Description

A FILTERING MATERIAL FOR CIGARETTE AND ITS

PROCESS TO USE GINKGO LEAF INGREDIENTS

FIELD OF THE INVENTION

The present invention relates to a granular filtering material comprising a ginkgo leaf in main, and more particularly, a granular cigarette filtering material using adsorption ability of kolophonium, extracted from a large amount of oleoresin called ginkgo contained in a ginkgo leaf, to remove a toxic component of the cigarette efficiently, and using a bomylacetate C₁ H₂₀O₂, 196 to have a peculiar flavor additionally.

DESCRIPTION OF THE RELATED ART

A cigar is a natural plant containing mainly Nicotiana Tabacum, called in nomenclature, and one of the favorite foods including various ldnds, such as a cigar, a cigarette, a pipe, a snuff, and a chewing tobacco. Among them, the cigarette is sold in main in the worldwide market, and is toxic strongly.

Generally, a cigarette smoke before a smoker's inhalation, when the cigarette is inflamed, is called as a main smoke, and a cigarette smoke after a smoker's exhalation is called as a subsidiary smoke. When smoking a cigarette, a smoker can satisfy his/her desire by nicotine contained in the cigarette. The cigarette smoke includes particles generated by dry distillation of a gas, a steam, and a tar, which are generated during incomplete combustion of the cigarette. Therefore, most components of the cigarette smoke are liquids, and the size of the components, the particles, is from 10^~5 to 10^-10 cm, which is relatively minute comparing with a particle of the cloud and the fog.

Nicotine is one of the typical components contained in the cigarette smoke comprising such minute particles. In addition to nicotine, not only a nitrogen compound, an organic acid, and an inorganic matter are included, but also more than two hundreds of compounds including tar are included in the cigarette smoke. The cigarette smoke contains minute particles generated by the dry distillation happened in the case of inflaming the cigarette at the temperature of about 700 to 880 °C, and an electro microscope shows more than a million particles, in a size of 0.01 μm to 1.0 μm, per a smoke cigarette of 1 ml.

On the contrary, while the concentration of a carbon monoxide CO causing an oxygen deficiency state is 50 ppm in the air, the concentration of carbon monoxide CO in the cigarette smoke is about 45,000 to 50,000 ppm in maximum. For carbon dioxide CO , the concentration in the cigarette smoke is 250 ppm, while the concentration in the air is 0.02 ppm.

Therefore, to eliminate such toxic materials, such as nicotine and tar, various studies and researches have been progressed.

For example, the Korean patent No. 39934 and the U.S patent No. 4636182 discloses a cigarette filtering material made of a pine leaf to eliminate a toxic material and to add a flavor. In more, the Korean patent announcement No. 74-44 discloses a cigarette filtering material inserting a sponge layer and an adsorption layer to a pipe, and appending an adsorption material, such as an active charcoal or a bone charcoal of animals and plants mixed with an citric acid, between both layers of the sponge, to eliminate toxic materials such as tar or nicotine. Additionally, the Korean patent announcement No. 81-2064 discloses a cigarette filtering material adding a menthol flavor and zeolite to an acetate tow filter. In more, there is a manufacturing method of a mugwort cigarette adding a mugwort flavor or a dried mugwort leaf to a cigarette contents.

However, the conventional technology is insufficient to eliminate toxic materials of the cigarette, such as tar and nicotine. In more, it is expensive, and the manufacturing method is fastidious. In more, the smoker has a less favorite to such flavor.

DETAILED DESCRIPTION OF PREFFERED EMBODIMENTS

Reference will now be made in detail to preferred embodiments of the present invention, example of which is illustrated in the accompanying drawings.

The manufacturing method of a cigarette filtering material according to the preferred embodiment of the present invention comprises three steps comprising a ginkgo leaf sample manufacturing process, a pine leaf powder manufacturing process, and a manufacturing process mixing the gingko leaf sample, the pine leaf power and a flavor together. Each of the manufacturing processes is described in more detail one by one in the following statements.

[Ginkgo leaf sample manufacturing process]

As shown in Fig. 3, the ginkgo leaf sample manufacturing process performs a step of a ginkgo leaf collection to gather and to refine a flesh ginkgo leaf at first (step S10). Preferably, it is most effective to collect a ginkgo leaf on June or July every year, because most ginkgo leaves collected in this season contain a large amount of oleoresin, called ginkgo.

Kolophonium contained in the ginkgo extracted from the ginkgo leaf, having a peculiar taste and flavor, has an excellent adsorption to the residual available component of the cigarette smoke. Therefore, toxic materials in the cigarette smoke can be efficiently adsorbed and eliminated. Additionally, the ginkgo leaf contains a d-sesamin oil 2% fusing the toxic materials. Therefore, the d-sesamin oil can eliminate the toxic materials of the cigarette smoke. In more, because the ginkgo, the oleoresin, includes a water-soluble material called an isoginkgetin, a smoker can enjoy the flavor of the ginkgo. Additionally, the flavor of the main component of the isoginkgetin, called biaobanone, can be also enjoyed.

Secondly, the ginkgo leaf 100 kg refined from the collected ginkgo leaf is mixed and diluted with sodium nitride 0.1 - 0.2 kg and water 500 liter, and the mixed solution is precipitated during 24 hours. After precipitation, the mixed solution is fermented (step Sll). In this fermentation process, the amount of a chloroplast of the ginkgo leaf is reduced to 30 to 40 % amount of the original chloroplast.

Sequentially, after heating up the fermented ginkgo leaf sample in a sealed steam aging machine at the temperature of 100 to 110 °C about 2 hours, the step aging the ginkgo leaf sample is additionally performed in a unsealed steam aging machine about 30 to 40 minutes (step S12).

During the process extracting the ginkgo from the ginkgo leaf component, the flavor of ginkgo and the odious smell are eliminated, and about 80 to 90 % of kolophonium, the main component of the adsorptive material called abietin, is remained so that the cigarette toxic materials are adsorbed and removed.

On the contrary, the step adding a pine leaf powder to the aged sample can be applied (step S13). The process adding the pine leaf powder can be applied selectively, and it is possible to apply and to modify the first and the third process in Korean patent No. 39934. Sequentially, the aged sample is dried in a shade until the contained moisture is about 9 to 10 %, and is sterilized (step S14). In this case, the hot wind drier dries the aged sample steadily about 50 to 80 °C.

Sequentially, a grinding step is performed to grind the sterilized sample (step S15). In the grinding step, the size of the particle passes 10 to 20 meshes in the first grinding, and 200 to 350 meshes in the second grinding. Therefore, a predetermined ginkgo leaf sample is manufactured.

[Flavor manufacturing process]

A flavor is added to the granular cigarette filtering material of the manufacturing process of the present invention. As shown in Fig. 4, the manufacturing process mixes a licorice with water in the ratio of 1:20, and heats up the mixed solution more than 10 hours to get a juice (step S20).

Sequentially, after mixing the juice with brown sugar in the ration of 8:1, the juice is heated up again (step S21). h more, the juice is cooled down to get a flavor sample (step S22), and a little amount of tangerine juice is added to the flavor sample

(step S23). Therefore, the flavor sample is manufactured (the sugar content is about 8 to 9° Bx).

[Granular filtering material manufacturing process]

The granular filtering material manufacturing process is a final process to get a granular filter according to the present invention. As shown in Fig. 5, the ginkgo leaf sample 1 kg passing 200 to 350 meshes, gathered in the ginkgo leaf sample manufacturing process, is mixed with starch 0.1 kg passing 200 to 300 meshes, and with the flavor liquid formed in the flavor manufacturing process, so that the mixture contains 30 to 40 % of water. Finally, the mixture is kneaded (step S30).

Sequentially, a first heating process heats up the kneaded mixture at the temperature of 70 to 80 °C at 10 to 20 minutes (step S31). After the first heating process, the mixture is molded to a easily pulverized shape, and a second heating process (S32) is performed to heat and dry the mixture at the temperature of 40 °C until the mixture contains 3 % of water (step S32).

Sequentially, the dried mixture is ground to pass 35 to 45 meshes by a grinding mean having a mesh structure, such as an embossing toner (step S33). Therefore, with a ginkgo leaf as a raw material, a granular cigarette filtering material is manufactured The granular cigarette filtering material comprises a 70 to 90 weight % of a ginkgo leaf, an 8 to 10 weight % of starch, and up to 2 weight % of the flavor liquid. In more, the granular cigarette filtering material includes a large amount of oleoresin, called ginkgo, extracted from the ginkgo leaf to use an excellent adsorption ability of the component of the ginkgo, kolophonium, to eliminate tar and nicotine effectively. In more, the ginkgo leaf is used as a main raw material to use a peculiar flavor of bomylacetate The mixture of bomylacetate with a little amount of starch, based on the ginkgo leaf as a raw material, enhances the degree of strength of the granular particle, and contacts with high temperature minute liquids generated from the dry distillation in smoking a cigarette to eliminate a toxic material, such as tar or nicotine, more effectively. Normally, the temperature in smoking a cigarette is about 700 to 850 °C.

In more, the ginkgo leaf contains d-sesamin 2 % fusing the toxic materials of the cigarette, and a smoker can enjoy the flavor of biaobanone, main component of isoginkgetin contained in ginkgo. In more, by adding a flavor liquids containing licorice liquid as a main component, a smoker can enjoy the favorite more.

The cigarette having the granular filtering material according to the present invention is illustrated in Fig. 1 and Fig. 2. Naturally, another shape of a cigarette filter is possible, and the granule of the present invention can be mixed with the conventional cigarette filtering material.

Fig. 1 illustrates a triple filter, and Fig. 2 illustrates a double filter. The cigarette with the triple filter or the double filter comprises a cigarette leaf 10, an acetate tow 20, and a mixture 40 of 20 % of zeolite with 80 % of the cigarette filtering material of the present invention to a cavity between the cigarette leaf 10 and the acetate tow 20.

A rice paper 60 positioned in the mixture 40 includes numerous ventilation holes 50.

When a pine leaf sample is added to the cigarette filtering material of the present invention more, the ratio of the ginkgo leaf sample to the pine leaf sample is about 5:3.

Zeolite is added to the cigarette filtering material of the present invention to eliminate a toxic gas such as carbon monoxide CO. The ventilation hole 50 of the rice paper 60 is a minute hole to prevent tar generation, when the cigarette is smoked. As shown in the U.S patent No. 4,294,265, the fresh air from the outside is inhaled through the ventilation home 50 to prevent tar generation and to eliminate a toxic gas generated by the incomplete combustion of carbon monoxide CO, when the cigarette is smoked. Flavor, taste, and toxic materials of the cigarette is various according to the mixing ratio, when the cigarette filtering material is manufactured, and especially, according to whether an acetate tow is inserted or not. Because each tobacco company manufactures the cigarette to fit on the favorite of the smoker, the constituents and the effects can be a little different according to the cigarette manufacturer.

In the incomplete combustion of the cigarette due to inflaming temperature of 880 to 900 °C, when a cigarette is smoked, toxic materials, such as nicotine, tar, carbon monoxide CO, and hydrogen cyanide HCN are filtered by a filter tip. In more, the mixture of the ginkgo leaf, the pine leaf, and zeolite fuses and adsorbs the toxic materials.

The toxic gas itself is poisonous. Therefore, in adsorption of the toxic gas, ginkgo and terpentine resin is volatized to diffuse peculiar flavor of ginkgo terpentine (the mixture of a ginkgo leaf and a pine leaf) faintly. To the mixture of a ginkgo leaf and a pine leaf, licorice liquid can be added to fit on the favorite of the smoker.

The following tests compares 'This' (domestic cigarette), 'Malboro', 'Kent', and 'Winston' (foreign-made) with the test sample manufactured by inserting the filtering material of the present invention into the triple filter.

[Table 1]

In the above described experiment, The toxic material of the filtering material of the present invention has 8 to 15 % of difference, when comparing with that of the conventional filtering materials (Table 1). In other words, the experiment inserting the cigarette filtering material of the present invention between the middle of the conventional triple filter condenses the toxic materials, such as tar and nicotine, to reduce a shift ratio of the toxic materials to a human body rapidly. In more, even though the flavor of the cigarette filtering materials of the present invention can be milder than the flavor of the conventional filtering materials, the flavor of the present invention can be adjusted appropriately to fit on a smoker's favorite. In other words, when the cigarette is manufactured, the flavor and the toxic materials can be adjusted according to the weight of the injected material. To fit on the kind of the product, the sample granule of the filtering materials can be added more or less.

In Table 2, the filtering material, such as a ginkgo leaf, a pine leaf, and zeolite, passing through 10 to 30 meshes, is added to be 70 to 80 % in volume ratio of the cavity.

In more, when testing a single cigarette containing the cigarette filtering materials of the present invention, the condensed amount per the single cigarette is about 11.4 mg. In other words, the dark green color of the granular filtering material before inhalation is changed to bright black after exhalation. When sampling and inspecting the granule in the magnitude of more than 180 times through the microscope, the colorless tar of the surface of the spherical granule is changed to the heavy blank- brown color, and is adsorbed in various shapes generated by various temperature phenomena.

In more, the granule are condensed and stuck together in irregular, as if the heavy black tar acts as an adhesion layer for the granule. Therefore, the cigarette filtering materials according to the present invention have excellent adsorption ability to the toxic material, such as tar and nicotine, while a cigarette is smoked.

The filtering material according to the present invention uses excellent adsorption ability of kolophonium component in ginkgo to eliminate a toxic component of a cigarette, such as tar and nicotine. In more, the cigarette filtering material of the present invention mixes bomylacetate with a little amount of starch to enhance the degree of the strength of the granules to adsorb and to eliminate a toxic material, such as tar and nicotine, more efficiently. It is the reason that the mixed filtering material contacts with hot minute liquids generated by dry distillation phenomena, while a cigarette is smoked (The temperature in smoking a cigarette is about 700 to 850 °C)

In more, d-sesamin oil 2 % contained in the ginkgo leaf is able to fuse a toxic material in the cigarette, and a smoker can enjoy the flavor of biaobanone, the main component of isoginkgetin, while isoginkgetin is one component of ginkgo. In more, by adding flavor liquid containing licorice liquid as a main component, more appropriate flavor to fit on a regular smoker is produced.

While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention.
