The first smoking material includes a base smoking material, and a phosphate compound added to the base smoking material, wherein the phosphate compound includes phosphorus contained in the phosphate compound. It is added to the base smoking material so that it is about 2 to about 5% of the weight of the base smoking material. The second smoking material is made of a smoking material to which no phosphate compound is added. The first smoking material comprises 20-60% by weight of the mixture and the second smoking material comprises 80-40% by weight of the mixture.

Description

  The present invention relates to tobacco fillers and cigarettes.

  When the cigarette is ignited and smoke-absorbed, the tobacco filler such as cigarettes contained in the cigarette is first pyrolyzed to char, which becomes ash by oxidative combustion. It is known that tar is mainly generated during pyrolysis, and carbon monoxide (CO) is mainly generated during oxidative combustion.

  Several techniques have been proposed to reduce the amount of carbon monoxide generated from cigarettes during smoking. For example, Patent Document 1 discloses that an alkali metal salt is blended in the tobacco cigarette at a ratio of 2 to 5% by weight in order to reduce the amount of CO in cigarette mainstream smoke.

JP 2006-187260 A

  However, the prior art including the technique described in Patent Document 1 that reduces the amount of CO in the mainstream smoke of cigarettes can reduce the amount of CO, but also reduces the amount of tar in the mainstream smoke of cigarettes. The present inventors have found that the carbon monoxide ratio (C / T ratio) cannot be significantly reduced.

  Therefore, an object of the present invention is to provide a tobacco filler and a cigarette that can significantly reduce CO in cigarette mainstream smoke and at the same time significantly reduce the C / T ratio.

  According to the present invention there is provided a tobacco filler comprising a mixture of a first smoking material and a second smoking material. The first smoking material includes a base smoking material, and a phosphate compound added to the base smoking material, wherein the phosphate compound includes phosphorus contained in the phosphate compound. It is added to the base smoking material so that it is about 2 to about 5% of the weight of the base smoking material. The second smoking material is made of a smoking material to which no phosphate compound is added. The first smoking material comprises 20-60% by weight of the mixture and the second smoking material comprises 80-40% by weight of the mixture.

  Hereinafter, various embodiments of the present invention will be described.

  The tobacco filler of the present invention is a first smoking material comprising a base smoking material and a phosphate compound added in a specific amount to the base smoking material, and a smoking material to which no phosphate compound is added A second smoking material comprising the first smoking material and the second smoking material being mixed in a specific ratio.

  The base smoking material to which the phosphate compound is added to provide the first smoking material includes one or more components of the tobacco filler that make up the tobacco rod of a conventional cigarette. Such ingredients include deboned tobacco leaf or fine powder, tobacco leaf bone engraving, reconstituted tobacco sheet engraving and the like.

  The deboned tobacco leaf may or may not be expanded.

  Reconstituted tobacco sheets are well known per se, and are classified into rolled sheets, slurry sheets, and papermaking sheets depending on the production method. Rolled sheets are made of tobacco material waste (tobacco leaf waste, deboned tobacco scrap, powdered tobacco, inner bone, etc.), binder (sodium carboxymethylcellulose, methylcellulose, ethylcellulose, starch, sodium alginate, etc.), reinforcing agent (pulp Defibrated material, etc.) If necessary, add a moisturizer (a mixture of propylene glycol and corn syrup), water resistance imparting agent (glyoxal, etc.) and a small amount of water, and knead the mixture (raw material mixture). It can be manufactured by rolling into a sheet with a pair of rollers and drying. The slurry sheet is made by adding the binder, the reinforcing agent and, if necessary, the moisturizing agent and the water resistance imparting agent to the tobacco material waste and adding a relatively large amount of water to make the tobacco material waste relatively high. A slurry containing a concentration can be prepared, and the slurry can be developed in a sheet form on a support and dried. Furthermore, the papermaking sheet is made by extracting natural tobacco materials (tobacco leaves, middle bones, etc.) with water, obtaining tobacco extract and extraction residue, beating the extraction residue, turning it into fiber, and papermaking it. Can be produced. The tobacco extract is concentrated and added to the papermaking sheet.

  The phosphate compound is added to the base smoking material (eg, tobacco material) in an amount such that the amount of phosphorus contained therein is about 2 to about 5% of the weight of the base smoking material.

  Examples of the phosphoric acid compound include phosphoric acid; dibasic metal monohydrogen phosphate (for example, disodium monohydrogen phosphate, dipotassium monohydrogen phosphate), dialkali metal phosphate (for example, dibasic metal phosphate) Alkali metal salts of phosphoric acid such as monosodium hydrogen, monopotassium dihydrogen phosphate) and trialkali metal phosphates (eg trisodium phosphate, tripotassium phosphate); monoammonium dihydrogen phosphate and hydrogen phosphate Ammonium salt of phosphoric acid such as diammonium (DAP); alkali metal salt of pyrophosphoric acid such as disodium pyrophosphate, tetrasodium pyrophosphate, tetrapotassium pyrophosphate; alkali metal of tripolyphosphoric acid such as pentasodium tripolyphosphate Contains salt. A preferred phosphate compound is DAP. The phosphoric acid compound can be added to the base smoking material by spraying the aqueous solution onto the base smoking material.

  The second smoking material to be mixed with the first smoking material is a smoking material (eg, tobacco material) to which no phosphate compound is added. Such second smoking material includes the smoking material that constitutes a regular cigarette tobacco rod, for example, a deboned tobacco leaf can be used.

  The first smoking material and the second smoking material are mixed in an amount of 20-60% by weight of the former and 80-40% by weight of the latter (total of 100%).

  The tobacco material used as the base smoking material and the second smoking material is not particularly limited in its variety, and yellow tobacco, Burley tobacco, and the like can be suitably used.

  Again, the tobacco filler of the present invention comprises a first smoking material comprising a base smoking material and a phosphate compound added to the base smoking material in the specific amount, and a phosphate compound. A second smoking material containing a non-added smoking material is included, and the first smoking material and the second smoking material are mixed in the specific ratio. In the present invention, the amount of phosphorus is 0.02 × 0.2 × 100 (%) = 0.4% to 0.05 × 0.6 × 100 (%) = 3% throughout the smoking material (tobacco material). It should be noted that the phosphoric acid compound is not added so that In the present invention, the first smoking material and the second smoking material are mixed as uniformly as possible.

  Although the tobacco filler of this invention does not contain smoking materials (tobacco material) other than a 1st smoking material and a 2nd smoking material, the fragrance | flavor for creating the taste of tobacco can be added. Such perfumes are well known in the art.

  As demonstrated in the following examples, the tobacco filler in which the first smoking material and the second smoking material are mixed has a significant amount of tar generation compared to the tobacco material to which no phosphate anion is added. However, it significantly reduces CO production and thus significantly lowers C / T. Thus, it can be said that the phosphoric acid compound does not suppress the thermal decomposition of the tobacco material, but acts as a flame retardant for suppressing the oxidative combustion of the char generated by the thermal decomposition.

The cigarette of the present invention includes a (cylindrical) cigarette rod including the tobacco filler rod of the present invention and a cigarette wrapping paper that wraps the outer periphery of the tobacco filler rod. The cigarette of this invention can be manufactured similarly to a normal cigarette except using the tobacco filler of this invention as a tobacco filler. As the cigarette wrapping paper, normal cigarette wrapping paper can be used. Cigarette rods typically have a circumferential length of 17 mm to 26 mm and a length of 49 mm to 90 mm. The tobacco filler can be filled at a packing density of 130-230 mg / cm ³ . A normal cigarette filter can be attached to the base end of the cigarette rod (that is, the downstream end in the direction of smoke absorption) with chip paper. The chip paper can be provided with ventilation holes in the circumferential direction of the cigarette to take in external air and dilute the mainstream smoke of the cigarette.

  EXAMPLES Hereinafter, although an Example demonstrates this invention, this invention is not limited by these Examples.

Example 1
Water of 10 times its weight was added to the middle bone of flue-cured tobacco and heated at 60 ° C. for 1 hour with stirring. The mixture was filtered to obtain an extract and an extraction residue. The extract was concentrated with an evaporator. On the other hand, the extraction residue was beaten to a freeness of 300 to be fiberized. A sheet was prepared from the obtained fiber by a papermaking process and dried. The basis weight of the dried sheet was 60 g / m ² . The total amount of the concentrated extract was applied to the dried sheet with a size press to obtain a reconstituted tobacco sheet.

  After spraying 10 mL or 20 mL of a 10 wt% DAP aqueous solution to 10 g of the obtained reconstituted tobacco sheet, it was dried and DAP was 10 wt% (phosphorus = about 2.40 wt% of the reconstituted tobacco sheet weight). A smoking material sheet to which 20% by weight of the added smoking material sheet and DAP (phosphorus = about 4.79% by weight of the reconstituted tobacco sheet) was added was prepared. Both smoking material sheets were cut, and two types of smoking material cuts (first smoking material) were obtained.

  A quartz tube having an air inflow end and an air outflow end was prepared. A glass fiber filter whose weight was measured in advance was attached to the air outflow end of the quartz tube, and a gas bag was further attached. The quartz tube was filled with 150 mg of each smoking material, and each treated smoking material was heated with infrared rays from the outside of the quartz tube while air was supplied from the air inflow end to the quartz tube at a flow rate of 1000 mL / min. The temperature rising rate of the smoking material was 1000 ° C./min and reached 800 ° C. after 46 seconds. Thereafter, while maintaining the temperature of the smoking material at 800 ° C., air was allowed to flow for 5 seconds at the above flow rate, and then heating was stopped. Even after the heating was stopped, air was allowed to flow for 9 seconds at the above flow rate. Thus, gas was collected for 60 seconds, and particulate matter was captured on the glass filter.

  Next, the gas in the gas bag was applied to a gas chromatograph (Micro GC M200H manufactured by Agilent), and the CO amount was measured. Further, the weight of the filter capturing the particulate matter was measured, and the weight of the filter measured in advance was subtracted from the weight to calculate the total weight of the particulate matter. Next, 10 mL of isopropanol (containing quinoline and ethanol as an internal standard for analysis) was added to the filter that collected the particulate matter to extract the particulate matter. About the extract, the quantity of water and nicotine was quantified by the internal standard method using GC-FID / TCD (Agilent 6890N). The amount of tar was calculated by subtracting the weight of water and nicotine obtained from the total weight of the particulate material.

  The above analysis was also performed on reconstituted tobacco sheet not added with DAP.

  The results are shown in FIG. In FIG. 1, bar graph A shows the result of the time when DAP was not added, bar graph B shows the result of the time when DAP was added 10%, and bar graph C shows the result of the time when DAP was added 20%.

  As can be seen from FIG. 1, the smoking material added with DAP had a tar generation amount of about 20% higher than that without DAP addition, but the CO generation amount decreased by about 30-40%. From this result, it is obvious that when the DAP-added smoking material is blended with a smoking material to which no phosphate compound is added, the amount of CO produced is significantly reduced and the C / T ratio is also significantly reduced.

Example 2
20 parts by weight, 40 parts by weight or 60 parts by weight of the DAP 10% by weight added tobacco sheet obtained in Example 1, respectively, 80 parts by weight, 60 parts by weight, or 60 parts by weight of the reconstituted tobacco sheet to which the DAP is not added Three kinds of tobacco fillers were prepared by mixing with 40 parts by weight. Each cigarette filler was manually wound with general-purpose wrapping paper to produce a cigarette. In each cigarette, the amount of tobacco filler was 730 mg, the length was 57 mm, and the diameter was 8 mm.

  Each cigarette is smoked with a Cambridge filter (the weight of which has been measured in advance) and a 10-line linear smoker (Cerulean SM410) equipped with a gas bag, particulate matter is collected by the Cambridge filter, and smoke is collected in the gas bag. Was collected. The cigarette per puff had a puff time of 2 seconds, a puff volume of 35 mL, and a puff interval of 60 seconds. The cigarette was burned for a length of 49 mm from the tip of the cigarette and the number of passes was recorded. The amount of tar and the amount of CO in tobacco smoke were measured as described in Example 1, and the amount of tar produced and the amount of CO produced per puff were calculated. These analyzes were also performed on cigarettes produced in the same manner using only the reconstituted tobacco sheet not having the DAP added to the tobacco filler. The results are shown in FIG. In FIG. 2, bar graph A shows the result of a cigarette produced using a tobacco filler consisting only of a DAP non-added sheet, and bar graph B shows a tobacco filler containing 20 parts by weight of DAP 10 wt% added sheet. The bar graph C shows the result of the cigarette produced using the tobacco filler containing 40 parts by weight of DAP 10 wt% added sheet, and the bar graph D shows the DAP 10 wt% added sheet. The result of the cigarette produced using the tobacco filler which mix | blended 60 weight part was shown.

  As can be seen from the results shown in FIG. 2, the CO amount per puff decreases as the amount of the phosphoric acid compound added increases as compared to the time when the phosphoric acid compound is not added. There is almost no change in the amount of tar produced (C / T ratio decreases significantly).

Example 3
The reconstituted tobacco sheet was cut in the same manner as in Example 1, except that a 10 wt% aqueous solution of phosphoric acid, potassium phosphate or monoammonium phosphate was used instead of the 10 wt% aqueous DAP solution. Was prepared. Thus, 10% by weight of phosphoric acid (phosphorus = about 3.23% by weight of the reconstituted tobacco sheet) was added, and 10% by weight of potassium phosphate (phosphorus = about 2% of the reconstituted tobacco sheet weight). .32% by weight) was added, and reconstituted tobacco sheet was added with 10% by weight of monoammonium phosphate (phosphorus = about 2.75% by weight of the reconstituted tobacco sheet). 40 parts by weight of each phosphoric acid compound-added tobacco sheet was mixed with 60 parts by weight of the reconstituted tobacco sheet to which no phosphoric acid compound was added to prepare a tobacco filler. The cigarette filler was manually wound with a general-purpose wrapping paper to produce a cigarette. The specifications of each cigarette were the same as in Example 2. These cigarettes were analyzed in the same manner as in Example 2. As a result, the CO amount and tar amount per puff, and the C / T ratio were as shown in Table 1 below. Table 1 also shows the results for cigarettes produced using a tobacco filler containing 40% of the reconstituted tobacco sheet with 10% DAP added.

  As can be seen from the results shown in Table 1, the cigarette produced using the tobacco filler containing the smoking material to which the phosphate compound was added was more puffy than the cigarette produced using the smoking material to which the phosphate anion was not added. The amount of CO per hit decreased by 10 to 20%. In addition, the amount of cigarette tar produced using a tobacco filler containing a smoking material added with a phosphate compound is almost reduced compared to the amount of cigarette tar produced using a smoking material not added with a phosphate compound. (Ie, the C / T ratio decreases).

Example 4
DAP, potassium dihydrogen phosphate, sodium dihydrogen phosphate, dipotassium hydrogen phosphate, disodium hydrogen phosphate, tripotassium phosphate, trisodium phosphate, tetrapotassium pyrophosphate, disodium pyrophosphate, tetrasodium pyrophosphate And an aqueous solution of pentasodium tripolyphosphate, and each aqueous solution was prepared in the same manner as in Example 1 so that the amount of phosphorus contained in the phosphate compound was 3% of the weight of the reconstituted tobacco sheet. Add to the prepared reconstituted tobacco sheet, make 10 kinds of smoking material sheets added with phosphate compound, cut each, and make 10 kinds of phosphate compound added smoking material sheet (first smoking material) Obtained. 40 parts by weight of each of the phosphoric acid compound-added smoking materials is mixed with 60 parts by weight of the yellow seed leaf deboning to obtain 10 kinds of tobacco fillers, and each is used in the same manner as in Example 3 to produce a cigarette. did. Moreover, a cigarette was produced in the same manner as described above except that a reconstituted tobacco sheet not added with a phosphoric acid compound was used. As a result of conducting the same analysis as Example 2 about these cigarettes, C / T ratio per cigarette was as showing in FIG. In FIG. 3, bar graph A shows the results of cigarettes produced using tobacco fillers without addition of phosphate compounds, and bar graph B shows the results of cigarettes produced using tobacco fillers containing DAP-added sheet engravings. Bar graph C shows the results of cigarettes made using tobacco filler containing potassium dihydrogen phosphate-added sheet engraving, and bar graph D made using tobacco filler containing sodium dihydrogen phosphate-added sheet engraved. The results of cigarettes, bar graph E, the results of cigarettes made with tobacco filler containing dipotassium hydrogen phosphate added sheet engraving, and bar graphs F, cigarette filler containing disodium hydrogen phosphate added sheet engraved. The bar graph G shows the results of cigarettes prepared using a tobacco filler containing tripotassium phosphate-added sheet engravings. The bar graph H shows the results of the cigarette made using the tobacco filler containing the trisodium phosphate-added sheet stamp, and the bar graph I shows the tobacco filler containing the tetrapotassium pyrophosphate-added sheet stamp. The results of the cigarettes prepared are shown in a bar graph J. The results of cigarettes prepared using a tobacco filler containing a disodium pyrophosphate-added sheet engraving and the bar graph K show a tobacco filler containing a tetrasodium pyrophosphate-added sheet engraving. The bar graph L shows the results of the cigarette produced using the tobacco filler containing the pentasodium tripolyphosphate added sheet.

  As shown in FIG. 3, cigarettes (bar graphs B to L) prepared using a tobacco filler containing a smoking material to which a phosphate compound is added are cigarettes prepared using a smoking material to which no phosphate compound is added. Compared with (Bar graph A), the C / T ratio was reduced by 5 to 30%.

Example 5
Similar to Example 4 except that the reconstituted tobacco sheet was added with potassium dihydrogen phosphate as phosphorus in amounts of 1.5%, 3%, 6%, 12% of the weight of the reconstituted tobacco sheet. Cigarettes were prepared and analyzed. As a result, the C / T ratio per cigarette was as shown in FIG. 4 (indicated by black circles). FIG. 4 shows the results of cigarettes (white circles) prepared using a tobacco filler containing 40 parts by weight of reconstituted tobacco sheet added with no phosphoric acid compound and 3% of the weight of the reconstituted tobacco sheet. The results (triangles) of cigarettes produced using reconstituted tobacco sheet engraving added in the amount of are also shown.

  As shown in FIG. 4, it was observed that the C / T ratio of cigarette decreased as the addition amount of the phosphate compound increased.

Example 6
In the same manner as in Example 1, 10% by weight of DAP was added to the yellow seed deboned leaves. About this DAP addition time, it carried out similarly to Example 1, and measured CO and a tar production amount. The same measurement was performed on the yellow-type deboned leaves themselves (without DAP addition). The results are shown in FIG. In FIG. 5, bar graph A shows the results for the time when DAP was not added, and bar graph B shows the results for the time when DAP was added.

  As shown in FIG. 5, compared with the time when the phosphate anion was not added, the DAP addition time was almost the same as the tar generation amount, but the CO generation amount was reduced by about 30%. From this result, it is self-evident that when the DAP-added smoking material is blended with a smoking material to which no phosphate anion is added, the CO production is significantly reduced, and at the same time, the C / T ratio is also significantly reduced.
