  • This study was carried out to determine the relationship between smoke components and sensory evaluation by changes tobacco leaf blending. Seven different cigarettes were made by adding different types of oriental, reconstituted and expanded tobacco leaves. 62 kinds of smoke components which were 6 of general components, 34 of semi-volatile and volatile components, 9 of acid components, and 13 of phenolic components were analyzed. Eight kinds of sensory item were evaluated and also electronic nose system data was collected. All smoke components and sensory characteristics of mainstream smoke were changed by the different blending. To determine the relationship between smoke components and sensory test, the correlation and regression analysis were carried out by using SPSS statistical program. Tar, pH, and CO showed a high correlation with sensory evaluation item. As tar related to hotness, CO have a high correlation with offensive aroma. Semi-volatile and volatile components of smoke related to sensory characteristics such as aroma, taste, irritation, hotness and smoothness. When propylene, l,3-butadiene, butane, isoprene, and 2-methylfuran showed a high correlation with aroma; methyl chloride, methanol, toluene, ethyl benzene showed a high correlation with irritation. Some acidic components and phenolic components of smoke also had a high relation to smoke volume. Especially the acidic components such as 2-furoic acid, 2-hydroxybutyric acid, phenylacetic acid and palmitic acid; the phenolic components such as 4-vinyl phenol, pyrocatechol, 3-methyl catechol, hydroquinone showed a high correlation with smoke volume. As using regression analysis, it was possible to estimate the results of sensory evaluation from the smoke analysis data. From the results of electronic nose system analysis, we can find the different pattern by adding expanded tobacco leaf.

  • A comparative study of major brands of domestic and imported cigarettes saled in market has been conducted. The total amounts of total particulate matter(TPM), tar and nicotine delivered from cigarettes, as well as the amounts of tar, nicotine in puff by puff were determined in the mainstream smoke of 6 brands. In addition, the relative amounts of vapour phase in 3rd puff smoke were determined. Results showed that the amounts of TPM and tar delivered from domestic brands were similar to the imported brands and the amounts of total nicotine delivered from domestic brands were higher than those of imported brands. As the domestic cigarettes nicotine/tar(N/T X 100) ratio was 9.5-10.3, the imported one's was 5.6-8.1. However, the amounts of tar and nicotine in puff by puff for the domestic brands were lower than those of the imported cigarettes and the relative amounts of vapour phase in 3rd puff smoke for the domestic cigarettes were lower than those of the imported cigarettes.

  • In this study, we investigated the existence of melamine and cyanuric acid in cigarette smoke because leaf tobacco contains lots of nitrogen compounds and they are capable of pyrolytic synthesis while smoking. The extraction and derivatization conditions of two compounds were performed according to the procedure of U.S. Food and Drug Administration(FDA). Ky3R4F as reference cigarette was smoked on ISO condition(Puff volumne : 35 ml, duration : 60 sec, Interval : 2 sec). Compared with the results Ky3R4F and standard solution, retention time of two compounds was not corresponded. As a result, we concluded that melamine and cyanuric acid were not existed in cigarette smoke.
