Description

[Technical Field]

[0001] (cross reference) This application claims priority from a Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on October 19, 2023, bearing application number 202311357207.X and entitled "New type of tobacco with improved sensory evaluation quality and its heated section, and method for manufacturing sheets by thick slurry method," the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to the field of new materials for new tobacco products, and in particular to the technical field of designing and producing sheets for new tobacco products by the thick slurry method. [Background technology]

[0003] Tobacco sheet was reinvented in the 1960s to solve the problem of recycling waste generated during tobacco processing. As public concern about the health risks of cigarette smoking increased, tobacco sheet has come to play an important role. Because tobacco sheet's chemical composition and combustion performance can be more easily tuned than traditional tobacco leaves, it has been given the ability to reduce tar content and reduce health hazards. It is used as a functional carrier or as a primary material for improving combustion conditions and adjusting the chemical composition of smoke. With the rapid spread of heated cigarettes (new tobacco products) in recent years, tobacco sheet has become the primary smoke-producing material in new tobacco products, and its functionality has become more widely utilized. The main manufacturing methods for tobacco sheet include the slurry method, rolling method, papermaking method, and improved papermaking method (dry papermaking). Currently, 80% of the smoke-producing material in new tobacco products in the new tobacco product category is made using tobacco sheet produced by the slurry or rolling method. To manufacture tobacco sheet using these two methods, a thick slurry must be prepared by mixing tobacco waste with a binder before forming the sheet. However, tobacco sheets manufactured using the conventional slurry method or rolling method have quality problems, such as an insufficient tobacco aroma, a weak aroma, poor aroma quality, and a somewhat strong binder smell. These quality problems become particularly pronounced when used to manufacture new types of tobacco (e.g., heat-not-burn cigarettes).

[0004] Prior art has reported methods for adding flavors and fragrances to improve the evaluated taste of tobacco sheets. For example, Chinese patent document No. CN113508918A discloses a method for producing a long-lasting multi-flavor heated tobacco sheet, which involves adding a mixture of a polymeric flavor precursor, a thermally conductive binder, a thermally conductive colorant, and tobacco powder to a slurry containing wood pulp fiber, an atomizing agent, and water, controlling the stirring speed of the slurry, increasing the stirring speed and temperature of the concentrated slurry, selecting an appropriate coating flat and coating, and using freeze-drying technology to obtain a new type of tobacco sheet that is homogeneous, smooth, fine-grained, and easy to peel. Although this technology can achieve good technical effects, it suffers from problems such as an insufficient tobacco aroma, a weak aroma, a lower-quality aroma, a somewhat strong binder odor, and unsatisfactory taste in test smoking evaluations. Summary of the Invention

[0005] Conventional sheets made using the thick slurry method for new type tobacco (heat-not-burn tobacco) have had problems such as insufficient tobacco aroma, a weak aroma, poor aroma quality, a somewhat strong binder smell, and unsatisfactory taste in test smoking evaluations. In response to these problems, the first object of the present invention is to provide a method for improving the sensory evaluation quality of sheets made using the thick slurry method for new type tobacco (heat-not-burn tobacco), and to improve the taste of sheets made using the thick slurry method for new type tobacco (heat-not-burn tobacco) in test smoking evaluations.

[0006] A second object of the present invention is to provide a sheet for a new type of tobacco (heat-not-burn tobacco) produced by the concentrated slurry method using the above production method, and its application to a new type of tobacco (heat-not-burn tobacco).

[0007] A third object of the present invention is to provide a new type of tobacco (heat-not-burn tobacco) containing a sheet produced by the thick slurry method.

[0008] According to the present invention, there is provided a composition comprising a binder, a thickened slurry of tobacco shreds, and an additive, the composition comprising: The additives include additive A, additive B, and additive C, The additive A is at least one of ammonium dihydrogen phosphate, ammonium phosphate, and diammonium hydrogen phosphate, The additive B is a compound represented by the following formula (1): [ka] (wherein R is H, a C1-C6 alkyl group, a C1-C6 alkyl group having a substituent, or a heterocycle, and the substituent is at least one of a hydroxyl group, a thiol group, an aryl group, a carboxyl group, an amide group, a heterocycle group, and an amino group), A composition is provided wherein said additive C is a monosaccharide.

[0014] Preferably, additional vegetable fiber may be further added to the thickened slurry.

[0015] According to one aspect of the present invention, there is provided the use of the composition in improving the sensory evaluation quality of sheets produced by a new type of concentrated tobacco slurry method.

[0016] The method for improving the sensory evaluation quality of a sheet by the new type of thickened tobacco slurry method includes obtaining a thickened slurry containing a binder and tobacco waste, adding an additive to the thickened slurry and adjusting the pH of the slurry system to 3 to 6, then reacting the thickened slurry with stirring at a temperature of 50 to 95°C and under low pressure (negative pressure) conditions to obtain a modified thickened slurry, and pulping and drying the modified thickened slurry to obtain a sheet by the new type of thickened tobacco slurry method; The additives include additive A, additive B, and additive C, The additive A is at least one of ammonium dihydrogen phosphate, ammonium phosphate, and diammonium hydrogen phosphate, The additive B is a compound represented by the following formula (1): [ka] (wherein R is H, a C1-C6 alkyl group, a C1-C6 alkyl group having a substituent, or a heterocycle, and the substituent is at least one of a hydroxyl group, a thiol group, an aryl group, a carboxyl group, an amide group, a heterocycle group, and an amino group), The additive C is a monosaccharide.

[0017] In the present invention, additives including additives A, B, and C are added to a concentrated slurry, and the low-pressure stirring and temperature are controlled in conjunction with each other, thereby contributing to the exertion of a chemical synergistic effect of the additives, the improvement of flavor components, the reduction of unpleasant flavors, and the improvement of the taste in tasting evaluations.

[0018] In the present invention, the ingredients and contents in the concentrated slurry may be conventional or may be obtained by known means.

[0019] For example, the binder is at least one of vegetable gum, starch derivative, CMC, and sodium alginate, where the vegetable gum is at least one of xanthan gum, tamarind gum, carrageenan, guar gum, and konjac gum, and the starch derivative is at least one of modified starch, oxidized starch, and etherified starch.

[0020] In the present invention, the tobacco waste includes tobacco raw materials and may further include at least one of tobacco mesophyll (e.g., shag), leaf vein scraps, sheet filaments from papermaking, tea leaves, plant roots, plant stems, plant leaves, plant flowers, and plant fruits.

[0021] For example, an atomizing agent may be further added to the thick slurry, and the atomizing agent may be at least one of ethylene glycol and glycerol.

[0022] For example, additional vegetable fiber may be added to the thickened slurry.

[0023] Other ingredients that are recognized as additives in the industry may be added to the thickened slurry, and the content of the ingredients in the thickened slurry may be appropriately controlled based on known principles.

[0024] In the present invention, the coordinated control of the additive components, the low-pressure stirring process, and the temperature is the key to synergistically improving the taste of tobacco samples evaluated using the slurry method.

[0025] In the present invention, the additive A is ammonium dihydrogen phosphate. As a result of extensive research, the present inventors have found that when ammonium dihydrogen phosphate is used as additive A, it is possible to further improve the taste of the produced tobacco sheet in a smoking test evaluation by combining it with additives B and C and further carrying out an alcoholization treatment.

[0026] In the present invention, in formula (1), the heterocycle is, for example, a saturated ring or an aromatic ring, and the heteroatom therein is, for example, O or N, preferably N. The heterocycle is also, for example, a tetrahydropyrrole ring, an indole ring, pyrrole, imidazole, etc.

[0027] In the present invention, the additive B is a compound in which R is a heterocycle, and includes at least one of the following formulae (1-A) to (1-D). [ka]

[0028] According to the research results of the present invention, when additive B represented by formula (1-A) to formula (1-D) is used in combination with additive A and additive C, and further subjected to alcoholization treatment, the taste of the produced tobacco sheet can be further improved in the smoking test evaluation.

[0029] Preferably, additive B is a mixture of formula (1-A) and formula (1-C) in a weight ratio of 1:0.5 to 2. According to the research results of the present invention, it has been surprisingly found that the use of this preferred additive B can further improve the release effect of the target aroma substance and further improve the inhalation effect.

[0030] In the present invention, the monosaccharide is at least one of arabinose, ribose, xylose, lyxose, glucose, mannose, fructose, and galactose, and is preferably a mixture of ribose and glucose. The preferred monosaccharide can be further combined with the ingredients and process of the present invention to produce a synergistic effect, which can further improve the content of target aroma substances and further improve the taste in taste evaluation.

[0031] In the present invention, the weight ratio of additive A to additive B to additive C in the additives is 1:0.5-10:0.5-10, and may further be 1:1-2:1-10.

[0032] In the present invention, the weight ratio of the additive to the concentrated slurry is 0.3:1 or less, preferably 0.1 to 0.2:1.

[0033] In the present invention, after the additives are added, the pH of the slurry system is adjusted using a pH adjuster.

[0034] The pH adjuster may be a typical acid or alkali, for example, the acid may be phosphoric acid, and the alkali may be sodium hydroxide, potassium hydroxide, etc.

[0035] In the present invention, the pH of the concentrated slurry is adjusted to 3 to 5 using the pH adjuster.

[0036] In the present invention, when a concentrated slurry to which additives have been added and pH adjusted is reacted under low pressure conditions, the synergistic effect of the components is advantageous, and the taste of the produced tobacco sheet can be further improved in the smoking test evaluation.

[0037] Preferably, the low pressure is less than 0.1 MPa, preferably 0.001 to 0.05 MPa.

[0038] In the present invention, the low-pressure stirring process comprises a first-stage incubation process at a temperature T1 in the range of 55-65° C., and a second-stage incubation process at a temperature T2 in the range of 75-85° C. Research results of the present invention show that by further combining the synergistic additives with the two-stage gradient low-pressure stirring process, the chemical synergy between the components can be further improved, and the taste of the tobacco sheet can be further improved in the smoking evaluation.

[0039] In the present invention, low-pressure stirring is carried out for 4 to 30 hours, preferably 4 to 24 hours. When the preferred two-stage low-pressure stirring process is adopted, the first-stage low-pressure stirring process is preferably carried out for 2 to 15 hours, more preferably 2 to 4 hours. The second-stage low-pressure stirring process is preferably carried out for 2 to 15 hours, more preferably 2 to 4 hours.

[0040] The present invention further provides a sheet for a new type of tobacco (heat-not-burn tobacco) produced by the thick slurry method using the above-mentioned production method.

[0041] The present invention further provides a heating section of a new type of tobacco (heat-not-burn tobacco) to which a sheet produced by the concentrated slurry method for a new type of tobacco (heat-not-burn tobacco) produced by the manufacturing method of the present invention is added.

[0042] The present invention further provides a new type of heated cigarette having a heating section according to the present invention. [Effects of the Invention]

[0043] In the present invention, additives including additives A, B, and C are added to a concentrated slurry, and the low pressure and temperature are controlled in conjunction with each other, thereby contributing to promoting the exertion of the chemical synergistic effect of the additives, improving flavor components, reducing unpleasant flavors, and improving the taste in tasting evaluations.

[0044] Furthermore, according to the research results of the present invention, innovatively, the use of a component of formula (1) in which R is a heterocycle as additive B, and further use of diammonium dihydrogen phosphate as an additive, combined with two-stage gradient low-pressure conditions, surprisingly further enhanced the synergistic effect, contributing to an improvement in the content of the target aroma components, a reduction in unpleasant flavors, and a significant improvement in the inhalation sensation evaluation effect. [Brief explanation of the drawings]

[0045] [Figure 1] 1 shows a comparison of the aroma components of the sheets produced in Example 1 and Comparative Example 1. Here, the upper spectrum is the spectrum of Example 1, and the lower spectrum is the spectrum of Comparative Example 1. DETAILED DESCRIPTION OF THE INVENTION

[0046] The present invention discloses a new type of cigarette and its heating section with improved sensory evaluation quality, as well as a method for manufacturing a sheet using a thick slurry method. Those skilled in the art can realize the present invention by appropriately improving process parameters while referring to the contents of this specification. It should be noted that all similar substitutions and modifications that are obvious to those skilled in the art are considered to be included in the present invention. The method and application of the present invention have been described through preferred embodiments. Those skilled in the art can realize and apply the technology of the present invention by modifying or appropriately changing and combining the method and application described herein without departing from the content, spirit, and scope of the present invention.

[0047] In the present invention, the initial thickened slurry can be obtained by any method known in the art, for example, by pulping a conventional binder component and tobacco waste.

[0048] For example, 15 kg of sucrose fiber and 450 kg of water were weighed and defibrated in a high-speed hydraulic disintegrator at 5000 rpm for 70 minutes. Next, 3 kg of guar gum, 0.5 kg of xanthan gum, 32 kg of 10% PEG solution, and 5 kg of glycerol were added to the disintegrator and stirred at 5000 rpm for 30 minutes. The resulting mixture was then prepared for subsequent use. Additionally, 60 kg of tobacco mesophyll, 30 kg of tobacco veins, and 10 kg of tea leaves were dry-ground into tobacco chips with a 300-mesh mesh.

[0049] In the present invention, the concentrated slurry modified with the additives and methods of the present invention can be formed into a tobacco sheet by known pulping, drying, and peeling processes. For example, drying may be performed at a temperature of 98°C ± 3°C.

[0050] The present invention will now be further described with reference to the following examples. [Example]

[0051] Step (1): 500 kg of the binder prepared above and 100 kg of the tobacco waste prepared above were mixed according to the batch recipe to obtain a uniformly mixed concentrated slurry (first concentrated slurry). To the first concentrated slurry, ammonium dihydrogen phosphate (Additive A), the compound of formula (1-A) (Additive B), and a mixture of ribose and glucose (weight ratio 1:1) (Additive C) were sequentially added so that the weight ratio of Additive A:Additive B:Additive C was 1:2:1, and the weight ratio of the additives (i.e., the total weight of Additives A to C) to the concentrated slurry was 0.2:1. The pH of the concentrated slurry was then adjusted to 3.5 using phosphoric acid (a pH adjuster), yielding a mixed concentrated slurry.

[0052] Step (2): The mixed thickened slurry obtained in step (1) was continuously stirred at a speed of 400 rpm under a pressure of 0.02 MPa and a low-pressure incubation condition of (85±5)°C for 6 hours to obtain a modified thickened slurry for subsequent use.

[0053] Step (3): Subsequently, the tobacco was pulped, dried, and peeled to form a tobacco sheet, which had a thickness of 0.17 mm and a moisture content of 11.8%.

[0054] This tobacco sheet was rolled up to make a new type of cigarette (heat-not-burn cigarette). Seven professionally trained sensory panelists smoked the tobacco and conducted a sensory evaluation in accordance with the relevant method of "Method for Sensory Evaluation of Reconstituted Tobacco Leaves (Paper Manufacturing Method)" (YC / T498-2014). The average quantification scores are shown in Table 1 below. Comparative Example 1

[0055] Compared to Example 1, the only difference between the two is that the initial thickened slurry from step (1) was directly subjected to the treatment in step (3) to obtain a control tobacco sheet, which had a thickness of 0.18 mm and a moisture content of 11.5%.

[0056] Flavor components of sample tobacco processed by two different methods were analyzed by GC / MS. Gas chromatography parameters included an HP-5MS capillary column (60.0 m x 250 μm x 0.25 μm), an inlet temperature of 250°C, high-purity helium carrier gas, a flow rate of 1.0 mL / min, and a split ratio of 15:1. The temperature program consisted of an initial temperature of 40°C held for 2 minutes, followed by a temperature increase to 280°C at 8°C / min and a 25-minute hold. Mass spectrometry parameters included an electron impact (EI) ionization mode, an ionization energy of 70 eV, an ion source temperature of 230°C, a quadrupole temperature of 150°C, a full scan mode, and a scan range of 35 to 450 amu. Figure 1 shows a comparison of flavor components. It demonstrates that the method of the present invention was able to selectively increase the content of target flavor compounds.

[0057] The new type of cigarette (heat-not-burn cigarette) obtained by rolling this tobacco sheet was smoked by seven specially trained sensory evaluation panelists, and a sensory evaluation was conducted in accordance with the relevant methods of "Method for sensory evaluation of reconstituted tobacco leaves (papermaking method)" (YC / T498-2014).

[0058] As a result, it was found that compared with the control tobacco sheet prepared in Comparative Example 1, the tobacco sheet finally prepared in Example 1 had a significantly improved aroma quality, a richer tobacco aroma, reduced unpleasant flavors, high harmoniousness, and less adhesive odor. The average quantification scores are shown in Table 1 below.

[0059] [Table 1]

[0060] [Table 2]

[0061] 1 and Table 2 show that the content of 2-methylpyrazine in the smoke of the new type of cigarette (heat-not-burn cigarette) rolled with the sheet of Example 1 increased by 15%, the content of furfural increased by 38%, the content of furfuryl alcohol increased by 52.7%, the content of 5-guaiacol increased by 57.5%, and the content of 2-acetylpyrrole increased by 80.8%. In addition, it was found that other typical target flavor components also increased to various degrees. [Example]

[0062] Compared to Example 1, the only difference between the two is that 5 kg of the binder and 1 kg of tobacco waste were mixed to form an initial thick slurry, and then the ingredients and proportions of Additive A, Additive B, and Additive C were changed in the preparation process for the following experimental groups.

[0063] Experimental group A: Additive A was diammonium hydrogen phosphate, and the total amount of additive A was kept constant.

[0064] Experimental group B: Additive B was the compound of formula 1-C, and the total amount of additive B was kept constant.

[0065] Experimental group C: Additive B was a compound of formula 1-A and a compound of formula 1-C in a weight ratio of 1:1, and the total amount of additive B was kept constant.

[0066] Experimental group D: Additive B was a compound of formula (1) in which R is a benzyl group, and the total amount of additive B was kept constant.

[0067] Experimental group E: Additive C was changed to glucose, and the total amount of additive C was kept unchanged.

[0068] Experimental group F: The weight ratio of additive A, additive B, and additive C in the additive was 1:10:10, and the weight ratio of additive to concentrated slurry was 0.1:1. [Example]

[0069] The only difference between Example 2C and Example 2C is the use of a low-pressure two-stage gradient treatment in step (2). The specific procedure differs in that the mixed concentrated slurry obtained in step (1) was maintained at (60±5)°C for 3 hours under 0.02 MPa, and then heated at (80±5)°C for 3 hours to obtain a modified concentrated slurry.

[0070] When compared with Experimental Group B of Example 2, the only difference between the two is that an equal weight of ammonium lactate was used as additive A.

[0071] Compared with Experimental Group B of Example 2, the only difference between the two is that in Step 2, the pressure during the reaction was normal pressure.

[0072] The samples of Examples 2 and 3 and Comparative Examples 2 and 3 were tasted and evaluated according to the national standard method of Example 1. The results are shown in Table 3 below.

[0073] [Table 3]

[0074] As shown in Table 2, when ammonium dihydrogen phosphate was used as additive A and additive A was combined with a compound of formula (1) (experimental groups B to D) in which R is an aromatic heterocycle, particularly a compound of formula (1-A) and a compound of formula (1-C), a more synergistic effect was produced, promoting the release of the target aroma substances and further improving the taste in the smoking test. Furthermore, when the two-stage low-pressure reaction (Example 3) was further used, the taste of the resulting tobacco sheet in the smoking test was further improved. [Example]

[0075] Compared with Example 1, the two differ in that the additive components and conditions were changed, as follows:

[0076] Step (1): Additive A, which is ammonium phosphate, Additive B, which is a compound of formula (1-B), and Additive C, which is mannose, were added sequentially to the mixed slurry so that the weight ratio of Additive A to Additive B to Additive C was 1:1:1 and the weight ratio of the additives to the concentrated slurry was 0.2:1. The pH of the concentrated slurry was adjusted to 4.0 using phosphoric acid.

[0077] Step (2): The mixed thick slurry obtained in step (1) was stirred at a speed of 300 rpm for 6 hours under low pressure incubation conditions of 0.02 MPa and (60±5)°C, and was prepared for subsequent use.

[0078] Step (3): The tobacco was then pulped, dried, and peeled to form a tobacco sheet, which had a thickness of 0.16 mm and a moisture content of 11.0%. [Example]

[0079] Step (1): 500 kg of the prepared binder and 100 kg of tobacco waste were mixed according to the batch recipe to prepare a uniformly mixed concentrated slurry. To the mixed slurry, ammonium dihydrogen phosphate (Additive A), the compound of formula (1-B) (Additive B), and lyxose (Additive C) were sequentially added so that the weight ratio of additive A:additive B:additive C was 1:1:10 and the weight ratio of additive to concentrated slurry was 0.15:1. The pH of the concentrated slurry was then adjusted to 5.0 using phosphoric acid.

[0080] Step (2): The mixed thick slurry obtained in step (1) was stirred at 300 rpm for 8 hours under low pressure incubation conditions of 0.02 MPa and (70±5)°C, and was prepared for subsequent use.

[0081] Step (3): The tobacco was then pulped, dried, and peeled to form a tobacco sheet, which had a thickness of 0.17 mm and a moisture content of 11.3%. [Example]

[0082] Step (1): 500 kg of the prepared binder and 100 kg of tobacco waste were mixed according to the batch recipe to form a uniformly mixed concentrated slurry. To the mixed slurry, ammonium dihydrogen phosphate (Additive A), the compound of formula (1-B) (Additive B), and arabinose (Additive C) were sequentially added so that the weight ratio of additive A:additive B:additive C was 1:1:5 and the weight ratio of additives to the concentrated slurry was 0.10:1. The pH of the concentrated slurry was then adjusted to 4.5 using phosphoric acid.

[0083] Step (2): The mixed thick slurry obtained in step (1) was kept stirring at a speed of 500 rpm for 8 hours under low pressure incubation conditions of 0.15 MPa and (60±5)°C, and then prepared for further use.

[0084] Step (3): The tobacco was then pulped, dried, and peeled to form a tobacco sheet, which had a thickness of 0.18 mm and a moisture content of 11.8%.

[0085] Smoking test evaluation was carried out for Examples 4 to 6 according to the method described in Example 1. The results are shown in Table 4 below.

[0086] [Table 4]

[0087] Thus, the process of the present invention, through the use of the additives and low-pressure reaction, can unexpectedly improve the release of target aroma substances in the prepared tobacco sheets.

[0088] The above has provided a detailed introduction to the new type of cigarette with improved sensory evaluation quality and its sheet manufacturing method using a heating section and a concentrated slurry method according to the present invention. While specific examples have been used in this specification to explain the principles and embodiments of the present invention, the explanations of the above embodiments are merely intended to facilitate understanding of the method and core concepts of the present invention. It should be noted that those skilled in the art may make improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications should also fall within the scope of protection of the claims of the present invention.
