Abstract
A heated aerosol-generating article is provided, including an aerosol-forming substrate including tobacco and a metal-based sulphide scavenger compound, an amount of a metal component of the sulphide scavenger compound in the aerosol-forming substrate is at least 0.05 percent by weight, based on a total dry weight of the aerosol-forming substrate, and the sulphide scavenger compound is based on a transition metal.

-12. (canceled)
A heat-not-burn article, comprising:
- an aerosol-forming substrate comprising tobacco and a sulphide scavenger compound based on a transition metal,
- wherein an amount of a transition metal component of the sulphide scavenger compound in the aerosol-forming substrate is at least 0.05 percent by weight, based on a total dry weight of the aerosol-forming substrate.
An aerosol-generating system, comprising:
- an aerosol-generating device comprising a heating element;
- and
- a heat-not-burn article for the aerosol-generating device, the heat-not-burn article comprising:
- an aerosol-forming tobacco substrate comprising tobacco and a sulphide scavenger compound based on a transition metal, wherein an amount of a metal component of the sulphide scavenger compound in the aerosol-forming substrate is at least 0.05 percent by weight, based on a total dry weight of the aerosol-forming substrate.
An aerosol-forming substrate for a heat-not-burn article, the aerosol-forming substrate comprising tobacco and a sulphide scavenger compound based on a transition metal, wherein an amount of a transition metal component of the sulphide scavenger compound in the aerosol-forming substrate is at least 0.05 percent by weight, based on a total dry weight of the aerosol-forming substrate, and wherein in a heat-not-burn article comprising the aerosol-forming substrate, the sulphide scavenger compound in the aerosol-forming substrate provides a reduction of at least 50 percent by weight of hydrogen sulphide during a pre-heating test compared with an equivalent heat-not-burn article without the sulphide scavenger compound in the aerosol-forming substrate, and wherein in the pre-heating test a heating element configured to heat the aerosol-forming substrate in the heat-not-burn article is programmed to heat at 350 degrees Celsius for 30 seconds and then to switch off.
A method for the production of a heat-not-burn article, comprising the steps of:
- providing a tobacco particulate material;
- forming a slurry from the tobacco particulate material;
- incorporating a sulphide scavenger compound based on a transition metal into the slurry formed from the tobacco particulate material;
- forming a tobacco sheet from the slurry comprising the tobacco particulate material and the metal-based sulphide scavenger compound;
- forming the tobacco sheet into a plug to provide an aerosol-forming substrate;
- and
- combining the aerosol-forming substrate with one or more components to form a heat-not-burn article.
