO films are disclosed herein. A method of producing one or more RuBisCO protein films includes obtaining RubBisCO, for example from tobacco, combining the RuBisCO with one or more solvents, where the one or more solvents may be about 10% w/v the RuBisCO, mixing the RuBisCO and the one or more solvents to form a slurry, heating the slurry to about 70 degrees C., cooling the slurry to at least about 45 degrees C., dispensing the slurry into one or more molds for film formation, drying the slurry in the one more molds, and removing the one or more RuBisCO protein films formed within the one or more molds.
