Description

Cigarette component carrying a fragrance and cigarette containing the same

The present invention relates to a cigarette constituent member that carries a fragrance and a cigarette containing the same.

When a volatile flavor component such as menthol is added to the tobacco yarn in a solution state, there is a problem in that the fragrance component is dispersed during a long period of time, and the fragrance effect is not sustained. To solve this problem, various reports have been made so far.

Examples of the arrangement of the perfume component in the tobacco portion of the burning portion or the roll paper coated therewith have been reported in Patent Documents 1 to 3.

Patent Document 1 discloses that a fragrance component is placed in a fragrance material placed inside a three-dimensional network structure of a glucan molecule, and is applied to a roll paper coated with a tobacco filler. In the cigarette of Patent Document 1, the flavor component is placed inside the three-dimensional network structure of the dextran molecule, and is fixed and held, so that the flavor retention property is good. However, since the flavor component is present in a small amount (20% by weight) in the dextran molecule, it is required for menthol (in the case of mint, menthol, etc., referred to herein as menthol). When a larger amount of the fragrance component is added, the amount of the fragrance material to be added to the cigarette is increased.

Patent Document 2 discloses mixing and dropping a liquid fragrance with a carrageenan sol The ionic solution (solution containing potassium ions) was added to prepare a granular gel, which was dried in the air to prepare a "stabilized aromatic substance to 180 ° C." However, in the method of Patent Document 2, since the granular gel is dried in the air, it takes a long time and a large-scale apparatus to prepare a large amount of material.

In the report of Patent Document 3, a slurry containing a fragrance component such as menthol and a polysaccharide is dried, and a flavor component is coated with a polysaccharide gel, and this is cut into a tobacco yarn. The flavor-containing sheet of Patent Document 3 has a high flavor content because the perfume component is coated with a polysaccharide gel and is not easily volatilized.

It is preferred to form a fragrance in a dispersed state in a solvent by the addition of an emulsifier, and for example, a hydrophobic fragrance or an oil-soluble fragrance can be used. These perfumes may be used singly or in combination.

Hereinafter, the present invention will be described by taking menthol as a fragrance as an example.

1. A composition containing menthol

In one embodiment, the cigarette-carrying component of the present invention can be grouped by using a combination of carrageenan, gellan gum, and gellan gum and tamarind gum in a cigarette component. A composition of a saccharide and menthol (hereinafter referred to as a composition containing menthol) is obtained. Preferably, the flavor-carrying cigarette constituent member of the present invention is obtained by applying the aforementioned fragrance composition to the surface of the cigarette constituent member.

The menthol-containing composition used in the present invention is in a state of having a fluidity at a heating temperature (for example, 60 to 90 ° C) as a state before drying.

The composition of the menthol-containing composition (slurry) may be, for example, 200 to 500 g of polysaccharide, 1000 to 2500 g of menthol, and 2 to 10% by weight of an emulsifier solution of 80 to 200 mL with respect to 10 L of water. The moisture content of the menthol-containing composition (slurry) is generally from 70 to 95% by weight, preferably from 80 to 90% by weight. The ratio (weight ratio) of the polysaccharide to menthol in the composition containing menthol may be 1:1 to 1:10.

The polysaccharide in the present invention has a property in which an aqueous solution is gelated upon cooling, and has a micelle of a fragrance such as menthol. As the polysaccharide having such a property, a polysaccharide selected from the group consisting of carrageenan, gellan gum, and a combination of gellan gum and tamarind gum can be used. Further, in the present invention, when carrageenan is used as the polysaccharide, a composition containing menthol may contain a smaller amount of gellan gum or other polysaccharides such as tamarind gum. Similarly, when gellan gum is used as the polysaccharide, it is also possible to contain a smaller amount of other polysaccharides such as carrageenan than the gellan gum in the composition containing menthol.

As the menthol in the present invention, 1-menthol can be used.

As the emulsifier in the present invention, a natural emulsifier such as lecithin can be used, and specifically, Sun Lecithin A-1 (Sun Chemical Co., Ltd.) can be used.

The slurry of the menthol-containing composition of the present invention may be prepared by (i) mixing an aqueous solution of a polysaccharide with water and heating to prepare an aqueous solution of the polysaccharide, and (ii) adding menthol and emulsification to the aqueous solution. It is prepared by a method of mixing and emulsification.

The step (i) can be specifically carried out by dissolving the polysaccharide while stirring it in a small amount. The heating temperature at this time is 60 to 90 ° C, preferably 75 to 85 ° C. In the step (ii), the slurry containing the menthol-containing composition has a viscosity of not more than 10,000 mpas (sol-like enthalpy) at the heating temperature, and does not interfere with the emulsification. Therefore, it can be carried out by using a homogenizer and a well-known emulsification technique.

2. Application of menthol-containing composition to cigarette constituent parts

In the present invention, the above menthol-containing composition is applied to a cigarette constituent member. It is preferably applied to the surface of a cigarette constituent member.

Specifically, the cigarette constituent member of the present invention is a constituent member disposed at a position that does not contact the mouth or the mouth of the smoker when the cigarette is assembled, in other words, the cigarette constituent member is disposed when the cigarette is assembled A component that is a position where the fragrance such as menthol is emitted simultaneously with the mainstream smoke by burning at the time of smoking.

More specifically, the cigarette constituent member is a tobacco filler or tobacco roll paper. More specifically, the tobacco filler is tobacco or flake tobacco.

When the menthol-containing composition is applied to a cigarette constituent member, the menthol-containing composition (slurry) is uniformly applied to the cigarette constituent member, and is not particularly limited, and the menthol-containing composition (slurry) can be used. The composition (slurry) containing menthol may be sprayed on the surface of the cigarette constituent member, or the cigarette constituent member may be immersed in a composition (slurry) containing menthol.

When a slurry of a composition containing menthol (about 60 to 90 ° C in a sol state) is applied to tobacco silk, the menthol-containing composition (slurry) can be directly added to the surface of the tobacco by a transfer pump, or by The way the nozzle smoke machine sprays on the surface of the tobacco wire. Alternatively, a menthol-containing composition (slurry) may be applied to the tobacco yarn, and the tobacco yarn may be immersed in a slurry of a menthol-containing composition.

When a slurry of a menthol-containing composition (about 60 to 90 ° C in a sol state) is applied to the sheet tobacco, the sheet tobacco surface may be extruded by a slit feeder and added, or a film coater or the like may be used. Coating and other methods. Alternatively, spray or dipping may be employed in the same manner as for the application of tobacco silk.

Applying a slurry of menthol-containing composition to tobacco paper (about 60 In the case of the sol state at 90 ° C, the film may be extruded or added by a slit feeder or coated by a film coater or the like as described above. Alternatively, spray or dipping may be employed in the same manner as for the application of tobacco silk.

For the tobacco silk, the application of the slurry containing the menthol composition The amount is 5 to 40 parts by weight, preferably 15 to 25 parts by weight, per 100 parts by weight of the tobacco yarn. In the case of flake tobacco, the slurry of the composition containing the menthol is used in an amount of 50 to 400 parts by weight, preferably 100 to 200 parts by weight, per 100 parts by weight of the tobacco. In the case of tobacco paper, the slurry of the menthol-containing composition is used in an amount of 10 to 70 parts by weight, preferably 30 to 50 parts by weight, per 100 parts by weight of the tobacco yarn.

a cigarette constituent member using a slurry containing a composition of menthol, The slurry of the menthol-containing composition is sufficiently gelled (40 ° C) before drying, and is generally temporarily cooled to a temperature (0 ° C) which does not cause the emulsion to freeze and is destroyed, that is, to 0 to 40 ° C. It is preferably 0 to 30 ° C, more preferably 15 to 25 ° C. The slurry of the menthol-containing composition before cooling here has a temperature of 60 to 90 ° C, preferably a temperature of 75 to 85 ° C, and is in a state of a sol. Such preliminary cooling, in a cigarette component using a slurry containing a composition of menthol, can be cooled only by a blower or a spot cooler (for example, Suiden SS-25DD-1) (for example, 10 ° C) ) for 2 to 3 minutes. Alternatively, the pre-cooling may also be carried out by using a cigarette component of a slurry containing a composition of menthol to contact a refrigerant generated by a cold and warm water generator (cooler such as Apiste Co., Ltd. PCU-1600R) ( For example, 10 ° C) is carried out through the tube for 1 to 2 minutes. Alternatively, preliminary cooling may be carried out by placing a cigarette constituent member using a slurry containing a composition of menthol at room temperature.

The aqueous solution of the polysaccharide used in the present invention is temporarily cooled and gelled. In addition, even if the temperature is raised, the temperature at which the gel is transferred to the gel is not easily solified, and the gel state can be maintained (see the examples described later). If pre-cooling is carried out before the slurry containing the menthol-containing composition is dried by this property, even if the thaumol-containing composition after the preliminary cooling is cooled, the temperature rises during drying, and it is not easy to contain it. The saccharide is solified, and the menthol coated with the polysaccharide is particularly difficult to volatilize. In the present invention as a result of pre-cooling, the menthol-containing composition can be exposed to heat in a subsequent drying step, whereby drying in a short time can be achieved.

The cigarette constituent member using the composition containing menthol is heated and dried, and can be dried by any heat drying such as hot air drying or infrared drying.

The drying of the cigarette constituent member using the composition containing menthol allows the sample temperature to be 100 ° C or lower in the total drying step, preferably at 70 to 100 ° C. In order to maintain the sample temperature below 100 ° C, a drying temperature of 100 to 130 ° C is preferably employed. In order to maintain the sample temperature at 70 to 100 ° C, a drying temperature of 100 to 130 ° C is preferably employed. Here, the "sample temperature" refers to the surface temperature of the menthol-containing composition in the drying step, and the "drying temperature" refers to the temperature in the dryer. When the hot air is dried, the temperature in the dryer is the same as the hot air temperature.

Preferably, the drying system comprises drying at a drying temperature of 100 ° C or higher (preferably 100 ° C to 130 ° C) for a period of 1/4 or more of the total drying time, and carrying the coating at a total drying time of 20 minutes or less. The cigarette constituent member of the fragrance is in a state of having a moisture content of less than 10%. Preferably, the drying is carried out at a drying temperature of 100 ° C or more, and the drying is carried out at the same temperature as the initial drying temperature or lower than the initial drying temperature (preferably 70 ° C or more and less than 100 ° C). dry.

The drying temperature is such that the temperature of the sample is usually 100 ° C or less in the total drying step, and the drying step may be a fixed temperature for the whole process or may be changed between the drying steps. When the drying temperature is changed, it is preferred that the drying is carried out at a high temperature drying temperature of 100 ° C or higher, and then dried at a low temperature of less than 100 ° C. In the present specification, "initial drying" means initial drying using a drying step at a high temperature of 100 ° C or higher. "Post-drying" refers to drying after the initial drying using a high temperature of less than 100 °C. Thus, when the combination of the initial drying at a high temperature and the late drying at a low temperature is performed, the temperature of the sample can be prevented from becoming too high, and the temperature of the sample in the entire drying step is usually 100 ° C or less, and the drying time can be shortened. advantage.

More preferably, it is dried by a drying temperature of 100 ° C or more and a total drying time of 1/4 or more, and then a drying temperature of less than 100 ° C and a total drying time of 1/4 or more. It is dried in the subsequent stage, so that the cigarette-constituting member carrying the fragrance can be made into a predetermined moisture content at a total drying time of 20 minutes or less (specifically, a cigarette-constituting member for carrying a fragrance containing a composition containing menthol in the tobacco yarn is applied. In the case of the flake tobacco or the tobacco paper, the composition of the cigarette containing the menthol-containing composition is a moisture content of about 10% by weight or less.

Thus, by combining the initial drying at a high temperature with the late drying at a low temperature, the cigarette-constituting member of the present invention can have a particularly high menthol content after production, and can maintain a special color after storage. High menthol content.

When drying by hot air drying, the initial drying may be, for example, 100 ° C The hot air temperature above 130 ° C is carried out for 4 to 6 minutes, and the late drying may be carried out for 4 to 6 minutes, for example, at a hot air temperature of 70 ° C or more and less than 100 ° C. The amount of hot air is, for example, 3 to 20 m/sec. The total drying time is 20 minutes or less, preferably 10 to 18 minutes.

The conditions of initial drying and post-drying (temperature, time, and air volume) can be appropriately set, for example, within the above range.

The drying temperature in the initial drying period may be fixed, or may be changed in a manner of decreasing from 100 ° C to 130 ° C. Further, the drying temperature in the post-drying chamber may be fixed, or may be changed in a manner of decreasing sequentially between 70 ° C and above and less than 100 ° C. For example, the dryer used in the embodiment described below has three drying chambers, and the sample is transported in the order of the first chamber → the second chamber → the third chamber, so that the first chamber and the second chamber can be the same or Different temperatures are used as initial drying (100 ° C or higher), and third chamber is used as post-drying (less than 100 ° C). The first chamber can be used as initial drying (100 ° C or higher), second chamber and third chamber. Used at the same or different temperatures as post-drying (less than 100 ° C).

The drying is preferably carried out until the moisture content of the constituent member of the cigarette carrying the fragrance becomes a predetermined moisture content (specifically, in the cigarette constituent member in which the composition containing the menthol is applied to the tobacco yarn, the weight is 12 weight. % or less; about 10% by weight or less of the cigarette-constituting member in which the composition containing the menthol is applied to the sheet tobacco or the tobacco paper. The moisture content herein refers to a value measured by the measuring method described in the examples below.

[10] Temperature-responsive sol transfer characteristics of polysaccharide-containing liquids

In this experiment, the temperature-responsive sol-gel transfer characteristics of the polysaccharide-containing liquid (slurry) of the following (1) to (3) were investigated.

[10-1] Modulation of polysaccharide-containing liquid (1) Carrageenan containing liquid

(2) gellan gum containing liquid

Shaoguan carrageenan-containing liquid and gellan gum-containing liquid are prepared as follows.

The water (0.1 L) was kept at 70 ° C, and the mixture was stirred with a high-performance stirrer-DMM manufactured by E-Tech Japan Co., Ltd., and the carrageenan was dissolved in a small amount to form a polysaccharide-containing liquid. (slurry).

(3) gellan gum and tamarind gum containing liquid

The gellan gum and tamarind gum containing liquid are prepared as follows.

While stirring 10 g (100 parts by weight) of water (heating at 80 ° C) with a stirrer (PRIMIX TKAUTOMIXER Model 40 / solution stirring rotor / 2000 rpm), the polysaccharide gellan gum and tamarind gum were mixed as described above. The ratio (weight ratio) was such that the total of the two polysaccharides became 500 g without causing agglomeration, and a small amount of dissolution was performed each time (the required time was about 20 minutes). Add directly at this temperature 2500 g (25 parts by weight) of 1-menthol. The stirrer was exchanged into a homogenizer (PRIMIX T.K.AUTOMIXER Model 40/mounting rotor-stator head/4000 rpm), and emulsified for 10 minutes, and further 200 mL (2 parts by weight) of an aqueous lecithin solution was added and stirred. The menthol is dispersed in a mixed polysaccharide aqueous solution of gellan gum and tamarind gum.

[10-2] Results

The polysaccharide-containing liquid (70 ° C) was cooled, and it took about 900 seconds to cool down to 25 ° C (0.05 ° C / sec). Then it took about 900 seconds to raise the temperature to 70 °C. The viscosity (fluidity) of the polysaccharide-containing liquid under such temperature change was measured by a rheometer (RheoStress 1 manufactured by Thermo-Haake Co., Ltd.).

The results of carrageenan-containing liquid are shown in Figures 7A and 7B; the results of gellan gum-containing liquid are shown in Figures 8A and 8B; the results of gellan gum and tamarind gel-containing solution are shown in Figure 9A. And shown in Figure 9B.

As shown in Fig. 7A, when the carrageenan-containing liquid is cooled to 25 ° C, the viscosity is lower near the sol-gel transfer temperature of about 50 ° C, but the viscosity rises rapidly at a temperature lower than the transfer temperature (coagulation) Gelatin). When the gel is heated, as shown in Fig. 7B, even if the heating exceeds the transfer temperature, it is not easy to return to the sol, and the gel state can be maintained.

As shown in Fig. 8A, when the gellan gum-containing liquid was cooled to 25 ° C, the viscosity was low until 50 ° C (the fluidity was high), but the viscosity was rapidly increased at 40 ° C or lower (gelation phenomenon). When the gel is heated, as shown in Fig. 8B, even if it exceeds the gelation temperature (40 ° C), it does not easily return to the sol, and the gel state can be maintained at a very high temperature.

As shown in Figure 9A, when the solution containing gellan gum and tamarind is cooled to 25 ° C, although the viscosity is still low to 40 ° C (high fluidity), at 35 ° C Underneath, the viscosity rises rapidly (gelation phenomenon). When the gel is heated, as shown in Fig. 9B, even if it exceeds the gelation temperature (35 ° C), it does not easily return to the sol, and the gel state can be maintained to a very high temperature.

As a result of the above, it was found that when the slurry containing the above polysaccharide was cooled and gelled, the temperature was not easily restored to the sol, and the gel state was maintained. According to the present invention, when the raw material slurry is subjected to preliminary cooling before the raw material slurry is dried, it is difficult to sol-form the polysaccharide contained in the slurry after the preliminary cooling is raised to the temperature at the time of drying. The covered menthol is not easily volatilized.

Since the picture in this case is experimental data, it is not a representative figure of this case. Therefore, there is no designated representative map in this case.
