Abstract
The present invention relates to a process for providing a tobacco extract. A tobacco material is provided in contact with an extraction solvent. The temperature of the tobacco material and liquid extraction solvent is reduced to below the freezing point thereof to provide a frozen mixture. The temperature of the frozen mixture is then raised to provide a melted portion including the tobacco extract within the liquid extraction solvent. The extract within the solvent preferably has a high soluble solids content (e.g., at least 10 percent by weight of the total weight of the melted portion). If desired, the tobacco extract within the extraction solvent can be further treated (e.g., chemically or physically) to provide or isolate flavorful and aromatic tobacco-derived components of tobacco extract.
