Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a tobacco flavor improver comprising decaprenol (R=1) or isodecaprenol (R:lI) represented by the general formula %. It is a technology used in the tobacco industry.1 (Prior technology) Many compounds originally contained in leaf tobacco are known to be effective in improving the aroma and taste of tobacco. It is being Ionone compounds, which are carotenoid breakdown products,
Sesquiterpenoids are a representative group of compounds.

(Problems to be Solved by the Invention) In recent years, preferences for cigarettes have shown a tendency to diversify, and in particular, preferences are shifting toward products that are light in taste and rich in aroma. In line with this trend, many leaf tobaccos are being used as raw material for tobacco products, with a light taste and low nicotine and tar content. In addition, so-called artificial tobacco (hereinafter referred to as "artificial tobacco"), which is made from leaf tobacco that has undergone nicotine treatment, plants other than leaf tobacco, or various inorganic and organic components, has also come into use. However, such tobacco raw materials generally lack aroma and are irritating and often lack flavor, so it is necessary to add some kind of substance to improve the aroma and taste. The present inventors have conducted intensive research to solve the above-mentioned problems, and have developed a compound that improves the smoking taste of tobacco made from leaf tobacco, which has poor aroma and taste, and which is made from artificial tobacco. I did a search.

Decaprenol and isodecaprenol, which can be easily obtained by synthesis, were added to various tobacco raw materials that lack flavor and are irritating, and tests were conducted to evaluate the flavor of these products.Decaprenol and isodecaprenol It has been found that it has many excellent effects, such as harmonizing well with the original scent of tomoba, giving it a rounder flavor, emphasizing the tobacco-likeness, suppressing irritation, and having long-lasting effects.

There are no particular restrictions on the timing or means of adding this compound to tobacco raw materials, and it can be used by dissolving it in an organic solvent such as ethanol and adding it to shredded tobacco like other commonly used flavorings, or by adding it to shredded tobacco. The effect of improving flavor and aroma can also be achieved by incorporating it into materials for manufacturing cigarettes, such as wrapping paper, glue, filters, etc.

There are no particular restrictions on the types of tobacco to which this compound can be applied, and in addition to cigarettes, pipe tobacco, cigar tobacco, etc. made from regular leaf tobacco, natural fibers or plant tissue culture products may be used. Regarding the artificial cigarettes used,
The aroma and taste can be improved by adding the present compound during these manufacturing steps or after the products are manufactured. The amount of this compound to be added may be extremely small, preferably 0.00001 to 0.01% (by weight), preferably 0.0001 to 0.001% (addition of 0.0001% to 0.001% by weight) based on tobacco or tobacco manufacturing materials. Effects can be obtained.

(Example 1) 0.01 weight t of decaprenol for 509 shredded tobacco for Japan Tobacco brand name "Caster" just before rolling
% ethanol solution was sprayed and added so that the amount of decaprenol to the shredded tobacco was o, oooos wt%, and then rolled up with paper, and the rolled product of the above shredded tobacco without decaprenol was used as a control product, and when these were smoked. Odor and taste were compared using the two-point discrimination method. The evaluations of 20 specially trained expert panels are as shown in Table 1.

For father-in-law, there is a significant difference in the risk rate of 5chi. show something.

From the above table, it can be seen that decaprenol has the effect of significantly improving the odor and taste of tobacco products.

(Example 2) Waste tobacco is extracted with hot water at 100°C, separated into a water-soluble part and a water-insoluble part, and the water-insoluble part is beaten. The mixture with kraft pulp is molded into thin paper.

Decaprenol was added to 60 g of sheet-shaped recycled tobacco made by restoring the above-mentioned water-soluble portion to this thin paper in the same manner as in Example 1, so that the amount of the added amount was o, ooos weight φ, and then treated. The above-mentioned shredded and rolled-up sheet-shaped recycled tobacco without the addition of decaprenol was used as a control, and the odor, taste, and irritation at 9 o'clock were compared using the two-point discrimination method. Specially trained expert panel 2
The evaluation of 0 people was as shown in Table 2.

The results show that the odor and taste are significantly improved with the addition of decaprenol, and the irritation suppressing effect is also significant.

(Example 3) 0.0 of isodecaprenol was added to 50 g of Nippon Tobacco brand name 1 Seven Star tobacco just before rolling.
Add a 1% i% ethanol solution by spraying so that the amount of indecadanol to the shredded tobacco is o, oos wt%, roll it into paper, and roll the shredded tobacco without isodecaprenol. As a control product, the smell and taste when smoked were compared using the two-point discrimination method.

In particular, the evaluations of 20 trained expert panels are shown in Table 3.

Table 3 The numbers in the table indicate the number of people who rated it as good. shows.

Arrows indicate significant differences at a 5% risk rate. show something.

From the above table, it can be seen that isodecaprenol has the effect of significantly improving the odor and taste of tobacco products.

(Example 4) A sheet produced in Example 2 using a mixture of C, M, C, (carboxymethylcellulose) glue, which is a glue for cigarette shredded paper, and the present compound at a concentration of 0.003% by weight. The smoking taste of these products was compared using a two-point discrimination method using a control product made of shredded rolled-up products made from recycled tobacco, and a control product made using a sizing solution without the addition of isodecaprenol. In particular, the evaluation by a panel of 20 well-trained experts was as shown in Table 4.0 The numbers in Table 4 indicate the number of people who rated it as good.

Arrows indicate significant differences at a 5% risk rate. show something.

As a result, it was found that isodecaprenol improves the aroma and taste of cigarettes even when added to glue for rolling adhesive, which is a material for cigarette manufacturing, and furthermore, it was found that the irritating odor caused by C0M and C0 was significantly suppressed. did.

(Effects of the Invention) As is clear from the above examples, decaprenol and isodecaprenol are very useful as tobacco flavor improvers.
