Description

Novel tobacco product with uniform nicotine release per puff and method for preparing nicotine regulator, thick paste and sheet thereof

[0001] This application claims priority to a Chinese patent application filed with the Patent Office of China on October 27, 2023, with application number 2023114095190 and invention name “Novel tobacco product with uniform nicotine release per puff and method for preparing its nicotine regulator, thick paste and thin sheet”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present invention relates to the technical field of cigarettes, in particular to the field of new tobacco and sheet preparation thereof. Background Art

[0003] Tobacco flakes were first introduced in the 1960s as a recombinant process to recycle waste from tobacco processing. However, with growing concern about the health benefits of cigarettes, tobacco flakes have taken on a more important role. Because their chemical composition and combustion properties are easier to manipulate than traditional tobacco leaves, they have been given the ability to reduce tar and reduce harm, becoming a functional carrier or a primary material for improving cigarette combustion and regulating the chemical composition of smoke. Today, with the rise of new tobacco products such as heated cigarettes, tobacco flakes are being used as the primary smoking material in heated cigarettes, further expanding their functionality. The main methods for manufacturing tobacco flakes include the slurry method, roller pressing, papermaking, and modified papermaking (dry method). Currently, 80% of heated cigarettes use slurry or roller pressing flakes as the smoking material. Both methods require mixing tobacco ash with a binder to create a slurry before producing the flakes. However, flakes produced using the traditional slurry method suffer from quality issues such as insufficient aroma, bland flavor, and poor puff-to-puff uniformity of nicotine release. Especially when used in the manufacture of heated cigarettes, the above-mentioned quality problems will be more prominent.

[0004] Several solutions have been reported in the prior art to address the issue of nicotine release. Chinese patent publication CN113115973A discloses a method for preparing reconstituted tobacco leaf sheets for heated cigarettes, comprising: preparing reconstituted tobacco slurry using a papermaking process; first, adding a 0.01%-0.15% by weight polyethylene oxide solution and a 0.01%-0.15% by weight guar gum solution to the reconstituted tobacco slurry; then, adding at least one of cactus juice and carambola vine juice to the reconstituted tobacco slurry; and finally, forming the reconstituted tobacco leaf sheets for heated cigarettes from the reconstituted tobacco slurry. This process, which discloses a papermaking process for thin sheets, can improve nicotine loading and release.

[0005] In summary, there are few reports on the controllable release of nicotine in tobacco tissues under the smoking mode of new tobacco products in the existing technology.

[0006] Summary of the Invention

[0007] To address the problem of difficulty in controlled release of nicotine from tobacco tissue during smoking of existing novel tobacco products (such as heated cigarettes) produced from thick pulp-processed sheets, the present invention provides a nicotine regulator that improves the puff-by-puff nicotine release uniformity of heated cigarette smoke, aiming to improve the controlled release of nicotine from tobacco tissue during the smoking phase of novel tobacco products.

[0008] The second object of the present invention is to provide a thick paste, a thin sheet and a novel tobacco product containing the nicotine regulator and a preparation method thereof, in order to improve the controllable and uniform release of nicotine in the novel tobacco product.

[0009] New tobacco is smoked using a heating method, with temperatures during the smoking phase mostly between 150°C and 300°C. Under this smoking mechanism, the controlled release of nicotine from tobacco tissue is difficult and the release uniformity is unsatisfactory. To address this issue, the present invention provides the following solutions:

[0010] A nicotine modulator for improving the puff-by-puff nicotine release uniformity of a novel tobacco product, comprising component A and component B, wherein component A is at least one of tannic acid, proline, caffeic acid, and pyruvic acid;

[0011] The component B is at least one of phosphoric acid and boric acid.

[0012] In response to the problems of nicotine being difficult to release and having unsatisfactory release uniformity due to the characteristics of the smoking mechanism of new tobacco products, the present invention innovatively studies and shows that the combination of components A and B can unexpectedly achieve synergy, adapt to the application requirements of new tobacco products, induce and adjust the release behavior of nicotine in tobacco tissues, and improve the puff-by-puff release uniformity of nicotine in tobacco tissues during the smoking phase.

[0013] In the present invention, the combined synergy of components A and B is the key to adapting to the use requirements of new tobacco products and improving the uniformity of nicotine release.

[0014] Preferably, component A is a complex of two or more of proline, caffeic acid, and pyruvic acid, and more preferably a complex of proline, caffeic acid, and pyruvic acid in a mass ratio of 1-2:1 to 2:1. Studies have also shown that the use of this preferred component A can achieve a more optimal synergistic effect with component B, further improving the nicotine release effect and uniformity of the novel tobacco product.

[0015] Preferably, ingredient B is phosphoric acid, or a phosphoric acid-boric acid complex, preferably a phosphoric acid-boric acid complex at a weight ratio of 1 to 3:1. Studies have also shown that the use of the preferred ingredient A can achieve a better synergistic effect with ingredient B, further improving the nicotine release effect and uniformity of the novel tobacco product.

[0016] In the present invention, the weight ratio of component A to component B is 1 to 3:1.

[0017] The present invention also provides a thick slurry for novel tobacco products with uniform nicotine release per puff, which comprises a slurry of viscose, cigarette ash and the nicotine regulator of the present invention.

[0018] In the present invention, thanks to the combination of the nicotine modulator components and the effect of the glue, the nicotine modulator can be encapsulated and grafted in the glue network and encapsulate and modify the surface of the tobacco tissue. This can unexpectedly achieve synergy and improve the puff-by-puff release uniformity of nicotine in the tobacco tissue during the smoking stage.

[0019] In the present invention, the viscose (adhesive) may be an adhesive solution comprising PEG, plant glue and defibrillated fibers;

[0020] In the present invention, the plant gum is at least one of sesbania gum, sesame gum, fennel gum, carrageenan, xanthan gum, guar gum, CMC, tamarind gum, sodium alginate, and microcrystalline cellulose;

[0021] Preferably, the plant gum is a composite of two or more of sesbania gum, flax gum, fennel gum, carrageenan, CMC, and pectin; more preferably, it is a composite of two or more of carob bean gum, microcrystalline cellulose, CMC, and pectin. The composite comprises 20 to 60 wt.% of each component, and the total amount of the components is 100 wt.%. Studies have shown that this preferred composite plant gum can further regulate nicotine release in conjunction with other components, synergistically improving the puff-by-puff uniformity of nicotine in tobacco tissue during the smoking phase of novel tobacco.

[0022] In the present invention, the fibrillated fiber can be an existing commercial product, or can be obtained based on a fibrillation method known in the industry. For example, the fibrillated fiber is a fiber obtained by fibrillating wood pulp fibers;

[0023] Preferably, the viscose further contains at least one solvent selected from water and an organic solvent;

[0024] Preferably, the organic solvent is a C1-C4 alcohol.

[0025] In the viscose of the present invention, the concentration of PEG is less than or equal to 30%, the concentration of plant gum is less than or equal to 10%, and the concentration of defibrillated fiber is less than or equal to 10%. Furthermore, in the viscose, the concentration of PEG is 1-20%, the concentration of plant gum is 1-10%, and the concentration of defibrillated fiber is 1-10%. Furthermore, the concentration of PEG is 1-10%, the concentration of plant gum is 1-5%, and the concentration of defibrillated fiber is 1-5%.

[0026] Preferably, the ash contains at least one of tobacco leaves (such as shredded tobacco), tobacco stems, puffed shredded tobacco, and puffed shredded stems;

[0027] Preferably, the cigarette ash is also allowed to contain at least one of tobacco stems, papermaking thin sheets, tea leaves, and plant fibers;

[0028] The thick paste of the present invention further comprises an atomizer, a flavor regulator, an auxiliary agent and other permitted ingredients.

[0029] The atomizer is at least one of ethylene glycol and glycerol. The amount of the additional ingredients can be adjusted as needed. For example, the atomizer content in the thick slurry is 5 to 20 wt.%.

[0030] Preferably, in the thick slurry, the weight ratio of soot to viscose is 1:3-10; the percentage of the nicotine regulator in the total weight of soot and viscose is 1-10 wt%.

[0031] The present invention also provides a method for preparing the thick slurry for heated cigarettes with uniform nicotine release per puff, which is obtained by uniformly mixing the various ingredients.

[0032] Preferably, the viscose and component A of the nicotine regulator are mixed in advance, then mixed with cigarette ash, and then mixed with component B of the nicotine regulator to obtain the thick paste;

[0033] Alternatively, the viscose and cigarette ash are mixed to obtain a basic thick paste, which is then mixed with a nicotine regulator to obtain the thick paste.

[0034] The present invention unexpectedly discovered that the thick slurry prepared by the mixing method can unexpectedly further modify the surface of tobacco tissue based on the physicochemical relationship between the components, compared to the thick slurry preparation process of pre-mixing the viscose and nicotine atomizer components. This can unexpectedly improve the uniformity of nicotine release in the tobacco tissue of the prepared novel tobacco product during the smoking stage.

[0035] The present invention also includes a novel tobacco product thick slurry sheet with uniform nicotine release per puff, which is obtained by slurrying and drying the thick slurry.

[0036] The present invention also provides a novel tobacco product with uniform nicotine release per puff, comprising the thick pulp sheet of the present invention;

[0037] Preferably, the novel tobacco product is a heated cigarette, and the heating section thereof comprises the thick pulp sheet.

[0038] The beneficial effects of the present invention include:

[0039] 1. The present invention provides a nicotine modulator for improving the puff-by-puff nicotine release uniformity of heated cigarettes. The combination of the aforementioned components can synergistically regulate the nicotine release behavior in heated cigarettes, thereby improving the nicotine release effect and puff-by-puff release uniformity in tobacco tissue during the smoking process of novel tobacco.

[0040] 2. In the present invention, component A is a complex of two or more of proline, caffeic acid, and pyruvic acid, and component B is phosphoric acid, or a complex of phosphoric acid and boric acid, which has a better combined synergistic effect, can better adapt to the application requirements of new tobacco products, and can better improve the nicotine release effect and uniformity in tobacco tissue during the smoking stage of new tobacco products.

[0041] 3. The present invention also provides a thick paste containing the aforementioned nicotine modifier. This thick paste, benefiting from the use of the aforementioned nicotine modifier, can effectively improve nicotine release. Furthermore, the plant gum can be a composite of two or more of carob bean gum, microcrystalline cellulose, CMC, and pectin. This can be combined with the nicotine modifier to surface-modify tobacco tissue, thereby further improving nicotine release from tobacco tissue during the puffing phase of the novel tobacco product. Furthermore, by combining the preparation method with the aforementioned control, the nicotine release of the prepared thick paste sheet can be further improved based on the physicochemical relationships between the components.

It is obvious that those skilled in the art can modify, adapt, and combine the methods and applications described herein to implement and apply the technology of the present invention without departing from the content, spirit, and scope of the present invention.

[0043] The raw materials and reagents used in Examples 1 to 6 and Comparative Examples 1 to 4 provided by the present invention can all be purchased from the market.

[0044] The present invention will be further described below in conjunction with the embodiments:

[0045] Example 1

[0046] Step 1: Preparation of Nicotine Modulator A

[0047] Weigh 0.5 kg of proline and caffeic acid respectively, add 5.0 kg of water, stir thoroughly, dissolve and set aside.

[0048] Step 2: PEG preparation

[0049] Weigh 0.2 kg each of PEG-400, PEG-2000, and PEG-6000, add 0.02 kg of tannic acid with 5.0 kg of water, heat to 80±5°C in a dedicated dissolving tank with insulation, fully dissolve, and set aside.

[0050] Step 3: Preparation of viscose (adhesive)

[0051] Place 1.5 kg of sucrose fiber in a hydraulic shredder, add 30 kg of water, and stir at 2000 rpm. After stirring for 60 minutes, add 0.2 kg of vegetable gum (carob bean gum) and 0.1 kg of carrageenan. Continue stirring for 30 minutes. Use the low-concentration adhesive to bring the fiber to the hydraulic shredder, using a geared stirring rod to thoroughly vortex and defibrate the fiberboard. Then, add 0.2 kg of vegetable gum (carob bean gum), 0.1 kg of CMC, the nicotine modifier A prepared in the first step, the PEG solution prepared in the second step, and 0.5 kg of flavor enhancer (adjust to taste; in this case, mint essence is used as an example). Continue stirring for 30 minutes, then transfer to a storage tank for later use.

[0052] Step 4: Preparation of soot composites

[0053] Tobacco leaves, tobacco stems and tea leaves in a weight ratio of 6:3:1 are dry-ground into 300-mesh ash for later use (ash).

[0054] Step 5: Thick slurry treatment

[0055] The materials prepared in steps 3 and 4 were transferred to a mixer at a weight ratio of 5:1. 0.6 kg of phosphoric acid (nicotine regulator B) was added. The agitator was started at 100 rpm and the slurry temperature was adjusted to (60 ± 5)°C. The mixture was stirred and held for 4 hours to mix.

[0056] Step 6: Thin slice preparation

[0057] After the fifth step of holding time has reached the process requirements, the thick slurry is spread, dried, and peeled to form thin sheets. The drying process adopts a two-stage process, with the maximum temperature not exceeding 90°C. The thickness of the thick slurry casting is controlled to be around 600mm.

[0058] Physical index testing of the finished slices prepared according to the above method showed that the thickness of the slices was 0.17 mm and the moisture content of the slices was 11.8%.

[0059] Referring to the traditional Canadian HCI deep puff pattern, the number of puffs (n) was set according to the heating time of the device. The heating device was designed to operate at a temperature of 220°C ± 5°C. Ten cigarettes were prepared for each heated cigarette sample. The n puffs of each cigarette were accumulated and captured on different filters. That is, the same number of puffs (a total of 10 puffs) of aerosol were captured on each filter. The standard deviation, relative standard deviation, and range of the data were calculated. The results are shown in Table 1.
