While the problem of aromatic hydrocarbons adhering to leaf tobacco and the problem of generating substances that give irritating sensations such as acetic acid have been solved, tobacco raw materials with increased components that have the characteristic flavor of smoke Can be provided. Moreover, you may use the tobacco raw material manufactured by the method of this invention as a part of tobacco raw material in tobacco products.
  • the tobacco raw material obtained by this invention can be used in arbitrary ratios, when using it as a part of tobacco raw material in tobacco products.
  • Example 1 Drying of leaf tobacco Leaf tobacco immediately after harvesting was dried or trunk-dried, and then naturally dried in a drying room where direct sunlight was not permeable in the range of 25 ° C. to 35 ° C. for about one month. The water content of the dried leaf tobacco was adjusted to 5 to 50% by weight for each sample.
  • a compact smoker (manufactured by Snow Peak Co., Ltd.) was used for the smoked and smoked tobacco apparatus. About 20 g of wood chips were put on the bottom surface, and about 10 g of the leaf tobacco before deboning, which had been dried as described above, was stacked on top and covered. It was installed on a heating device capable of controlling the temperature (manufactured by ASONE Co., Ltd., hot plate CHR-250DN) so that the bottom surface of the smoke-making device was grounded. Next, the preset temperature of the heating device was set to 500 ° C., and the wood chips were pyrolyzed. The thermal decomposition time of the wood chip was 10 minutes, and white oak, walnut, hickory, oak or walnut was used as the smoke generating material. The product temperature of the smoke generating material was adjusted to be about 300 ° C to 600 ° C.

  • the upper part of Lam Zip AL-E was heat-sealed to make a completely sealed system.
  • FIG. 3 shows the measurement results of guaiacol. As is apparent from FIG. 3, it was found that a large amount of guaiacol was contained in the leaf tobacco when the product temperature of the smoke generating material was 400 to 500 ° C., and the most guaiacol was contained at 450 ° C. FIG. 3 also shows the content of guaiacol contained in the original raw material and the content of guaiacol contained in the conventional DFC for comparison. As shown in FIG. 3, guaiacol is hardly contained in the original raw material. This is because guaiacol is produced by thermal decomposition of lignin and is imparted to leaf tobacco by smoke processing.
  • FIG. 4 shows the content of 2,6-dimethoxyphenol contained in the original raw material and the content of 2,6-dimethoxyphenol contained in the conventional DFC for comparison. As shown in FIG. 4, the raw material is almost free of 2,6-dimethoxyphenol. This is because 2,6-dimethoxyphenol is produced by thermal decomposition of lignin and is given to leaf tobacco by smoke treatment.
  • Table 2 The contents of guaiacol and 2,6-dimethoxyphenol are summarized in Table 2 below.
  • the smoked product 1 is heated using a hot plate 2 to be smoked, and the amounts of guaiacol and 2,6-dimethoxyphenol adhering to the leaf tobacco 3 and guaiacol and 2,6-dimethoxyphenol adhering to the filter 4 are measured. Each was measured.

Abstract

L'invention concerne une matière première de tabac ayant une faible teneur en hydrocarbures aromatiques polycycliques spécifiés et en acides carboxyliques de faible poids moléculaire et contenant une grande quantité de composants aromatiques spécifiés, ainsi qu'un procédé de fabrication de la matière première de tabac. L'objectif est atteint grâce à un procédé de fabrication comprenant : une étape consistant à sécher le tabac à feuilles préalablement écôtées après récolte jusqu'à ce que sa teneur en humidité atteigne 10 à 25 % en poids ; une étape consistant à traiter par de la fumée le tabac séché préalablement écôté à l'aide de fumée décomposée thermiquement à 400-500 °C ; et une étape consistant, après l'étape de traitement par de la fumée, à stocker le tabac à feuilles préalablement écoté et traité par de la fumée dans des conditions partiellement hermétiques.
