Abstract

Using supercritical carbon dioxide(S-CO2) for extraction can omit solvent separation, improve extraction efficiency and reduce environmental pollution. Tobacco waste was used as a raw material for S-CO2 extraction in this research. The effects of tobacco waste type, extraction temperature(T) and extraction pressure(P) on the extraction yield were investigated by comparing the yield of tobacco extract. To explore the effects of different S-CO2 extraction parameters on the composition and content distribution of the principal aromatic components in tobacco extracts, the tobacco extracts were detected by using gas chromatography-mass spectrometry (GC-MS) and UV-fluorescence spectroscopy. The findings indicated that with the increase of extraction pressure, the extraction yield of tobacco increased significantly, but it had little effect on the types and content distribution of tobacco fragrances. Changing the temperature has little impact on tobacco extraction yield. The fragrance-causing components of tobacco extracts were more evenly distributed as the extraction temperature was raised. The rate of tobacco extraction can be accelerated by raising the extraction temperature within a specific range. With higher temperatures, the concentrations of acids and pyridine in tobacco waste extracts rose, but hydrocarbons decreased especially nicotine and cembratrien-diols content. Simultaneously, the distribution of tobacco fragrant ingredients was more uniform, and the scent was stronger.
