JP7164097B2 - Functional cigarette filter containing natural plant material, tobacco, and method for producing the same - Google Patents

Description

TECHNICAL FIELD The present invention relates to a natural plant material-containing cigarette filter that reduces tobacco-derived odor components and oral malodor-inducing substances, a cigarette containing the same, and a method for producing the same.

Generally, to produce tobacco, various types of leaf tobacco are first blended and processed to obtain the desired aroma and flavor. The processed tobacco is then cut into cigarette fillers and wrapped with cigarette paper to produce filterless cigarettes. Filters are then attached to unfiltered cigarettes as needed.

Cigarettes are one of the representative luxury goods, and consumers obtain various satisfactions through smoking. In particular, studies on adding natural plant materials to tobacco have been actively conducted so that consumers can enjoy the scent of natural plant materials they like while smoking. In addition, since the smell of tobacco that remains in the mouth and hands of smokers after smoking gives a negative perception to those around them, research on cigarettes that do not leave the smell of tobacco and its manufacturing method is actively conducted. It is done.

For example, through the chemical, antibacterial, and masking effects of volatile substances of natural plant materials, it is possible to confirm the effect of reducing halitosis components in the oral cavity by transferring volatile components into smoke. Here, the gas molecules fly at a speed of 100 to 1,000 m/s, and collide with other molecules about 20,000 times or more while traveling 1 mm, so that the above effect can be obtained. In addition, by using the chemical and adsorption action of non-volatile substances of natural plant materials, it is possible to expect the effect of reducing halitosis-inducing components derived from tobacco. Therefore, there is a need for an optimized method for applying natural plant materials to cigarette filters to reduce tobacco-derived odor components and oral halitosis-causing substances.

The natural plant material processed in the present invention can be applied singly or in combination as long as it is an acceptable plant under the Food Additives Act, and among the plant parts, it contains the most natural fragrance components. The parts (for example, leaves, stems, roots, fruits, etc. selected and used) can be used after being processed so that the natural state or its material is suitable for application to product tobacco.

In the following examples, pine needles and rosemary were selected as natural plant materials, and their components and effectiveness were analyzed.

When the pine needle and rosemary natural plant material of the present invention is applied as a cigarette filter, it can be confirmed that it has the effect of reducing bad breath components derived from tobacco and increasing the expression of natural plant flavor. The effect of reducing bad breath components derived from tobacco can be realized by chemical neutralization of terpenes volatile aroma components, chemical action of polyphenol aroma components, and physical adsorption by granule porous and dietary fiber. Although the effect of increasing the flavor expression of can be realized as a volatilization action of the volatile fragrance component, it is not limited to this.

The binder of the present invention is preferably, but not limited to, hydroxypropylmethylcellulose (HPMC), which easily binds to natural plant materials and can produce natural plant granules with appropriate size and hardness. never The binders of the present invention may be any one of hydrophilic polymers, hydrophobic polymers, monosaccharides, disaccharides, sugar alcohols, hydroxypropylmethylcellulose (HPMC). Hydrophilic polymers include polyethylene glycol, polyethylene oxide, gelatin, starch, dextran sulfate, sugar, carboxymethylcellulose (CMC), chitosan, hydroxyethylcellulose, hydroxypropylmethylcellulose, methylcellulose, arabinogalactan, polyvinyl alcohol, polyacrylic acid, polyvinylpyrrolidone. , gum arabic and sodium alginate. On the other hand, hydrophobic polymers include ethylcellulose, polymers of methacrylic acid and their esters, polyethylene, polyamide, hydroxypropylmethylcellulose phthalate, polyethylene vinyl acetate, cellulose nitrate, silicon and poly(lactide co-glycolic acid) (poly( One may be selected from the group consisting of lactide-co-glycolic acid)). On the other hand, monosaccharides are selected from the group consisting of glucose, fructose, tricellulose and galactose, and disaccharides are xylose, D-mannose, sorbose, lactose and maltose. One may be selected from the group. Moreover, one sugar alcohol may be selected from the group consisting of mannitol, sorbitol, xylitol, glycerin, glycerol and arabitol. Said hydroxypropyl methylcellulose (HPMC) binder is tested under conditions of 2, 15, 20, 50 cps viscosity, preferably 50 cps viscosity binder is used.

Here, the content of the binder that binds with the natural plant material is 1-5%, preferably 2%, and the weight ratio of the natural plant material and the binder is 98%:2%. On the other hand, in order to improve the adsorption capacity during the preparation of the binder, it can be prepared by adding various natural plant extracts, and the alcohol concentration for extracting the extract may be 0 to 100%. , preferably with an alcohol concentration of 50%.

Forms of natural plant granules are preferably prepared as wet and dry granules, but may also include forms of extracts, capsules and mixtures.

The size of the natural plant granules is 0.25-2.0 mm, preferably 0.5-1.0 mm. Here, if the size of the produced natural plant granules is smaller than 0.25 mm, the degree of scattering of the granules increases during the production of the cigarette filter, causing filter contamination. If the size is larger than 2.0 mm, it is difficult to put a certain amount of granules into the cigarette filter, which may lead to a problem that it is difficult to ensure the uniformity of the quality of the cigarette filter.

Moisture content of the natural plant granules produced under optimal granulation conditions is 5-12%, preferably 7-10%, based on the total weight of the natural plant granules, and is put into the cigarette filter. . If the moisture content of the granules is outside the above range, the granules may become fragile, and the broken fines may cause filter contamination problems. Consequently, the productivity and quality of cigarette filters to which the granules are applied are all reduced.

The hardness of the natural plant granules is preferably 90.0-99.0%. When the weight ratio of natural plant material and binder is 98%:2% and hydroxypropyl methylcellulose (HPMC) binder with 50 cps viscosity is used, the hardness of natural plant granules is manufactured to 90.0-99.0%. good too. In this case, the granules applied to the cigarette filter are not broken or deformed, and the desired amount of granules can be added to the cigarette filter. On the other hand, when the amount of granules put into the cigarette filter is 3 mg/mmTip, the maximum flavor can be expressed and the efficiency of applying the granules to the filter is enhanced.

The present invention relates to a cigarette filter including a filter part containing natural plant granules, characterized in that the natural plant granules are added to the tobacco filter part without being added to the shredded part of the tobacco. The conventional method of adding to the cut portion of tobacco is that when tobacco is burned, the aroma of natural plants is transformed by thermal decomposition and synthesis, resulting in unpleasant odors (irritant, fishy, burnt, pungent, sulfur, egg). On the other hand, in the present invention, natural plant granules are added only to the tobacco filter portion, not the cut portion of the tobacco, so that the original flavor of natural plants can be smoked without being deformed by thermal decomposition or synthesis. will be communicated to the person.

Tobacco Characteristic Test It was confirmed that the tobacco produced in Example 24-1 had the following characteristics.

Analysis of Fragrance Component Transfer Related to Halitosis Reduction in Cigarette Smoke Using the tobacco produced in Example 24-1, a test was conducted to analyze the aroma component transfer in smoke of pine needles and rosemary.

Using a Solid phase microextraction (SPME) method, pine needles and rosemary were tested to identify the scent components in their respective smokes.
For the extraction of aroma components from smoke of pine needles and rosemary, SPME fibers (PDMS/DVB) applied to 0.5 g samples of each of pine needles and rosemary were heated at 80° C. and extracted for 30 minutes. A sample pretreatment process 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). (Divinylbenzene) was used. The fiber was injected into a GC-MS (a GC-MS coupled with an Agilent 5973MSD system and a 5975Cinert XL mass spectrometer) using a GERSTEL MPS (Multi Purpose Sampler).

In the pine needle and rosemary smoke, the migration analysis test of the aroma component was tested by a quantitative analysis method after pretreatment of the pine needle and rosemary sample. Twenty Smoking Cigarettes and a 44 mm filter pad were used during sample pretreatment. Tobacco smoke was captured on a Cambridge filter pad using dry ice, connected to an impinger, extracted alternately with 20 ml methanol (MeOH) for 1 hour, and then filtered through a PVDF filter with a pore size of 0.45 μm.

Next, the pretreated sample was quantitatively analyzed by GC/MS, SIM mode analysis method.
As a result of the test, among the pine needle smoke, the scent-transferring components were borneol, bornyl acetate, 1,8-cineol (1,8-cineol), delta-cadinene (δ-cadinene), alpha- It was confirmed that it contained cadinene, limonene, and benzaldehyde. Among rosemary smoke, aroma-transferring components are Borneol, Bornyl acetate, 1,8-Cineol (1,8-cineol), beta-caryophyllene (β-Caryophyllene), alpha-humulene (α -Humulene), delta-terpineol (δ-Terpineol), and alpha-terpineol (α-Terpineol) components were confirmed (see FIG. 6).

A DB-Wax column (length 30 m, ID 0.25 mm, film thickness 0.25 μm) manufactured by Agilent was used to efficiently separate the scent components from the pine needle and rosemary smoke during quantitative analysis of the scent components in the smoke. and helium gas, an inert gas, was used as the carrier gas. The flow rate was 1 ml/min and the sample was injected into the instrument in a splitless mode with an injection temperature of 250° C. after injection.
In order to detect the aroma components in the smoke of pine needles and rosemary, a GC-MS temperature program was set, starting with holding at 35 ° C. for 10 minutes, and increasing the temperature to 100 ° C. at a rate of 2 ° C./min. The temperature was raised again at a rate of 1°C/min to 200°C, and then raised to 230°C at a rate of 3°C/min and held for 10 minutes. The separated components enter the MS along with the helium gas, and the ion source was set at 250°C, the transfer line at 240°C, and the quadrupole at 150°C for detection. An ionization energy of 70 eV, which is commonly used in electron impact (EI), was used.

After 90 days from the manufacture of cigarettes including cigarette filters to which pine needles and rosemary granules, which are natural plant materials, were used, aroma components of pine needles and rosemary were analyzed (see FIG. 7). As a result of the test, it was confirmed that some components of pine needles and rosemary were transferred to the smoke, and the results are shown in Table 5 below. Therefore, it was possible to confirm the possibility of expressing natural flavor and imparting functionality when producing a cigarette including a cigarette filter to which pine needles and rosemary granules, which are natural plant materials, are applied.

Confirmation of Halitosis-Inducing Substance Reduction Effect Using the tobacco produced in Example 24-1, a test was conducted to confirm the halitosis-reducing ability of methyl mercaptan, a representative halitosis component in tobacco smoke. .
Pine needles and rosemary powders, granules, oils, flavoring liquids, as well as, in the case of pine needles, among the smoke transfer components, alpha-pinene, Bonyl acetate, rosemary, 1, 8-Cineol (1,8-Cineol) and Borneol were added to cigarette filters, and cigarettes containing them were produced to confirm the ability to reduce methyl mercaptan.

Methyl mercaptan was used after extracting 10 mg of sample with 2 ml of water when pine needles and rosemary powders and granules were used, using 2 ml of 1 ppm [1 μg/ml]. On the other hand, when pine needle and rosemary oil and flavoring liquid were used, 2 ml of the single component was used after extracting 3 ppm (3 μg/ml) of the sample with 2 ml of water.

Methyl mercaptan component reduction ability analysis test was performed by classifying into sample pretreatment process, Headspace Sampler condition and GC/MS-SIM condition. First, 10 mg of pine needles and rosemary powder and granules were placed in a 20 ml vial and immersed in 2 ml of water for 1 hour. Next, 2 ml of 0.2 M Potassium phosphate was added to adjust the pH to 7.5. After that, 2 ml of methyl mercaptan (1 μg/ml) was added, sealed, and stirred for 5 seconds with a Vortex mixer. The mixture was reacted in a Headspace Sampler at 42° C. for 6 minutes, and methyl mercaptan liberated in the Headspace was directly analyzed by GC/MS. The area of methyl mercaptan obtained from the GC/MS analysis results was compared with the control plot to measure the reduction rate.

· C: Area of methyl mercaptan in control group · S: Area of methyl mercaptan in test group - Tokita, F.; et al. See Nippon Nogeikagaku Kaishi 586, p585-589 [1984].

The instrumental analysis conditions for GC/MS were set as follows for testing. The conditions of the Headspace Sampler were set to a culture temperature of 42°C, a culture time of 6 minutes, and a transfer liner temperature of 100°C.
The conditions for GC/MS-SIM were Oven Temp. Applied at 35°C for 10 minutes, Post run at 250°C for 30 minutes. Injector/Interface Temp. was applied at 150° C. or 220° C., Injection was Split 10:1, Flow rate 1 ml/min, methyl mercaptan ion (m/z) was tested by applying 47 quantitative ions and 48 and 45 qualitative ions.

Pine needles and rosemary powder, granules, oil, filter flavoring liquid, Cineol, Bonyl acetate, and Borneol, which are scent-transferring components in smoke, are applied as cigarette filters to obtain methyl mercaptan ( Methyl mercaptan) was confirmed and shown in Table 6 below (see FIG. 8). On the other hand, as a result of the test, the methyl mercaptan reduction ability of the cigarette attached to the filter to which pine needles and rosemary were applied was confirmed, but due to the difference in smoking amount, the direct analysis of cigarettes was limited to detection. was there.

Measurement of sedimentation degree of halitosis components through absorption analysis Using the tobacco produced in Example 24-1, the sedimentation degree of halitosis components was measured through absorptiometry, and a filter applied with pine needles and rosemary was attached. A test was conducted to confirm the ability to reduce halitosis components derived from oral microorganisms in tobacco.

In the halitosis component sedimentation test, among the volatile sulfides, which are halitosis components generated when salivary oral bacteria are cultured, hydrogen sulfide is combined with the iron component in a liquid state, and the black color of iron sulfide (FeS) is obtained. By binding to the morphology of the sediment, the sedimentation rate of halitosis components was compared and carried out. First, whole saliva was cultured at 37° C. under anaerobic conditions for 48 hours. Then, 0.5 ml of cultured saliva was loaded with 50 ml of oil test substance or 20 ul of single component test substance, 0.05 g of surfactant was added, followed by 0.05 g of ferrous sulfate (FeSO4). were mixed. After culturing this at 37° C. under anaerobic conditions for 24 hours, the absorbance was measured at 700 nm to confirm the degree of sedimentation of halitosis components.

Pine needle and rosemary oil, perfume liquid, alpha-pinene, 1,8-cineol, 1,8-cineol, borneol (bonyl acetate), borneol ( Borneol) was applied to a cigarette filter to confirm the ability to reduce halitosis components, and the results are shown in Table 7 below (see FIG. 9). On the other hand, as a result of the test, it was confirmed that the cigarette attached with the filter applied with pine needles and rosemary had the ability to reduce halitosis components derived from oral microorganisms. There was a limit of detection.

Ability to Reduce Odor and Toxic Components in Cigarette Smoke A test was conducted to confirm the ability to reduce odor and toxic components in tobacco smoke using the cigarettes produced in Example 24-1.

3 mg/mm Tip of each rosemary and pine needle granules were applied to cigarette filters and tested. Ammonia, acrolein, crotonaldehyde, methyl ethyl ketone (MEK), 1,3-butadiene were measured as a result of measuring the reduction rate (%) of odorous components and toxic components per tar in smoke. A 9-55% reduction in (1,3-butadiene), acrylonitrile, benzene, and pyridine components was observed. On the other hand, the carbonyl components contained in the tar that cause tobacco smell include acrolein, crotonaldehyde, and methyl ethyl ketone (MEK), and the volatile organic compound is 1,3-butadiene ( 1,3-butadiene), acrylonitrile, and benzene. A non-volatile organic compound component is pyridine.

Table 8 shows the results of analysis of the ability to reduce odor and toxic components in filter-attached cigarette smoke to which pine needles and rosemary granules were applied.

Confirmation of Cigarette Smoke Components The tobacco smoke components produced in Example 24-2 were analyzed.
Test results It was confirmed that smoke components in the control plot and the test plot were on the same level (see Table 15).

Confirmation of Effect of Reducing Halitosis Inducing Substances Using the tobacco produced in Example 24-2, a test was conducted to confirm volatile sulfide compounds (VSCs), which are the main causative substances inducing halitosis.
The main components of halitosis are volatile sulfides (VSCs), and smoking causes an increase in the concentration of VSCs in the mouth. Although the amount of volatile sulfides transferred in the smoke is around 1% level, the threshold is very low and the odor characteristics are pungent like rotten onions and garlic.

Hydrogen sulfide (H ₂ S) and methyl mercaptan (MM) were designated as analytical indicators to analyze halitosis-inducing substances. The oral malodor collection group included a total of 30 smokers from the RAISON BLACK tobacco consumption group. As for the halitosis collection method, one cigarette was smoked for each product, and halitosis was collected after smoking for 2 minutes at intervals of 30 minutes (Tedlar Bag, 3L). The halitosis analyzer is a thermal adsorption/desorption system (TD-GC/MS) and PFPD (Pursed Frame Photometric Detector), and a TD/GC that conforms to the offensive odor process test standards (announced by the National Institute of Environmental Science). - Utilized PFPD.

As a result of the test, hydrogen sulfide (H ₂ S) was detected at a concentration below the threshold. On the other hand, it was confirmed that a cigarette filter to which natural plant materials (rosemary and pine needles) were applied reduced methyl mercaptan, which is a bad breath-inducing component. In particular, when rosemary extract and rosemary oil capsules were applied, methyl mercaptan decreased by 67.4% and had the highest reduction effect, and pine needle extract and pine needle oil capsules were applied. In the case, there was a 30.7% reduction effect (see Table 16).

(See Table 17).

Analytical Test of Odorous and Toxic Components in Cigarette Smoke Reduction rate (%) per tar of odorous and toxic components transferred in mainstream cigarette smoke produced in Example 24-2 was confirmed. Odor and toxicity in cigarettes containing filters added with rosemary extract and rosemary oil capsules (RE + RC), pine needle extract and pine needle oil capsules (PE + PC), which are highly effective in reducing methyl mercaptan in Table 16 The effect of reducing components by 12.4-29.2% was confirmed (see Table 18).

Safety Evaluation of Tobacco Using Natural Plant Materials Using the tobacco produced in Example 24-1, the safety of tobacco products to which pine needles and rosemary, which are natural plant materials, were applied was verified.

Examination Criteria The natural plant material in question has no safety issues of its own and is applied to non-combustible parts. There are no cases of tobacco use in Therefore, the study was conducted according to the In-house evaluation criteria for additive safety evaluation of non-combustible tobacco materials.

Evaluation of basic information Basic information of the natural plant materials, pine needles and rosemary, was evaluated. The two natural plant materials are listed in the KFDA's list of usable food ingredients, and toxicity information such as carcinogenicity and reproductive toxicity for the ingredients themselves has not been reported. In addition, there are no domestic or international regulations on the permitted amount of use, and there are no cases of its use in cigarettes by major competitors or by the company itself. However, it was confirmed that "Pine Needle oil" and "Rosemary oil" extracted from pine needles and rosemary were used.

Contribution Evaluation of Smoke Components Contribution of tobacco smoke components to which the relevant natural plant material was applied was evaluated by the Purge & Trap analysis method. As a result, it was found that the toxicity information was inadequate for the two components of rosemary and one component of pine needles registered as food additives by the USFDA, and that they had a potentially high concentration (>5ppm) and did not exist in tobacco smoke. Therefore, it was determined that evaluation of contribution to biological activity is required.

Biological activity evaluation Tobacco smoke components to which the natural plant material of interest was applied were evaluated for biological activity. A comparative analysis of the effects of cellular and genetic functions on the control group (product without granules) and test group (product with granules) showed no significant difference (P<0.05) between the two samples. Therefore, it can be judged that the two types of granules do not affect the increase or decrease in biological activity. FIG. 10 shows the results of the Ames test for solid phase fractionation (TPM) of mainstream smoke and the evaluation results of the effect of solid phase fractionation (TPM) of mainstream smoke on cellular functions (see FIG. 10).

Pine needles and rosemary natural plant materials are substances approved as food raw materials (KFDA), are applied restrictively to the non-burning parts of tobacco, and individual components are also present as low concentrations of 5 ppm or less, and smoke smoke Because of the negligible level of contribution to the biological activity of , it was determined that, overall, it can be used as a filter at the current usage level.
