- the filter portion included in the aerosol-generating article may be of a type commonly used in the art to which the present invention pertains.
- a tobacco medium was prepared using the pulverized tobacco material having the same nicotine content.
- Tobacco leaves, tobacco stems, and the like were pulverized, and after making a slurry by including potassium carbonate as a basic pH adjuster, glycerol as an aerosol former, hydroxyethyl guar gum as a binder, water to help form granules, and ethanol as a solvent as shown in the composition in Table 1 below, granules were formed.
- the pulverized tobacco material included in the granules (a) and (b) has a nicotine content of about 2.9 wt%.
- the pH of the granules (a) and (b) at room temperature (about 25 °C) was measured with a pH meter.
- Granule (a) showed a pH of 7.54
- granule (b) showed a pH of 8.87.
- the free-base nicotine content was calculated using the Henderson-Hasselbalch equation of Equation 1 below.
- the free-base nicotine content among the total nicotine content of the granule (a) was 24.87 wt%, and the free-base nicotine content among the total nicotine content of the granule (b) was 87.62 wt%.
- a stick i.e., cigarette
- tobacco medium prepared in experiment 1.(1) above was prepared.
- the amount of nicotine transfer (mg/10 puff) during 10 puffs was measured by heating the stick at a temperature of about 70 °C, and the off-flavor, pungency, and overall preference during smoking were scored on a 7-point scale and an average value is shown in Table 2 below.
- Off-flavor during smoking refers to a taste or aroma that does not harmonize with the original taste or aroma of cigarettes and lowers the value of a product.
- Pungency refers to the degree of stinging, tingling, or pricking sensation in a throat, nose, or mouth 1 second after inhalation. The lower the pungency, the lower the score.
- the overall tobacco taste was evaluated such that the score becomes higher (i.e., closer to 7 points) as the desirability of the cigarette was higher based on the overall flavor of cigarettes felt after inhalation.
- the lower sensory evaluation score for off-flavor and pungency indicates the better evaluation result.
- the higher sensory evaluation score for the overall tobacco taste indicates the better evaluation results.
- the stick containing the tobacco medium with a high pH delivered a larger amount of nicotine even at a low temperature due to the high free-base nicotine content.
- the stick containing the tobacco medium with a high pH granule (b)
- the stick containing the tobacco medium with a high pH had strong off-flavor and pungency during smoking, and a low score was given for the overall tobacco taste.
- Nicotine storage property was evaluated for the tobacco medium prepared in experiment 1.(1) above. It was observed for about 8 weeks under two storage conditions: the medium was opened (OPEN); and the medium was sealed in a plastic bag at room temperature. The results are shown in Table 3 below.
- the tobacco medium with a high pH (granule (b)) showed a high nicotine reduction rate after 8 weeks.
- Tobacco media in the form of granules including the tobacco material with a high nicotine content was prepared (Examples 1 and 2).
- the slurry was formed as in experiment 1.(1) above, by including potassium carbonate as a basic pH adjuster, glycerol as an aerosol former, hydroxyethyl guar gum as a binder, water to help form granules, ethanol as a solvent, as in the composition of Table 4 below, and then granules were formed.
- Comparative Example 1 a slurry was prepared using the pulverized tobacco material having a nicotine content of about 2.9 wt%, in the manner as described above, and then granules were formed.
- Example 1 Example 2 Comparative Example 1 Pulverized tobacco material 100 100 100 Potassium carbonate 3.5 5.0 3.5 Binder 1 1 1 Solvent 64 64 64
- Example 1 For each tobacco medium of Examples 1 and 2 and Comparative Example 1, when a pH was measured with a pH meter at room temperature (about 25 °C), Example 1 showed a pH of 6.6, Example 2 showed a pH of 7.3, and Comparative Example 1 showed a pH of 7.3.
- Example 1 and Comparative Example 1 had the same pH adjuster content, but Comparative Example 1 exhibited a higher pH, indicating a pH of 7.3, which was the same as that of Example 2.
- the free-base nicotine content was calculated using the Henderson-Hasselbalch equation of Equation 1 above.
- the free-base nicotine content among the total nicotine content of Example 1 was 6.6 wt%
- the free-base nicotine content among the total nicotine content of Example 2 and Comparative Example 1 was 16 wt%.
- Sticks containing the tobacco medium of Examples 1 and 2 and Comparative Example in experiment 2.(1) above were prepared. Each stick was filled with 400 mg of tobacco medium and heated to a temperature of about 70 °C, and the amount of nicotine transfer (mg/10 puff) was measured during 10 puffs. The amount of free-base nicotine was calculated and shown in Table 5 below.
- Example 1 Comparative Example 1 An amount of nicotine transfer (mg/10 puff) 0.44 0.76 0.32 Calculated value of free-base nicotine (mg/400mg) 1.00 4.06 1.86
- Example 1 with a low pH showed a higher amount of nicotine transfer.
- Comparative Example 1 and Example 2 had the same pH, but an amount of nicotine transfer of Example 2 was higher than that of Comparative Example 1.
- Comparative Example 1 including a conventional tobacco material having a nicotine content of 0.1 wt% to 3.5 wt%, it can be seen that when the tobacco raw material having a high nicotine content of at least 4 wt% was used as in the example, more nicotine could be transferred at a lower pH, so there were advantages in terms of off-flavor and storability.
