Description

Method of manufacturing tobacco

The present invention relates to a method for manufacturing tobacco, and more particularly, by lowering the temperature of the combustion of tobacco to minimize the amount of harmful substances contained in the tobacco smoke, which contributes to the promotion of health of smokers. It relates to a method for producing tobacco for reducing harmful substances.

Generally, tobacco is produced by processing the tobacco leaf in a predetermined process, and divided into cigarettes (cigarettes), cigars (gae: cigar), gamyeon (刻 煙) according to the shape. The popularity of cigarettes has been relatively short, and until then, mainly smoked or smoked cigarettes. Recently, filter cigarettes, which can lower nicotine and tar ingredients, have become popular in the world.

Tobacco is generally processed and manufactured in an automated mechanical facility. Looking at the manufacturing process, the first step is to combine the raw tobacco leaves. Here, the compounding is intended to give characteristics and unify the quality by mixing in an appropriate ratio in consideration of the aroma and taste characteristics of various leaf tobacco, the basic taste and aroma of the product is determined by the formulation and flavor. The mixing ratio of these raw materials is different depending on the type of product.

When the blending of raw materials is completed, it is processed. The processing consists of flavoring and heat treatment (toasting). Among these processes, flavoring and flavoring agents such as sugars and fragrances are added to the raw material blends to improve the taste and quality of tobacco. The operation | work which adds moisturizers, such as glycerin, is performed. At this time, the fragrance is generally divided into a primary fragrance and a secondary fragrance by selecting a fragrance suitable for the blending of tobacco.

After processing, the processed raw materials are carved out and manufactured into cigarettes. In cigarette makers, leaf tobacco is rolled into cigarette paper to create a membrane-free cigarette. Membrane cigarettes are connected to the filter by the tip paper in the filter attacher and becomes a filter cigarette. After this is done, the product is packaged to protect tobacco products, facilitate storage and transportation, and increase the value of the goods.

On the other hand, as the disease problem caused by smoking has recently emerged as a social problem, there is a low content of harmful ingredients such as nicotine, tar and tobacco nitrosoamines (TSNA) in the smoke, but the inherent taste of tobacco remains intact. The tendency to prefer tobacco is increasing. Tobacco nitrosoamines typically include N -Nitrosonornicotine (NNN), 4 (N-Nitrosomethylamino) -1-(3-pyridinyl) -1-butanone (NNK), N -Nitrosoanatabine (NAT), and N -Nitrosoanabasine (NAB). ).

According to this preference trend, there is a demand for a method of preparing various tobaccos that can maintain the intrinsic tobacco taste while having a low content of nicotine and tar. Due to this demand, many methods for removing or reducing harmful smoke components have been studied. In this regard, methods for reducing nitrosamines in smoke include microwave treatment for product cigarettes (CN 1269992A, Oct. 18, 2001), reduction by zeolite treatment on kerosene (Microporous and Mesoporous 33, 307-310, 1999). ), A radiation method (US 6,311,605 B1) to leaf tobacco before treatment is known.

However, the above methods require a separate facility, and when the zeolite is treated on the vinegar, it is difficult to uniformly disperse the powder, and because the vinegar and the zeolite powder are mixed with each other because they are not compatible with each other, they are mixed. In order to solve this problem, a retention aid must be treated.

Accordingly, the present inventors pay attention to the fact that a change in the components contained in the smoke occurs when the combustion temperature of the cigarette is changed, lowering the temperature of the combustion of the cigarette to minimize the content of harmful substances contained in the cigarette smoke After studying the manufacturing method, the present invention was completed.

Therefore, an object of the present invention is to provide a method for manufacturing a cigarette that can lower the combustion temperature of the cigarette to minimize the content of harmful substances contained in the smoke.

In order to achieve the above object, the present invention is treated with a dibasic organic acid selected from potassium citrate, potassium malate, potassium tartrate, potassium oxalate in the process of blending and then processing the tobacco raw material In the tobacco production method for producing a cigarette, the dibasic organic acid is treated with a spray solution prepared by dissolving in a solvent such that the% concentration of alkali metal is 1 to 15% based on 100 parts by weight of the raw material blend. It provides a method for producing tobacco, characterized in that the treatment by spraying 10 parts by weight.

Hereinafter, the cigarette according to the present invention will be described in more detail with reference to the manufacturing method as follows.

In the present invention, in the method of manufacturing a tobacco by blending the tobacco raw material and then processing the same, it is characterized in that the tobacco raw material blended in the process of processing the tobacco raw material is treated with a dibasic organic acid.

When the tobacco raw material mixture is treated with a dibasic organic acid, the dibasic organic acid is decomposed by high temperature while smoking, and is decomposed into carbonate and water, and the decomposition product causes a decrease in combustion temperature during smoking. As such, the lowering of the combustion temperature may lead to the reduction of harmful components such as nicotine, tar, and nitrosoamine, thus contributing to the maintenance of smoker's health.

In more detail, the principle is that the implementation of harmful components in mainstream smoke is carried out by direct transfer of harmful components in the leaf tobacco or by high temperature thermal synthesis. Therefore, when the combustion temperature is lowered, the transition and thermal synthesis of harmful components are reduced, thereby inducing the reduction of harmful components that transfer to smoke.

At this time, it is preferable to use a dibasic organic acid selected from an organic acid containing a monovalent or divalent alkali metal, and more preferably use an organic acid in which the alkali metal is potassium. As the dibasic organic acid in which the alkali metal is potassium, it is preferable to use one selected from potassium citrate, potassium malate, potassium tartrate, and potassium oxalate.

The dibasic organic acid described above may be treated through various methods, but preferably, the dibasic organic acid is dissolved in a solution after the first flavor to make a spray liquid having an alkali metal concentration of 1 to 15%, and the spray liquid is used as a raw material. It is preferable to spray by 2-10 weight part with respect to 100 weight part of formulations.

At this time, when the concentration of alkali metal in the spray liquid is less than 1%, the excess alkali metal solution needs to be sprayed in order to be treated with a dibasic organic acid of a desired concentration in the raw material compound, so that the water content of the raw material compound is too high to cause problems in the process. If the concentration of the alkali metal in the spray liquid exceeds 15%, the viscosity of the spray liquid is too high, so that it is difficult to uniformly spray the raw material mixture, it is preferable to spray the solution using a solution prepared within the above range. Do.

In addition, the spray solution prepared to have a concentration within the above range is less than 2 parts by weight based on 100 parts by weight of the raw material mixture when the treatment is effective in reducing the combustion temperature of the product tobacco, spraying to be treated to exceed 10 parts by weight In this case, the rate of burning cigarettes is rather reduced to increase the number of cigarette smoking (puff No.), thereby increasing the amount of tar and nicotine in the smoke components. Therefore, it is good to treat the spray liquid within the above range.

The spray liquid may be treated by spraying in a conventional processing, preferably, may be carried out before or after the primary perfume treatment or mixed with the perfume liquid during the primary perfume treatment. When the treatment is completed, if the cigarette is manufactured according to a conventional tobacco production process, the manufacture of tobacco is completed.

The cigarette produced in this way is decomposed in the form of metal oxides, carbonates and water in the dibasic organic acid contained in the smoking, this degradation product causes a reduction in the combustion temperature, thus nicotine or tar contained in the smoke And harmful components such as nitrosoamines (NNN, NAT, NAB, NNK, etc.). As such, by lowering the combustion temperature of the cigarette, it is possible to help the health of the smoker by inducing a decrease in the amount of harmful components contained in the smoke.

Hereinafter, the present invention will be described in detail with reference to the following examples, which are presented to aid the understanding of the present invention, but the present invention is not limited thereto.
