Description of the Invention: [Technical Field] The present invention relates to a method for producing a non-combustible tobacco sheet, and more particularly to an improvement of the flavor tasted by a smoker when smoking (hereinafter referred to as smoke, fragrance) A method of producing a non-combustible tobacco sheet. [Prior Art] Often accompanied by the burning of tobacco, there are cases where smoke and poor combustion products are generated. In response to such a situation, a non-combustion type scented smoking article which does not generate smoke or a non-combustible product is developed. Among non-combustible scented smoking articles, the tobacco sheet is heated and the vapor-formed tobacco active ingredient is advantageously provided for convenience in construction and use. However, such non-combustible scented smoking articles have a problem that the scent of the scent is too weak. Therefore, a method of improving the tobacco sheet is considered to enhance the performance of the smoke flavor. Patent Document 1 describes a method for treating tobacco by contacting a material of tobacco 0 with water to separate an aqueous extract and insoluble in grass, and then selectively removing nitrate ions contained in the aqueous extract, and then removing The aqueous extract after the nitrate is mixed with the insoluble grass. However, the purpose of this method is to reduce the gas phase components (nitrogen oxides, hydrogen cyanide, and nitric oxide) during combustion by selectively reducing nitrate ions, and is not intended as a non-combustion type user. In addition, there is not much difference between the nicotine amount which is produced by using the processed grass and the cigarette which is produced by using the untreated tobacco, and therefore cannot be improved. The effect of smoke scent. [Patent Document 1] [Patent Document 1] [Patent Document 1] [Patent Document 1] Japanese Laid-Open Patent Publication No. 56-148275 discloses a non-combustion which can improve smoke flavor. The object of the present invention is to provide a tobacco sheet. method. According to the present invention, a practical energy medium, g_method, special = two kinds = grass thin =: separation of the aqueous extract and insoluble in the grass residue = the anion contained in the aqueous extract, obtained minus = ^ The step of hydrating the liquid; adding hydrazine to the treatment liquid having reduced anions to obtain a step of neutralizing the treatment liquid · 立 ~ ^ 丨, 乂 and in the description of the insoluble tobacco residue: second tone, pulp (pulp) After the sheet is formed into a paper form, the treatment liquid is neutralized to obtain a tobacco sheet. Further, for example, the _ sub-exchange is used as the step of selectively reducing the anion contained in the aqueous extract. In the present day, a treatment group added to the above-mentioned subtracted ion is selected from the group consisting of nitric acid, malic acid, citric acid, and succinic acid. The non-combustion of the modified fragrance can be produced by the method of the present invention. [Embodiment] Next, the present invention will be described in more detail in accordance with an embodiment. Prepare 国产本本伯莱烟叶(burley t〇bacc〇) (Bole H) as a raw material for grass. The grass material was shredded, and the 2 parts of the leaf body (iamlna) 321910 201043156 was stirred in 20 times of water, and the aqueous extract and the insoluble tobacco were separated. A weak anion exchange resin (Aroberlite IRA96SB, manufactured by Rohm and Haas Co., Ltd.) was filled in an open column having a diameter of 18 mm. The above aqueous extract was passed through the column at a flow rate of 5 mL/min to obtain a treatment liquid having reduced anions. The reduced anion treatment liquid was concentrated using an Evaporator. The neutralizing treatment liquid is obtained by adding an acid to the pH of the treated liquid having a reduced anion. The acid to be added may be nitric acid, malic acid, citric acid or succinic acid. On the other hand, 7% wt of pulp was blended in the above-mentioned insoluble grass residue, and a sheet was formed by paper making. Further, each neutralizing treatment liquid was applied to the sheet, and dried at room temperature for 2 turns to prepare a tobacco sheet. Thus, the method for producing a tobacco sheet of the present invention has the method of selectively reducing an anion contained in q in an aqueous extract and adding an acid to the treatment liquid of the aqueous extract in comparison with a method for producing a tobacco sheet. And the steps are different in this feature. A tobacco sheet was produced in the same manner as above except that the treatment liquid having reduced anions was not subjected to neutralization treatment. The grass sheet was cut to a size of 10 mm X and a width of 27 mm, and rolled into a cylindrical shape of 10 mm X and 8 mm in diameter. As shown in Fig. 1, a cylindrical tobacco sheet 21 and a cylindrical mouthpiece 30 having a length of 48 mm and a diameter of 8 mm are fitted, and the tobacco sheet 21 and the periphery of the mouthpiece 30 are packaged with high heat conductivity. The material 22 is bundled to join the two. Thermally Conductive Packaging Material 22 5 321910 201043156 A representative example is a rib f|, or a _ paper-bonded paper. Hereinafter, the composite material of the grass sheet 21 and the packaging material 22 is referred to as a roll. As shown in Fig. 2, the secret 2q containing the flakes is inserted into the heater u which forms the hollow cylindrical structure in the heating device 10. Preferably, the heater is formed of a resistor body made of the same material (for example, the same material) as the packaging material 22 of the roll 20. This is because the material on the inner surface of the heater 11 is the same as the material of the packaging material 22 (10), which is not preferable. At least one of the cigarette 20 and the heating device 10 may contain a fragrance (1) avor) or a perfume carrier. From the viewpoint of preservation stability, it is preferred to carry the perfume on the carrier after heating and releasing the fragrance. Figure 3 is a cross-sectional view of the heating device inserted into the final roll containing the final grass sheet. The Crypt 11 which is formed in the crucible structure in the heating device 1Qt is heated to a temperature of 80 phantom 4 (rc). The hollow portion #t of the heater u is inserted into the final roll 2 of the grass sheet. The nozzle 3 is not provided with the size, shape, and material of the mouth 3, so that the mouth 30 is easily contained. Fig. 4 is a perspective view of the heating device 1A. As described above, the heating device 10 has a hollow circle. The heating device 1 of the tubular structure includes a control circuit 12, a temperature sensing n (paste), and a battery 13. The temperature sensor may be, for example, a thermocouple (thermQeGu or a thermistor). The control circuit 12 is operated by the battery 13 and performs feedback control in such a manner that the temperature of the heater u detected by the temperature sensor becomes 8 〇 to 14 。. 201043156 After the cigarette 20 is inserted into the heater 11, the heating is performed by the control circuit 12 by adjusting the heater 11 to 115 ° C for about 10 seconds. If the user smokes the cigarette holder 30 in the same manner as a general cigarette, Can be in the form of a vapor The active ingredient of the tobacco leaf of the scent of smoke. At this time, the tobacco-slice 21 does not generate smoke or combustion products, so that it does not cause troubles around the surroundings, and can enjoy the aroma. Moreover, since the smog which is generally fragrant is not produced Since the burnt portion of the smoke is used, the used cigarette can be easily recycled and discarded. 烟草 The tobacco sheet produced by neutralizing the treatment liquid which has been neutralized with acid for the treatment solution having reduced anions is not used. The tobacco sheet produced by neutralizing the treated anion-reducing treatment liquid is preferably scented. Next, the nicotine content in the tobacco sheet and the pH value of the tobacco sheet are measured by the following operation. The nicotine content was determined by extracting the nicotine remaining in the tobacco sheet after storage for 2 days and quantifying according to GC/MS 0. The pH value of the grass sheet was obtained by storing the final grass sheet having a length of 10 mm X and a width of 27 mm after 2 days. 10 ml of a 0.4 mol/L chlorinated aqueous solution was vortexed and extracted, and measured by an acidity meter. The results obtained are shown in Table 1. It can be understood from Table 1 that the use of neutralization is not carried out. The tobacco sheet prepared by the reduced anion treatment liquid has a very low nicotine content and a high pH value. It is presumed that this is due to volatilization of nicotine during storage. Thus, it is presumed that the tobacco sheet has a high pH value and a low nicotine content. This is the reason why a non-combustible scented smoking article cannot obtain a good scent of smoke. 7 321910 201043156 Table ι·Reducing the nicotine content in the acid sap flakes used in the neutralization treatment of anions _ [mg] ^ Tobacco The pH value of the sheet] ---- the benefit of the suction - 1 -1. 56 - S-------- ς cr has - 0. 13 〇. 〇 ^ ^ ^ QQ with acetic acid 0. 25 — slightly weaker, nitric acid ~* *~~---- 1.24 6 ?
