Abstract

The invention relates to the essential oil of tobaccos as well as a preparation method and application thereof to cigarettes. The essential oil of the tobaccos is prepared by the following method of: taking discarded/defective tobacco wastes, extracting by an organic solvent, taking the crude extract of the essential oil, introducing water vapor, condensing and separating oil and water so as to obtain the essential oil of the tobaccos. By adding the essential oil of the tobaccos, which is disclosed by the invention and is used as a flavoring agent, into the tobacco shreds of cigarettes, the self fragrance of the tobaccos can be increased, the quality of the fragrance of the cigarettes is enhanced, the excitation and the miscellaneous gas of the tobaccos are reduced, and smoke is softened. The essential oil of the tobaccos as well as the preparation method and the application thereof to the cigarettes have the advantages that the advantage of higher extracting yield of a solvent extracting method and the characteristic of refinement of a water-vapor distillation extracting method are combined, the yield of the essential oil of the tobaccos is obviously higher than that of a traditional water-vapor distillation method, and extracting equipment and a solvent are simple and convenient and are easy to obtain; and moreover, no solvent residue exists in a final product of the essential oil of the tobaccos, and the safety of the product is high.

Description

technical field [0001] The invention relates to the extraction and application fields of natural plant essential oils, in particular to a tobacco essential oil, its preparation method and its application in cigarettes, in particular to the preparation of tobacco essential oils by utilizing the waste waste generated in the cigarette production process. Background technique [0002] Tobacco is the whole herb of Nicotiana tabacum L., a plant of the genus Nicotiana in the family Solanaceae, harvested in autumn and dried in the shade. Tobacco, as an important hobby economic crop, plays an important role in the global agriculture. Since the 1950s, the world's cigarette industry has been subjected to increasingly severe public opinion pressure on smoking and health. Improving the safety of smoking has become a common goal of the tobacco industry. After years of research, people focused on reducing the tar in cigarettes to improve smoking safety. So reducing the amount of tar in c...
