In this study, some vapor phase components formed during the tobacco roasting-process were identified by gas chromatography. Of the tobacco samples studied, the amounts of nicotine and benzyl alcohol were the highest. Volatiles occurring at 100C were generally less than those formed at 150C. It was observed that the amount of volatiles in Bitlis Sirmaçek Village tobacco was slightly higher than Muş Ahçivan tobacco roasted at the same temperature. Adsorption on alumina, sepiolite and silica gel and desorption of adsorbed components by diethyl ether extraction were investigated in order to recover volatile substances that can be used as cigarette flavorings from tobacco roasting. The adsorption and desorption activities of nicotine, 5-methylfurfural, acetol and pyridine, which are the main components in the vapor phase formed by the tobacco roasting process, were investigated. In addition, the components adsorbed on silica gel were recovered by an organic solvent extraction method. Recovery by carbon disulfide extraction showed maximum efficiency and many volatile compounds, especially sugar-like thermal decomposition products, were recovered in good yield. Adsorption efficiencies of adsorbents are discussed with their raw material, specific surface area, micropore size distribution and affinity of volatile components.
