Adsorption of Volatiles from Roasted Tobacco on Activated Carbon and Desorptive Recovery by Ether Extraction

Abstract

In order to recover the volatiles which can be used as cigarette flavor ingredients from tobaccoroasting treatment, adsorption on activated carbon and desorption by ether extraction were studied. Adsorption efficiencies were varied by physical properties of the activated carbons, i.e., raw material, specific surface area, acetone adsorption capacity, and micro pore size distribution. The affinities of volatile components for activated carbon are discussed with their adsorption efficiencies. Most of the volatiles adsorbed on activated carbon were recovered by diethyl ether extraction. Especially, thermal degradation products from sugar analogues were recovered in a good yield.
