Description

Technical Field

[0001] (Cross-reference) This application claims priority based on a Chinese patent application filed with the China National Intellectual Property Administration on October 27, 2023, with an application number of 2023114095190 and an invention title of "Novel Tobacco Products with Uniform Nicotine Release per Dose, Nicotine Regulators, Concentrated Slurries, and Methods for Manufacturing Sheets", and the entire content thereof is incorporated herein by reference.

[0002] The present invention relates to the field of cigarettes, particularly to the field of manufacturing novel tobacco and its sheets.

Background Art

[0003] Tobacco sheets are a reprocessing process adopted in the 1960s to solve the problem of recycling waste generated during the tobacco processing. As public concern about the health risks of cigarettes has grown, tobacco sheets have come to play an important role. Compared to conventional tobacco leaves, tobacco sheets are easier to adjust in terms of chemical composition and combustion performance, and have been given the function of reducing tar content and mitigating health damage. They are used as functional carriers or as main materials to improve combustion and adjust the chemical composition of smoke. In recent years, with the rapid spread of new types of tobacco such as heated tobacco products, tobacco sheets have been used as the main smoke-generating material in the new tobacco field, and their functionality has become more widely utilized. The main methods for manufacturing tobacco sheets include the concentrated slurry method, the rolling method, the papermaking method, and the improved papermaking method (dry papermaking method). Currently, 80% of the smoke-generating materials in new tobacco products in the new tobacco field use sheets made by the concentrated slurry method or the rolling method. When manufacturing sheets using the above two methods, it is necessary to mix tobacco scraps and a binder before preparing the concentrated slurry. However, sheets manufactured using conventional concentrated slurry or rolling methods have quality issues such as insufficient tobacco aroma, a weak fragrance, and poor uniformity of nicotine release with each puff. These quality problems are particularly severe when used in the manufacture of heated tobacco products.

[0004] Conventional technologies have reported several solutions to the problem of nicotine release. For example, Chinese patent document No. CN113115973A discloses a method for producing a reconstituted tobacco sheet for heated tobacco products, which includes preparing a reconstituted tobacco leaf slurry by papermaking, adding a polyethylene oxide solution and a guar gum solution at a mass percentage of 0.01% to 0.15% to the reconstituted tobacco leaf slurry, adding at least one of a cactus extract and a star fruit stem extract to the reconstituted tobacco leaf slurry, and processing the reconstituted tobacco leaf slurry into a reconstituted tobacco sheet for heated tobacco products. This process discloses a papermaking process for producing a sheet that can improve the amount of nicotine loaded and released.

[0005] Based on the above, there have been few relevant reports regarding the controllable release of nicotine in tobacco tissue for the inhalation mode of new tobacco products using conventional technologies. [Overview of the Initiative]

[0006] Conventional tobacco products (such as heated tobacco products) that use a concentrated slurry method to produce sheets have the problem of difficulty in controlling the release of nicotine in the tobacco tissue during inhalation. To address this problem, the present invention aims to provide a nicotine modifier that improves the uniformity of nicotine release from the smoke of heated tobacco products with each puff, thereby improving the controllable release of nicotine in the tobacco tissue during the inhalation phase of the new type of tobacco product.

[0007] A second object of the present invention is to provide a concentrated slurry containing the nicotine modifier, a tobacco sheet, a new tobacco product, and a method for manufacturing the same, in order to improve the controllable uniformity of nicotine release in the new tobacco product.

[0008] In the inhalation mechanism of new cigarettes, where the temperature during the inhalation stage is generally 150-300°C, it is difficult to control the release of nicotine from the tobacco tissue, and the uniformity of release is not ideal. In view of this problem, the present invention provides the following solution.

[0009] A nicotine modifier that improves the uniformity of nicotine release with each puff of a new type of tobacco product, comprising component A, which is at least one of tannic acid, proline, caffeic acid, and pyruvic acid, and component B, which is at least one of phosphoric acid and boric acid.

[0010] In light of the problems that nicotine is not easily released and the release uniformity is not ideal due to the characteristics of the inhalation mechanism of the new tobacco product, the inventors have conducted innovative research and found that when component A and component B are used in combination, an unexpected synergistic effect is obtained, which can be adapted to the user needs of the new tobacco product, can induce and adjust the nicotine release behavior in the tobacco tissue, and can improve the uniformity of nicotine release in the tobacco tissue with each puff during the inhalation stage.

[0011] In this invention, the combined and synergistic use of component A and component B is key to adapting to the user needs of new tobacco products and improving their nicotine release uniformity.

[0012] Preferably, component A is a complex of two or more of proline, caffeic acid, and pyruvic acid, and more preferably a complex acid of proline, caffeic acid, and pyruvic acid with a mass ratio of 1 to 2:1 to 2:1. Furthermore, as a result of further research, it has been found that using the above-mentioned preferred component A yields a synergistic effect that is more effectively adapted with component B, further improving the nicotine release effect and uniformity of the new tobacco product.

[0013] Preferably, component B is phosphoric acid or a phosphoric acid-boric acid complex, and preferably a phosphoric acid-boric acid complex with a weight ratio of 1 to 3:1. Furthermore, as a result of further research, it has been found that using the preferred component A as described above yields a synergistic effect that is more effectively adapted with component B, further improving the nicotine release effect and uniformity of the new tobacco product.

[0014] In this invention, the weight ratio of component A to component B is 1 to 3:1.

[0015] The present invention further provides a concentrated slurry for a new type of tobacco product having uniform nicotine release with each puff, comprising a binder, tobacco scraps, and a slurry of the nicotine adjusting agent described in the present invention.

[0016] In this invention, by combining the combined use of nicotine modifier components with the action of a binder, it is possible to encapsulate and graft them within the gum network, as well as encapsulate and modify the surface of the tobacco tissue. This results in unexpected synergistic effects, improving the uniformity of nicotine release from the tobacco tissue with each puff during the inhalation phase.

[0017] In the present invention, the binder (adhesive) may be an adhesive solution containing PEG, plant gum, and defibrated fibers.

[0018] In the present invention, the plant gum is at least one of cesibania gum, flaxseed gum, fenugreek gum, carrageenan, xanthan gum, guar gum, CMC, tamarind gum, sodium alginate, and microcrystalline cellulose.

[0019] Preferably, the plant gum is a complex of two or more components selected from cesivania gum, flaxseed gum, fenugreek gum, carrageenan, CMC, and pectin, and more preferably, a complex of two or more components selected from locust bean gum, microcrystalline cellulose, CMC, and pectin. The complex contains 20-60 wt% of a single component and 100 wt% of the total components. Through further research, it has been found that using the preferred complex plant gum, in combination with other components, helps to control the nicotine release behavior and further synergistically improves the uniformity of nicotine release in the tobacco tissue during the inhalation phase of the novel tobacco.

[0020] In the present invention, the defibrated fiber may be an existing commercial product or may be obtained by a defibration method known in the industry. For example, the defibrated fiber may be a fiber obtained by defibrating wood pulp fibers.

[0021] Preferably, the binder further contains at least one solvent selected from water and organic solvents.

[0022] Preferably, the organic solvent is an alcohol having 1 to 4 carbon atoms.

[0023] The binder described in the present invention has a PEG concentration of 30% or less, a plant gum concentration of 10% or less, and a defibration fiber concentration of 10% or less. More preferably, the binder has a PEG concentration of 1-20%, a plant gum concentration of 1-10%, and a defibration fiber concentration of 1-10%. Even more preferably, the PEG concentration is 1-10%, the plant gum concentration is 1-5%, and the defibration fiber concentration is 1-5%.

[0024] Preferably, the tobacco scraps include at least one of the following: tobacco pulp (such as shag), tobacco veins, expanded tobacco pulp shag, and expanded tobacco vein shag.

[0025] Preferably, the tobacco waste may further contain at least one of tobacco leaf vein fragments, sheet filaments by the papermaking method, tea leaves, and plant fibers.

[0026] The concentrated slurry described in the present invention may further contain acceptable additional components such as atomizing agents, flavor modifiers, and adjuvants.

[0027] The atomizing agent is at least one of ethylene glycol and propylene glycol. Further, the dosage of the additional components can be adjusted as needed. For example, in the concentrated slurry, the content of the atomizing agent is 5-20 wt%.

[0028] Preferably, in the concentrated slurry, the weight ratio of tobacco waste to binder is 1:3-10, and the nicotine regulator is 1-10 wt% based on the total amount of tobacco waste and binder.

[0029] According to the present invention, there is further provided a method for manufacturing a concentrated slurry for a novel tobacco product having uniform nicotine release per puff. In this manufacturing method, each component is uniformly mixed to obtain a concentrated slurry. Preferably, component A of the binder and the nicotine regulator is pre-mixed and then mixed with tobacco waste, and then mixed with component B of the nicotine regulator to obtain the concentrated slurry. Alternatively, the binder and tobacco waste are mixed to obtain a basic concentrated slurry, and then mixed with the nicotine regulator to obtain the concentrated slurry.

[0030] As a result of repeated research by the present inventors, compared with a method for preparing a concentrated slurry in which the binder and the nicotine atomizing agent components are pre-mixed together, when the concentrated slurry prepared by the above mixing method is used, surprisingly, the surface of the tobacco tissue can be further modified based on the physicochemical relationship between the components, and thereby, the uniformity of nicotine release in the tobacco tissue at the suction stage of the novel tobacco product prepared can be surprisingly improved.

[0031] According to the present invention, a sheet obtained by pulping and drying the aforementioned concentrated slurry is further provided, which has uniform nicotine release with each puff and is a new type of tobacco product sheet produced by a concentrated slurry method.

[0032] According to the present invention, a new type of tobacco product is provided that includes the concentrated slurry sheet described in the present invention and has uniform nicotine release with each puff. Preferably, the new tobacco product is a heated roll-up tobacco product, and its heating section includes the concentrated slurry sheet. [Effects of the Invention]

[0033] The beneficial effects of this invention are as follows:

[0034] I. The present invention provides a nicotine modifier that improves the uniformity of nicotine release with each puff of heated tobacco products. By using the above-mentioned components in combination, the nicotine release behavior from heated tobacco products can be synergistically adjusted, and the nicotine release effect in the tobacco tissue during the smoking process of the new type of tobacco product and the uniformity of release with each puff can be improved.

[0035] II. In the present invention, by making component A a complex of two or more of proline, caffeic acid, and pyruvic acid, and component B a phosphoric acid or a phosphoric acid-boric acid complex, a superior synergistic effect can be obtained, which can be more effectively adapted to the application requirements of new tobacco products, and the nicotine release effect and uniformity in the tobacco tissue during the inhalation stage of new tobacco products can be more effectively improved.

[0036] III. The present invention further provides a concentrated slurry containing the nicotine modifier. Applying the nicotine modifier can more effectively improve the nicotine release effect. In addition, by using a complex of two or more plant gums from locust bean gum, microcrystalline cellulose, CMC, and pectin, the surface of the tobacco tissue can be modified in combination with the nicotine modifier, thus helping to further improve the nicotine release effect in the tobacco tissue during the inhalation stage of the new tobacco product. Furthermore, by using and controlling the manufacturing method, the nicotine release effect of the prepared concentrated slurry sheet can be further improved based on the physicochemical relationships between the components.

[0038] The raw materials and reagents used in Examples 1 to 6 and Comparative Examples 1 to 4 according to the present invention may all be commercially available products.

[0039] The present invention will be further described below with reference to examples. [Examples]

[0040] Step 1: Preparation of Nicotine Adjuster A 0.5 kg each of proline and caffeic acid were weighed out, 5.0 kg of water was added, and the mixture was thoroughly stirred to dissolve them, preparing them for subsequent use.

[0041] Step 2: Preparation of PEG 0.2 kg each of PEG-400, PEG-2000, and PEG-6000 were weighed out, and 0.02 kg of tannic acid was added to 5.0 kg of water. The mixture was thoroughly dissolved in a dedicated insulated dissolution tank under conditions of heating at 80 ± 5°C, and prepared for subsequent use.

[0042] Step 3: Preparation of the binder 1.5 kg of sucrose fiber was placed in a hydraulic paper shredder, 30.0 kg of water was added, and the mixture was stirred at a speed of 2000 rpm / min for 60 minutes. Then, 0.2 kg of plant gum (locust bean gum) and 0.1 kg of carrageenan were added, and the mixture was stirred for another 30 minutes. Next, the fibers were fed into the hydraulic paper shredder using a low-concentration binder and thoroughly swirled with a geared stirring rod to completely defibrate the fiberboard. Then, 0.2 kg of plant gum (locust bean gum), 0.1 kg of CMC, nicotine modifier A prepared in step 1, PEG solution prepared in step 2, and 0.5 kg of flavor enhancer (adjustable according to preference; in this example, mint essence was used) were added, and the mixture was stirred for another 30 minutes. Finally, the mixture was transferred to a storage tank and prepared for subsequent use.

[0043] Step 4: Preparation of tobacco waste composite material Tobacco leaf pulp, tobacco leaf veins, and tea leaves were dry-ground in a weight ratio of 6:3:1 to produce a 300-mesh product (tobacco scraps), which was prepared for subsequent use.

[0044] Step 5: Processing of the thick slurry The materials prepared in steps 3 and 4 above were placed in a mixer in a weight ratio of 5:1, 0.6 kg of phosphoric acid (nicotine modifier B) was added, the stirrer was turned on, the rotation speed was controlled to 100 rpm / min, the temperature of the concentrated slurry was adjusted to (60±5)°C, and the mixture was mixed for 4 hours while stirring and maintaining the temperature.

[0045] Step 6: Preparing the tobacco sheet After the heat retention time in Step 5 reached the process requirements, the concentrated slurry was pulped, heat-dried, and peeled to form a sheet. The heat-drying process was divided into two stages, with the maximum temperature kept below 90°C. The casting thickness of the concentrated slurry was controlled to approximately 600 mm.

[0046] Physical indicators were detected from the finishing sheet prepared using the above method, revealing that the sheet thickness was 0.17 mm and the moisture content of the sheet was 11.8%.

[0047] Referring to the Canadian depth inhalation mode (HCI) of conventional rolled cigarettes, the number of inhalations (n) was set according to the heating time of the device, and the operating temperature of the heating device was set to 220°C ± 5°C. Ten cigarettes were prepared for each sample of heated rolled cigarettes, and the n inhalations from each cigarette were collected and captured in different filters. In other words, the same number of inhalations (10 in total) of aerosol were captured in each filter, and the standard deviation, relative standard deviation, and range of the data were calculated. The results are shown in Table 1 below.

[0048] (Comparative Example 1) Comparative Example 1 differs from Example 1 only in that Step 1 is omitted, and accordingly, component A of the nicotine regulator is not added in Step 3, and component B (phosphate) of the nicotine regulator is not added in Step 5.

[0049] [Table 1] [Examples]

[0050] Example 2 differs from Example 1 only in that the components of nicotine modifier A in Step 1 are changed, and the total weight of nicotine modifier A is the same as in Example 1. The experimental groups are as follows:

[0067] [Table 2]

[0068] Tables 1 and 2 clearly show that using a nicotine regulator having the composition of the present invention unexpectedly yielded a synergistic effect and improved the uniformity of nicotine release. Furthermore, Examples 1 and 2 revealed that using a combination of proline, caffeic acid, and pyruvate as nicotine regulator component A unexpectedly resulted in a further synergistic improvement in the uniformity of nicotine release.

[0069] Furthermore, Examples 1 and 4 revealed that using a combination of phosphoric acid and boric acid further synergistically improved the uniformity of nicotine release with each puff. A comparison between Example 1 and Example 3 also revealed that using a combination of microcrystalline cellulose, locust bean gum, and pectin unexpectedly synergistically improved nicotine release. Moreover, a comparison between Example 1 and Example 5 revealed that when preparing a concentrated slurry, pre-mixing component A into the adhesive, then mixing it with tobacco scraps, and finally mixing it with component B unexpectedly further improved the synergistic effect of the components, and improved the nicotine regulation effect to some extent. [Examples]

[0070] Step 1: Binder preparation 1.1 Preparation of PEG: 2 kg each of PEG-400, PEG-2000, and PEG-6000 were weighed out, and 0.2 kg of tannic acid was added to 50 kg of water.

Next, the fibers were fed into the hydraulic paper shredder using a low-concentration binder and thoroughly stirred with a geared stirring rod to completely defibrate the fiberboard. Then, 2 kg of plant gum (same as in Example 4B), 1 kg of CMC, the PEG solution prepared in step 1.1, and 5 kg of a flavor enhancer (e.g., mint essence) were added, and the mixture was stirred for 30 minutes. After that, the mixture was transferred to a storage tank and prepared for subsequent use.

[0072] Step 2: Preparation of tobacco scraps Tobacco leaf pulp, tobacco leaf veins, and tea leaves were dry-ground in a weight ratio of 6:3:1 and then ground to a 300-mesh consistency (tobacco waste) for subsequent use.

[0073] Step 3: Preparation of initial concentrated slurry The prepared binder and tobacco scraps were mixed in a weight ratio of 5:1 to form a concentrated base slurry.

[0074] Step 4: A nicotine modifier was added to the basic concentrated slurry (component A consisted of proline, caffeic acid, and pyruvic acid in a weight ratio of 1:1:1, and component B consisted of boric acid and phosphoric acid in a weight ratio of 1:1, with a weight ratio of 2:1 between component A and component B, and the amount of nicotine modifier used was 3 wt% of the total amount of the basic concentrated slurry), the stirrer was turned on and the rotation speed was controlled to 100 rpm / min, the temperature of the concentrated slurry was adjusted to (60±5)°C, and the mixture was stirred and kept warm for 4 hours to obtain a modified concentrated slurry.

[0075] Step 5: Preparing the tobacco sheet After the heat retention time in Step 4 reached the process requirement, the modified concentrated slurry was pulped, heat-dried, and peeled to form a sheet. The heat-drying process was divided into two stages, with the maximum temperature kept below 90°C. The casting thickness of the concentrated slurry was set to approximately 600 mm.

[0076] Following the method in Example 1, the standard deviation, relative standard deviation, and range of nicotine data for each inhalation were determined. The results are shown in Table 3 below.

[0077] [Table 3]

[0078] As described above, in the process of the present invention, an unexpected synergistic effect was obtained by using the components of the nicotine adjusting agent in combination, and the uniformity of nicotine release in the concentrated slurry sheet was greatly improved.
