BEST MODE FOR CARRYING OUT THE INVENTION

The present inventors have studied additives from various viewpoints for reducing aldehydes in mainstream tobacco smoke, and as a result, basic amino acid or basic amino acid salt is effective. I found this. The basic amino acid or basic amino acid salt includes, for example, arginine, arginine salt, lysine, lysine salt, histidine, histidine salt, o / retin, ordinium. A substance selected from the group consisting of tin salt, citrulline, citrulline salt, hydroxyzide and hydroxyzide salt is used. Of these, for example, arginine and its salts are recognized as food additives. In the tobacco of the present invention, the site to which the basic amino acid or the basic amino acid salt is added may be any of tobacco chopping, wrapping paper, and a filter, and is not particularly limited.

 The cigarette filter of the present invention may be a filter attached to the suction side of the tobacco portion of the cigarette, or a filter / letter in the form of a cigarette hood / leader.

 In the tobacco or tobacco filter of the present invention, the content of the basic amino acid or the basic amino acid salt is set to 1 mg or more by 1 mg or less. This is because it is difficult to obtain sufficient effects.

 In the present invention, the use of a basic amino acid or a basic amino acid salt in the presence of water increases the effect of reducing aldehydes.

 In the present invention, even when a basic amino acid or a basic amino acid salt is used together with a surfactant, the effect of reducing aldehydes is increased. This improves the wettability of the aqueous solution containing the surfactant and the basic amino acid or basic amino acid salt, so that the basic amino acid or basic amino acid salt can be reduced. Probably because of good dispersion. Non-ionic surfactants such as sorbic acid sodium sorbate, sodium oleate and sodium laurate are used as surfactants. Sucrose ester, sucrose myristate, sucrose palmitate, and sucrose stearate, but are not limited thereto. Not necessarily.

(Example) The method for measuring aldehydes in mainstream tobacco smoke employed in the following examples is based on the use of 2,4-dinitrophenylhydrazine (DNPH) as a trapping substance, and the production of high-speed derivatives. It is measured by liquid chromatography (HPLC). The target substances that can be measured simultaneously by this method are formaldehyde, acetoaldehyde, acetone, acrolein, propionaldehyde, crotonaldehyde, and methylethylethylketone. It is composed of eight components: ton and n-butyl aldehyde. In the following, an example is described for formaldehyde, among the aldehydes (carbonyl compounds) to be measured.

 First, dissolve 9.5 lg of 2,4-juthrofe-hydrhydrazine (DNPH) in 1 L of acetonitrile, add 5.6 mL of 60% perchloric acid, and add The collected liquid was prepared by making up to 2 L with pure water.

 The outline of the measuring device will be described with reference to FIG. As shown in FIG. 1, the DNPH collection liquid 12 is placed in the collection air-washing bottle 11. The volume of the air-washing bottle 11 was 25 OmL, the amount of the DNPH collection liquid 12 was 10 OmL, and the dead volume was 150 mL. Place the air-washing bottle 11 in an ice-water bath 13 and cool it with ice. The lower end of the glass tube 14 to which the cigarette 1 is attached is immersed in the collected liquid 12 in the washing bottle 11. Attach the glass tube 15 and the Cambridge pad 16 so that it communicates with the dead volume of the air-wash bottle 11, and attach the Cambridge pad 16 and the automatic smoker 17. Connect and.

Attach cigarette 1 to glass tube 14 Automatically smoke cigarette 1 under semi-smoking conditions. In other words, for each cigarette, one empty puff sucks 35 mL of smoke for 2 seconds and repeats the operation at 58-second intervals. While the mainstream smoke is bubbling, formaldehyde is derivatized by DNPH. Two cigarettes for measurement were used.

 The derivative formed as described above is measured by HPLC. First, the collected liquid is filtered, and then diluted with Trizma Base liquid (4 mL of collected liquid: 6 mL of Trizraa Base liquid). Measure this solution with HPLC. The HPLC measurement conditions are as follows. Column: HP LiChrospher 100RP-18 (5μ) 250 X 4mm

 Guard column: HP LiChrospher 100RP-18 (5μ) 4 X 4mra Column temperature: 30 ° C

 Detection wavelength: D A D 3 5 6 nm

 Injection volume: 20 μL

 Mobile phase: Gradient of three phases (Solution A: Ultrapure water solution containing 30% of acetonitrile, 10% of tetrahydrofuran and 1% of IPA, Liquid B: Ultrapure water solution containing 65% of acetonitrile, 1% of tetrahydrofuran and 1% of IPA, solution C: 100% of acetonitrile).

The structure of the cigarette used as the sample will be described with reference to the cross-sectional view of FIG. As shown in FIG. 2, this cigarette has a cigarette section 20 in which a tobacco cut 21 is wound with a wrapping paper 22 and a filter 31 with a cigarette wound in a molding paper 32. The filter part 30 and the filter part 40 are attached by chip paper 40. As a filter material, for example, cellulose acetate fiber Can be used.

 Note that a plurality of divided filters may be used, and the individual filters may be wound around the body by molding paper in a state where each of the filters is wound by individual winding paper.

 When testing cigarettes using a test filter to which a basic amino acid or a basic amino acid salt has been added, use a commercially available cigarette sorbet of 6 mg of tarnole. The tofu letter was cut, a single roll was taken out, and this was connected to a test filter to prepare a sample. A particle generator (Atomizer-1) was used to add the basic amino acid or basic amino acid salt to the test filter. When adding a basic amino acid or a basic amino acid salt in steps, disperse the cigarette in the commercial cigarette once, and use a nebulizer to cut the basic amino acid or basic amino acid. After adding the basic amino acid salt, the sample was re-wound with re-wound paper to produce a single-wound sample.

 The volume of formaldehyde was 110 μg as a result of measuring a single roll of a commercially available tanole 6 mg cigarette with the finale part cut off using the above measurement method with 7 puffs. .

 Example 1

As a base filter A, an acetate filter without a plasticizer was prepared. In addition, 35 mg of a 1% by weight arginine aqueous solution was added to the base filter A using a particle generator (Atomizer 1), and the mixture was harmoniously dried for 48 hours to obtain a test filter (arginine 3%). .5 mg) was prepared. Similarly, arginine.glutamate 10 wt% was added to base filter A. Add 35 mg of the aqueous solution using a particle generator (atomizer), and harmoniously dry for 48 hours to add another test filter (arginine and glutamate ₃ , 5 mg). ) Was prepared.

 Each filter was connected to the above-mentioned single winding part, and the amount of formaldehyde (FA) in the mainstream smoke was measured according to the above-mentioned measuring method. The results are shown in Table 1. From Table 1, it can be seen that cigarettes using arginine or arginine glutamate-filled / letter added to base filter A have sufficient formaldehyde for cigarettes I using base filter A. It can be seen that the metal has a reduced effect.

 Example 3

Add 35 mg of a 10 wt% aqueous solution of anoreginin, a 20 wt% aqueous solution of anoreginin or a 30 wt% aqueous solution of alginine to base finoletor B, and perform harmony drying for 48 hours. Therefore, three types of finoleletters (3.5 mg of anoreginin, 7.0 mg of anoreginin, or 10.5 mg of arginine, respectively) were prepared. Each filter was connected to the cigarette section described above, and the amount of formaldehyde (FA) in mainstream smoke was measured according to the measurement method described above. The results are shown in Table 3. Table 3 shows that the effect increases as the amount of arginine added to base filter B increases, but that 3.5 mg is sufficient.

 Table 3

 Example 4

 The following measurements were performed to evaluate the effect of reducing formaldehyde by arginine or arginine-glutamate in the presence of water.

As described in Example 1 and Example 2, base filter A or base filter letter B was added to a 1 wt% aqueous solution of arginine / reginine or 10 wt% of arginine'glutamate. A 35% aqueous solution was added, and immediately after the addition, the amount of formaldehyde (FA) in the mainstream smoke was measured in the same manner as above. In each case, the amount of arginine or arginine-glutamate was 3.5 mg. The results are shown in Table 4. Table 4 and Table 1 Comparison with Table 2 and Table 2 shows that the coexistence of arginine or arginine-glutamate with water increases the effect of reducing formaldehyde.

 Table 4

 Example 5

A 20 wt% aqueous solution of arginine was added to the tobacco cut in a mixing drum at a spraying rate of 20 wt% using a hand atomizer, and then dried at 80 ° C for 5 minutes in a dryer. . After that, the mixture was harmonized for 48 hours, and a single turn of 59 mm was prepared with 69.0 mg of tobacco cut. As the wrapping paper, 4P35 wrapping paper manufactured by Mishima Paper Co., Ltd. was used. The amount of alginine added is 4 wt% (27.6 mg) per chopping. The amount of formaldehyde in the mainstream smoke at the single outlet was measured in the same manner as above without a filter. The base cuts used for comparison were those obtained by adding 20 wt% spray of only water to the tobacco cuts. In the same manner as above, the base notch was used to form the mainstream smoke at the single winding outlet. The amount of aldehyde was measured. Table 5 shows the results. Table 5 shows that the addition of arginine in increments can significantly reduce formaldehyde in mainstream smoke.

 Table 5

 Example 6

 The same measurement as in Example 4 was performed to evaluate the effect of reducing formaldehyde by various basic amino acids or basic amino acids in the presence of water.

A predetermined amount of an aqueous solution of each of the basic amino acids or basic amino acids shown in Table 6 is added to the base filter B. Immediately after the addition, the amount of formaldehyde in the mainstream smoke is determined in the same manner as described above. FA) was measured. In each case, the amount of basic amino acid or basic amino acid added was 3.5 mg. Table 6 shows the results. Table 6 shows that not only arginine but also other basic amino acids or basic amino acids can reduce the formaldehyde. 2 Table 6

 Example 7

 The same measurement as in Example 2 was performed in order to evaluate the formaldehyde reducing effect of various basic amino acids or basic amino acids in the presence of a surfactant.

As shown in Table 7, a predetermined amount of an aqueous solution of arginine alone or an aqueous solution of arginine and various surfactants was added to the base filter 、, and after 48 hours of harmony, mainstream smoke was applied in the same manner as above. The amount of formaldehyde (FA) and the amount of increase in water (ΔW) were measured. The surfactant may be an ionic surfactant such as sodium sorbate, sodium oleate or sodium laurate, or a nonionic surfactant. Sucrose laurate ester, sucrose myristate ester, sucrose palmitate ester or sucrose stearate ester Was used. Table 7 shows the results. Table 7 shows that the combined use of a basic amino acid and a surfactant can achieve a formaldehyde reduction effect even in the absence of water. It is considered that the reason for this is that the use of an aqueous solution containing arginine and a surfactant improves the wettability of the aqueous solution to the filter and improves the dispersibility of arginine.
