[Composition manufacturing process]
The composition manufacturing process is not particularly limited as long as at least nicotine, a base material, a sugar alcohol, a polyglycerin fatty acid ester and a release agent can be mixed to manufacture the oral composition. For example, an oral composition can be produced by putting all raw materials into a mixer and mixing them. In addition, each component mentioned above can be used as each raw material in a composition manufacturing process.

First, nicotine, a base material, a sugar alcohol, a release agent, and, if necessary, water and other substances such as sweeteners, flavors, moisturizers, etc. are mixed to obtain a first mixture. At this time, heating may be applied as necessary. In addition, the order of mixing the raw materials is not particularly limited, and they may be put into the mixer in any order or at the same time and mixed. After uniformly mixing the solid raw materials, the liquid raw materials are added and further mixed. The latter is preferred.

Next, while stirring the obtained first mixture, the polyglycerin fatty acid ester solution is sprayed on the first mixture, thereby mixing the first mixture and the polyglycerin fatty acid ester, and forming the second mixture. obtain. Since the polyglycerol fatty acid ester exerts an anti-caking effect, caking is less likely to occur in subsequent steps. The solvent for the polyglycerin fatty acid ester solution is not particularly limited as long as it can dissolve the polyglycerin fatty acid ester, but alcoholic solvents such as ethanol are preferred. In order not to leave a large amount of the solvent of the polyglycerin fatty acid ester solution in the second mixture, heat treatment may be performed during or after spraying the polyglycerin fatty acid ester solution to the first mixture.

Further, after preparing the second mixture, a process of drying the second mixture may be performed (drying step). After that, a cooling process may be performed. Cooling may be natural cooling, or may be performed using some cooling means (cooling step). Drying can be used to adjust the moisture content of the second mixture to a desired value, for example between 5 and 60% by weight. This facilitates adjustment of the water content in the oral composition as a target product.

An aqueous solution containing a pH adjuster, a sweetener such as acesulfame potassium, a flavoring agent such as menthol, a bitterness inhibitor such as soybean lecithin, and glycerin are added to the mixture obtained in the above step (or drying step, cooling step), if necessary. (additive addition step) to obtain a desired oral composition.
When adding the above additives, etc., they may be solid or may be added in the form of an aqueous solution dissolved in water. When it is added in the form of an aqueous solution, it may be dissolved in a predetermined amount of water in advance and added so as to have the final moisture content of the oral pouch product.

[Packaging process]
The oral composition obtained in the above composition manufacturing process is packaged with a packaging material to obtain an oral pouch product (packaging process). The method of packaging is not particularly limited, and a known method can be applied. For example, a known method such as a method of sealing after putting the oral composition into a bag-shaped nonwoven fabric can be used.
In the packaging process, after the oral composition is put into the packaging material and after the packaging material is sealed, water may be further added in order to obtain an oral composition having a desired moisture content (water addition step ). For example, when the water content of the target oral composition is 50% by weight and the water content of the oral composition obtained in the above composition manufacturing process is 15% by weight, the remaining 35 Add water for weight percent.

<Uses of oral pouch products>
Applications (modes of use) of oral pouch products are not particularly limited, but examples include oral tobacco such as chewing tobacco, snuff, and compressed tobacco; nicotine-containing preparations called nicotine pouches; and the like.

The average particle size D50 of fine silicon dioxide was 3.3 μm.
Next, while stirring the resulting mixture, about 6 mL of an ethanol solution containing about 70% by weight of diglycerin monooleate (Poem DO-100V manufactured by Riken Vitamin Co., Ltd.) was added to the mixture. was sprayed so that the amount added to the mixture was 3.5 g. Thereafter, ethanol was removed by heating to obtain an oral composition.

(Examples 2 to 5, Comparative Example 1)
An oral composition was obtained in the same manner as in Example 1, except that the amounts of raw materials used were changed so that the composition of the oral composition was as shown in Table 1.

(Comparative example 2)
Nicotine Polacrilex (20% Nicotine Polacrilex from Contraf nicotex) 10.1 g, microcrystalline cellulose (MCC) 23.5 g, maltitol 34.7 g, trisodium phosphate 12.4 g, fragrance 3.3 g, and 2.1 g of viscopolysaccharide was mixed. While continuing to mix, 13.8 g of glycerin was added to these mixtures and further mixed to obtain an oral composition.

(Comparative example 2)
An oral composition was obtained in the same manner as in Comparative Example 1, except that the amount of each raw material used was changed as shown in Table 1.

(Adhesion, Viscosity and Stickiness to Production Equipment of Oral Composition)
The adhesion of the oral composition to the manufacturing apparatus indicates whether or not the oral composition adheres to the manufacturing apparatus after manufacturing the oral composition. It was evaluated by visually observing whether or not it was attached and integrated. In addition, the stickiness of the oral cavity composition was evaluated by visual observation. Evaluation criteria are as follows. In addition, in the following evaluation criteria, if it is S, A, or B, there is no practical problem.
Table 1 shows the evaluation results.
S: Almost no adhesion of the composition for oral cavity to the manufacturing apparatus was observed. In addition, the composition for oral cavity had no stickiness, had moderate viscosity, and each component was integrally bound.
A: Almost no adhesion of the oral cavity composition to the manufacturing apparatus was observed. In addition, although the composition for oral cavity was not sticky, the viscosity was slightly insufficient and each component was not bound together, resulting in dryness.
B: Slight adhesion of the oral cavity composition to the manufacturing apparatus was observed. In addition, although the composition for oral cavity had a slightly high viscosity and each component was bound together, it was somewhat sticky.
C: Adhesion of the oral cavity composition to the manufacturing apparatus was observed. Also, the oral composition had excessive viscosity, and although each component was bound together, it was strongly sticky.

(result)
From Table 1, in Comparative Example 1 in which neither fine silicon dioxide nor diglycerin monooleate was blended in the oral composition, and in Comparative Example 2 in which only diglycerin monooleate was blended, the oral composition The product was highly viscous and adhered to the manufacturing equipment. In addition, the oral compositions obtained in Comparative Examples 1 and 2 were highly sticky, indicating that they did not provide good feeling and flavor.

On the other hand, in the oral compositions containing both fine silicon dioxide and diglycerin monooleate (Examples 1 to 5), the viscosities were adjusted within an appropriate range, and each component was bound together. . In addition, no adhesion of the oral cavity composition to the production equipment occurred, indicating that high production efficiency can be achieved.
Furthermore, from Table 1, it was confirmed that the less diglycerol monooleate relative to fine silicon dioxide, the more dry, and the more, the more sticky. More specifically, when the amount of diglycerin monooleate is about 3.0 to 25.0% by weight with respect to 2.0% by weight of fine silicon dioxide, there is practically no problem of dryness and stickiness (Example 1). ~ 5), it was found that by setting it to 5.0 to 15.0% by weight, it is possible to obtain an oral composition that is free from dryness and stickiness, and has a good feeling of use such as texture and flavor (Examples 2 to 4).

<Preparation of Oral Composition II: Examination of Types of Polyglycerin Fatty Acid Esters>
(Examples 6 to 10)
An oral composition was obtained in the same manner as in Example 3, except that the oligoglycerin fatty acid ester was changed from diglycerin monooleate to those shown in Table 2.

(Adhesion, Viscosity and Stickiness to Production Equipment of Oral Composition)
The same method and criteria as in Example 1 were used to evaluate the adhesiveness, viscosity, and stickiness of the oral cavity composition to the manufacturing apparatus. Table 2 shows the results. Table 2 and FIG. 1 also show the results of Example 3, Example 1, and Comparative Example 1 for comparison.

(Liquidity)
The shear stress of the oral composition at a vertical stress of 3 to 7 kPa was measured under the following measurement conditions using a powder rheometer FT4 manufactured by Freeman Technology Co., Ltd. as a rheometer.
・Measurement mode: standard program (25mm_shear_9kPa)
・Measurement temperature: 22°C
・Measurement humidity: 60% RH
・Measurement container: Cylindrical container with an inner diameter of 25 mm and a volume of 10 ml
・Vertical load: 3 to 9 kPa
Each raw material to be measured was passed through a sieve (1.18 mm mesh size) to make fine and uniform particles, which was used as a measurement sample, and measured according to the procedure of the rheometer described above. The measurement results are shown in Table 2 and FIG. For comparison, Table 2 and FIG. 1 show Example 3, which had the highest evaluation results among Examples 1 to 5, Example 1, which was somewhat dry, Example 5, which was somewhat sticky, and The measurement results of the composition for oral cavity of Comparative Example 1, which was highly sticky, are also shown.

(result)
From Table 2 and FIG. 1, comparing the shear stress at a normal stress of 5.0 kPa, the oral composition of Comparative Example 1, which contained neither fine silicon dioxide nor diglycerin monooleate and was strongly sticky, was 5.0 kPa. The oral composition of Example 5, which was as high as .89 kPa and was somewhat sticky, was 5.81 kPa, which was lower than Comparative Example 1, and the oral composition of Example 1, which was somewhat dry, was even lower at 4.25 kPa. , and the oral cavity composition of Example 3, which was free of dryness and stickiness, had a viscosity of 4.81 kPa, which is roughly the median value of Examples 1 and 5.
From these results, it was confirmed that the stronger the stickiness, the higher the shear stress, and the stronger the dryness, the lower the shear stress. Further, by setting the shear stress of the composition for oral cavity between the shear stresses in Examples 1 and 5, particularly around the median value, it is possible to achieve high production efficiency, good flavor, etc. of the composition for oral cavity. all right.
In addition, even when decaglycerin laurate, decaglycerin oleate, or decaglycerin stearate was used as the polyglycerin fatty acid ester instead of diglycerin monooleate (Examples 6 to 8), adhesion to the production equipment and the shear stress was between the oral compositions of Examples 1 and 5. From these results, it was shown that by blending various polyglycerin fatty acid esters with a degree of polymerization of glycerin of 2 or more and 10 or less in addition to the release agent, the production efficiency, flavor, etc. of the oral composition are improved. .

<Production of oral pouch products>
Each of the oral compositions described above is put into a non-woven fabric (manufactured by BFF technical fabrics, basis weight 27.0 g/m ² ) so as to be 0.65 g/piece, for example, and then sealed by heat sealing. An oral pouch product was thus produced.

As described above, according to the present invention, it is possible to provide an oral pouch product that is less sticky and can impart a good flavor.
Further, according to the present invention, in the production of oral pouch products, there is provided a method capable of reducing inconveniences such as adhesion of the oral composition to the manufacturing apparatus and improving the flavor of the oral pouch products. can do.
