Description

Smoke, bad breath, bad spice composition

The present invention relates to a smoke-odor bad breath improving perfume composition.

In the past, in order to remove smoke odor, a technique for carrying a specific deodorizing component in a tobacco filter or a roll paper is known (refer to Japanese Laid-Open Patent Publication No. Hei 7-250665 and JP-A-2009-179708). However, these techniques are aimed at eliminating the odor generated directly by tobacco, and not the bad breath of the smoke odor. In fact, the use of the deodorizing ingredients disclosed in the above documents directly does not achieve the elimination of smoke and bad breath. To improve the bad breath of smoke, it is necessary to consider the desorption of the perfume ingredients in the mouth.

On the other hand, in recent years, the awareness of bad breath has been improved, and techniques for improving the flavor and the deodorant for bad breath are being developed (JP-A-2005-289918, JP-A-2005-170906, and JP-A-2003- Japanese Patent Publication No. 175095 and Japanese Patent Laid-Open Publication No. 2009-190990. In addition, a technique for masking a fragrance for bad breath containing smoke and odor is also disclosed (refer to Japanese Laid-Open Patent Publication No. 2004-18431). However, if such a bad breath improving fragrance or deodorant is added directly to tobacco, it is necessary to add a large amount of a strong aromatic ingredient, which may damage the original flavor of the tobacco. That is to say, in order to improve the flavor of the smoke and bad breath added to the tobacco, it is desired to obtain a small amount of the effect of improving the bad breath of the smoke. In addition, although a method of including a bad breath improving material or a deodorant in the mouth after smoking is considered, this case must be performed separately after smoking, which is not preferable. Thus, in the prior art, the tobacco aroma is ensured while the smoke and bad breath accompanying the smoking is in the smoking one. The improvement in the action is not fully achieved.

SUMMARY OF THE INVENTION An object of the present invention is to provide a smoke-odor bad breath improving perfume composition which can improve smoke and smoke bad breath with a small amount of addition and which does not impair the original aroma of the tobacco, and a smoking article containing the same.

Flavoring ingredients of aromatic ketones, terpene hydrocarbons, terpene ethers, and aliphatic esters.

According to still another aspect of the present invention, a smoking article which supports the above-described smoke-odor bad breath improving fragrance composition is provided. The odorous odor-reducing flavoring composition of the present invention can be added to tobacco in any step of adding the flavoring to the general tobacco. Further, the smoke-odor and bad breath improving flavor composition of the present invention may be added to the final smoking article (cigarette or the like) at any concentration, but it is preferably 0.5 mg or more and 15 mg or less for 1 g of the tobacco material, more preferably 1 g of the tobacco material is added in a ratio of 0.5 mg or more to 5 mg or less. As the tobacco material, any tobacco material such as tobacco leaves (yellow, burley, orient), flake tobacco, or the like can be used, and these tobacco materials are usually used in a shredded form for smoking articles. The cut tobacco can be in an expanded state. Further, the smoke-odor bad breath improving flavor composition of the present invention can be added to any position of a tobacco material, a material product (tobacco filter, etc.).

The present inventors thought that in order to improve the smoke and bad breath, it is necessary to discharge the fragrance composition at the time of exhalation. In other words, the fragrance is present in the mouth before it reaches the mouth, and when it reaches the mouth, it does not spit out when exhaling and remains in the mouth. When the fragrance is not exhaled when exhaled, it is considered to be unsuitable as a smoke-odor bad breath improving fragrance composition even if it has a high shielding effect.

The inventors performed chemical analysis on most of the known perfume ingredients, and measured the release rate L of the perfume ingredients in exhalation after smoking for 3 minutes.

The release rate L (%) in exhalation was calculated by dividing the concentration of the fragrance component Cex (area/mL) in the exhalation by the concentration of the fragrance component Cms (area/mL) in the main smoke stream and multiplying by 100. The area is the peak integrated area analyzed by GC/MS.

When the value of the release rate L in the exhalation is 0.1% or more, it is found that the amount of the fragrance excretion in the sufficient exhalation which improves the smoke and bad breath is ensured within the range of the amount of the fragrance to be allowed in the design of the tobacco.

Further, it is known that the fragrance component having a release rate of 0.1% or more in the above-mentioned exhalation can be classified into two groups having a certain range of the vapor pressure Vp and the water/octanol partition coefficient P. In other words, 2% Vp<210 and 1.5≦logP≦6.5 of the fragrance component A, and 210≦Vp≦10000 and -1≦logP≦3 of the fragrance component B.

Further, by the sensory evaluation, the components having a great improvement in bad breath are selected from the fragrance component A and the fragrance component B (the functional evaluation method will be described later).

Here, the present inventors predicted that the physical properties of the fragrance component A and the fragrance component B are different, so that the behavior in the mouth is also different, and different effects are provided for the improvement of the smoke and the bad breath. Specifically, since the vapor pressure of the flavor component B is high, it is predicted that the bad breath bad breath is given to the bad breath after smoking (hereinafter referred to as "starting effect"). In addition, since the vapor pressure of the flavor component A is low, it is predicted that the bad breath improving effect (hereinafter referred to as "sustaining effect") is imparted to the smoke and the bad breath for a long period of time. Table 1 shows the characteristics of the fragrance component A and the fragrance component B. In addition, it does not contain the components in the fragrance component A and the fragrance component B, in other words, the vapor pressure is relatively high and relatively hydrophobic, and it is mostly volatilized during smoking. However, the vapor pressure is low and the relatively hydrophilic component reaches the mouth, but it dissolves in the mouth and does not spit out during exhalation. Therefore, it is considered that the bad breath improving effect cannot be obtained.

Then, a fragrance (comparative example) having only a combination of the fragrance component A or only the fragrance component B, and a fragrance of the combination of the fragrance component A and the fragrance component B (Example) were prepared as described later, and the smoke and bad breath were improved. Do a functional evaluation. As a result, it was found that the combination of the fragrance component A and the fragrance component B can exhibit a sufficient smoke-odor bad breath improving effect in a small amount as compared with the case of only the fragrance component A or the fragrance component B alone.

Therefore, the method for selecting a smoke-odor and bad breath improving perfume composition of the present invention has the steps of: analyzing the amount in the mainstream smoke and the amount of release in the breath, and the concentration of the flavor component in the exhalation Cex (area/) mL) The step of selecting the fragrance component in which the release amount in the exhalation is 0.1% or more, divided by the concentration of the fragrance component in the mainstream smoke Cms (area/mL) and multiplied by 100 Step. More preferably, the method further comprises the step of selecting a fragrance component having a smoke-odor and bad breath improving effect from the result of the functional evaluation of the odor intensity of the smoke and the bad breath.

Further, it can be seen that when the weight of the fragrance component A is larger than the weight of the fragrance component B (A>B), compared with the case of less than or equal to (A≦B), there is an effect of improving the smoke and bad breath.

Thereby, the smoke and bad breath can be improved without damaging the original flavor of the tobacco.

The embodiments of the present invention are described in more detail below.

(1) Method of calculating the release rate in exhalation

(1.1) The release rate of the fragrance component in exhalation after three minutes of smoking is L (%) is the concentration of the fragrance component in exhalation Cex (area / mL) divided by the concentration of the fragrance component in mainstream smoke Cms (area / mL ) Multiply by the value of 100.

(1.2) Sampling method

(1.2.1) Preparing cigarettes

The cigarettes used in the analysis were all commercially available cigarettes "SEVEN STARS Lights BOX". The perfume diluted with ethanol was added to the cut tobacco before the analysis of the fragrance and used for the test. Specifically, 10 μL of a mixture of 20 to 30 perfume ingredients each at a concentration of 100 μg/10 μL was added to the cut tobacco.

(1.2.2) Capture exhalation

The experimenter rinsed the mouth with water before smoking. Then smoke the cigarette. The smoking interval is 30 seconds, and the smoking and breathing times are 7 times. After smoking, the trap tube (connected to 2 TENAX-TA) was placed in the mouth, and the headspeace (exhaled breath) in the mouth was captured by a pump at 100 mL/min. Capture exhalation The time is 1 minute after 3 minutes as the starting point at the end of smoking. After the collection, nitrogen was circulated at 100 mL/min for 4 minutes in order to volatilize the water which would cause an obstacle to the analysis.

(1.2.3) Capture mainstream smoke

Mainstream smoke is captured using a mass flow controller and a smoker made up of pumps. The smoking interval was 30 seconds and the smoking flow rate was 55 mL/2 sec. It is not captured until the third inhalation from ignition to the next. The fourth mainstream smoke was ventilated to the trap (TENAX-TA).

Tables 3 and 4 show the following.

In the case of only the fragrance component A or the fragrance component B only (Comparative Examples 1 and 2), the "initial effect" and the "sustained effect" have insufficient effects on the improvement of the smoke and bad breath, so that the overall smoke and bad breath is improved. insufficient. On the other hand, in the case where the fragrance component A and the fragrance component B are combined (Examples 1 to 16), It can be seen that the "starting effect" and "sustained effect" are both high in bad breath improving effect, and the overall smoke and bad breath improving effect is also sufficient.

Further, when the weight of the fragrance component A is more than the weight of the fragrance component B (A>B) (Examples 1, 3 to 16), it is more preferable than the case of A<B (Example 2). The smoke smells bad breath and improves the effect. The weight of the fragrance component A and the fragrance component B is preferably from 5.5:4.5 to 9.9:0.1.

Further, in the case of combining the fragrance component A and the fragrance component B (Examples 1 to 16), the amount of the fragrance composition added per gram of the tobacco material is 0.5 mg or more and 15 mg or less, and the smoke odor and bad breath improving effect can be obtained. When the amount of the material-scented composition in the tobacco is 0.5 mg or more and 5 mg or less, the smoke-odor and bad breath improving effect can be obtained. Thus, a sufficient smoke and bad breath improving effect can be obtained per 1 g of the tobacco material even if a very small amount of 0.5 mg is added.
