  • Method for recovering stabilized tobacco flavor components and method for producing regenerated tobacco material As described in the Background Art section, it is known to heat a tobacco material to generate a gas containing tobacco flavor components, and dissolve the resulting gas in a liquid to obtain a flavor component-containing liquid. In addition, in the art, it is common to heat a tobacco material in an extraction solvent to extract tobacco flavor components from the tobacco material in order to produce a regenerated tobacco material. In either case, the intention is to separate the tobacco flavor components from the tobacco material and efficiently release the tobacco flavor components using a heated flavor inhaler.
  • tobacco flavor components separated from tobacco materials have a problem of being easily volatilized during subsequent processing steps and storage.
  • the inventors discovered that by heating the tobacco material to generate gas containing the tobacco flavor components and reacting the resulting gas with a base component in water, the organic acids serving as tobacco flavor components are less likely to volatilize and can be stably maintained, which led to the completion of the present invention.
  • the present invention is a "method for recovering a stabilized tobacco flavor component". That is, the method for recovering a stabilized tobacco flavor component includes: heating the tobacco material to vaporize tobacco flavor components from the tobacco material; recovering the tobacco flavor components; and reacting the tobacco flavor component with a base component to obtain a stabilized tobacco flavor component. In another aspect, this method can also be expressed as a "method for stabilizing a tobacco flavor component".
  • the “stabilized tobacco flavor component” may be an ionized product of the tobacco flavor component, or a salt obtained by a chemical reaction between the tobacco flavor component and a base component.
  • the tobacco flavor component is an organic acid
  • the “stabilized tobacco flavor component” may be an organic acid ion, or a salt obtained by a chemical reaction between the organic acid and a base component.
  • the recovery can be performed by passing a gas containing the tobacco flavor components through an inert liquid and recovering the tobacco flavor components in the liquid.
  • the recovery and the reaction can be carried out simultaneously by passing the gas containing the tobacco flavor components through an inert liquid to which the base component has been added.
  • the recovery and the reaction can be carried out simultaneously by bubbling the gas containing the tobacco flavor components into an inert liquid to which the base component has been added.
  • the "method for recovering stabilized tobacco flavor components” includes heating a tobacco material to vaporize the tobacco flavor components from the tobacco material, and bubbling the gas containing the tobacco flavor components into an inert liquid to which a base component has been added to obtain stabilized tobacco flavor components in the liquid. This method may further include a step of drying and concentrating the "bubbling liquid containing tobacco flavor components" obtained in the bubbling step.
  • inert liquid refers to a liquid that is inert (i.e., does not chemically react) to gases, including tobacco flavor components, and base components.
  • gases including tobacco flavor components, and base components.
  • base component refers to a component that can increase the pH of the inert liquid.
  • the "stabilized tobacco flavor component" obtained by the above-mentioned method can be used to produce a regenerated tobacco material. That is, the method for producing a regenerated tobacco material includes the following steps: Obtaining the stabilized tobacco flavor component according to the above-mentioned "method for recovering stabilized tobacco flavor component”; and mixing the stabilized tobacco flavor component with the heated tobacco material to obtain a reconstituted tobacco material.
  • Figure 1 shows a flow chart of an example of a method for producing regenerated tobacco material.
  • Heating process (S1) In the heating step (S1), the tobacco material is heated to vaporize the tobacco flavor components from the tobacco material.
  • the heating step (S1) produces a "gas containing tobacco flavor components" (see FIG. 1).
  • the components include organic acids.
  • tobacco material can be tobacco shreds that are ready to be incorporated into tobacco products, such as combustion-type or heat-type flavor inhalers.
  • tobacco shreds ready to be incorporated into tobacco products refers to tobacco shreds that have been through a drying process on the farm, a long-term aging process of one to several years at a raw material factory, and various other processing steps, such as blending and cutting at a manufacturing factory, and are ready to be incorporated into tobacco products.
  • Tobacco shreds are cut tobacco leaves.
  • the tobacco shreds may be shredded leaves, shredded backbones, shredded reconstituted tobacco (i.e., tobacco material produced by processing leaf waste, shredded waste, backbone waste, fine powder, etc. generated during factory operations into a reusable form), or a mixture of these.
  • the tobacco shreds may be pulverized, and the resulting pulverized material may be used for the heating step (S1).
  • pulverized tobacco shreds as the tobacco material can increase the efficiency of recovery of tobacco flavor components from the tobacco material. This can increase the amount of tobacco flavor components recovered and the amount of tobacco flavor components contained in the final reconstituted tobacco material.
  • the tobacco shreds may be of any variety, such as flue-cured, burley, or oriental, etc.

  • water with added base components is used as the bubbling liquid, but the base components may be added to an inert liquid other than water.
  • Any inert liquid may be used as long as it is inert (i.e. does not chemically react) to the gas containing the tobacco flavor components and the base components.

  • a weak base has the advantage of being highly safe when performing the bubbling step (S2).
  • the base component may be a strong base. That is, the base component may be, for example, a substance that forms hydroxide ions when ionized. Strong bases have the advantage that they are highly efficient at stabilizing tobacco flavor components even when used in small amounts.
  • the base component is, for example, at least one selected from the group consisting of potassium carbonate, sodium carbonate, sodium bicarbonate, sodium carbonate peroxide, sodium hypochlorite, sodium hydroxide, potassium hydroxide, calcium hydroxide, sodium formate, and potassium formate.
  • the base component can be added to the inert liquid (water in this example) so that the pH of the bubbling liquid (reaction mixture) obtained after the bubbling step (S2) is 6.5 to 10.
  • the base component is a weak base, it can be added to an inert liquid (in this example, water) in an amount of, for example, 15 to 100 mg per gram of raw tobacco material.

  • the tobacco flavor components e.g., organic acids
  • the tobacco flavor components are ionized in the bubbling liquid, and are less likely to volatilize due to the presence of counter ions of the base component.
