Definitions

  • the present invention relates to a method for producing sheet tobacco, and more particularly to a method for producing sheet tobacco that allows producing sheet tobacco of low formaldehyde emissions.
  • (reconstituted) sheet tobacco denotes a product obtained by processing, for instance, low-quality leaf tobacco and/or a fine powder of leaf veins, generated in tobacco production processes, and then forming the processed product into a sheet shape by rolling or papermaking technique.
  • Sheet tobacco is used as a partial substitute of shredded tobacco contained in paper-rolled tobacco (cigarettes) or the like.
  • treatments are carried out, in the production process of such sheet tobacco, that involve for instance extracting beforehand flavor components (flavor extract) from a raw material, and then adding the extract to the formed sheet tobacco.
  • flavor extract flavor extract
  • combustion smoke of tobacco products contains formaldehyde.
  • Lower aldehydes such as formaldehyde are difficult to remove through adsorption on ordinary smoking filters. It has thus has been proposed to add, to the filters, for instance hydrotalcite (see PTL 1) or basic polypeptides (see PTL 2) for selective removal of formaldehyde.
  • An object of the present invention is to provide a method for producing sheet tobacco that allows producing sheet tobacco low in formaldehyde emissions themselves.
  • sheet tobacco of low formaldehyde emissions is obtained, in the production of sheet tobacco, by: (1) preparing a tobacco material that satisfies specific conditions pertaining to sugar content and glutamine content, and (2) performing a heating treatment on an extract obtained through extraction from the tobacco material using an extraction solvent, and adding the extract to the formed sheet, and perfected the present invention on the basis of that finding.
  • the present invention allows producing sheet tobacco of low formaldehyde emissions.
  • the method for producing sheet tobacco being one aspect of the present invention is characterized by having: a preparation step of preparing a tobacco material having a sugar content of 15,000 ⁇ g/g or higher and a ratio of sugar content with respect to glutamine content (sugar content/glutamine content) of 70 or lower (hereafter also referred to as “preparation step”); an extraction step of obtaining an extract, using an extraction solvent containing water, out of the tobacco material having been prepared in the preparation step (the present step may also referred to as “extraction step” for short); a heating step of heating the extract obtained in the extraction step (the present step may also referred to as “heating step” for short); a forming step of forming, in the shape of a sheet, a residue obtained in the extraction step (the present step may also referred to as “forming step” for short); and an flavoring step of bringing the extract having undergone the heating step into contact with the sheet obtained in the forming step (the
  • sheet tobacco of low formaldehyde emissions can be obtained, in the production of sheet tobacco, by: (1) preparing a tobacco material that satisfies specific conditions pertaining to sugar content and glutamine content; and (2) performing a heating treatment on an extract obtained through extraction from the tobacco material using an extraction solvent, and adding the extract to the formed sheet.
  • the underlying mechanism for the low formaldehyde emissions is not wholly clear, but it is deemed that sugars and amino acids in the extract undergo aminocarbonyl reactions as the extract is heated, becoming denatured into components that are not prone to generating formaldehyde (the heating temperature in this case lies preferably within a temperature range that does not exceed 100°C, from the viewpoint of preserving the flavor of tobacco in a preferred state).
  • Sugars are deemed to be components that give rise to formaldehyde, and it is found that the sheet tobacco of low formaldehyde emissions is achieved by setting the content of amino acids, in particular the content of glutamine, to be a specific or higher content with respect to the content of sugars.
  • the glutamine that contributes to the present invention is preferably included in the tobacco material, since in that case the original taste of the tobacco is not significantly lost.
  • sugar content of 15,000 ⁇ g/g or higher denotes the sugar content mass per mass of dry tobacco material, and indicates that a comparatively high sugar content in the tobacco material potentially entails large formaldehyde emissions. That is, the production method of the present invention is a method that allows producing superior sheet tobacco of low formaldehyde emissions, through the use of such a tobacco material.
  • sucrose in “sugar content” denotes generically the pentasaccharides glucose, fructose, sucrose, maltose and inositol contained in leaf tobacco, and the language “sugar content” denotes the total content mass of the foregoing.
  • the preparation step is a step of preparing a tobacco material having a sugar content of 15,000 ⁇ g/g or higher and a ratio of sugar content with respect to glutamine content (sugar content/glutamine content) of 70 or lower, but the method for preparing the tobacco material is not particularly limited, and may involve for instance selecting a tobacco material that satisfies the above conditions, or blending tobacco materials so as to satisfy the above conditions.
  • a concrete preparation method there may be blended tobacco materials having features pertaining to the sugar content and the content of amino acids (glutamine), of for instance the "flue-cured variety” and “Burley variety".
  • the term "flue-cured variety” denotes generically tobacco dried in accordance with an iron pipe drying method or circulation drying method; the leaf tobacco in this case is yellow in color and, as is known, has a comparatively high sugar content.
  • tobacco material that satisfies the conditions "sugar content of 15,000 ⁇ g/g or higher” and "ratio of sugar content with respect to glutamine content (sugar content/glutamine content) of 70 or lower".
  • tobacco materials may be used other than the flue-cured variety and the Burley variety and may be from a part of the tobacco plant such as the leaves, stems, veins, roots, and flowers.
  • the leaves may be dry leaves having undergone a drying treatment or may be raw leaves not having undergone a drying treatment. As such there is no special limitation on what leaves to be used.
  • the sugar content of the tobacco materials that is prepared is preferably 18,000 ⁇ g/g or higher, more preferably 20,000 ⁇ g/g or higher, and is ordinarily 200,000 ⁇ g/g or lower.
  • the glutamine content in the tobacco material that is prepared is ordinarily 200 ⁇ g/g or higher, preferably 260 ⁇ g/g or higher, and ordinarily 3000 ⁇ g/g or lower.
  • the sugar content with respect to the glutamine content (sugar content/glutamine content) of the tobacco material that is prepared is preferably 50 or lower, more preferably 40 or lower.
  • Sheet tobacco of low formaldehyde emissions is produced easily within the above ranges.
  • the sugar content can be quantified by extracting components, for instance from a powdered tobacco material, using an acetonitrile aqueous solution or the like, and analyzing the extract as-is by high performance liquid chromatography.
  • the glutamine content can be quantified by extracting components, for instance from a powdered tobacco material, using a methanol aqueous solution or the like, and analyzing the extract as-is by high performance liquid chromatography.
  • the extraction step is a step of obtaining an extract, using an extraction solvent containing water, from the tobacco material having been prepared in the preparation step.
  • the extraction method and the extraction conditions are not particularly limited, and known methods and conditions can be selected as appropriate depending on the purpose.
  • water-containing extraction solvent examples include, as components other than water, for instance inorganic acids, organic acids, and alcohols such as ethanol.
