摘要： A smokeless tobacco product for insertion into the mouth of a user is provided herein. The smokeless tobacco product can be prepared by impregnating a tobacco-containing nonwoven fabric with a second tobacco material, e.g., using at least one alternating electric field. The obtained impregnated tobacco-containing fabric is subsequently bonded to form a composite, which can be further modified in order to obtain desired properties such as moisture content and flavor profile.

摘要： The invention relates to method of treating a material containing nicotine and at least one nitrosamine to reduce the quantity of nitrosamine therein and to methods of producing a tobacco extract with reduced nitrosamine content. The methods comprise contacting tobacco with a solvent to produce a liquid phase tobacco extract containing nitrosamines and treating the liquid phase tobacco extract to decompose the nitrosamines in the liquid phase. The liquid phase extract may then be treated to reduce nitrosamine decomposition products therein. The invention also relates to tobacco material produced using these methods and to tobacco products incorporating such tobacco material.

摘要： 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.

摘要： This invention relates to a method for preparing expanded tobacco stems, characterized in that the method contains steps as follows: purification, stem expansion, hypoxia heat retention (hypoxia heat retention refers to heating the expanded stems at hypoxia environment and maintaining the temperature), natural stacking, sorting, and packaging. An expanded tobacco stem product prepared according to this method has uniform size and color. Taste is modest and plain when it is combusted, which does not affect the original taste flavour. Expansion volume, the ratio of the expanded stems to the total stems, and quality are stable, which can be used as adsorption material. More important, expanded tobacco stems made from stems of different origin, texture and year according to this method have uniform odor component, which can not be acquired by other expansion technologies. This technology has met the requirement for product fabrication.

摘要： A smoking system is provided in which a replaceable cigarette containing tobacco flavor material is electrically heated by a set of electrical heater elements contained within a lighter to evolve tobacco flavors or other components in vapor or aerosol form for delivery to a smoker. The cigarette and lighter are adapted to provide air flow patterns through the smoking system such that air flows transversely into the cigarette. Such patterns improve aerosol and flavor delivery to the smoker and reduce the condensation of residual heater-region vapor/aerosol in the smoking system.

摘要： In order to effect expansion of a shredded material, said material is impregnated with an inert organic liquid, which is subsequently vaporized. The major portion of the impregnation agent is removed by separation. In order to eliminate the residual amount of impregnation agent still contained in the material, the material is fed by conveyor belt (31) into a microwave chamber (35). The microwave chamber (35) is provided with microwave energy under continuous control conditions. The vapors are siphoned off and fed into a regenerator for recovery of the impregnation agent. Conditioned, pressurized air is directed at the material in the microwave chamber (35) through discharge nozzles (38) to cause the material to whirl up and become fluidized. The pressurized air serves as a carrier gas for the residual impregnation agent that is to be removed and may simultaneously be used for conditioning the tobacco.

摘要： A method of marking a smoking-article exterior wrapping, particularly a cigarette wrapping, in which the wrapping, comprising a substance which causes or undergoes a permanent change of color under the action of the application or transmission of energy, is subjected to energy over an area of a conformation corresponding to the required marking, whereby a color change is caused over the area. The energy transmission may advantageously take the form of heat conduction. Alternatively, the energy transmission may take the form of electromagnetic or corpuscular radiation or irradiation.The wrapping and a heated former of conformation may be brought into contact with each other or may be maintained in contact with each other under pressure. The wrapping may already form part of a smoking article when wrapping is being subjected to energy transmission. The smoking article may in this case be rolled about the longitudinal axis thereof in contact with a former, which may mould an impression into wrapping. The method is advantageously performed on a filter-tip assembling machine.The wrapping may be tipping wrapping composed at least substantially wholly of cellulose fibres or comprise a major proportion of polypropylene fibres and a minor proportion of cellulose fibres.A smoking article according to the invention may comprise a wrapping bearing a marking which has been produced by wrapping having been subjected to energy transmission to effect a color change of said wrapping.
摘要翻译：一种标记吸烟制品外部包装，特别是香烟包装的方法，其中包括在施加或传递能量的作用下引起或经历颜色的永久变化的物质的包裹物经受能量超过与所需标记相对应的构图区域，由此在该区域上引起颜色变化。能量传输可以有利地采取热传导的形式。或者，能量传输可以采取电磁或微粒辐射或照射的形式。缠绕和加热的构象变形体可以彼此接触或在压力下彼此保持接触。当包装被承受能量传递时，包装可能已经形成了吸烟制品的一部分。在这种情况下，吸烟制品可以围绕其纵向轴线与前者相接触，这可能使印模变成包裹。该方法有利地在过滤嘴组装机上进行。包装可以是至少基本上完全由纤维素纤维构成的包装，或者包含主要部分的聚丙烯纤维和较小比例的纤维素纤维。根据本发明的吸烟制品可以包括带有标记的包装，所述标记已经通过包裹已经经过能量传递而产生，以实现所述包装的颜色变化。
