As described above, in order to maintain the alkalinity of the oral tobacco product, a method of adding a buffer (Patent Document 1) or a specific treatment such as heat treatment of the tobacco material used in the production of the product is known (Patent Literature 2) In addition, in order to maintain the oral tobacco product alkaline, the selection of raw materials has also become an important factor.

In particular, in the case where the amount of the saccharide is large in the tobacco material to be used as the raw material, in the tobacco product adjusted to be alkaline, since the saccharide present in the tobacco leaf material changes during storage to form an acidic substance, the oral tobacco product is The pH is lowered. Therefore, in the oral tobacco product, the Burley species and the Rustica species having a small amount of sugar in the tobacco leaf material are mainly used, and the use of a yellow species having a large sugar content is avoided.

For the above reasons, among the oral tobacco products including SNUS products, only a small range can be selected from a certain number of tobacco raw materials. Raw materials.

Raw materials containing a large amount of sugars such as yellow and oriental species have a demand for use in oral tobacco products from the viewpoints of flavor and taste/supply and demand, but it has been difficult to use until now.

In addition to this, it is known to use sodium chloride as one of the additives used in general oral tobacco products. In addition to reducing the water activity of the oral tobacco product, sodium chloride improves the preservation property, and also imparts a unique taste to the oral tobacco product.

However, from the viewpoint of health, it is desirable to manage the amount of sodium contained in the oral tobacco product in such a manner as to avoid an excessive excess.

The amount of sodium added to the oral tobacco product as an additive is relatively easy to manage, but the amount of sodium contained in the tobacco leaf material is large because the tobacco leaf is an agricultural product, so it is greatly affected by the year of production, the place of production, and the variety. Differently, its management is currently difficult.

In view of the above, a method for producing a reconstituted raw material for oral tobacco used in an oral tobacco product is disclosed in which the saccharide content and the sodium content are adjusted to a predetermined range.

As a result of a review conducted by the inventors of the present invention, a method for producing a regenerated raw material (hereinafter also referred to as a reconstituted tobacco raw material) used in an oral tobacco product is disclosed, which comprises: separating a tobacco leaf material into a solvent-soluble portion by solvent extraction and a step of forming a solvent-insoluble portion and a step of molding the solvent-insoluble portion to obtain a molded article, wherein the solvent-insoluble portion formed by molding does not add an additive other than the solvent-soluble portion, and It is to be understood that the above problems can be solved and the present invention can be achieved.

That is, the present invention is as follows.
