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.

A smoking article may include a cigarette incorporated within an electrically powered aerosol generating device that acts as a holder for that cigarette. The smoking article possesses at least one form of tobacco. The smoking article also possesses a mouth-end piece that is used by the smoker to inhale components of tobacco that are generated by the action of heat upon components of the cigarette. A representative smoking article possesses an outer housing incorporating a source of electrical power (e.g., a battery), a sensing mechanism for powering the device at least during periods of draw, and a heating device (e.g., at least one electrical resistance heating element) for forming a thermally generated aerosol that incorporates components of tobacco. During use, the cigarette is positioned within the device, and after use, the used cigarette is removed from the device and replaced with another cigarette.
