The present invention provides methodologies, including the utilization of genetically modified (GM) tobaccos, for the development and production of consumer acceptable PREPs encompassing the following: 1) production of low tar-to-nicotine ratio cigarettes, which allow smokers to obtain satisfying amounts of nicotine more efficiently than conventional cigarettes while reducing whole smoke deliveries; thereby reducing smoker “compensation” that exists with conventional low-yield cigarettes; 2) reduction of harmful tobacco-specific nitrosamines in tobacco products by genetic means and by extracting nicotine from tobacco and combining such with genetically modified reduced-nicotine tobacco; 3) production of improved expanded tobacco which utilizes genetically modified increased-nicotine tobacco; and 4) production of reconstituted tobacco which includes any combinations of the following: genetically modified increased-nicotine tobacco, genetically modified reduced-nicotine tobacco, tobacco leaf fractions, and freshly harvested freeze-dried tobacco.

The invention discloses a high-nicotine tobacco extract and application thereof, and belongs to the field of tobacco additives. The extract is rich in aroma components such as megastigmatrienone, damascone, pyrones and furanones in tobacco, can provide tobacco aroma and roasting aroma, further contains certain nicotine, can cater for physiological needs of consumers, and improves satisfaction. Content of macromolecular substances such as proteins, pectin and polysaccharides in the extract is extremely low, solubleness is good, the high-nicotine tobacco extract can be completely dissolved into MCT (medium chain triglyceride), and can be used for perfuming a filter tip. Besides, the high-nicotine tobacco extract is added into cut stems or reconstituted tobaccos, so that stimulus can be reduced, strength is improved, a blending rate, in a tobacco group, of the cut stems or reconstituted tobaccos is increased, and content of cigarette tar is reduced while fragrance is invigorated and impurities are covered.

The invention relates to a device for in vitro simulated dissolution and continuous online detection of nicotine in bagged and buccal tobacco products, which comprises: a chromogenic agent holding device (R1); an eluting agent holding device (R2); The first peristaltic pump (P1) downstream of the colorant storage device (R1) and connected to it through pipelines; the second peristaltic pump (P2) located downstream of the eluent storage device (R2) and connected in sequence through pipelines , a dissolution tank (A), a decolorization column (B), a reaction tank (R) and a spectrophotometer (D); wherein the reaction tank (R) is also located downstream of the first peristaltic pump (P1) and passed through the tube The road is connected to it, and the spectrophotometer (D) is connected to the data processing device (C). The invention also relates to a method for simulating dissolution of nicotine in vitro and continuous on-line detection in bagged and buccal tobacco products. The detection device and the detection method of the present invention can realize the continuous on-line detection of nicotine dissolution in vitro, and the operation is convenient and the detection is rapid.

The invention relates to an enzyme preparation using nicotine dehydrogenase as an auxiliary for tobacco processing, and a preparation and use method thereof, belonging to the enzyme preparation added before tobacco re-curing to improve the tobacco grade. In the present invention, the known nicotine dehydrogenase enzyme source is removed and refined, and EDTA complexing agent is used to remove metal ions in the enzyme solution, so that the enzyme in the concentrated stock solution does not show enzymatic activity, so as to facilitate the passivation of long-term storage. It exists in a stable form, and is concentrated and prepared by freeze-drying to become an active tobacco additive. When used, it is diluted with water to replace the original second leaf moisturizing water when the cigarette is redried, which can better degrade the amount of nicotine in the tobacco and improve the smoking of tobacco. safety.

The invention is a kind of tobacco with low content of nicotine. The specific preparation method is as follows: the traditional Chinese medicine is first prepared as a liquid medicine, and then the liquid medicine is evenly sprayed on the tobacco, mixed well, and then mixed with food ingredients to obtain the desired product. The shredded tobacco of the present invention is very low in nicotine, and the smoker has clear head and eyesight after smoking, less phlegm and good taste, and can prevent and treat nasal congestion, headache, chest tightness and shortness of breath, etc. The hazards of smokers.

The invention relates to tobacco wax compositions suitable for use in a vaporizer. The tobacco wax may comprise additional excipients including vapor agents, penetration agents, buffer agents, and theological agents. The composition contains nicotine. The tobacco wax composition leaves a minimum of residue in the vaporizer when used. In another aspect, the invention relates to a portion-sized container (“pod”) of a tobacco wax composition for administration to a mammal or person. The pod is intended tor use in a personal (or other) vaporizer.

The invention discloses a preparation method of a high-nicotine tobacco extract. The preparation method of the high-nicotine tobacco extract belongs to the field of tobacco additives, and mainly comprises three steps of raw material pretreatment, subcritical extraction and molecular distillation. A baking process is adopted for pretreating tobacco leaves, so that reducing sugar of tobacco and a nitrogen-containing compound are promoted to generate maillard reaction, substances such as pyrone and furanone are produced, the baking aroma is improved, the reducing sugar content is reduced, the suction offensive odor is reduced, meanwhile, combined-state nicotine in the tobacco leaves is converted into a free state, and the content of the free-state nicotine is improved. A weak polar solvent is adopted for subcritical extraction, so that the extraction rate of tobacco feature aroma substances and the free-state nicotine can be improved; and low-temperature molecular distillation is combined, so that low-boiling-point aroma substances and the nicotine can be effectively enriched, the damage on thermosensitive substances due to high temperature is avoided, and meanwhile, the content of macromolecular substances such as pectin and protein in an extract is reduced. The method is simple in preparation process, simple and convenient to operate, and suitable for industrial production and application.

The invention discloses a low-nicotine tobacco extract and a preparation method thereof. The preparation method comprises the following steps: firstly, preparing tobacco extract liquid with relatively low nicotine content by extracting through a ketone or ester solvent; secondly, removing a certain amount of nicotine by water washing; thirdly, concentrating for removing the solvent; finally, completely removing the nicotine through molecular distilling to obtain a tobacco extract spice which is very low in nicotine content and higher in fragrance quality. By adopting the preparation method, the treated tobacco extract can be added into cigarettes in a larger amount, the cigarette fragrance can be improved more remarkably, the fragrance and concentration are enhanced, the strength and irritation are not increased basically, and the cigarette quality is improved well.
