Definitions

  • the present invention relates to a tobacco sheet for a non-combustion heating flavor inhaler, a non-combustion heating flavor inhaler, and a non-combustion heating flavor inhalation system.
  • a combustion-type flavor inhaler obtains flavor by burning a tobacco filling containing leaf tobacco.
  • a non-combustion heating type flavor inhaler has been proposed that obtains flavor by heating a flavor source such as a tobacco sheet instead of burning it.
  • the heating temperature of the non-combustion-heating flavor inhaler is lower than the combustion temperature of the combustion-type flavor inhaler, for example, about 400° C. or less.
  • an aerosol generating agent can be added to the flavor source in the non-combustion heating type flavor inhaler from the viewpoint of increasing the amount of smoke.
  • the aerosol-generating agent is vaporized by heating to generate an aerosol. Since the aerosol is supplied to the user together with flavor components such as tobacco components, the user can obtain sufficient flavor.
  • a non-combustion heating flavor inhaler can comprise, for example, a tobacco-containing segment filled with tobacco sheets or the like, a cooling segment, and a filter segment.
  • the axial length of the tobacco-containing segment of the non-combustion-heating flavor inhaler is generally shorter than the axial length of the tobacco-containing segment of the normal combustion-type flavor inhaler in relation to the heating heater. Therefore, in the non-combustion heating type flavor inhaler, a large amount of tobacco sheets or the like is filled in the short tobacco-containing segments in order to ensure the amount of aerosol generated during heating.
  • non-combustion heating type flavor inhalers usually use tobacco sheets with low swelling, that is, high density tobacco sheets.
  • the swelling property is a value indicating the volume of a tobacco sheet having a predetermined mass when notches are compressed under a constant pressure for a certain period of time.
  • Patent Literatures 1 and 2 disclose tobacco sheets for use in non-combustion heating flavor inhalers.
  • the present inventors believe that if a tobacco sheet with low swelling (high density) is used, the total heat capacity of the tobacco-containing segment increases. It was found that the tobacco sheet filled in the tobacco-containing segment does not sufficiently contribute to the generation of aerosol depending on the heating method and the capacity of the heater. In order to solve this problem, it is conceivable to reduce the total heat capacity of the tobacco-containing segment.
  • the present inventors (1) reduce the specific heat of the tobacco raw material contained in the tobacco sheet, and (2) use a highly bulky (low-density) tobacco sheet. I considered using it. However, as for (1), it is difficult to reduce the specific heat of the tobacco raw material itself, so it was considered effective to reduce the total heat capacity of the tobacco-containing segment by (2). Therefore, it is desired to develop a highly bulky (low density) tobacco sheet suitable for non-combustion heating type flavor inhalers.
  • An object of the present invention is to provide a highly bulky non-combustion heating flavor inhaler tobacco sheet, a non-combustion heating flavor inhaler including the tobacco sheet, and a non-combustion heating flavor inhalation system.

  • fructose was found to have a low and insufficient effect of suppressing the feeling of flavor and taste inhibition.
  • fructose a panelist commented that the feeling of inhibition of flavor and taste increases in the latter half of smoking (the effect of suppressing the feeling of inhibition of flavor and taste does not last long).
  • a comparative experiment was carried out on the persistence of inhibitory effects on flavor and taste inhibition sensations of type fructans and fructose.
  • the inulin-type fructan suppresses the sensation of flavor and taste inhibition at any content of 0.5 to 3.5% by mass, compared to the 2.0% by mass fructose for comparison. It was found to be excellent in the durability of the effect.
  • fructose at any content of 0.5 to 3.5% by mass, compared to the 2.0% by mass inulin-type fructan for comparison, inhibited flavor and taste. It was found that the persistence of the anti-sensitivity effect was inferior. Inulin-type fructans undergo a process of thermal decomposition before they develop a sweet flavor through a caramelization reaction, so it is thought that they slowly generate a sweet flavor over a long period of time.
  • fructose is thought to generate a sweet flavor in a short period of time through a caramelization reaction. Since the sweet flavor suppresses the sense of inhibition of flavor-smelling taste, it is considered that the difference in duration of the effect of suppressing the sense of inhibition of flavor-drinking taste is caused by the difference in the generation time of the sweet flavor. From the above results, it was confirmed that the inulin-type fructan is superior to fructose in the persistence of the inhibitory effect on flavor and taste inhibition.
