Sažetak
In the past few decades, Supercritical Fluid Extraction (SFE) using CO2 as a solvent has gained wide acceptance as an alternative technique to conventional solvent extractions for separation of active compounds from different plant materials including tobacco, as a most produced non-food crop in the world. Tobacco contains more than 4000 compounds, together with particles and gases where a large part of them are delivered during smoking. The complex chemical composition is important factor in valuing tobacco as an interesting extraction material. Tobacco waste, such as agricultural and industrial waste (scrap, dust, midrib) have similar chemical composition as tobacco leaves because they are derived directly during processing of tobacco. At the same time, tobacco waste can represent the potential, highly valuable and cheap material, rich in some bioactive compounds. SFE have been already implemented in tobacco processing industry for removing nicotine and producing low nicotine tobacco, but recently some other application for extraction of solanesol and aroma compounds were also developed. This chapter provides an overview on the principal applications related to SFE of active compounds from tobacco and tobacco waste emphasizing the influence of the most important processing parameters (pressure, temperature, time, solvent flow rate, particle size and co- solvents) on the extraction yield of the most important compounds and their possible application. The application of SFE in separation of active compounds from tobacco and tobacco related materials, represents a new promising and environmentally friendly technique for the production of biologically active compounds, especially nicotine, solanesol and volatile compounds which could be further incorporated into new high-value products.
