• known methods for producing tobacco sheets include methods in which they are produced via a sheet-forming (paper making) process, methods in which they are produced via a slurry (casting) process, methods in which they are produced via a calendering (rolling) process, and methods in which they are produced via an extrusion moulding process.
• the amount of Cu 2+ that is reduced is proportional to the amount of protein contained in the solution.
• two molecules of bicinchoninic acid (BCA) are coordinated to Cu + to form a bluish-purple complex exhibiting strong absorption at 562 nm.
• the amount of protein is calculated via colourimetric determination by spectrophotometry of the complex.
• the ash content is calculated based on the weight of a given amount ashed at a temperature of 550 to 600°C.
• a starch content of 1 wt% or more will allow the tobacco sheet to be made stronger.
• the content of the starch in the tobacco formulation can be the value calculated on the basis of the solids, minus the medium.
• the tobacco sheet of the present invention comprises:
• the tobacco sheet can be formed by removing the medium from the tobacco formulation. Therefore, as described in "(3) Determination of Content of Poorly Water-Soluble Substance" in the Examples below, the content (wt %) (calculated on the basis of solids) of the poorly water-soluble substance in the tobacco formulation described above can be considered to be equal to the content (wt%) of the poorly water-soluble substance in the tobacco sheet.
• the content of the poorly water-soluble substance in the tobacco sheet can also be calculated based on the aforementioned Prosky method.
• the tobacco raw material serving as the poorly water-soluble substance raw material is not particularly limited but can be the same as the tobacco raw material described in "1. Tobacco raw material" noted above.
• a starch content of 1 wt% or more will allow the tobacco sheet to be made stronger.

• the lower limit of the content of the tobacco raw material-derived ingredients in the tobacco sheet is not particularly limited but, in the interests of ensuring functionality as a substrate, is preferably 10 wt% or more, more preferably 15 wt% or more, and ideally 20 wt% or more, but can also be 75 wt% or more, or 90 wt% or more.
• the upper limit of the content of the tobacco raw material-derived ingredients in the tobacco sheet is not particularly limited but can be 80 wt% or less, 70 wt% or less, or 50 wt% or less.
• any combination of upper and lower limits of the tobacco raw material-derived ingredients in the tobacco sheet can be used.
• the content of the ingredients derived from the tobacco raw material in the tobacco sheet can be calculated as the proportion of the weight of said tobacco raw material relative to the total weight of the tobacco raw material that is used and any externally added ingredients.
• the tobacco sheet can further comprise an aerosol-generating agent.
• the aerosol-generating agent is not particularly limited but can include glycerin, 1,2-propanediol, 1,3-propanediol, or a mixture of two or more of these.
• the content of the aerosol-generating agent in the tobacco sheet is not particularly limited, but in the interests of the volume of smoke during smoking, is preferably 10 to 50 wt%, more preferably 15 to 45 wt%, and ideally 20 to 25 wt%.
• the tobacco sheet can further comprise glucan.
• Glucan is a type of binder, as described below. Examples of glucan are not particularly limited but can include tamarind gum, guar gum, locust bean gum, gellan gum, pullulan, or a mixture of two or more of these.
• the content of the glucan in the tobacco sheet is not particularly limited, but in the interests of formability, is preferably 0.1 to 5 wt%, more preferably 0.5 to 2 wt%, and ideally 1. 0-1. 5% by weight.
• the tobacco sheet can comprise a binder.
• starch that functions as a binder in the present invention allows a tobacco sheet that does not contain any binders other than starch to be produced. If the tobacco sheet contains a binder in the form of an impurity, the content of the binder other than starch in the tobacco sheet can be 3 wt% or less, 1 wt% or less, or 0.5 wt% or less.

• the tobacco sheet of the present invention is not particularly limited, but can be made in the form of the molded tobacco formulation described in the "1.Tobacco Formulation" section described above.
• the pressure must be high enough to allow the starch to be released from the cells.
• the average pressure during extraction is preferably 20 to 117 kPa, more preferably 50 to 110 kPa, and ideally 85 to 95 kPa.
• the maximum pressure during extraction is preferably 70 to 117 kPa, more preferably 80 to 116.5 kPa, and ideally 90 to 116.5 kPa. Ensuring that the average pressure or maximum pressure is within said numerical range will allow the cellulose to be efficiently released from the cells.
• the extraction process is preferably 20 to 90 minutes long, more preferably 60 to 80 minutes long, and ideally 65 to 70 minutes long. Ensuring that the duration of the extraction process is within the above numerical range will allow the cellulose to be efficiently released from the cells.
• the extraction process can be carried out 1 to 2 times, 3 to 4 times, or 5 to 10 times; the higher the number of times, the more efficiently the starch can be released. Ensuring that the extraction process is carried out a number of times within the above numerical range will allow the cellulose to be efficiently released from the cells.
• the tobacco raw material undergoing extraction preferably has a large surface area.
• a process for grinding the tobacco raw material should therefore be provided in advance to allow the powdered tobacco raw material to be extracted.
• dry grinding is preferred.
• Known machines can be used for dry grinding.
• the particle size distribution of the powdered tobacco raw material is not limited but should preferably have a D90 of less than 500 ⁇ m and more preferably a D90 less than 100 ⁇ m.

• the tobacco raw material may be ground at the same time as when extracted.
• the tobacco raw material can be extracted while wet ground.
• Wet grinding is preferably carried out in a closed system.
• the particle size distribution of the wet ground tobacco raw material is as described above.
• the method for producing the tobacco formulation can further comprise the step of adding an aerosol-generating agent, a binder, or a combination thereof.

• Other poorly water-soluble substances are poorly water-soluble substances other than the poorly water-soluble substances derived from the tobacco raw material described above.
• the tobacco sheet can be formed without externally adding another poorly water-soluble substance raw material to the tobacco formulation.
• the type of methods for producing the tobacco sheet of the present invention is not particularly limited, and known methods such as paper-making techniques and casting methods can be employed. Of these methods, casting methods are preferred in the interests of the homogeneity of the resulting sheet.
• the method for producing the tobacco sheet of the present invention can comprise a step in which a tobacco formulation is prepared by the method described above and a step in which the tobacco formulation is spread on a substrate and is then dried.
• the method for producing the tobacco sheet need not comprise the step of grinding the tobacco formulation if the tobacco raw material is ground in the step for preparing the tobacco formulation.
• Examples of methods for forming a tobacco sheet via a casting method include methods comprising the following steps:
• the tobacco filler of the present invention comprises the tobacco sheet described above.
• the smoking product of the present invention also comprises the tobacco filler.
• the smoking product of the present invention can be a heat-not-burn smoking product.
• smoking product means an aspiration product upon which a user draws to experience flavour.
• Smoking products can be broadly divided into burning smoking products, such as conventional cigarettes, and heat-not-burn smoking products.
• the results of Table 1 also show that the content of the poorly water-soluble substance in the suspension of Example 2 (12 wt%) was lower than the content of the poorly water-soluble substance in the suspension of Example 1 (30 wt %). This is attributed to the fact that the number of boiling treatments in Example 2 is higher than in Example 1, which thus allows more of a component such as starch to be extracted from the tobacco raw material, and the greater amount in turn results in that much less of the measured amount of the poorly water-soluble substance.
• the results of Examples 1 and 2 show that changing the conditions of the boiling treatment allows the amount of extracted components such as starch to be controlled.
