Description

[Detailed Description of the Invention] An attempt has already been made to remove harmful components such as nicotine and tar from smoke by using a filter in cigarettes, as disclosed in US Patent No. 13471.
3, 253296, 3079926, and Japanese Patent Publication No. 50-76300.

These filters are characterized by the use of tannic acid, tannic acid metal salts, coffee, tea leaves, or lung tissue from animals such as cows, birds, and pigs as filter media components. Also, currently available on the market are hydrated or non-hydrated fibers, activated carbon, and the like.

Perhaps because the products described in the above-mentioned patents emphasize the removal of harmful ingredients, there is less interest in flavor, which is the original purpose of a good product. In other words, tannins, tannin-containing substances (coffee, tea leaves), or tannin metal salts are only expressed as tannic acid, and there is no interest in the type of tannins. Only in Japanese Published Patent No. 50-76300, the purity is limited to ``Japanese Pharmacopoeia'' or purified tannic acid for glutinous making, and when tannic acid is used, it is decomposed by the heat of smoke during smoking. Since it produces an unpleasant taste, tannic acid metal salts are used to prevent this.

Tannin or tannic acid is a general term for compounds that have the property of tanning animal rawhide, and their chemical structures are not uniform. Therefore, it is a matter of course that tannins or tannic acids used as materials for tobacco filters are preferable or undesirable, and some are more or less effective, depending on their chemical structure.

Let's further explain the chemical structure of tannins.

Japanese Pharmacopoeia (for sake brewing, same for refined tannins) ■Turkey raw material for double roe ■Raw material for double shi (galling) ■Tea leaves mixed with the following tannins in raw material for double shi (Noka.V)
ol. 28. p264) Detected gallic acid, m-digallic acid catechin, gallocatechin, and their gallic acid ester catechin: Thiest nuts (according to the present invention) In addition, tannins include flavones with properties similar to tannins, It is said to contain many substances such as quercetin.

■Tobacco filters using double or gallic tannins have a strong tendency to make the taste of tobacco too bland, and are not necessarily suitable for all smokers as a preferred tobacco flavor.

The present invention has particularly conducted extensive research on this point and has discovered thiest-nut tannin as the most suitable tannin for tobacco. By adding coffee extract, tea leaf extract, and licorice extract glycyrrhizin to this, we succeeded in imparting distinctive and desirable flavors to tobacco.

Furthermore, by using Edo Plus (manufactured by Takeda Pharmaceutical Co., Ltd.) in the body of tannins, we succeeded in further increasing the effect.

This aid plus is as follows.

It is a porous fibrous natural product with a tunnel structure whose main component is magnesium silicate, and has thickening, adsorption, and caking properties. Specific surface area: 260-330m2/g, water absorption: 11
It has an apparent hardness of 0 to 130%, an apparent hardness of approximately 2, and a fire resistance of 1400°C or higher.

The Thiest Nut tannin used is treated with an ion exchange resin, adjusted to a concentration of 6 to 8%, heated to 60 to 70°C, and a small amount of coffee, tea leaf extract, and glycyrrhizin are dissolved in this as necessary. Make a liquid.

Add 1 part of AED+ granules to 2 parts of the above liquid and mix. When left as it is for about 20 hours, most of the liquid is absorbed into the AED+ and becomes a solid lump. Add water and rose Λ
Take out, wash lightly with water, dehydrate, air dry, and dry below 60°C to obtain granules for tobacco filters.

A small amount of this is stuffed between the tobacco leaf and the mouthpiece of the cigarette. This cigarette is a favorite product with excellent features.

Next, a more detailed explanation will be given with reference to Examples.

Thiestonut tannin Castanea cesva or C. denta
Tannin powder produced by water extraction from ta is 50 to 6
Dissolve in 0℃ warm water to make approximately 8-10% liquid. This liquid is treated with a cationic ion exchange resin (for example, Amberlite 1R120B) and then an anionic ion exchange resin (for example, Amberlite 1RA410) at room temperature.

Treatment tower: diameter 60cm, height 1200cm, passing speed (S
V): 3.5-4.0 Adjust this solution to a concentration of 6%.

Add 40 to 80 meals of Aid Plus for the body.

Example 1. Add 200 parts of the above 6% cheesetonut tannin solution to 65 to 7
The mixture was heated to 0° C., and 100 parts of the above AED+ was added thereto, mixed, and left for about 20 hours. The liquid is sucked into the AED+ and becomes a lump. Use water to loosen any lumps, rinse, and dehydrate. The total amount of separated liquid was about 3000 parts. (After air-drying in the evening, further drying at below 60°C. Yield: 110 parts Example 2 Dissolve 2 parts of instant coffee powder (trade name: Nescafue) in 200 parts of the tannin solution of Example 1. Add 100 parts of Edo Plus. Example 3 10 parts of Sencha leaves (trade name: Tokujo Aoyagi) were added to 200 parts of the tannin solution from Example 1, and extracted for 5 minutes at 80 to 65°C. After that, filter through a cloth. Add 100 parts of AED+ to this and Example 1.
Process in the same way as . 110 parts after drying Example 4 0.2 part of 92% glycyrrhizin monopotassium and 0.2 part of citric acid were dissolved in 200 parts of the tannin solution of Example 1. 100 parts of AED+ was added to this and the same treatment as in Example 1 was carried out. 110 dry copies Example 5 0.05 g of the dried product of Examples 1 to 4 above was placed between the tobacco leaves and the mouthpiece filler of a cigarette, and the tip of the cigarette was lit and smoked to examine the change in flavor.

Classification Compared to the original Example 1 Alternative to a desirable elegant flavor.

　　　2　It has a pleasant cigar-like flavor.

　　　3　It has a refreshing flavor.

　　4　It has a sweet and elegant taste.

The taste is improved as described above, and the unpleasant aftertaste and bland taste that occur when using five-fold tannins are not produced.
