Effects of Smoking Environments on Chemical Property and Sensory Quality of Mainstream Cigarette Smoke

In order to investigate the influence of regional environment on the chemical property and sensory quality of cigarette smoke,the cigarette samples of "Shuangxi" brand were separately smoked in Guangzhou,Anyang,Shenyang and Yuxi,the routine chemical analytes and aromatic components in MCS were tested,and their sensory quality was evaluated.The results showed that:1) The samples smoked in Guangzhou presented the highest tar content and the lowest pH.They presented the lowest tar,but the highest moisture content and pH value in Yuxi,and the lowest moisture content in Shenyang.The nicotine content in MCS was basically identical in the four cities.2) Comparing with smoking in Guangzhou,the MCS delivered more micromolecular aromatic components,but less macromolecular aromatic components while smoking in Anyang and Shenyang;the MCS delivered less macromolecular aromatic components,but the delivery of micromolecular aromatic components was variable while smoking in Yuxi.3) Comparing with smoking in Guangzhou,the smoke was more irritant in Anyang,less in smoothness and comfortableness and more irritant in Shenyang,and the flavor note changed somewhat in Yuxi.
