In addition, smoking articles may include solid materials based on tobacco raw materials, such as leaf tobacco, cut filler, reconstituted tobacco, and the like. Smoking materials may contain volatile compounds.

1 is a flowchart exemplarily illustrating a method of manufacturing a smoking article according to some embodiments of the present invention, and FIG.

Referring to Figure 1, the manufacturing method of a smoking article includes the steps of preparing one or more types of tobacco raw materials (S10), blending the prepared tobacco raw materials (S20), cutting, drying and flavoring the blended tobacco raw materials. Step (S30), filling the smoking material portion with cut, dried and flavored tobacco raw material to prepare a smoking material portion, and may include a step (S40) of manufacturing a smoking article including the smoking material portion.

In the step (S10) of preparing one or more kinds of tobacco raw materials, at least one of the one or more kinds of tobacco raw materials may be hot water immersed tobacco raw materials by a method to be described later. For example, the one or more kinds of tobacco raw materials may include at least one of yellow seed leaves, burry seed leaves, orient seed leaves, and plate leaves, and the hot water-immersed tobacco raw material is hot water-immersed yellow seed leaves, hot water-immersed burry. It may include at least one of a seed leaf and a hot-water-deposited orient seed leaf.

On the other hand, when the smoking material part is 100% filled with the hot-water immersed tobacco raw material, the step (S20) of mixing the prepared tobacco raw material may be omitted.

In addition, although not shown, before the step of mixing the prepared tobacco raw material (S20), the tobacco raw material may be pre-processed by different processing methods. As a specific example, each of the main leaves of the xanth species and the main leaves of the Bury species to be used in the formulation is pre-processed by a hot water immersion method, which will be described later, the orient leaves are flavored in a casing method, and the plate leaves may be humidified. The xanth species true leaves, Bury species true leaves, orient seed leaves and plate leaves may be individually processed as described above and then blended.

The step of cutting, drying and flavoring the blended tobacco raw material (S30) may be performed before filling into the smoking material part for quality uniformity according to the uniform mixing of leaf tobacco, and physical quality improvement such as tobacco raw material swellability. As a specific example, the blended tobacco raw material (compressed leaf tobacco, leaf leaf, stem, etc.) is cut to a certain width, and the blended tobacco raw material is dried to maintain a uniform moisture content, impart swelling, and remove odor. In addition to the casing treatment, it is possible to suppress the stimulation of tobacco raw materials and the generation of odors, and to flavor the blended tobacco raw materials to impart a flavor character.

In the step of manufacturing the smoking article (S40), the cut, dried and flavored tobacco raw material may be filled in the smoking material part 120 (refer to FIG. 3), and a smoking article including the smoking material part 100 (refer to FIG. 3) ) can be prepared.

Meanwhile, as described above, at least one of the tobacco raw materials prepared in the step S10 of preparing the tobacco raw material may be a hot water immersed tobacco raw material, and the hot water immersion method of the tobacco raw material will be described later with reference to FIG. 2 . .

Referring to FIG. 2 , the hot water immersion method of tobacco raw materials includes preparing leaf tobacco (S11), immersing the prepared leaf tobacco in hot water (S12), separating the deposited leaf tobacco from hot water (S13), and separated leaf tobacco. It may include a step of dehydrating (S14) and drying the dehydrated leaf tobacco (S15). In addition, although not shown, the hot water immersion method of the tobacco raw material may further include a moisture adjustment step of the tobacco leaf after the drying step (S15).

In the step of preparing the leaf tobacco (S11), the leaf tobacco may be selected from leaf tobacco of various species, such as yellow leaf tobacco, burery Jongyeop, and orient Jongyop. In addition, the raw material to be used is not limited to leaf tobacco, and tobacco raw materials such as plate leaves and stems may be prepared. The moisture of the raw material to be used may be approximately 8% to 15% by weight, but of course, the moisture of the raw material may be different depending on the type of leaf tobacco. For example, the moisture of the true leaves of the xanth species may be about 10% to 12% by weight, and the moisture of the true leaves of the Burberry species may be about 11% to 13% by weight, but is not limited thereto.

In the step of immersing the prepared leaf tobacco in hot water (S12), the temperature of the hot water for immersing the leaf tobacco may be approximately 50°C to 90°C, preferably approximately 60°C to 80°C. If the temperature of the hot water is less than the above range, the effect of reducing the odor component by hot water immersion is insignificant.

In some embodiments, the total weight of the hot water in which the leaf tobacco is to be deposited may be approximately 3 to 25 times (preferably, about 7 to 20 times) relative to the total weight of the prepared leaf tobacco, and the leaf tobacco deposition in the hot water is approximately It may be carried out for 7 minutes to 35 minutes (preferably about 10 minutes to 30 minutes).

When the total weight of hot water is less than the above range, the reduction rate of off-flavor components is remarkably small. As the amount of heat is required, the process efficiency decreases. When the immersion time of leaf tobacco in hot water is less than the above range, the reaction is incomplete in terms of the reaction to reduce the odor component, and when it exceeds the above range, the reaction is terminated and the process efficiency becomes disadvantageous.

Meanwhile, more preferably, the immersion time of leaf tobacco in the hot water may be different depending on the type of leaf tobacco. For example, when the leaf tobacco is a true leaf of a xanth species, the immersion time is preferably about 8 minutes to 22 minutes (more preferably, about 10 minutes to 15 minutes), and when the leaf tobacco is a true leaf of a Bury species, the immersion time is about 18 to 32 minutes (more preferably, about 20 to 25 minutes) may be preferred.

In the step (S13) of separating the deposited leaf tobacco from the hot water, the leaf tobacco immersed in the hot water may be separated from the hot water by sieving the leaf tobacco and discharging the hot water.

In the step of dehydrating the separated leaf tobacco (S14), in order to minimize the deterioration of the physical properties of the leaf tobacco and effectively separate the residual hot water contained in the leaf tobacco, the separated leaf tobacco is pressurized at a pressure of about 1 kgf/cm ² to 10 kgf/cm ² can be In some embodiments, the moisture in leaf tobacco after the dehydration step (S14) may be approximately 30% to 90% by weight.

Drying the dehydrated leaf tobacco (S15) may be performed for additional moisture removal after the dehydration step (S14).

In some embodiments, the moisture of leaf tobacco after the drying step (S15) may be approximately 11% to 15% by weight, in this case, the dried leaf tobacco is combined step (S20) described with reference to FIG. 1 without a separate moisture adjustment ) can be put into

More preferably, the moisture in leaf tobacco after the drying step (S15) may be approximately 5% to 10% by weight. In this case, the hot water immersion method of the tobacco raw material may further include the step of adjusting the moisture in the dried leaf tobacco between the drying step (S15) and the mixing step (S20), and the moisture in the leaf tobacco after the moisture adjustment step is approximately 11 It may be from weight % to 17 weight %. As such, when the moisture adjustment step is additionally performed after the drying step (S15) is performed to a level lower than the moisture content suitable for the subsequent process, even if the final moisture is substantially the same due to the difference in the dissolved components of the dried moisture and the moisture added during adjustment It is more advantageous for the amount of components in the leaf other than moisture and the physical properties of leaf tobacco.

On the other hand, the drying step (S15) may be performed in a plurality of stages. Specifically, the drying step (S15) includes a first natural drying step of naturally drying the dehydrated leaf tobacco, dry heating of the leaf tobacco after the first natural drying step, and a second natural drying of the dry heated leaf tobacco again. It may be carried out through a drying step.

In some embodiments, the first natural drying step is performed in a chamber at about 20° C. to 24° C. for about 1 hour to 40 hours, and the dry heating step is performed at a temperature of about 100° C. to 150° C. under ventilation conditions. It is carried out for minutes to 30 minutes, and the second natural drying step may be performed for 1 to 5 days at a temperature of about 15° C. to 30° C. under ventilation conditions.

The drying step (S15) is performed in a plurality of stages as described above, but each ? When carried out under the above conditions, moisture drying can be efficiently performed without issues such as deterioration of mass productivity of leaf tobacco or deterioration of taste.

3 is a diagram illustrating an exemplary configuration of a smoking article including a leaf tobacco immersed in hot water according to some embodiments of the present invention.

In the present specification, the smoking article 100 has been described as an example of a combustion cigarette, but the present invention is not limited thereto, and the smoking article 100 may be a heated cigarette used together with an aerosol generating device (not shown) such as an electronic cigarette device. of course there is

Referring to FIG. 3 , the smoking article 100 includes a filter part 110 in which a filter wrapper 110a is wrapped, a smoking material part 120 in which the smoking material wrapper 120a is wrapped, and the filter part 110 and It may include a tip paper 130 for coupling the smoking material unit (120).

The filter unit 110 may be disposed downstream of the smoking material unit 120 , and may be a region through which the aerosol material generated in the smoking material unit 120 passes immediately before inhalation by the user.

The filter unit 110 may be formed of various materials, for example, the filter unit 110 may be a cellulose acetate filter. The filter unit 110 may be a cellulose acetate filter in which a fragrance material is not processed, or a transfer jet nozzle system (TJNS) filter in which a fragrance material is processed.

In some embodiments, the filter unit 110 may be a tube-shaped structure including a hollow therein. In addition, the filter unit 110 may be manufactured by inserting a structure such as a film or a tube made of the same or different material inside (eg, hollow).

Although the filter unit 110 of the present embodiment is illustrated as a mono filter including a single filter, it is not limited thereto. For example, it is natural that the filter unit 110 may be provided as a dual filter or a triple filter having two acetate filters in order to increase filter efficiency.

Furthermore, although not shown, a crushable capsule (not shown) having a structure in which an internal liquid containing a fragrance is wrapped with a film may be included in the filter unit 110 .

The above-described filter unit 110 is disposed downstream of the smoking material unit 120, and serves as a filter through which the aerosol material generated in the smoking material unit 120 is passed just before inhalation by the user.

The filter unit 110 may be wrapped by a filter wrapper 110a. The filter wrapper 110a may be made of oil-resistant wrapping paper, and an aluminum foil may be further included on the inner surface of the filter wrapper 110a.

The smoking material part 120 may be wrapped by the smoking material wrapper 120a.

In some embodiments, the smoking material wrapper 120a may have a double wrapper structure, and further, the smoking material wrapper 120a may include one or more Low Ignition Propensity (LIP) bands (not shown) formed on a low ignition cigarette. it may be ji

The filter unit 110 packaged by the filter wrapper 110a and the smoking material unit 120 packaged by the smoking material wrapper 120a may be combined and packaged by the tip paper 130 .

The smoking material unit 120 may be filled with raw tobacco leaf, leaf tobacco, or a mixture of leaf tobacco and leaf tobacco. The mixture may be filled in the smoking material unit 120 in the form of a sheet or cut filler. The smoking material unit 120 may have an elongated rod shape and may have various lengths, circumferences, and diameters.

The smoking material unit 120 may include an aerosol generating material of at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. In addition, the smoking material portion 120 may contain other additive substances such as flavoring agents, wetting agents and/or acetate compounds.

On the other hand, the tobacco taste felt during smoking is mainly determined or affected by the type of smoking material constituting the smoking material unit 120 , whether flavor components are added, and the pretreatment method thereof. Recently, research has been conducted in various fields to enhance the taste of tobacco or to modify the components of aerosols provided from cigarettes. high.

Accordingly, the smoking material unit 120 of the present invention includes the leaf tobacco immersed in hot water, thereby realizing sufficient tobacco taste and taste strength, and at the same time modifying leaf weight components in the leaf tobacco.

On the other hand, the leaf tobacco immersed in hot water according to embodiments of the present invention may be filled in the smoking material unit 120 in various mixing ratios. For example, the smoking material unit 120 may be filled with only hot-water immersed leaf tobacco cut in the form of cut filler without mixing with other smoking materials. Alternatively, the smoking material unit 120 may be mixed and filled with other smoking materials such as hot-water immersed leaf tobacco, non-heat-water-immersed leaf tobacco, plate leaf, toast leaf, puffed corn vinegar, and expanded stem. The weight of the hot-water immersed leaf tobacco included in the smoking material unit 120 may be approximately 10% to 100% of the total weight of the smoking material unit, but is not limited thereto.

On the other hand, the species of the leaf tobacco immersed in hot water may be various. For example, the hot-water-deposited leaf tobacco may be a leaf tobacco such as yellow seed leaf, burry Jong-yeop, orient Jong-yeop, etc., which is hot-water deposited. Preferably, the hot-water-immersed leaf tobacco may be a hot-water-soaked true leaf of a xanth species or a hot-water-immersed Burery species.

Here, the hot-water-immersed xanthophyll leaves may include about 0.5 wt% to 3.0 wt% of nicotine, about 3 wt% to 17 wt% of sugar, and about 0.05 wt% to 1.5 wt% of chlorine. In addition, the hot-water-deposited xanthium leaf may comprise about 0.001 wt% to 0.500 wt% ammonia and about 0.001 wt% to 0.500 wt% nitrate. That is, the hot-water-deposited xanthoma main leaf may contain substantially no ammonia and/or nitrate, or may contain a very small amount.

On the other hand, the hot-water-immersed Burery species main leaf is about 1.0 wt% to 4.0 wt% of nicotine, about 0.1 wt% to 0.4 wt% of ammonia, about 0.05 wt% to 0.9 wt% of sugar, about 0.1 wt% to about 1.0 wt% of nitrate and about 0.05 wt% to 3.0 wt% chlorine.

When the smoking material unit 120 is filled with the hot water-immersed leaf tobacco composed of the above-described component range, the loss of the tobacco's intrinsic taste strength and softness due to the processing of the leaf tobacco can be minimized, and furthermore, when smoking, irritation and It is possible to reduce the taste and improve the overall tobacco taste and clean aftertaste.

Hereinafter, the configuration of the present invention and its effects will be described in more detail through Examples and Comparative Examples. However, these examples are for explaining the present invention in more detail, and the scope of the present invention is not limited to these examples.

Example 1

3 kg of true xanthoma leaves having a moisture content of about 11.5% were immersed in 21 kg of hot water at about 70° C. for about 20 minutes. After immersion in hot water, the weight of the main leaves of xanthium separated from the hot water is about 11.2 kg, and the weight of the main leaves of xanthoma, which is then dehydrated at a pressure of about 2 kgf/cm ² , is about 9.2 kg. The dehydrated xanthophyll leaves were naturally dried (first natural drying) while placed on a tray in a chamber with an internal temperature of 22°C for about 36 hours, and then dry-heated at a temperature of about 125°C for about 14 minutes under ventilation conditions. . After the heat treatment was completed, the main leaves of the yellow species were naturally dried again (second natural drying) for 3 days at a temperature of about 25°C under ventilation conditions. Xanthomatous true leaves were prepared.

Example 2

3 kg of burry species with a moisture content of about 12.1% were immersed in 21 kg of hot water at about 70° C. for about 20 minutes. After hot water immersion, the weight of the original leaf of Buryi species separated from the hot water was about 10.7 kg, and the weight of leaf tobacco dehydrated at a pressure of about 2 kgf/cm ² after that was about 7.4 kg. The dehydrated burery leaves were naturally dried (first natural drying) while placed on a tray in a chamber with an internal temperature of 22°C for about 12 hours, and then dry heated at a temperature of about 125°C for about 14 minutes under ventilation conditions. became After the heat treatment was completed, the main leaves of the burberry species were naturally dried again (second natural drying) for 3 days at a temperature of about 25°C under ventilation conditions, and then water adjustment (moisture addition) was performed for moisture suitable for the subsequent process, followed by hot water deposition. The original leaves of the Bury species were prepared.

In each of Examples 1 and 2, the total weight, moisture content, dry leaf weight and moisture weight of leaf tobacco for each stage are shown in Table 1 below.

Comparative Example 1

Real xanthoma leaves that were not subjected to hydrothermal treatment were used. The main leaves of the xanth species of Comparative Example 1 were moisture-adjusted so that the moisture content, the dry leaf weight and the total weight were the same as in Example 1.

Comparative Example 2

Non-hydrothermal xanthoma sublobes were used. The sub-leaf of xanthoma of Comparative Example 2 was moisture-adjusted so that the moisture content, dry leaf weight and total weight were the same as in Example 1.

Comparative Example 3

The original leaves of Burberry species that were not subjected to hydrothermal treatment were used. In Comparative Example 3, the main leaves of the burberry species were moisture-adjusted so that the moisture content, dry leaf weight, and total weight were the same as in Example 2.

Comparative Example 4

The sub-leaf of Burry species that were not hydrothermalized was used. The lower leaves of the Bury species of Comparative Example 4 were moisture-adjusted so that the moisture content, the dry leaf weight and the total weight were the same as in Example 2.

Experimental Example 1: Evaluation of leaf weight according to hot water immersion

For the evaluation of leaf weight component modification according to the hot water immersion treatment according to the embodiments of the present invention, the nicotine, ammonia, sugar, nitrate and chlorine contents of each of the leaf cigarettes according to Examples 1 to 2 and Comparative Examples 1 to 4 were analyzed. Table 2 shows.

division Leaf weight component (%) nicotine ammonia temple nitrate Goat xanthoma Comparative Example 1 Main leaf (before immersion) 3.96 LOQ 14.26 0.11 0.53 Example 1 Main leaf (after deposition) 2.43 LOQ 5.78 LOQ 0.22 Comparative Example 2 lower lobe 2.65 0.13 8.61 0.61 1.03 burry species Comparative Example 3 Main leaf (before immersion) 3.32 0.45 0.93 0.63 0.39 Example 2 Main leaf (after deposition) 1.91 0.20 0.49 0.21 0.16 Comparative Example 4 lower lobe 1.94 0.35 0.99 0.87 0.60

Referring to Table 2, it can be confirmed that the leaf weight component of leaf tobacco was modified through hot water deposition. Specifically, when comparing Comparative Example 1 and Example 1, sugar, nitrate (substantially not detected, limit of quantitation; LOQ) and chlorine, which can cause off-flavor components in the main leaves of xanthoma by hot water deposition, were significantly It can be seen that the decrease There was also a slight decrease in nicotine along with the decrease in the above components, but after the decrease, the nicotine content was substantially equivalent to the amount of nicotine in the lower lobe of xanthoma (Dongsanji), which caused a substantial decrease in taste, as will be discussed in the sensory evaluation to be described later. It was confirmed that there was a decrease to the extent that it did not. When comparing Example 1 and Comparative Example 2, the hot-water-immersed xanthoma main leaf had a level of nicotine similar to that of the lower leaf of xanthoma, but lower levels of ammonia, sugar, nitrate and chlorine were lower than that of the lower leaf. .It can be seen that in the case of the burery species, there was a compositional modification in a direction similar to that of the yellow species. Specifically, when comparing Comparative Example 3 and Example 2, it can be seen that ammonia, sugar, nitrate and chlorine, which can cause off-flavor components in the main leaves of Burry species, were greatly reduced by hot water deposition. There was also a slight decrease in nicotine along with the reduction of the above components, but after the decrease, the nicotine content was substantially equal to the nicotine amount of the lower lobe of the Bury species (Dongsanji), which resulted in a substantial decrease in taste, as will be discussed in the sensory evaluation to be described later. It was confirmed that the decrease was not induced. When comparing Example 2 and Comparative Example 4, the hot-water-immersed xanthoma main leaf had a level of nicotine similar to that of the xanthoma lower leaf, but in all of ammonia, sugar, nitrate and chlorine components, lower values were shown compared to the lower leaf. .

Through the above results, it is expected that the leaf tobacco immersed in hot water has less off-flavor and irritation compared to leaf tobacco that is not subjected to heat immersion treatment, and thus the overall tobacco taste is also expected to be supplemented.

Comparative Example 5

Hot water-immersed main leaves were prepared in the same manner as in Example 1, except that the weight of hot water used was about 25 times the weight of leaf tobacco (that is, the weight of hot water used was about 60 kg).

Comparative Example 6

Hot water-immersed main leaves were prepared in the same manner as in Example 1, except that the weight of hot water used was about three times the weight of leaf tobacco (that is, the weight of hot water used was about 9 kg).

Comparative Example 7

The hot water-immersed leaves were prepared in the same manner as in Example 2, except that the weight of hot water used was about 25 times the weight of leaf tobacco (that is, the weight of hot water used was about 60 kg).

Comparative Example 8

The hot water-immersed leaves were prepared in the same manner as in Example 2, except that the weight of hot water used was about three times the weight of leaf tobacco (that is, the weight of hot water used was about 9 kg).
