Description of the Invention: [Technical Field] The present invention relates to a mouth-containing tobacco material, and more particularly to a mouth-containing tobacco material which is excellent in pH stability when stored at room temperature. [Prior Art] In recent years, mouth-end products such as moist-snuff or snus have attracted attention. These mouth-containing products are articles in which a mouth-containing tobacco material containing wet tobacco powder is stored in a water-permeable pouch, and then inserted between the lips and the gums of the oral cavity to enjoy the taste and aroma of the tobacco powder. Since the wet tobacco powder itself is generally weakly acidic (pH about 0.4 to 6.0), it is easy to increase the bacteria. Here, in order to inhibit bacterial thinning to improve storage stability, a pH adjuster is added to the tobacco powder to adjust its pH to a range from about neutral to alkaline. Further, in order to impart a desired flavor, it is adjusted to a desired value in a pH range from about neutral to alkaline. From the standpoint of quality maintenance of the product, it is desirable to maintain the adjusted pH substantially throughout the shelf life. Patent Document 1 proposes the use of a metal hydroxide, a metal carbonate, or a metal hydrogencarbonate as a pH adjuster or a buffer. However, any of these pH adjusting agents or buffering agents are alkaline substances. Patent Document 1 also proposes mixing an inorganic filler with tobacco powder, and the literature describes, for example, calcium phosphate, and calcium phosphate is a basic substance. Patent Document 2 proposes a smoking article containing magnesium carbonate as a pH adjuster in order to make the tobacco material alkaline. However, magnesium carbonate is an alkaline substance 3 322982 201200039. In addition to magnesium carbonate, Patent Document 2 uses an additional pH adjuster, and examples thereof include sodium carbonate and phosphate. However, the use of these additional pH adjusters is intended to allow the tobacco material to rapidly have a desired pH (neutral to alkaline). Therefore, the phosphates described can be considered to be basic. In order for the wet tobacco powder to have the desired neutral to alkaline pH, it is necessary to clearly determine the desired setting for the test substance. Further, in order to allow the grass powder to have a desired pH value, the amount of the test substance used is small, so that the adjusted pH value cannot be maintained for a long period of time. Here, the mouth-containing tobacco material containing the tobacco powder which adjusts the initial pH using only the alkaline substance has to be stored at a low temperature (-20 ° (: to -10 ° 〇, not at room temperature. In addition, When the preservation stability is maintained for a long period of time and a large amount of alkaline substance is added to the tobacco-containing material, the pH value will rise sharply, and the mucosa will be damaged if it is inserted into the cavity. The mouth of the inlet containing the wet tobacco powder contains In the case of the smoky material, it is desirable that the pH value is 8.5 or less. [Prior Art Document] [Patent Document] [Patent Document 1] Japanese Patent Publication No. 2009-508523 [Patent Document 2] International Publication No. WO 2009/082331 [ Disclosure of the Invention (Problems to be Solved by the Invention) An object of the present invention is to provide a material which can have excellent storage stability at room temperature for a long period of time. (Method for solving the problem) 322982 201200039 According to the present month The mouth contains the final material, which is contained in the grass powder and the acid salt of the carbonic acid and the acid salt of the phosphoric acid as the pH adjustment (4). The final content of the test salt and the acidic acid salt of the city is the final grass. Dry weight of powder 6% by weight or more, and the initial pH value of the material contained in the mouth is 7 to ^ 8.5. The water content of the mouth-containing material has a π weight% or more (the effect of the invention) The mouth 3 tobacco material contains a relatively large amount of pH adjuster, and therefore has excellent storage stability over a long period of time at room temperature. [Embodiment] Hereinafter, various aspects of the present invention will be described in detail. a grass powder and an acid salt of a ruthenium salt of a ruthenium acid as an acid salt of a ruthenium acid as a p Η Η 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The initial pH value of the tobacco-containing material is 7 to 85. The moisture content of the tobacco-containing material is 15% by weight or more. The initial pH value indicates the pH value adjusted by the pH adjusting agent. Tobacco powder comprises: a mixture of de-stalked tobacco leaf powder, a mixture of stalk-leaf tobacco leaf powder and tobacco leaf stalk powder, a reconstituted tobacco powder, a reconstituted tobacco powder and a stalked tobacco leaf powder, and a tobacco variety such as bailey tobacco (Bur 1 ey To Bacco), br ght Tobacco, Oriental tobacco, Dark cured tobacco, Rustica tobacco, etc. 5 322982 201200039 Contains the whole agent contained in the material It is a combination of acidic acid salts of carbonic acid. The carbonate salt is preferably selected from the group consisting of sodium carbonate and L i . It is also possible to use the alkalinity of these carbonic acids. It is difficult to select a group consisting of bis-hydrogen hydride and bisphedoic acid. It is also possible to (iv) a mixture of the acid salts of the acid. The acid salt of the basic salt of the carbonic acid and the acid salt of the phosphoric acid is such that the initial pH of the tobacco-containing material is from 7 to 8.5, and the total content is 6% by weight or more based on the dry weight of the tobacco powder. If the pH is less than 7, it is difficult to inhibit the proliferation of bacteria. On the other hand, if the pH exceeds 8.5, it is harmful to the oral mucosa. Further, if the total amount of the acid salt of the carbonic acid and the acid salt of phosphoric acid is less than 6% by weight, the long-term storage property at room temperature (15 ° C to 353⁄4 ) deteriorates.至左右的pH值。 The tobacco powder exhibits a pH of about 4.0 to about 6.0. Next, in the present invention, since an acidic substance (acid salt of a can acid) and an inert substance (a basic salt of carbonic acid) are used to adjust the pH of the tobacco-containing material to 7 to 8.5, even if too much alkaline is added. The substance (alkaline carbonate) makes the pH of the mouth-containing material significantly larger than 8.5, and the pH can be adjusted to 7 to 8.5 by acidic substances. Therefore, the amount of the alkaline substance must be clearly determined in comparison with the use of the basic substance to adjust the pH value of the tobacco-containing material to a single value. The present invention adjusts the pH value of the tobacco-containing material to a single value. In this case, the amount of the acidic substance (acidic acid of phosphoric acid) and the basic substance (basic salt of carbonic acid) can be largely changed. The acid salt of phosphoric acid is preferably used in an amount of 1% by weight or more based on the dry weight of the tobacco powder. The acid salt of phosphoric acid is usually used in an amount of 10% by weight or less based on the dry weight of the tobacco powder. Relative to this 6 322982 201200039 citric acid (four) is more than q, Lai Zhizhi, the initial value of the smoked material is 7 to 8.5. 1 ‘ 依 kou The moisture content of the π-containing final material of the present invention is based on the pH adjustment used in the invention of the invention, and the desired effect is exhibited in the material contained in the second or second embodiment. It is usually below 50% by weight. The moisture content of the 4 material enamel can contain additives such as flavoring agents and _agents. Examples of the flavoring agent include menthol, peppermint, amine guanidine (glycine, etc.), plant extracts (eucalyptus, rosemary, grapefruit seed extract (coffee)), = flavonoids, vitamin E, and fate C;, lemon, cut, fructose and other monosaccharides, sugars and other disaccharides, oligosaccharides, other polysaccharides, cinnamon, horseradish (Shan Fan), = mountain 'clove, nourish, very yellow, Zhongxiangzi, Xiaoyan, etc. Xiangxin spice, nine-layer tower, bay leaf, marjoram, oregano, rosemary, sage, tarragon, thyme, sesame, garlic, foreign g, etc. vanilla 缕 菌 菌 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 Rabbit radish, small scent, meat, mace, nutmeg, poppy seeds and other seeds, spices, chocolate, citrus and other fruit flavors, vanilla extract, 'B' vanillic acid, fragrant lemon oil , scented alcohol, lemon oil, etc. The amount of the fragrance may range from 1% by weight to 5% by weight based on the dry weight of the powder. Examples of the wetting agent include polyhydric alcohols such as glycerin and propylene glycol, sugar alcohols such as erythritol, xylitol and sorbitol, and hyaluronic acid. The wetting amount can be used for i% by weight to 5% by weight of the dry weight of the grass powder. Material No. 2 The in-situ (4) material of the invention must first be determined as the moisture content of the original 4 at the end of the material itself.

The pH value is periodically measured in the pH measurement method described later in the storage period. The result is shown in Figure 2. Figure 1 shows the temperature at 25. 〇, Relative Humidity Environment 322982 11 201200039 Saved Results ” The second graph shows the results of storage at a temperature of 35 ° C and a relative humidity of 60%. In the first and second figures, the line segment a is related to the first embodiment. The line segment b is related to the second embodiment, and the line segment c is related to the comparative example ρ. From the results shown in the first and second figures, the mouth of the comparative example 1 is known. If the final material is stored for six months under the environment of temperature 25 ° C and relative humidity of 6〇%, the pH value will decrease by about 0.5. If it is stored for 6 months under the environment of temperature 3yc and relative humidity 60%, the pH value will decrease. u, for this, the mouth tobacco materials of Examples i and 2 can be understood, and the pH value is hardly lowered under any of the storage conditions. The tobacco-containing materials obtained in Examples 3 and 4 and Comparative Examples 2 and 3 were stored in a Long-Guang storage bag (LAMIJIPAL_4, manufactured by Nippon Co., Ltd.) at a temperature of 2 C and a relative humidity of 60% for six months. . During the storage period, the value of Qi is measured periodically with :=. As a result, the line segment d shown in Fig. 3'4 is related to the embodiment 3, and the line segment e is compared with the example 2. The line segment f in Fig. 4 is related to Embodiment 4, line segment: :: Comparative Example 3. As can be seen from the results shown in Figs. 3 and 4, the material of Comparative Example 2, if the temperature is 25X: and the relative humidity is 6_2, the value is lowered by about L2, and the pH of the solid is lowered. Further, in the case of the mouth 6 of the comparative example 3, it is suppressed in the environment of 25 ° C and relative humidity _, and if it is at the temperature Z = relative to this, it is true.敎 method with =^^ , value 抑 ( 四 四 四 四 四 四 四 四 四 四 6 6 6 6 6 6 6 6 6 6 6 6 6 322 322 322 322 322 322 322 322 322 322 322 322 322 322 322 322 322 322 322 322 322 322 322 322 322 322 322 deal with.
