Description

Technical Field

[0001] The present invention belongs to the technical field of thick slurry method heated cigarette reconstituted tobacco, and specifically relates to a technology for stably releasing smoke puff by puff during the heating process of heated cigarette products, and in particular to a heated cigarette reconstituted tobacco by adding a sodium acetate composition and a preparation method thereof, which can effectively improve the stable release performance of thick slurry method heated cigarette reconstituted tobacco. Background Art

[0002] Heated cigarettes are a new type of tobacco product that releases nicotine and tobacco flavor by heating rather than burning tobacco. Heated cigarettes integrate a variety of technologies, such as lithium batteries, microprocessors, high-efficiency heating coils, etc., to heat tobacco below 500°C (generally in the range of 250°C-350°C) but not burn it. This method aims to maintain the original flavor of tobacco and release nicotine while avoiding the production of other harmful substances by tobacco combustion, thereby eliminating most of the harmful substances produced by tobacco combustion while maintaining the smoking experience.

[0003] Smoke-generating agent is an important substance that promotes the release of the original flavor and nicotine of heated cigarette tobacco. When the cigarette cartridge is heated, the smoke-generating agent acts as a promoter to help the smoke condense into smoke when passing through the reconstituted tobacco leaves in the condensation chamber, thereby producing aroma and nicotine, which enter the consumer's mouth after being filtered through the filter. During the smoking process, the stable release of aroma and nicotine in the heated cigarette smoke directly affects the power of the heated cigarette and the satisfaction of the consumer. In order to solve the problem of stable puff-by-puff release of heated cigarette smoke and improve the stability and satisfaction of smoking, it is necessary to prepare a heated cigarette reconstituted tobacco leaf to improve the stability of smoke release of heated cigarettes. Based on this, the present application was developed. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art, improve the stable release performance of heated cigarette smoke, and provide a heated cigarette reconstituted tobacco leaf with a sodium acetate composition added. The present invention uses sodium acetate as a pH buffer and a heat-stable matrix, which is melted at a high temperature to form a slow-release carrier, and the buffering capacity is enhanced by disodium hydrogen phosphate to maintain the pH stability of the system and prevent the decomposition of components. Sodium citrate chelates metal ions, reduces oxidation reactions, and assists in regulating humidity. When the smoke-generating agent is heated, an aerosol is generated to carry the release of components such as aroma and nicotine.

[0005] The present invention also provides a method for preparing the heated cigarette reconstituted tobacco leaves added with the sodium acetate composition.

[0006] To achieve the above object, the present invention adopts the following technical solution: A sodium acetate composition comprises the following components in parts by weight: 0.5 to 3 parts of sodium dihydrogen phosphate, 0.8 to 5.7 parts of sodium citrate, 0.8 to 4.6 parts of sodium acetate, and 10 to 30 parts of a smoke generating agent.

[0007] As a preferred embodiment, the sodium acetate composition comprises the following components in parts by weight: 0.5 to 2 parts of sodium dihydrogen phosphate, 1.0 to 3 parts of sodium citrate, 1.0 to 4.0 parts of sodium acetate, and 15 to 25 parts of smoke generating agent. Within this range, it can maintain the pH stability of the system, reduce oxidation reactions, melt at high temperatures to form a sustained-release carrier, generate an aerosol when heated, and carry the stable release of components such as aroma and nicotine.

[0008] More preferably, the sodium acetate composition comprises the following components in parts by weight: 0.8 to 1 part of sodium dihydrogen phosphate, 1.5 to 2.5 parts of sodium citrate, 2.0 to 3.5 parts of sodium acetate, and 18 to 22 parts of smoke generating agent.

[0009] Specifically, the smoke generating agent includes but is not limited to one or a mixture of any proportion of glycerol, propylene glycol, triethylene glycol, diethylene glycol and triethylene glycol.

[0010] Furthermore, as a preference, the smoke generating agent may be glycerol, or a mixture of glycerol and propylene glycol, etc.; more preferably, the mass ratio of glycerol to propylene glycol may be 7 to 9:2.

[0011] Furthermore, the pH of the sodium acetate composition may be 6.02 to 6.46.

[0012] The present invention provides a method for preparing the sodium acetate composition, which comprises the following steps: 1) Weigh each component according to the designed ratio, heat the smoke agent to 50 ~ 60 ℃, and add disodium hydrogen phosphate, sodium citrate and sodium acetate while stirring; 2) Adjust the pH to 6.02-6.46 with citric acid to obtain a sodium acetate composition.

[0013] The present invention also provides the use of the sodium acetate composition as an additive in the preparation of reconstituted tobacco leaves for heating cigarettes.

[0014] The present invention also provides a heated cigarette reconstituted tobacco leaf, to which the sodium acetate composition is added.

[0015] The present invention also provides a method for preparing heated cigarette reconstituted tobacco leaves by adding a sodium acetate composition, which comprises the following steps: Step 1, dissociating 2-5% of the mass of softwood paddle relative to the tobacco powder to obtain softwood fiber; Step 2, adding the dissociated softwood fibers into water and mixing them to obtain a fiber mixed solution with a solid content of 0.6-1.0%; Step 3, adding 2-4% of adhesive relative to the mass of the tobacco powder to the fiber mixture, stirring and dissolving; Step 4, adding 12 to 44% of the sodium acetate composition relative to the mass of the tobacco powder to the mixed solution and stirring evenly; Step 5, adding tobacco powder to the mixed solution, mixing well, obtaining thick slurry method heated cigarette reconstituted tobacco slurry, and adopting a conventional thick slurry method heated cigarette reconstituted tobacco production line to obtain heated cigarette reconstituted tobacco.

[0016] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows: The invention uses sodium acetate as a pH buffer and a heat-stable matrix, which is melted at high temperature to form a slow-release carrier, and disodium hydrogen phosphate is used to enhance the buffering capacity, maintain the pH stability of the system, and prevent the decomposition of components. Sodium citrate chelates metal ions, reduces oxidation reactions, and assists in regulating humidity. When the smoke-generating agent is heated, an aerosol is generated to carry the release of components such as aroma and nicotine.

[0017] By adding the sodium acetate composition of the present invention to the reconstituted tobacco leaves of the heated cigarette, during the smoking process, the aroma and nicotine in the smoke of the heated cigarette can be stably released puff by puff, which effectively improves the smoke release stability of the heated cigarette, enhances the power of the heated cigarette and the smoking satisfaction of consumers.

[0018] The sodium acetate composition provided by the present invention significantly improves the stable release of smoke from thick slurry heated cigarettes, and through the synergistic effect of various components, achieves the continuous and stable release of smoke from thick slurry heated cigarettes, thereby improving the utilization of heated cigarettes. At the same time, the stable release of smoke can significantly improve the smoking quality and the smoking satisfaction of heated cigarettes, thus providing an effective improvement method for the stable release of smoke from thick slurry heated cigarettes.
