The invention provides a preparation method of Jin Tang tobacco
essential oil. The preparation method is characterized in that by adopting the combined technologies of subcritical extraction and molecular
distillation, the Jin Tang tobacco as a
raw material is extracted and separated, so that the content of volatile
aroma substances in the
essential oil is effectively improved. By applying the Jin Tang tobacco
essential oil into the cigarettes, the
aroma quality and the
mouthfeel of the cigarettes can be improved, and the sensory comfort of the cigarettes is improved; after the Jin Tang tobacco essential oil is applied to juice of electronic cigarettes, rich tobacco scent can be attached to the electronic cigarettes, so that the satisfaction is enhanced, and the disagreeable sweet feel of a
solvent is reduced. The preparation method and the application have the greatest advantages that (1) compared with the
steam distillation, the extraction rate of essential oil is greatly improved; (2) due to the
combined use of the subcritical extraction and molecular
distillation, the content of the nonvolatile
macromolecular substances in the essential oil is reduced, the content of volatile aromatic substances is improved, wherein the contents of
nicotine, solanone, neophytadiene, megastigmatrienone, farnesyl
acetone, and the like are obviously improved compared with those in the essential oil extracted by the subcritical extraction technology, and therefore, the characteristic
aroma of the tobacco is more outstanding.
