- the filter-tipped cigarette thus manufactured was subjected to smoking, and the adsorption ability of the filter with respect to acetone in the mainstream smoke was investigated.
- an apparatus 70 illustrated in FIG. 7 was used in order to trap components contained in the mainstream smoke of a cigarette.
- This apparatus 70 has a trapping device for trapping particulate matter 71 comprising a Cambridge filter 711 (a diameter of 47 mm), a tobacco mainstream smoke inflow port 71a, which holds a cigarette CIG, and a tobacco mainstream smoke outflow port 71b.
- the apparatus 70 comprises an impinger 72.
- a trapping agent solution TA for trapping gaseous components in the tobacco mainstream smoke is contained in the impinger 72.
- the impinger 72 was accommodated in a Dewar bottle 73 containing a refrigerant RM for maintaining the trapping agent solution TA at a low temperature.
- a mixture of dry ice and isopropanol was used as the refrigerant RM, and the temperature of the trapping agent solution TA was maintained at -70°C or lower during the experiment.
- the outflow port 71b of the trapping device 71 for trapping particulate matter was connected with a pipe line 74 extending into the trapping agent solution TA in the impinger 72.
- a suction port 76a of an automatic smoking machine 76 was connected with a pipe line 75 extending to the upper space of the trapping agent solution TA in the impinger 72.
- the pressure inside the impinger 72 was reduced by suction via the pipe line 75.
- the mainstream smoke of the tobacco passed through the Cambridge filter 711 in the trapping device 71.
- the particulate matter in the mainstream smoke of the tobacco was trapped in the Cambridge filter 711, and the particulate matter-deprived mainstream smoke was introduced into the trapping agent solution TA in the impinger 72 via the pipe line 74. Bubbling occurs in the trapping agent solution TA, and the gaseous matter in the mainstream smoke is trapped in the trapping agent solution TA.
- the cigarette was set to the trapping device 71, and subjected to smoking using the automatic smoking machine 76 under the standard smoking conditions defined by International Organization for Standardization (1 puff: 35 mL puff for 2 seconds, puff interval: 58 seconds).
- the agent solution in the impinger 72 was transferred to a serum vial, and the Cambridge filter 711, in which the particulate matter was trapped, was also put into the serum vial. It was subjected to a shaking extraction at 250 times/min for 30 minutes. 1 mL of the obtained extract was put into a vial for gas chromatograph-mass spectrometer (GC/MS), and the components in the mainstream smoke were analyzed under the following conditions.
- GC/MS gas chromatograph-mass spectrometer
- a cigarette having a plain filter that is, the cigarette having a cigarette rod of a commercially available filter-tipped cigarette product, "Winston Lights", and a plain filter consisting of a cellulose acetate fiber tow (length: 20 mm; 2.5Y/70000) connected to one end thereof; hereinafter, this will be referred to as a "standard cigarette" and the above control cigarette.
- the value of acetone peak area for each of the cigarettes was calculated.
- Each of the values of acetone peak area for the filter-tipped cigarette including flavorant-carrying activated carbon particles and the control cigarette was divided by the value of acetone peak area for the standard cigarette.
- the obtained value was multiplied by 100 to obtain the acetone decreasing rate (%) for each of the filter-tipped cigarette including flavorant-carrying activated carbon particles and the control cigarette.
- the acetone decreasing rate (%) was subtracted from 100% to obtain the acetone adsorption rate.
- the acetone adsorption rate with respect to the control cigarette was 48%
- the acetone adsorption rate with respect to the filter-tipped cigarette including flavorant-carrying activated carbon particles was 45%.
- This result indicates that when a flavorant-carrying activated carbon particle is prepared using activated carbon having a BET specific surface area of 1700 m 2 /g as a core particle, the flavorant-carrying activated carbon particle has an adsorption ability corresponding to about 94% with respect to the intrinsic adsorption ability of the core particle.
- a core particle having a specific surface area of 700 m 2 /g or greater exhibits a high adsorption ability with respect to the components contained in the mainstream smoke of a cigarette, and a core particle having a specific surface area of less than 700 m 2 /g exhibits a low adsorption ability with respect to the components contained in the mainstream smoke of a cigarette.
