Benefits of technology

[0008] Accordingly, 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.
[0010] More specifically, according to a first aspect of the present invention, there is provided 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.
[0011] According to a second aspect of the present invention, there is provided 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.

Problems solved by technology

Natural tobacco material exhibits undesired tastes such as stimulus and pungency.
However, 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.

Analytical Method for the Present Causal Component

[0068] As an index of the decrease of the present causal component, a simple analytical method for the present causal component was established by using a high performance liquid chromatography. 1.0 g of Burley tobacco material (in the case of the extract liquid, pulverized was the extracted liquid, lyophilized one in an amount corresponding to 1.0 g of the tobacco material) was pulverized, to which 10 mL of 0.1M aqueous solution of sodium acetate was added. The mixture was stirred at room temperature for 30 minutes, filtered and subjected to centrifugal separation. The supernatant was passed into a reverse phase solid phase extraction cartridge (Oasis HLB (6 cc, 500 mg, Waters Inc.), washed with water and eluted with 10 mL of acetonitrile / water (6 / 4). The eluate was concentrated under a reduced pressure to remove the acetonitrile, passed into a mini column of a polyvinyl pyrrolidone resin (Polycler VT (Wako Junyaku K.K.)) and then ...

example 2

[0079] The filtrate (0.5 L, corresponding to 75 g of the raw material) obtained in the Reference Example was subjected to centrifugal separation (3,000 rpm, 10 minutes) so as to remove the insoluble portion and, then, subjected to an ultrafiltration treatment by using an ultrafiltration disk using a semipermeable membrane made of a regenerated cellulose having a fractionating molecular weight cutoff of 10,000 daltons (Ultracell PLGC ultrafiltration disk, Millipore Inc., nominal molecular weight cutoff of 10,000 daltons). The yields of the permeate and the concentrated liquid, after lyophilization, were 12.8 g and 2.1 g, respectively. The lyophilized material of the permeate was dissolved in 50 mL of water, and the total amount of the resultant solution was sprayed onto the shreds obtained in the Reference Example to obtain regenerated tobacco shreds. Cigarettes were made as in the Reference Example by using the regenerated tobacco shreds.

example 3

[0080] The filtrate (0.5 L, corresponding to 75 g of the raw material) obtained in the Reference Example was subjected to centrifugal separation (3,000 rpm, 10 minutes) so as to remove the insoluble portion, and added with 50 mL (volume of wet resin) of an anion exchange resin (DEAE Cellulofine available from Seikagaku Kogyo K.K.) to carry out adsorption by stirring, followed by filtration. The processed liquid was concentrated under a reduced pressure, and the total amount of the concentrate was sprayed onto the shredded tobacco obtained in the Reference Example to obtain regenerated tobacco shreds. Cigarettes were made as in the Reference Example by using the regenerated tobacco shreds.
