Description

Nicotine Supply Oral Pouch Products and Their Manufacturing Methods

The present invention relates to a nicotine-supplied oral pouch product and a method for producing the same.

A nicotine-supplied oral pouch product such as an oral tobacco product is a package in which a composition containing nicotine is stored in a pouch (packaging material) formed of a material such as a non-woven fabric. Put it inside and use it.
In nicotine-supplied oral pouch products, by putting it into the oral cavity of the user, components such as nicotine in the composition exude to the outside of the packaging material, and the flavor component is delivered to the user. NS.

In the nicotine-supplied oral pouch product, the feeling of use in the oral cavity at the time of use is important, and the technology for improving the mouthfeel and the technology for improving the familiarity between the product and saliva are known. For example, by reducing the sealing area and the amount of excess air in the product, it is possible to release the desired flavor during use, and the development of a technique for improving the palatability in the oral cavity (Patent Documents). 1) In addition, the development of technology that improves the compatibility between the product and saliva by containing a specific substance in the composition and promotes the rapid transmucosal transmission of the substance in the composition in the oral cavity is progressing. (Patent Document 2).

Special Table 2019-505174 Special Table 2012-522765

As mentioned above, in addition to the ease of release of substances in the composition and the ease of familiarization between the product and saliva, there are other factors that give the oral feeling when using the nicotine-supplied oral pouch product. There is still room for improving the usability.
In a general nicotine-supplied oral pouch product, the present inventors have focused on the fluidity of the composition in the pouch during use and the adhesion between the materials constituting the composition. By increasing the fluidity of the composition in the pouch product, the pouch product can be easily deformed in the direction perpendicular to the direction in which the pressure is applied to the pouch product, so that the user can easily shape the pouch product into a desired shape. It can be deformed and held in the oral cavity. In addition, by reducing the adhesion between the materials constituting the composition, the pouch product can be easily deformed in the direction in which pressure is applied to the pouch product, so that the user can easily make an initial pouch product having a large thickness. It can be deformed thinly.
The above-mentioned improvement in fluidity is an improvement in usability between the time when the user puts the pouch product in the mouth and the saliva soaks into the mouth and the time when the user finishes using the product and takes it out of the mouth. , It is an improvement of usability in the initial stage from the time when the user puts the pouch product in the mouth until the saliva soaks in, and the improvement of the characteristics is also an advantage for the user. The above-mentioned Patent Documents 1 and 2 do not disclose any of these characteristics.

Therefore, it is an object of the present invention to provide a nicotine-supplied oral pouch product having improved fluidity or improved adhesiveness, and a method for producing the same.

As a result of diligent studies, the present inventors can solve the above problems by using a composition containing gel particles containing a specific substance and setting the water content in the composition to a specific value or more. And arrived at the present invention.

The calcium supply source may be supplied as an aqueous solution or a solid, but when supplied as a liquid such as an aqueous solution, calcium can be mixed with other raw materials in the form of calcium ions and is a solid. It is preferable to supply it as an aqueous solution from the viewpoint of higher contact efficiency with the anionic natural polymer calcium than to supply it with. Also, as described above, the calcium source may be added after making the mixture containing the anionic natural polymer carbohydrates or may be mixed first with the anionic natural polymer carbohydrates, producing fine and uniform gel particles. From the viewpoint of allowing the mixture to be added, it is preferable to add the mixture after preparing the mixture containing the anionic natural polymer carbohydrate. On the other hand, it is not preferable to use an anionic natural polymer carbohydrate such as pectin as an aqueous solution from the viewpoint of handling because the viscosity increases when it is made into an aqueous solution.
In the addition of each aqueous solution after the step of preparing the mixture before the addition of the calcium source, water may be added together with each aqueous solution in order to obtain a desired water content.

Specifically, the pH of the mixture before heating is 6.0 or more and 10.0 or less. It is preferable, and it is more preferable that it is 8.0 or more and 9.0 or less.
A sweetening agent such as acesulfame potassium, a fragrance such as menthol, a bitterness inhibitor such as soybean lecithin, and a moisturizer such as glycerin are added (step of adding an additive to a gel particle-containing mixture) to obtain a desired composition.
When the above additives and the like are added, they may be solid or added in an aqueous solution dissolved in water. When added as an aqueous solution, it may be added by dissolving it in a predetermined amount of water in advance so as to have the final water content of the pouch product.

[Packaging process]
The composition obtained in the above composition manufacturing step is packaged with a packaging agent to obtain a pouch product (packaging step). The packaging method is not particularly limited, and a known method can be applied. For example, a known method such as a method of putting the above composition into a bag-shaped non-woven fabric and then sealing it can be used.
