A tobacco for containg menthol and method of the cobacco}

The present invention relates to a cigarette containing menthol (Menthol) and a method for manufacturing the same, and more particularly, it is possible to shorten the storage time by shortening the time required until the menthol contained in the cigarette reaches an equilibrium, Cigarettes containing menthol and its manufacture, which can be uniformly transferred to mainstream smoke to allow smokers to feel a constant and uniform menthol scent during smoking, and to increase the shelf life of menthol and increase the quality of tobacco. It is about a method.

Traditionally, peppermint scent is a fragrance substance widely used in human life after vanilla and orange, and is added to various foods and industrial products because of its freshness and cleanness as well as to enhance the mood of inhalers. In particular, the peppermint flavor is widely used in various fields because it can be widely used by both young and old without being biochemically restricted.

The main ingredient of peppermint flavor is menthol, which has 8 isomers, including (-)-menthol {(-)-menthol}. Among them, (-)-menthol has excellent excitatory effect, thus preparing oral protection. It is used in various fields such as cigarettes, cigarettes, sweets and spices. In particular, the biochemical stability of menthol added to cigarettes, foods, or flavors is approved by the FDA for direct use as a food additive, and has been reported to have no problems with other carcinogenic, genotoxic, metabolic or environmental toxicities. There is a bar.

Menthol having such physicochemical properties and stability is widely used in the tobacco field. As is well known, menthol is added in the process of manufacturing tobacco to give a smoker a fascinating fragrance and a fresh taste that seems somewhat irritating. . In this regard, various techniques are known for producing tobacco containing menthol.

US Pat. No. 1,555,580 discloses a technique for dissolving menthol and cassia oil in alcohol and spraying it on tobacco. US Pat. No. 2,565052 sprays mixed flavor solution in which menthol is dissolved onto leaf tobacco and filters. Disclosed is a technique. In addition, US Patent No. 2,969,795 discloses a technique for spraying tobacco with a mixture solution obtained by adding menthol to a mixture of glycerin and organosilicon, and EPO 140,679 discloses menthol in water and water. Disclosed is a technique for spraying a cigarette by stirring at high speed. In addition, U.S. Patent No. 3,548,838 discloses a technique for spraying a ethanol solution in which menthol is dissolved by attaching a nozzle to a venturi tube portion through which a cigarette passes.

In addition, U.S. Patent No. 4,243,056 discloses a technique in which a liquid carbonic acid is mixed with menthol and swelled during carbonic acid gas swelling of leaf tobacco to be included in tobacco. In addition, U.S. Patent No. 3,817,258 discloses a technique of directly spraying the winding part to manufacture a cigarette by directly injecting a mixed solution of alcohol and menthol through a nozzle in the suction belt before being transferred to the garniture portion of the hoisting machine. In addition, US Patent No. 4,995, 405 proposes a method of spraying menthol to the suction belt, that is, the area where the tobacco accumulates to form a winding tube.

Unlike the previous technologies, as a technology considering the bonding side of the filter and menthol or the bonding side of the additive and menthol, US Patent No. 3,066,347 proposed a method of expressing menthol flavor by combining menthol to filter paper, and US Patent No. 4,123,592 The patent discloses a technique for impregnating cellulose fibers in ammonia and menthol solutions to evaporate ammonia and then include menthol physically encapsulated within the cellulose substrate. In addition, U.S. Patent No. 5,144,967 and U.S. Patent No.951,510 disclose a technique in which menthol is penetrated into activated carbon or molecular sieve to be added to cigarette paper, or a cigarette paper containing menthol is installed to deliver menthol flavor to smokers during combustion. It is starting. In addition, U.S. Patent Nos. 4,889,144 and Swiss Patent 648,733 disclose a technique in which a foam capsule including menthol is formed and installed inside the filter to release the fragrance by releasing pressure, and U.S. Patent No. 3,236,244 and U.K. 1,382,476 discloses a technique for mixing menthol with carbon particles and allowing them to bind inside the filter of a cigarette. In addition, U.S. Patent No. 3,500,598 saturates menthol in gum arabic or gelatin to form capsules that can be destroyed by heat with a diameter of 5-40 microns and dispersed in tobacco leaves or leaflets. A method is proposed, US Pat. No. 4,253,473 discloses that menthol is physically combined with hydroxyproply cellulose, gelatine, dextrin or acacia sap, and then dispersed into a cigarette to smoke. The transition of menthol to mainstream smoke has occurred, and US Pat. No. 5,144,966 discloses a method of incorporating a fibrous impregnated aroma material into the winding portion of a cigarette.

In addition, there are known techniques for adding a compound to be combined with a menthol component and then separating and performing it in smoking. As a related art, US Pat. No. 63,111,127 discloses a compound added as methyl esters (monomethyl maleates, succinnates). , phthalates, etc.) and organic keto acids and other esters are disclosed. US Pat. No. 3,499,452 describes carbonate ethers, and US Pat. No. 4,002,179 discloses polymeric carbonate ethers. carbonate ethers) are disclosed.

On the other hand, Korean Patent No. 88554 has attempted to improve the retention of menthol fragrance by improving the retention of menthol fragrance by absorbing menthol in activated carbon and inserting it in a cigarette filter. No. 23472 relates to a device for applying a flavourant or menthol, and has been proposed for a device for directly spraying cigarette tobacco onto a lower suction band in a hoist through a nozzle orifice.

In addition to the above-described techniques, various techniques are known for manufacturing menthol-containing tobacco by adding menthol in the process of manufacturing tobacco. However, the problem to be solved in common in the menthol tobacco manufactured by the above-mentioned known technique is that when the menthol component is easily sublimed under normal temperature and normal pressure, a considerable amount is volatilized and lost when the menthol tobacco is stored and stored, and menthol added to the cigarette The component is not consistently bound to the original fragrance site but moves and transfers during storage.

The transition of menthol is moved to the filter or paper material even if the total amount of menthol added to the leaf tobacco side is moved to the leaf tobacco direction even if it is added to the filter or paper material, so in the process of manufacturing menthol tobacco It is not suitable to add menthol to either one site or only one site of a particular material. In particular, the transition of menthol is gradually absorbed to other sites by chemical bonding, the state of which is secondary to the filter or other adsorbents or additives along with physical adsorption. As the menthol transition proceeds not only by physical adsorption but also by binding or absorption by chemical reactions, the transition system of menthol components is reduced to mainstream smoke so that the menthol components added during cigarette combustion are not continuously transferred to a certain amount of smoke. Therefore, there is a problem that the smoker can not feel a uniform menthol odor when smoking.

In addition, after the cigarette is manufactured, a certain amount of time must pass for the menthol to reach equilibrium. Generally, 20 to 30 days must elapse to reach parallelism, which is then sold to consumers. Therefore, cigarettes containing menthol involve excessive time and cost in storage and distribution after manufacture, and during this period, the phenomena of menthol can not be uniformly carried out in all the qualities. As the excess menthol is sublimated and lost during the storage and storage periods, there is a problem that smokers cannot feel sufficient and uniform menthol odor when smoking with the increase in cost.

Accordingly, the present invention is to solve the above-mentioned problems, it is possible to reduce the storage period by shortening the time required until the menthol contained in the cigarette reaches the equilibrium, menthol is uniformly transferred to the mainstream smoke smoking To provide a cigarette and a method of manufacturing the same containing menthol to allow smokers to feel a constant and uniform menthol scent, as well as to increase the shelf life of menthol and to increase the quality of tobacco. have.

In order to achieve the above object, the present invention provides a cigarette manufacturing method for adding menthol in the process of manufacturing a cigarette by rolling the cigarette and the filter into a cigarette paper, 20 to 40 parts by weight based on 100 parts by weight of the total added menthol filter part In addition, 60 to 80 parts by weight is added to the leaf tobacco provides a method for producing tobacco containing menthol.

In another aspect, the present invention provides a cigarette containing menthol, characterized in that the manufacturing method.

Hereinafter, the tobacco containing menthol according to the present invention and a manufacturing method thereof will be described in detail.

According to the present invention, cigarettes and filters are rolled with cigarette paper to manufacture cigarettes so that menthol is effectively implemented in mainstream smoke during smoking so that the smoker can feel a uniform menthol odor and at the same time shorten the time for menthol to reach equilibrium. In the process, menthol is dispersed and added to the leaf tobacco and the filter, but it is characterized by limiting the addition amount to a range having a critical meaning. In the present invention, 20 to 40 parts by weight is added to the filter, and 60 to 80 parts by weight is added to the leaf tobacco based on 100 parts by weight of menthol added in the process of manufacturing a cigarette.

At this time, if the menthol added to the filter is less than 20 parts by weight, not only does it take a long time for the menthol to reach equilibrium, but also the amount of menthol that is transferred to the smoke at the beginning of the storage period is greatly reduced so that the smoker cannot feel a sufficient menthol odor. There is a problem. In addition, if the menthol added to the filter exceeds 40 parts by weight, the amount of menthol transferred to the mainstream smoke increases at the beginning of the storage period, but as the storage period becomes longer, the transfer rate is greatly reduced, so that There is a problem that the smoker can not feel a uniform menthol odor because the deviation is large. Therefore, the menthol added to the cigarette is preferably added 20 to 40 parts by weight to the filter and 80 to 60 parts by weight to the leaf tobacco with respect to 100 parts by weight of the total amount.

The method of adding menthol to the leaf tobacco and the filter can be applied to all known methods, for example, by dissolving menthol in a solvent such as alcohol, spraying or melting by heating, and other various known methods The method can be applied. In addition, the amount of menthol may be added within a known range, in the present invention was added 7% by weight of leaf tobacco.

As described above, when menthol is added to 20 to 40 parts by weight of the leaf tobacco and 60 to 80 parts by weight of the filter to produce tobacco, the menthol component is moved to the filter or leaf tobacco site after the cigarette is prepared to be in equilibrium. There is no need to take time, which greatly reduces the cost and time required for distribution, which contributes to cost reduction. In addition, the amount of menthol that is moved to the mainstream smoke is uniform so that smokers can feel a uniform menthol odor when smoking.

The filter used to manufacture tobacco may be applied as is known, for example, monoacetate filter; Double composite filters composed of acetate and carbon composites, acetate and paper composites, acetate and menthol containing materials (cotton, polyester, styrene, acrylic, etc.); Or after the acetate and the adsorbent (activated carbon, zeolite, silica gel) layer is connected, the triple composite filter having a three-layer structure such as acetate, carbon composite, paper, etc. in the winding portion may be applied.

At this time, according to the present invention, the filter plasticizer selected from triacetin, triethylene glycol diacetate or polyethylene glycol in the filter in order to absorb menthol to increase the retention rate and at the same time the menthol is easily desorbed to the mainstream smoke when smoking It adds 4-8 weight part with respect to 100 weight part.

When the amount of plasticizer added is less than 4 parts by weight with respect to 100 parts by weight of the filter, the amount of menthol absorbed by the filter decreases, so that the amount of menthol that is transferred to the mainstream smoke is lowered. Absorption and adsorption into the fiber occurs quickly, and there is a problem in that the rate of transition to mainstream smoke is lowered due to insufficient release effect during combustion.

More specifically, when the amount of plasticizer added to the filter is small, the amount of menthol is lowered because the amount of menthol absorbed into the filter is not enough and the amount of menthol is reduced to mainstream smoke. In addition, when the amount of plasticizer added to the filter is large, the amount of menthol transition is lowered because menthol is absorbed by the filter and crosslinking occurs frequently between the acetate cellulose fibers, thereby densely forming the structure between the cellulose, which causes menthol inside the filter. This is because the filtration efficiency is lower than the absorption rate, and a large amount of menthol is absorbed and adsorbed in the cellulose.

The leaf tobacco used to manufacture tobacco is generally applicable to various kinds of leaf tobacco used in the manufacture of tobacco. Preferably, the orient species and yellow species, which have good affinity with menthol, can enhance retention. It is good to use. If necessary, sugars, flavorings, alcohols, moisturizers and some solid substances may be further added in the manufacture of tobacco to improve tobacco taste.

According to the present invention, in order to further enhance the retention of menthol added to the leaf tobacco, a moisturizer selected from glycerin, propylene glycol, sorbitol, etc. having good binding properties with menthol components is added. The moisturizing agent is 3 to 100 parts by weight of the leaf tobacco. 4.5 parts by weight is added.

At this time, when the amount of the moisturizing agent is less than 3 parts by weight with respect to 100 parts by weight of leaf tobacco, the retention of menthol is lowered and the menthol is sublimed and lost depending on the storage period, so that smokers cannot feel sufficient menthol odor. When the added amount exceeds 4.5 parts by weight, the retention of menthol is increased, but there is a problem in that smokers cannot feel sufficient menthol odor as the menthol is easily detached and does not transition to mainstream smoke during the combustion of cigarettes. Therefore, it is good to add a moisturizing agent within the above range.

Tobacco according to the present invention prepared as described above can shorten the time required until the menthol in the cigarette reaches the equilibrium can not only induce time and cost savings in the storage and distribution after the manufacture of tobacco Instead, smokers can feel a sufficient and uniform menthol odor. In addition, by significantly increasing the retention of menthol, the shelf life of tobacco can be increased and the quality can be improved.

Hereinafter, the present invention will be described in more detail with reference to the following examples, which are only presented to aid the understanding of the present invention, but the present invention is not limited thereto.

<Example 1>

When 125mg of monoacetate filter per cigarette is absorbed by plasticizer triacetin to 8% by weight of the filter weight, and glycerol, moisturizer glycerine is added to 680mg of dried leaf tobacco to 4% by weight of tobacco. Absorbed by spraying. 5 mg of menthol was dissolved in ethyl alcohol and sprayed into the filter and leaf tobacco prepared above at the ratios shown in Table 1, respectively, and then manufactured as cigarettes. At this time, the leaf tobacco used was a mixture of yellow species 40%, Burley species 20%, orient 10%, platelet 10%, puffed kelp 15% and puffed beer 5%. The cigarette thus prepared was measured and the amount of transition of menthol and the amount of transition by the method specified below and the percentage is shown in Table 1 below.

-Analysis of menthol content of materials in the shell (transition amount)

The menthol content in the sample was determined by adding 10 g of kerosene applied by the AOAC (1990) method, 20 sheets of filter and wrapping paper, 8 sheets of tinfoil paper, and 4 pouches into 250 ml Erlenmeyer flasks, respectively. ) Was added to 150 ml of a solution prepared to 0.5 mg / ml in methanol, and then shaken for 2 hours, and the supernatant was quantified by gas chromatography. The GC used for the analysis was Hewlett Packard (5890.II), and the separation tube was a DB-bwax fused silica capillary column (60 m × 0.25 mm ID), and the nitrogen gas flow rate was 1 ml / min, inlet and detector (FID). The temperature was maintained at 250 ° C. and the separator tube temperature at 100 ° C. for 3 minutes, and then 1 μl of the sample solution was raised to 230 ° C. at 4 ° C./min using an HP 7673 series autoinjector. mode).

-Content in smoke (transition)

The menthol content transferred to the smoke was measured by smoking 20 cigarettes with a smoking machine (Heinr Borgwaldt Co.), collecting the whole smoke condensate with a Cambridge filter, placing them in a 250 ml Erlenmeyer flask, and using an internal standard. Anethole) was added to 100 ml of a methanol solution prepared to 0.5 mg / ml, and the mixture was left at room temperature for 24 hours, and the supernatant was quantified by gas chromatography. The GC separator used for the analysis was SPB-5 fused silica capillary column (30m × 0.53mm ID), the carrier gas nitrogen flow rate was 0.9 ml / min, inlet and detector (FID) temperature 250 ℃, separator tube temperature 120 2 μl of sample solution was injected into the injector in a splitless mode under isothermal conditions at ° C.

As shown in Table 1, when menthol was added only to the filter, the amount of menthol transferred to the smoke was about 2 times higher than when menthol was added only to the tobacco leaf, and when added only to the filter, 39% of the total amount of smoke was added after 2 days. The longer the storage period, the lower the efficiency. After 60 days, the efficiency decreases by 46% and 21% is converted to smoke. In addition, when only the filter is added, the amount of menthol is increased from 9.2% on day 2 and a large amount of menthol is increased after 60 days.

On the other hand, when menthol was added only to the tobacco leaf area, the transition to mainstream smoke was 12% on the second day, and the transition amount was very low (18 to 15% between 30 days and 60 days storage period). In addition, the amount of menthol transferred to the filter is 7.7% at the second day, 21.6% at 30 days, it can be seen that the menthol transition amount continuously increases with the storage period.

On the other hand, when menthol is manufactured by adding menthol within the scope of the present invention, that is, when the menthol is added to the filter part 20 to 40% by weight and the leaf tobacco is added to 40 to 80% by weight, the amount of menthol to mainstream smoke during smoking is constant. Not only can it be seen that it appears uniformly, it can be seen in Table 1 that the most efficient even when considering the transition equilibrium of menthol.

<Example 2>

In the 125 mg monoacetate filter per cigarette, triacetin, which is a plasticizer, is absorbed in the ratio shown in Table 2 with respect to the filter weight. Separately, 680 mg of dried leaf tobacco is 4% by weight of the tobacco weight. Absorbed by spraying the fragrance. 5 mg of menthol was dissolved in ethyl alcohol and sprayed into the leaf tobacco prepared above, which was then manufactured as a cigarette. At this time, the leaf tobacco used was a mixture of yellow species 40%, Burley species 20%, orient 10%, platelet 10%, puffed kelp 15% and puffed beer 5%. The filter used for manufacturing cigarettes was made by dividing monoacetic tow (3.3 / 35,000 denier) suction resistance 300mmH ₂ O (96mm, 500mg) into 4 parts and connecting the 24mm filter and the winding part to make a cigarette length 84mm and a cylinder 24.5mm cigarette. , Tip paper (porous paper), cigarette paper used 45C.U.

The cigarette thus prepared was measured in the same manner as in Example 1 the amount of transfer and the amount of transition and the results are shown in Table 2 below.

Triacetin added amount (% by weight) Mainstream smoke transfer amount according to storage time % Filter transition after 3 months 30 days 60 days 90 days 0 0.51 0.49 0.47 6.9 2 0.53 0.50 0.48 17.5 4 0.54 0.51 0.49 22.7 6 0.58 0.55 0.52 29.1 8 0.53 0.49 0.48 40.2 9 0.50 0.47 0.46 40.6 11 0.48 0.44 0.39 45.4

As shown in Table 2 above, as a result of measuring the amount of menthol transferred from leaf tobacco to mainstream smoke with respect to the amount of triacetin used as a plasticizer of the filter, triacetin was added to 100 parts by weight of When 4 parts by weight and 6 parts by weight of triacetin were added, more menthol was transferred to the mainstream smoke than when 3 parts by weight of triacetin was added. When 8 parts by weight of triacetin was added, 4 parts by weight of triacetin or Compared with the case where 6 parts by weight was added, it can be confirmed that the transfer amount of menthol is reduced.

<Example 3>

A 125 mg monoacetate filter per cigarette was used to absorb 9 mg of triacetin, a plasticizer, by spraying, and 680 mg of dried leaf tobacco was mixed with glycerol, propylene glycol and sorbitol at a ratio of 1.3: 1.3: 0.4, respectively. It was adjusted to the ratio shown in Table 3 with respect to parts by weight, and contained in the spraying method at the time of primary fragrance. 5 mg of menthol was dissolved in ethyl alcohol together with the fragrance used for secondary casing (top casing) in the leaf tobacco, and contained in a spray method, and then manufactured as a cigarette. At this time, the leaf tobacco used was a mixture of yellow species 40%, Burley species 20%, orient 10%, platelet 10%, puffed kelp 15% and puffed beer 5%.

The cigarette produced as described above was measured in the same manner as in Example 1 the amount of transition to the mainstream smoke and the results are shown in Table 3 below.

Moisturizer (% by weight) % Of mainstream smoke 2.5 21 3.0 22 3.5 24 4.0 23 4.5 22 5.0

As shown in Table 3, when the moisturizer concentration was added 3.0 to 4.5 parts by weight based on 100 parts by weight of the leaf tobacco, it can be confirmed that the amount of menthol component transferred to mainstream smoke is excellent.

As described above, the present invention shortens the time required for menthol to reach equilibrium by adding menthol to the filter and tobacco leaf in the thorn cigarette in the process of manufacturing tobacco, thereby reducing the time required for storage and distribution. It can induce time and cost savings, and the menthol is uniformly transferred to the mainstream smoke, so that smokers can feel a constant and uniform menthol scent during smoking. Especially, plasticizers and moisturizers added to the filter and tobacco leaf are utilized. It is a useful invention to provide a cigarette and a method for producing the same containing menthol to increase the shelf life of the manufactured tobacco by increasing the retention of menthol and to increase the quality of the tobacco.
