Definitions
- the present invention relates to the field of improving the flavor and taste of tobacco, and more particularly, relates to a tobacco material, a flavoring agent, and a regenerated tobacco, which are reduced in stimulus and pungency in the smoking stage, and also relates to a method of preparing the tobacco material and a method of preparing the tobacco flavoring agent.
- Natural tobacco material exhibits undesired tastes such as stimulus and pungency.
- Burley tobacco is strong in the undesired tastes such as stimulus and pungency and, thus, various improvements have been applied to the tobacco by means of, for example, addition of a perfume or by a heat treatment.
- the causes of the undesired tastes have not yet been clarified.
- the perfume technology and the treating method employed in the past for improving the tobacco taste are based on experiences and are unsatisfactory in terms of the efficiency and the cost ( Tobacco Reporter, July 2003, pp. 64-70 ).
- the component causing the stimulus and the pungency in natural tobacco material can be chemically clarified, it is considered possible to efficiently improve the flavor and taste of natural tobacco material by applying an appropriate treatment for decreasing the components in question.
- an object of the present invention is to provide, by chemically clarifying the component causing the stimulus and pungency in natural tobacco material, particularly Burley tobacco, measures to decrease the component causing the stimulus and pungency in view of the physical and chemical properties of the component, thereby improving the flavor and taste of the natural tobacco material.
- the present inventors have fractionated an aqueous extract liquid of Burley tobacco by various chromatographic technologies, and made cigarettes by using each fraction. Then, the component causing the stimulus and pungency was purified, based on the expression of the stimulus and pungency by an organoleptic evaluation. As a result, it has been clarified that the component causing the stimulus and pungency (hereinafter referred to as "present causal component”) is a colored acidic water-soluble polymer substance that is contained in the aqueous extract liquid. In the process of the fractionation purification, the physical and chemical properties leading to the development of a method for decreasing the present causal component have been clarified.
- the present causal component since the present causal component is non-volatile, it is thus considered that the present causal component does not directly produce the stimulus and pungency, and is a precursor component which produces the components generating the stimulus and pungency in the smoking stage.
- the present invention is based on these findings.
- a tobacco material characterized in that the stimulus and pungency in the smoking stage have been reduced by decreasing the content of a colored acidic water-soluble polymer substance.
- a tobacco flavoring agent characterized by containing a tobacco extract liquid reduced in the component causing the stimulus and pungency by decreasing the content of a colored acidic water-soluble polymer substance.
- a regenerated tobacco material characterized in that it comprises a regenerated tobacco web comprising fibers, which are an extraction residue of natural tobacco material, added with a flavoring agent comprising an aqueous extract liquid from natural tobacco material, and the flavoring agent is a flavoring agent according to the present invention.
- a method of preparing a tobacco material characterized by decreasing a colored acidic water-soluble polymer substance.
- a method of preparing a flavoring agent characterized by decreasing a colored acidic water-soluble polymer substance from an aqueous extract liquid of natural tobacco material.
- Burley tobacco material was extracted with an aqueous solvent to obtain an extract liquid.
- the extraction residue consists essentially of fibers.
- the extraction residue was formed into a slurry by an ordinary method, and the slurry was made into a regenerated web sheet, which was shredded to obtain regenerated tobacco shreds.
- the extract liquid noted above was treated with an ultrafiltration membrane having a molecular weight cutoff of 10,000 daltons to obtain a fraction having a molecular weight lower than 10,000 daltons and another fraction having a molecular weight not lower than 10,000 daltons.
- the fraction having a molecular weight lower than 10,000 daltons was concentrated and, then, added to the regenerated tobacco shreds noted above, followed by preparing cigarettes by using the resultant tobacco shreds.
- the cigarettes were subjected to an organoleptic examination, and there was obtained an evaluation that the smoking taste was markedly improved in that the stimulus and pungency were scarcely felt, compared with the cigarettes prepared by using the regenerated tobacco shreds to which was added the extract liquid itself as it was. From this result, it was estimated that the present causal component would be contained in the water-soluble polymer fraction having a molecular weight not lower than 10,000 daltons.
- each fraction was subjected to an ultrafiltration treatment with a molecular weight cutoff of 10,000 daltons in each of the following purification stages so as to carry out the evaluation in respect of the components having a molecular weight not lower than 10,000 daltons.
- evaluation cigarettes described below were prepared by using each fraction, and an organoleptic test was conducted on the evaluation cigarettes so as to permit the fractionation to proceed, with the expression of the stimulus and pungency used as an index.
- the evaluation cigarettes added with each fraction were evaluated by the organoleptic evaluation performed by 10 expert panels as to whether the stimulus and pungency were expressed, compared with control cigarettes added with purified water alone.
- Cigarettes the same as commercially available cigarettes very low in nicotine and tar contents (1 mg of tar, and 0.1 mg of nicotine) except that no perfume was added were used as the evaluation cigarettes. These cigarettes exhibited a tendency that the tasting effect was small relative to the amount of the perfume added thereto. However, these cigarettes were substantially free from the effect of the cigarettes themselves on the taste and, thus, a satisfactory result was obtained in terms of the judgment of the tasting effect of each fraction.
- each fraction was added by dissolving the fraction derived from 20g of Burley tobacco material in 1 mL of purified water and by injecting 10 ⁇ L of the solution (corresponding to the fraction derived from 0.2g of the tobacco material) into the evaluation cigarette by using a syringe.
- the amount of the tobacco shreds per cigarette was about 0.6g and each fraction was added in an amount corresponding to about 1/3 of the amount of the tobacco shreds.
- Midribs petiole, thick vein portions of the leaf
- Burley tobacco are thin in taste and prominent in the stimulus and pungency and, thus, used as the object of the study.
- Midribs of Burley tobacco material were pulverized and the extraction was conducted by stirring at room temperature for 30 minutes in a 0.1M sodium acetate aqueous solution, which was 10 times as much in volume as the midribs.
- the extract liquid was filtered and, then, subjected to centrifugal separation to remove the fine powdery material. This extract liquid was put into a column of a reverse phase adsorbing material, and the column was washed with water.
- the eluate was subjected to an ultrafiltration (a molecular weight cutoff of 10,000 daltons) to remove the low molecular weight components, washed with water and lyophilized. Further, the lyophilized material was subjected to fractional precipitation with methanol/water (9/1) and, then, subjected to centrifugal separation to remove the polysaccharides and proteins that were precipitated. The supernatant was concentrated under a reduced pressure and lyophilized, giving a final purified product. The final purified product of the present causal component was obtained from the raw material at a yield of about 0.2%. It was confirmed by all of the 10 expert panels that the stimulus and pungency peculiar to Burley tobacco were expressed from the evaluation cigarette having no perfume added thereto, but added with the final purified product at a concentration of about 400 ppm.
- FIG. 1 shows a gel filtration high performance liquid chromatogram of the present causal component (see Example 1 below).
- the present causal component has a molecular weight of 10,000 to 60,000 daltons and its peak molecular weight was 16,000 daltons.

- pectin, proteins, etc. i.e., the other water-soluble polymers contained in tobacco
- the present causal component is soluble in a water-containing alcohol.
- FIG. 3 shows the infrared absorption spectrum of the present causal component. As shown in FIG. 3, the present causal component exhibits absorption peaks at 3423, 2935, 1618, 1411, 1261, 1070, and 534 cm -1 .
- the feature of the ultraviolet visible absorption spectrum of the present causal component resembles that of a brown polymer, which is called melanoidin, contained in general foods.
- melanoidin contained in foods Various researches have been conducted on melanoidin contained in foods.
- the Maillard (non-enzymatic browning) reaction of sugars and amino acids, and the oxidative polymerization reaction (enzymatic browning reaction) of polyphenols caused by the enzyme are said to be involved in the formation of melanoidin.
- melanoidin has different chemical composition and properties and, thus, the general chemical structure of melanoidin has not yet been confirmed (see Science of Food as Viewed from Color, compiled by Kazuhiko Takamiya, pp. 183-191 (2004 ), and Science of Starch, vol. 38, No. 1, pp. 73-79 (1991) .
- a colored component contained in Burley tobacco material is called a brown pigment and resembles the present causal component in the chemical properties.
- Chemical studies have been conducted on the brown pigment. It is considered in Arch. Biochem. Biophys., 86, 94-101 (1960) and Arch. Biochem. Biophys., 93, 580-590 (1961) that the brown pigment is a polymer component formed of an oxidatively polymerized material (enzymatic browning reaction) of polyphenols (chlorogenic acid and rutin) conjugated with proteins, iron ions, etc. It has been clarified by the subsequent studies that the brown pigment contained in tobacco can be classified into several kinds differing from each other in the chemical composition (see J. Agric. Food Chem., 26 (1978), 380-385 ).
- the colored acidic polymer component (present causal component) contained in natural tobacco material, particularly, in Burley tobacco material, expresses the stimulus and pungency inherent in Burley tobacco. It has also been clarified that the chemical properties of the present causal component resembles those of melanoidin and the component called brown pigment component of tobacco.

- the extraction residue used may be the one obtained as a result of the extraction treatment directly intended to prepare the tobacco flavoring agent of the present invention, or may be the one obtained by the extraction of natural tobacco material intended for the other purposes.
- the decreasing methods directly utilize the physical and chemical properties of the present causal component. That is, the flavor and taste can be improved by effectively decreasing the present causal component utilizing the physical and chemical properties that the causal component is a polymer substance having a molecular weight of 10,000 to 60,000 daltons, that its polarity is low compared with that of tobacco components such as pectin, and that the present causal component is an acidic water-soluble polymer substance.

- the removing operation can also be performed by a dialysis method or a gel filtration method.
- the fraction having a molecular weight lower than 1,000 daltons, preferably lower than 10,000 daltons, can be used as the tobacco flavoring agent.
