Description

TECHNICAL FIELD [0001] The present invention relates to a perfume composition for improving tobacco odor,

The present invention relates to a perfume composition for improving tobacco odor control.

2. Description of the Related Art [0002] Conventionally, there has been known a technique of holding a specific deodorant component on a cigarette filter or a roll to deodorize a cigarette odor (Japanese Patent Application Laid-Open No. 7-250665 and Japanese Patent Laid- No. 2009-179708). However, all of these technologies are intended to deodorize odors directly originating from tobacco, and not to improve tobacco odor. In fact, the deodorization of the tobacco odor is not achieved by simply using the deodorizing component disclosed in the above document. In order to improve the tobacco odor of a cigarette, it is necessary to consider desorption of fragrance components in the oral cavity.

On the other hand, with recent increases in awareness of bad breath, techniques for improving bad breath improving perfume and deodorant have been developed (Japanese Patent Application Laid-Open No. 2005-289918, Japanese Patent Laid-Open No. 2005-170906 , Japanese Patent Application Laid-Open No. 2003-175095, and Japanese Patent Laid-Open Publication No. 2009-190990). Further, a technique relating to a fragrance for masking bad breath containing tobacco smoke is also disclosed (see Japanese Patent Application Laid-Open No. 2004-18431). However, when these bad breath improving fragrances and deodorants are directly added to cigarettes, it is necessary to add a large amount of components that emit strong aroma (fragrance), and the flavor of the original tobacco is deteriorated. That is, in the tobacco odor improving fragrance to be added to tobacco, it is required to exhibit an effect of improving the tobacco odor by an extremely small amount. It is also conceivable that the odor-improving fragrance or deodorant is put into the mouth after smoking (smoking), but in this case, operation after the smoking is required, which is not preferable. As described above, in the prior art, it is not sufficiently achieved to improve the tobacco odor caused by smoking in one operation, which is called smoking, while securing the tobacco flavor.

DISCLOSURE OF INVENTION

According to another aspect of the present invention, there is provided a smoking article carrying the above-described tobacco-related breath improving perfume composition. The tobacco smoke breath improving perfume composition of the present invention can be added to a cigarette in any step of adding a perfume to a cigarette. Further, the tobacco smoke breath improving perfume composition of the present invention may be added to the final smoking article (such as a cigarette) at a certain concentration, but is preferably 0.5 mg to 15 mg, Is added in a proportion of 0.5 mg to 5 mg based on 1 g of the tobacco. As tobacco materials, any tobacco materials such as leaf tobacco (yellow species, burley, Orient species, etc.) and sheet tobacco can be used, and these tobacco materials are usually used for smoking articles in the form of flesh. The flesh may be in the expanded form. In addition, the tobacco smoke improving perfume composition of the present invention may be added at any position of a tobacco material, a material (a cigarette filter, etc.).

Carrying out the invention  Best form for

The inventors of the present invention have thought that it is necessary for the perfume composition to be discharged to the exhalation region in order to improve the tobacco odor. That is, depending on the fragrance, there is a thing to volatilize before reaching the oral cavity, or to remain in the mouth without being discharged to the exhalation after reaching the oral cavity. If the perfume is not discharged to the exhalation, even if it has a high masking effect, it is considered that it is not suitable as a perfume composition for improving tobacco odor.

The present inventors carried out a chemical analysis on a large number of existing fragrance components and measured the release rate L of the fragrance component into the breath group three minutes after smoking.

The release rate L (%) during exhalation is calculated by dividing the perfume ingredient concentration C _ex (area / mL) in the exhalation by the perfume ingredient concentration C _ms (area / mL) in the mainstream smoke and multiplying by 100. area is the peak integration area by GC / MS analysis.

It has been found that when the release rate L is 0.1% or more in this rhythm, the perfume discharge amount in the breath is sufficient to improve the tobacco odor within the range of the amount of the perfume added in the design of the cigarette.

It was also found that the fragrance component having a release rate L of 0.1% or more in the above exhalation can be classified into two groups in which the vapor pressure Vp and the water / octanol partition coefficient P are in a constant range. That is, the perfume component A having 2? Vp <210 and 1.5? Log P? 6.5 and the perfume component B having 210? Vp? 10000 and?

Further, a component having a particularly bad odor improving effect was selected from the flavor component A and the flavor component B by the sensory evaluation (the sensory evaluation method will be described later).

Here, the inventors of the present invention predicted that the fragrance component A and the fragrance component B differ in physical properties from each other in terms of their behavior in the mouth and make a different contribution to the improvement of the tobacco odor. Specifically, since the vapor pressure of the perfume component B is relatively high, it is expected that it contributes to the bad breath improvement effect (hereinafter referred to as "synergistic effect") immediately after smoking of the cigarette bad breath. In addition, since the vapor pressure of the perfume component A is comparatively low, it is expected that the perfume component A contributes to the long-term effect of improving the bad breath of tobacco stomachs (hereinafter referred to as "sustained effect"). Table 1 shows the properties of the perfume component A and the perfume component B. In addition, the components which are not contained in the perfume component A and the perfume component B, that is, the components of which the vapor pressure is relatively high and relatively hydrophobic, are volatilized in the course of smoking and most of them can not reach the mouth and the vapor pressure is relatively low, It does not contribute to the bad breath improvement effect because it is not discharged during the breath while being dissolved in the moisture of the mouth.

Thus, as described later, a combined flavor (only comparative example) containing only the flavor component A or only the flavor ingredient B and a combined flavor (example) with the flavor ingredient A and the flavor ingredient B were prepared, I appreciated. As a result, it was found that the combination of the perfume component A and the perfume component B in combination with the perfume component A alone or the perfume component B alone can exert a sufficient amount of tobacco odor improvement effect in a small amount.

Therefore, the method for selecting the tobacco smoke improving perfume composition according to the present invention comprises the steps of analyzing the release amount in the mainstream smoke and the release amount in the exhalation, and the step of analyzing the perfume ingredient concentration C _ex (area / mL) C _ms (area / mL) and multiplying by 100 to select a fragrance ingredient having a release rate L of 0.1% or more. More preferably, there is also a step of selecting a flavor component having an effect of improving the tobacco odor by the sensory evaluation result of the odor intensity of the tobacco odor among the selected flavor components.

In addition, it was found that the effect of improving the tobacco odor especially in the case of small or the same (A &amp;le; B) is particularly large when the weight of the perfume component A is larger than the weight of the perfume component B (A &amp;bull; B).

This makes it possible to improve the tobacco smoke without harming the flavor of the original tobacco.

From Table 3 and Table 4, the following were found.

In the case of only the perfume component A or only the perfume component B (Comparative Examples 1 and 2), since the effect of improving the tobacco odor of either of the "synergistic effect" and the "sustained effect" was insufficient, It was insufficient. On the other hand, when the fragrance component A and the fragrance component B were combined (Example 1-16), the effect of improving the bad breath at the same time as the "synergistic effect" and the "sustained effect" did.

When the weight of the perfume component A is larger than the weight of the perfume component B (A> B) (Examples 1 and 3-16), compared with the case of A <B (Example 2) An improvement effect can be obtained. The weight ratio of the perfume component A to the perfume component B is preferably 5.5: 4.5 to 9.9: 0.1.

When the perfume composition A and the perfume ingredient B were combined (Example 1-16), the amount of the perfume composition added was 0.5 mg to 15 mg per 1 g of the tobacco material, and 0.5 mg to 5 mg per 1 g of the tobacco material, An improvement effect can be obtained. As described above, even when the addition amount of 0.5 mg per 1 g of the tobacco material is very small, it is possible to obtain a sufficient tobacco odor improvement effect. The addition amount of 0.5 mg per 1 g of the tobacco material is also preferable from the viewpoint of tobacco flavor.
