A class of molecularly imprinted polymers that specifically recognizes and binds to nitrosamines members of which class are useful, for example, in analysis and separation of nitrosamines from biological fluids. Such molecularly imprinted polymers are also useful in methods of treating and manufacturing tobacco products and materials.

Aspects of the present disclosure relate to electrochemical reduction of tobacco-specific nitrosamines (TSNAs). According to certain methods described herein, a tobacco composition containing one or more TSNAs and nicotine is contacted with a solvent to form a tobacco mixture. In some embodiments, the tobacco mixture is introduced into an electrochemical device comprising an anode and a cathode. The tobacco mixture may, in some cases, form at least part of an initial electrolyte mixture that is in physical contact with at least a portion of the anode and at least a portion of the cathode. In some instances, an electrical potential is applied between the anode and the cathode, thereby reducing one or more TSNAs in the initial electrolyte mixture and producing a reduced electrolyte mixture. In certain cases, application of the electrical potential between the anode and the cathode does not cause non-TSNA components of the tobacco mixture (e.g., nicotine) to undergo electrochemical reduction or any other chemical reaction.

The subject matter relates to a stylized layer for a cigarette packet, which is developed to fit the packet. It fits the packet recess, enclosing all the rear part and part of the side of the packet, and is provided with a rear wall with a cutout and an internal compartment housing an infrared insert emitting signals in the long infrared. The long-infrared insert has substances that allow a reduction in the level of nicotine and of various other elements harmful to the user's health, found in cigarettes. The user can stylize the packet, since the layer is able to receive promotional messages and be decorated. It allows the control of the substances entering the body, making it possible for the user, to give up smoking. The longer the time of contact between the layer and the packet, the more the level of nicotine and substances in cigarettes will diminish.

There is provided a method of forming an aerosol-generating substrate, the method including providing a liquid nicotine source containing at least one tobacco-specific nitrosamine; mixing the liquid nicotine source with a solvent and at least one aerosol former to form an aerosol-generating substrate; and irradiating the aerosol-generating substrate with ultraviolet light to reduce an amount of the at least one tobacco-specific nitrosamine. Also provided is a method of forming an aerosol-generating substrate, the method including providing a tobacco slurry containing at least one tobacco-specific nitrosamine; irradiating the tobacco slurry with ultraviolet light to reduce an amount of the at least one tobacco-specific nitrosamine; and drying the tobacco slurry to form an aerosol-generating substrate.

This cartridge is provided with a flavor source housing which houses a flavor source, and a mesh body which is arranged on at least one end of the flavor source housing. The mesh body has multiple openings. Each of the openings has a polygonal shape with interior angles of less than or equal to 180°. As lengths that pass through the center of gravity of each opening, each opening has a minimum length that is shortest and a maximum length that is longest. The minimum length is less than the smallest size of the raw material pieces, and the maximum length is greater than the minimum length.

A baked item includes a tobacco and a microwave absorbing agent. The tobacco and the microwave absorbing agent are both capable of absorbing microwaves to generate heat, the microwave absorbing agent is made of a non-volatile solid material with a stable dielectric loss constant. The microwave absorbing agent is capable of stably absorbing microwaves to generate heat to heat the tobacco through thermal conduction. A method for preparing the baked item and a microwave heating method for the baked item include, the microwave absorbing agent is added into the tobacco, and the microwave absorbing agent can stably absorb microwaves to generate heat. In addition to absorbing microwaves to generate heat, the tobacco may be also heated by the microwave absorbing agent through thermal conduction, and temperature rising of the tobacco is more stable and uniform under a double heating mechanism of microwave radiation and thermal conduction.
