It can be implemented by the volatilization of, but is not limited thereto.

The binder of the present invention is preferably used as a binder using hydroxypropylmethylcellulose (HPMC), which can be easily combined with natural plant materials and appropriately prepare the size and hardness of natural plant granules, but is not limited thereto. The binder of the present invention may be any one of a hydrophilic polymer, a hydrophobic polymer, a monosaccharide, a disaccharide, a sugar alcohol, or hydroxypropylmethylcellulose (HPMC). Hydrophilic polymers include polyethylene glycol, polyethylene oxide, gelatin, starch, dextran sulfate, sugar, carboxymethylcellulose (CMC), chitosan, hydroxyethylcellulose, hydroxypropylmethylcellulose, methylcellulose, arabinogalactan, and polyvinyl alcohol. , Polyacrylic acid, polyvinylpyrrolidone, gum arabic and sodium alginate one may be selected from the group consisting of. On the other hand, hydrophobic polymers include ethylcellulose, polymers of methacrylic acid and esters thereof, polyethylene, polyamide, hydroxypropylmethylcellulose phthalate, polyethylene vinyl acetate, cellulose nitrate, silicone and poly(lactide-co-glycolic acid). ) May be selected from the group consisting of. Meanwhile, the monosaccharide may be selected from the group consisting of glucose, fructose, tricellulose, and galactose, and the disaccharide may be selected from the group consisting of xylose, D-mannose, sorbose, lactose, and maltose. . In addition, the sugar alcohol may be selected from the group consisting of mannitol, sorbitol, xylitol, glycerin, glycerol and arabitol. The hydroxypropylmethylcellulose (HPMC) binder can be tested under conditions of 2, 15, 20, and 50 cps viscosity, and preferably, a binder having a viscosity of 50 cps is used.

At this time, the content of the binder binding to the natural plant material is 1 to 5%, preferably 2%, so that the weight ratio of the natural plant material and the binder is 98%: 2%. On the other hand, in order to improve the adsorption ability during the manufacture of the binder, it can be prepared by adding extracts of various natural plants, and the alcohol concentration for extracting the extract may be 0 to 100%, and preferably 50% alcohol concentration is used. . Meanwhile, in order to increase the moldability of the natural plant granule powder, an inorganic binder selected from silica, silicate, and bentonite may be further added in a weight ratio of 1 to 30% with respect to the natural plant material. On the other hand, by preparing the natural plant granules as wet or dry granules and adding them to the filter, the natural plant scent can be uniformly transferred from the beginning to the end during smoking.

The form of natural plant granules is preferably prepared in wet and dry granules, but may include extracts, capsules, and mixtures.

The natural plant granules have a size of 0.25 to 2.0 mm, and preferably 0.5 to 1.0 mm. At this time, if the size of the prepared natural plant granules is smaller than 0.25 mm, the degree of scattering (flying) of the granules increases during the manufacture of the tobacco filter, causing filter contamination. Conversely, if the size of the natural plant granules is larger than 2.0 mm, When adding granules into the tobacco filter, it is difficult to add a certain amount, so that it may be difficult to ensure uniformity of the quality of the tobacco filter.

The moisture content of the natural plant granules made under optimal granulation conditions is 5 to 12%, preferably 7 to 10% of the total weight of the natural plant granules, and is put into the tobacco filter. If the moisture content of the granules is outside the above range, a phenomenon in which the granules are crushed may occur, and a filter contamination problem may be caused by the crushed fine powder. Therefore, both the productivity and quality of the tobacco filter to which granules are applied may be deteriorated.

It is preferable that the hardness of natural plant granules is 90.0 to 99.0%. When using a hydroxypropylmethylcellulose (HPMC) binder having a viscosity of 98%: 2% and 50 cps by weight of the natural plant material and the binder, the hardness of the natural plant granules may be 90.0 to 99.0%. In this case, the granules applied to the tobacco filter are not broken or deformed, and the amount of granules to be added to the tobacco filter may be added. On the other hand, when the amount of granules added to the tobacco filter is 3 mg/mm Tip, the maximum scent can be expressed, and the workability efficiency of applying the granules to the filter can also be improved.

The present invention relates to a tobacco filter comprising a filter unit for accommodating natural plant granules, characterized in that the natural plant granules are not added to the tobacco cut filler, but added to the tobacco filter unit. In the conventional method of adding tobacco to the cuticle, the natural plant scent is transformed by thermal decomposition or synthesis when the cigarette is burned to cause a bad odor (irritation, fish, burnt, spicy, sulfur, eggs). Since natural plant granules are added only to the cigarette filter part, not the chobu, the original flavor of the natural plant is delivered to the smoker without being deformed by pyrolysis or synthesis.

Meanwhile, the tobacco filter of the present invention may be a tobacco filter further including herbal oil capsules containing oil components extracted from natural plant materials. Thereby, it is possible to provide a tobacco filter with enhanced natural plant fragrance and enhanced fragrance retention. Herb oil capsules can be used extracted from natural plant materials such as pine needles and rosemary.

Tobacco Characteristic Experiment

It was confirmed that the tobacco prepared in Example 24-1 had the following characteristics.

Analysis of scent component transition related to bad breath reduction in cigarette smoke

Using the tobacco prepared in Example 24-1, an experiment was conducted to analyze the migration of fragrance components in smoke of pine needles and rosemary.

Using the solid phase microextraction (SPME) method, an experiment was conducted to confirm the fragrance components of pine needles and rosemary and their smoke.

For the extraction of fragrance components from the smoke of pine needles and rosemary, SPME fiber (PDMS/DVB) to be applied to 0.5 g of each sample of pine needles and rosemary was heated at 80 °C and extracted for 30 minutes. Sample pretreatment was performed for 5 minutes for fiber adsorption and 3 minutes for fiber desorption. On the other hand, fiber includes, but is not limited to, PA (polyacrylate), PDMS (polydimethylsiloxane), CAR (Carboxen)/PDMS, or PDMS/DVB (Divinylbenzene), and in this experiment PDMS/DVB (Divinylbenzene) Was used. Fiber was injected into GC-MS (GC-MS in which agilent's 5973 MSD system and 5975C inert XL mass spectrometer are linked) using GERSTEL's MPS (Multi Purpose Sampler).

The analysis of the migration of fragrance components in smoke of pine needles and rosemary was carried out by a method of quantitative analysis after sample pretreatment of pine needles and rosemary. In the sample pretreatment process, 20 cigarettes (Smoking Cigarette) and 44 mm filter pads were used. Tobacco smoke was collected on a Cambridge filter pad using dry ice, an impinger was connected, extracted alternately with 20 ml methanol (MeOH) for 1 hour, and then filtered through a 0.45 μm PVDF filter.

Next, the pretreated sample was quantitatively analyzed by GC/MS, SIM mode analysis method.

As a result of the experiment, the odor transfer components in the smoke of pine needles were Borneol, Bonyl acetate, 1,8-Cineol (1,8-cineol), Delta- cardian (δ- cadinene), Alpha-cardi. It was found to contain components of ophthalmic ( α- cadinene), limonene, and benzaldehyde. The fragrance transition components of rosemary smoke include Borneol, Bonyl acetate, 1,8-Cineol (1,8-cineol), Beta-Caryophyllene, and Alpha-Humulene. -Humulene), delta-terpineol (δ-Terpineol), and alpha-terpineol (α-Terpineol) components were found to be included (see Fig. 6).

Agilent's DB-Wax column (length 30m, ID 0.25 ㎜, film thickness 0.25 ㎛) was used for the efficient separation of the scent components in the smoke of pine needles and rosemary when quantitatively analyzing the scent components in smoke, and helium gas, an inert gas, was used as a carrier. It was used as gas. The flow rate was 1 ml/min, and the sample was injected into the instrument at an injection temperature of 250°C in a splitless mode.

The temperature program of GC-MS was set in order to detect the scent components in the smoke of pine needles and rosemary, starting with maintaining at 35℃ for 10 minutes, raising the temperature to 100℃ at a rate of 2℃/min, and then 1 The temperature was raised to 200°C at a rate of °C/min, and elevated to 230°C at a rate of 3°C/min to maintain the temperature for 10 minutes. The separated component enters the MS along the helium gas, and to detect this, the ion source was set to 250℃, the transfer line was 240℃, and the quadrupole was set to 150℃. For ionization energy, 70 eV, which is commonly used in electron impact (EI), was used.

After manufacturing a cigarette containing a tobacco filter to which the natural plant material pine needles and rosemary granules were applied, the scent components of pine needles and rosemary were analyzed using cigarettes 90 days elapsed (see Fig. 7). As a result of the experiment, the migration of some components of pine needles and rosemary was confirmed and shown in Table 5 below. Therefore, when a cigarette containing a tobacco filter to which pine needles and rosemary granules were applied was manufactured, the possibility of expressing natural scent and imparting functionality could be confirmed.

Pine needles and rosemary powders, granules, oils, flavoring solutions, as well as pine needles, among the smoke-transferring components, are alpha-pinene, bonyl acetate, and rosemary 1,8-cineol (1,8- Cineol), Borneol (Borneol) was added to a cigarette filter, and a cigarette containing the same was prepared to confirm the ability to reduce methyl mercaptan.

Methyl mercaptan was 1ppm [1㎍/㎖] 2mL, and when using pine needle and rosemary powder and granules, 10mg sample was extracted with 2mL of water and used. On the other hand, when using pine needle and rosemary oil and flavoring solution, 2 ml was used, and as a single component, 3 ppm (3 µg/ml) of a sample was extracted with 2 ml of water and used.

The analysis of the reduction ability of methyl mercaptan was carried out by dividing the sample pretreatment process, the headspace sampler condition, and the analysis process under GC/MS-SIM conditions. First, 10 mg of pine needle and rosemary powder and granule samples were put in a 20 ml vial, and immersed in 2 ml of water for 1 hour. Next, 2 ml of 0.2M Potassium phosphate was added, and the pH was adjusted to 7.5. Thereafter, 2 ml of methyl mercaptan (1µg/ml) was added and sealed, followed by stirring with a Vortex mixer for 5 seconds. The reaction was carried out at 42° C. for 6 minutes in a headspace sampler, and methyl mercaptan released in the headspace was directly analyzed by GC/MS. The reduction rate was measured by comparing the area of methyl mercaptan obtained as a result of GC/MS analysis with the control.

Confirmation of the effect of reducing bad breath substances

Using the tobacco prepared in Example 24-2, an experiment was conducted to identify volatile sulfur compounds (VSCs), which are the major causative substances that cause bad breath.

The main component of bad breath are volatile sulfur compounds (VSCs), and smoking causes the concentration of VSCs in the mouth to rise. The amount of volatile sulfur compounds transferred into the smoke is around 1%, but the threshold value is very low and the odor characteristics are irritating due to rotten onion and garlic scents.

Hydrogen sulfide (H ₂ S) and methyl mercaptan (MM, Methyl mercaptan) were designated as analysis indicators to analyze halitosis-causing substances. The halitosis capture group included a total of 30 smokers in the group who consumed Reson Black cigarettes. As for the halitosis collection method, one cigarette for each product was smoked, and after smoking for 2 minutes at 30-minute intervals, bad breath was collected (Tedlar Bag, 3L). The halitosis analyzer includes a thermal adsorption and desorption system (TD-GC/MS) and a Pursed Frame Photometric Detector (PFPD); TD/GC-PFPD conforming to the odor process test standard (notified by the National Institute of Environmental Sciences) was used.

As a result of the experiment, hydrogen sulfide (H ₂ S) was detected at a concentration below the threshold. On the other hand, methyl mercaptan, a bad breath-causing component, was confirmed to have a reduced effect in a tobacco filter to which natural plant materials (rosemary and pine needles) were applied. In particular, when rosemary extract and rosemary oil capsule were applied, methyl mercaptan was reduced by 67.4%, showing the highest reduction effect, and when pine needle extract and pine needle oil capsule were applied, the effect was reduced by 30.7% ( See Table 16).

Safety evaluation of tobacco applied with natural plant materials

The safety of tobacco products to which natural plant materials pine needles and rosemary were applied was verified using the tobacco prepared in Example 24-1.

Review criteria

This natural plant material has no safety issues of the substance itself and is applied to non-burning areas, but unlike chemical substances composed of a single substance, the composition is unclear and there are no cases of using tobacco for the same purpose. Therefore, it was reviewed in accordance with the in-house evaluation criteria for the safety evaluation of additives for non-combustion tobacco materials.

Basic information evaluation

The basic information of the natural plant material pine needles and rosemary was evaluated. These two natural plant materials are listed on the KFDA's list of usable food ingredients, and no toxic information such as carcinogenicity or reproductive toxicity has been reported for the raw material itself. In addition, there are no domestic and foreign regulations on the allowable amount of use, and there are no examples of cigarettes used by major competitors and companies. However, it was confirmed that “Pine Needle oil” and “Rosemary oil” extracted from pine needles and rosemary were used.

Smoke component contribution evaluation

The contribution of the tobacco smoke component to which the natural plant material was applied was evaluated through the purge & trap analysis method. As a result, the toxicity information is insufficient except for the two ingredients of rosemary and one ingredient of pine needles registered as food additives of the USFDA, the concentration is high (>5 ppm), and the ingredient does not exist in tobacco smoke, so the contribution to biological activity is evaluated. Was determined to be required.

Biological activity evaluation

The biological activity of the tobacco smoke component to which the natural plant material was applied was evaluated. As a result of comparing and analyzing the effects of cell function and genetic function in the control group (product without granules) and the test group (product with granules), there was no significant difference (P<0.05) between the two samples. Therefore, it could be determined that the two types of granules had no effect on the increase or decrease of biological activity. The results of the Ames test of the mainstream lead solid phase fraction (TPM) and the results of evaluating the cellular function effect of the mainstream lead solid phase fraction (TPM) are shown in FIG. 10 (see FIG. 10).

Natural plant materials of pine needles and rosemary are substances recognized as food raw materials (KFDA), and are limitedly applied to non-burning areas of tobacco, and individual ingredients are also present in low concentrations of 5 ppm or less, and the contribution of tobacco smoke to the biological activity Since it is at a negligible level, it was judged that it can be used in filters at the current usage level when viewed comprehensively.

Evaluation of storage properties of tobacco applied with natural plant materials

Using the tobacco prepared in Example 24-1, the storage properties of the tobacco product to which the natural plant material pine needles and rosemary were applied were verified.

An experiment was conducted for the purpose of determining the life cycle according to the application of natural plant material granules to tobacco products. Natural plant material granules 3mg/mm Tip were applied in the tobacco filter, and the experimental conditions were divided into dry season and rainy season. In the case of dry weather conditions, the temperature was set to 15°C and humidity of 45% RH, and in the case of the rainy season, the temperature was set to 25°C and humidity of 59% RH. The tobacco product of Example 24-1 was prepared, and after 1 month, no problems were found in the change in the moisture content of the tobacco product and the shape of the product, and no change in microorganisms was observed, so that the corresponding natural plant material granules were applied. The storability of could be verified.
